KENNEDY SPACE CENTER, Florida—Preparations for the first human spaceflight to the Moon in more than 50 years took a big step forward this weekend with the rollout of the Artemis II rocket to its launch pad.

The rocket reached a top speed of just 1 mph on the four-mile, 12-hour journey from the Vehicle Assembly Building to Launch Complex 39B at NASA’s Kennedy Space Center in Florida. At the end of its nearly 10-day tour through cislunar space, the Orion capsule on top of the rocket will exceed 25,000 mph as it plunges into the atmosphere to bring its four-person crew back to Earth.

“This is the start of a very long journey,” said NASA Administrator Jared Isaacman. “We ended our last human exploration of the moon on Apollo 17.”

The Artemis II mission will set several notable human spaceflight records. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen will travel farther from Earth than any human in history. They won’t land. That distinction will fall to the next mission in line in NASA’s Artemis program.

But the Artemis II astronauts will travel more than 4,000 miles beyond the far side of the Moon (the exact distance depends on the launch date), setting up for a human spaceflight speed record during their blazing reentry over the Pacific Ocean a few days later. Koch will become the first woman to fly to the vicinity of the Moon, and Hansen will be the first non-US astronaut to do the same.

“We really are ready to go,” said Wiseman, the Artemis II commander, during Saturday’s rollout to the launch pad. “We were in a sim [in Houston] for about 10 hours yesterday doing our final capstone entry and landing sim. We got in T-38s last night and we flew to the Cape to be here for this momentous occasion.”

The rollout began around sunrise Saturday, with NASA’s Space Launch System rocket and Orion capsule riding a mobile launch platform and a diesel-powered crawler transporter along a throughway paved with crushed Alabama river rock. Employees, VIPs, and guests gathered along the crawlerway to watch the 11 million-pound stack inch toward the launch pad. The rollout concluded about an hour after sunset, when the crawler transporter’s jacking system lowered the mobile launch platform onto pedestals at Pad 39B.

Hitting the launch window

The rollout keeps the Artemis II mission on track for liftoff as soon as next month, when NASA has a handful of launch opportunities on February 6, 7, 8, 10, and 11.

The big milestone leading up to launch day will be a practice countdown or Wet Dress Rehearsal (WDR), currently slated for around February 2, when NASA’s launch team will pump more than 750,000 gallons of super-cold liquid hydrogen and liquid oxygen into the rocket. NASA had trouble keeping the cryogenic fluids at the proper temperature, then encountered hydrogen leaks when the launch team first tried to fill the rocket for the unpiloted Artemis I mission in 2022. Engineers implemented the same fixes on Artemis II that they used to finally get over the hump with propellant loading on Artemis I.

So, what are the odds NASA can actually get the Artemis II mission off the ground next month?

“We’ll have to have things go right,” said Matt Ramsey, NASA’s Artemis II mission manager, in an interview with Ars on Saturday. “There’s a day of margin there for weather. There’s some time after WDR that we’ve got for data reviews and that sort of thing. It’s not unreasonable, but I do think it’s a success-oriented schedule.”

The Moon has to be in the right position in its orbit for the Artemis II launch to proceed. There are also restrictions on launch dates to ensure the Orion capsule returns to Earth and reenters the atmosphere at an angle safe for the ship’s heat shield. If the launch does not happen in February, NASA has a slate of backup launch dates in early March.

Ars was at Kennedy Space Center for the rocket’s move to the launch pad Saturday. The photo gallery below shows the launcher emerging from the Vehicle Assembly Building, the same facility once used to stack Saturn V rockets during the Apollo Moon program. The Artemis II astronauts were also on hand for a question and answer session with reporters.

Around the clock

The first flight of astronauts on the SLS rocket and Orion spacecraft is running at least five years late. The flight’s architecture, trajectory, and goals have changed multiple times, and technical snags discovered during manufacturing and testing repeatedly shifted the schedule. The program’s engineering and budgetary problems are well documented.

But the team readying the rocket and spacecraft for launch has hit a stride in recent months. Technicians inside the Vehicle Assembly Building started stacking the SLS rocket in late 2024, beginning with the vehicle’s twin solid-fueled boosters. Then ground teams added the core stage, upper stage, and finally installed the Orion spacecraft on top of the rocket last October.

Working nearly around the clock in three shifts, it took about 12 months for crews at Kennedy to assemble the rocket and prepare it for rollout. But the launch campaign inside the VAB was remarkably smooth. Ground teams shaved about two months off the time it took to integrate the SLS rocket and Orion spacecraft for the Artemis I mission, which launched on the program’s first full-up unpiloted test flight in 2022.

“About a year ago, I was down here and we set the rollout date, and we hit it within a day or two,” said Matt Ramsey, NASA’s mission manager for Artemis II. “Being able to stay on schedule, it was a daily grind to be able to do that.”

Engineers worked through a handful of technical problems last year, including an issue with a pressure-assisted device used to assist the astronauts in opening the Orion hatch in the event of an emergency. More recently, NASA teams cleared a concern with caps installed on the rocket’s upper stage, according to Ramsey.

The most significant engineering review focused on proving the Orion heat shield is safe to fly. That assessment occurred in the background from the perspective of the technicians working on Artemis II at Kennedy.

The Artemis II team is now focused on activities at the launch pad. This week, NASA plans to perform a series of tests extending and retracting the crew access mark. Next, the Artemis II astronauts will rehearse an emergency evacuation from the launch pad. That will be followed by servicing of the rocket’s hydraulic steering system.

The big question mark

All of this leads up to the crucial practice countdown early next month. The astronauts won’t be aboard the rocket for the test, but almost everything else will look like launch day. The countdown will halt around 30 seconds prior to the simulated liftoff.

It took repeated tries to get through the Wet Dress Rehearsal for the Artemis I mission. There were four attempts at the countdown practice run before the first actual Artemis I launch countdown. After encountering hydrogen leaks on two scrubbed launch attempts, NASA performed another fueling test before finally successfully launching Artemis I in November 2022.

The launch team repaired a leaky hydrogen seal and introduced a gentler hydrogen loading procedure to overcome the problem. Hydrogen is an extremely efficient fuel for rockets, but its super-cold temperature and the tiny size of hydrogen molecules make it prone to leakage. The hydrogen feeds the SLS rocket’s four core stage engines and single upper stage engine.

“Artemis I was a test flight, and we learned a lot during that campaign getting to launch,” said Charlie Blackwell-Thompson, NASA’s Artemis II launch director. “The things that we’ve learned relative to how to go load this vehicle, how to load LOX (liquid oxygen), how to load hydrogen, have all been rolled in to the way in which we intend to load the Artemis II vehicle.”

NASA is hesitant to publicly set a target launch date until the agency gets through the dress rehearsal, but agency officials say a February launch remains feasible.

“We’ve held schedule pretty well getting to rollout today,” Isaacman said. “We have zero intention of communicating an actual launch date until we get through wet dress. But look, that’s our first window, and if everything is tracking accordingly, I know the teams are prepared, I know this crew is prepared, we’ll take it.”

“Wet dress is the driver to launch,” Blackwell-Thompson said. “With a wet dress that is without significant issues, if everything goes to plan, then certainly there are opportunities within February that could be achievable.”

One constraint that threw a wrench into NASA’s Artemis I launch campaign is no longer a significant factor for Artemis II. On Artemis I, NASA had to roll the rocket back to the Vehicle Assembly Building (VAB) after the wet dress rehearsal to complete final installation and testing on its flight termination system, which consists of a series of pyrotechnic charges designed to destroy the rocket if it flies off course and threatens populated areas after liftoff.

The US Space Force’s Eastern Range, responsible for public safety for all launches from Florida’s Space Coast, requires the flight termination system be retested after 28 to 35 days, a clock that started ticking last week before rollout. During Artemis I, technicians could not access the parts of the rocket they needed to in order to perform the retest at the launch pad. NASA now has structural arms to give ground teams the ability to reach parts higher up the rocket for the retest without returning to the hangar.

With this new capability, Artemis II could remain at the pad for launch opportunities in February and March before officials need to bring it back to the VAB to replace the flight termination system’s batteries, which still can’t be accessed at the pad.

“Putting crew on the rocket and taking the crew around the Moon, this is going be our first step toward a sustained lunar presence,” Honeycutt said. “It’s 10 days [and] four astronauts going farther from Earth than any other human has ever traveled. We’ll be validating the Orion spacecraft’s life support, navigation and crew systems in the really harsh environments of deep space, and that’s going to pave the way for future landings.”

There is still much work ahead before NASA can clear Artemis II for launch. At the launch pad, technicians will complete final checkouts and closeouts before NASA’s launch team gathers in early February for a critical practice countdown. During this countdown, called a Wet Dress Rehearsal (WDR), Blackwell-Thompson and her team will oversee the loading of the SLS rocket’s core stage and upper stage with super-cold liquid hydrogen and liquid oxygen propellants.

The cryogenic fluids, particularly liquid hydrogen, gave fits to the Artemis launch team as NASA prepared to launch the Artemis I mission—without astronauts—on the SLS rocket’s first test flight in 2022. Engineers resolved the issues and successfully launched the Artemis I mission in November 2022, and officials will apply the lessons for the Artemis II countdown.

“Artemis I was a test flight, and we learned a lot during that campaign getting to launch,” Blackwell-Thompson said. “And the things that we’ve learned relative to how to go load this vehicle, how to load LOX (liquid oxygen), how to load hydrogen, have all been rolled in to the way in which we intend to do for the Artemis II vehicle.”

Finding the right time to fly

Assuming the countdown rehearsal goes according to plan, NASA could be in a position to launch the Artemis II mission as soon as February 6. But the schedule for February 6 is tight, with no margin for error. Officials typically have about five days per month when they can launch Artemis II, when the Moon is in the right position relative to Earth, and the Orion spacecraft can follow the proper trajectory toward reentry and splashdown to limit stress on the capsule’s heat shield.

In February, the available launch dates are February 6, 7, 8, 10, and 11, with launch windows in the overnight hours in Florida. If the mission isn’t off the ground by February 11, NASA will have to stand down until a new series of launch opportunities beginning March 6. The space agency has posted a document showing all available launch dates and times through the end of April.

NASA’s leaders are eager for Artemis II to fly. NASA is not only racing China, a reality the agency’s former administrator acknowledged during the Biden administration. Now, the Trump administration is pushing NASA to accomplish a human landing on the Moon by the end of his presidential term on January 20, 2029.

One of Honeycutt’s jobs as chair of the Mission Management Team (MMT) is ensuring all the Is are dotted and Ts are crossed amid the frenzy of final launch preparations. While the hardware for Artemis II is on the move in Florida, the astronauts and flight controllers are wrapping up their final training and simulations at Johnson Space Center in Houston.

“I think I’ve got a good eye for launch fever,” he said Friday.

“As chair of the MMT, I’ve got one job, and it’s the safe return of Reid, Victor, Christina, and Jeremy. I consider that a duty and a trust, and it’s one I intend to see through.”

Artemis II, meet Astrovan II.

NASA’s first astronauts who will fly by the moon in more than 50 years participated in a practice launch countdown on Saturday, December 20, including taking their first trip on a transport vehicle steeped in almost the entire span of US space history—from Apollo through to the ongoing commercial crew program.

Artemis II commander Reid Wiseman, pilot Victor Glover, and mission specialist Christina Koch (all with NASA) and mission specialist Jeremy Hansen, an astronaut with the Canadian Space Agency, began the rehearsal at the Kennedy Space Center in Florida, proceeding as they will when they are ready to fly next year (the Artemis II launch is slated for no earlier than the first week of February and no later than April 2026).

Parked outside of their crew quarters and suit-up room was their ride to their rocket, “Astrovan II,” a modified Airstream motorhome. The almost 25-foot-long (8-meter) crew transport vehicle (CTV) was custom-wrapped with graphics depicting the moon, the Artemis II mission patch, and program insignia.

From Canoo to coach

Airstream’s Atlas Touring Coach, though, was not originally planned as NASA’s Artemis CTV. In July 2023, NASA took delivery of three fully electric vans from Canoo Technologies after the company, a startup based in Torrance, California, was awarded the contract the year before. At the time, NASA touted its selection as focusing on the “crews’ safety and comfort on the way to the [launch] pad.”

Three vans with rounded corners are parked side by side in front of a large building and an overcast sky.

Six months later, Canoo filed for bankruptcy, and NASA ceased active use of the electric vans, citing a lack of support for its mission requirements. Instead, the agency turned to another of its commercial partners, Boeing, which had its own CTV but no astronauts at present to use it.

NASA races to keep Artemis II on schedule, even when workers aren’t being paid

“The Office of Procurement has sent letters to contractors doing excepted work (including all the Artemis II contractors) indicating that work is authorized during the lapse in funding,” the official said. “Most workers have indicated a willingness to continue the work in the event of contract funding running out prior to the government reopening.”

Working on borrowed time

Several months of work remain ahead for the Artemis II team to finish testing the SLS rocket and Orion spacecraft, complete training of the astronauts and flight control teams, and then transfer the entire 322-foot-tall (98-meter) launch vehicle out to Launch Complex 39B for a fueling demonstration and launch countdown.

Thousands of workers across the country, primarily in Florida, Texas, and Alabama, are still reporting for duty to keep Artemis II’s launch date early next year. In many cases, they’re not getting their paychecks.

Even while work continues, the government shutdown is creating inefficiencies that, if left unchecked, will inevitably impact the Artemis II schedule. Just look at what’s happening with air traffic controllers across the United States as many of them are forced to take second jobs due to missed paychecks. The funding stalemate has contributed to widespread air traffic controller shortages and flight delays.

Kirk Shireman, vice president and program manager for Orion at Lockheed Martin, said Tuesday that the shutdown initially created a “nuisance” for teams working on the Artemis II mission. But it won’t be just a nuisance forever.

“I do think we’re rapidly approaching the point where it will be a significant impact, and it’s more to do with overall infrastructure,” Shireman said in response to a question from Ars at the von Braun Space Exploration Symposium in Huntsville, Alabama.

“Some of you flew here,” he said. “I suspect if you weren’t delayed coming here, you’re probably going to be delayed going home, even in the airport going through TSA. Everything that affects people’s lives is affected by the government, and when it’s shut down, it’s going to have its toll, and it’s probably going to be these secondary impacts that ultimately do it.”

Rocket Report: China tests Falcon 9 lookalike; NASA’s Moon rocket fully stacked

A South Korean rocket startup will soon make its first attempt to reach low-Earth orbit.

The Orion spacecraft for the Artemis II mission is lowered on top of the Space Launch System rocket at Kennedy Space Center, Florida.

Welcome to Edition 8.16 of the Rocket Report! The 10th anniversary of SpaceX’s first Falcon 9 rocket landing is coming up at the end of this year. We’re still waiting for a second company to bring back an orbital-class booster from space for a propulsive landing. Two companies, Jeff Bezos’ Blue Origin and China’s LandSpace, could join SpaceX’s exclusive club as soon as next month. (Bezos might claim he’s already part of the club, but there’s a distinction to be made.) Each company is in the final stages of launch preparations—Blue Origin for its second New Glenn rocket, and LandSpace for the debut flight of its Zhuque-3 rocket. Blue Origin and LandSpace will both attempt to land their first stage boosters downrange from their launch sites. They’re not exactly in a race with one another, but it will be fascinating to see how New Glenn and Zhuque-3 perform during the uphill and downhill phases of flight, and whether one or both of the new rockets stick the landing.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

The race for space-based interceptors. The Trump administration’s announcement of the Golden Dome missile defense shield has set off a race among US companies to develop and test space weapons, some of them on their own dime, Ars reports. One of these companies is a 3-year-old startup named Apex, which announced plans to test a space-based interceptor as soon as next year. Apex’s concept will utilize one of the company’s low-cost satellite platforms outfitted with an “Orbital Magazine” containing multiple interceptors, which will be supplied by an undisclosed third-party partner. The demonstration in low-Earth orbit could launch as soon as June 2026 and will test-fire two interceptors from Apex’s Project Shadow spacecraft. The prototype interceptors could pave the way for operational space-based interceptors to shoot down ballistic missiles. (submitted by biokleen)

Usual suspects … Traditional defense contractors are also getting in the game. Northrop Grumman’s CEO, Kathy Warden, said earlier this year that her company is already testing space-based interceptor components on the ground. This week, Lockheed Martin announced it is on a path to test a space-based interceptor in orbit by 2028. Neither company has discussed as much detail of their plans as Apex revealed this week.

Lockheed Martin’s latest “New Space” investment. As interest grows in rotating detonation engines for hypersonic flight, a startup specialist in the technology says it will receive backing from Lockheed Martin’s corporate venture capital arm, Aviation Week & Space Technology reports. The strategic investment by Lockheed Martin Ventures “reflects the potential of Venus’s dual-use technology” in an era of growing defense and space spending, Venus Aerospace said in a statement. Venus said its partnership with Lockheed Martin combines the former’s startup mindset with the latter’s resources and industry expertise. The companies did not announce the value of Lockheed’s investment, but Venus said it has raised $106 million since its founding in 2020. Lockheed Martin Ventures has made similar investments in other rocket startups, including Rocket Lab in 2015.

What’s this actually for? … Houston-based Venus Aerospace completed a high-thrust test flight of its Rotating Detonation Rocket Engine (RDRE) in May from Spaceport America, New Mexico. Rotating detonation engine technology is interesting because it has the potential to significantly increase fuel efficiency in various applications, from Navy carriers to rocket engines, Ars reported earlier this year. The engine works by producing a shockwave with a flow of detonation traveling through a circular channel. The engine harnesses these supersonic detonation waves to generate thrust. “Venus has proven in flight the most efficient rocket engine technology in history,” said Sassie Duggleby, co-founder and CEO of Venus Aerospace. “With support from Lockheed Martin Ventures, we will advance our capabilities to deliver at scale and deploy the engine that will power the next 50 years of defense, space, and commercial high-speed aviation.”

South Korean startup receives permission to fly. Innospace announced on October 20 that it has received South Korea’s first private commercial launch permit from the Korea AeroSpace Administration,” the Chosun Daily reports. Accordingly, Innospace will launch its independently developed “HANBIT-Nano” launch vehicle from a Brazilian launch site as early as late this month. Innospace stated that the launch window for this mission has been set for October 28 through November 28. The launch site is the Alcântara Space Center, operated by the Brazilian Air Force.

Aiming for LEO … This will be the first flight of Innospace’s HANBIT-Nano launch vehicle, standing roughly 72 feet (22 meters) tall with a diameter of 4.6 feet (1.4 meters). The two-stage rocket is powered by hybrid propulsion, consuming a mixture of paraffin and liquid oxygen. For its debut flight, the rocket will target an orbit about 300 kilometers (186 miles) high with a batch of small satellites from customers in South Korea, Brazil, and India. According to Innospace, HANBIT-Nano can lift about 200 pounds (90 kilograms) of payload into orbit.

A new record for rocket reuse. SpaceX’s launch of a Falcon 9 rocket from Florida on October 19 set a new record for reusable rockets, Ars reports. It marked the 31st launch of the company’s most-flown Falcon 9 booster. The rocket landed on SpaceX’s recovery ship in the Atlantic Ocean to be returned to Florida for a 32nd flight. Several more rockets in SpaceX’s inventory are nearing their 30th launch. In all, SpaceX has more than 20 Falcon 9 boosters in its fleet on both the East and West Coasts. SpaceX engineers are now certifying the Falcon 9 boosters for up to 40 flights apiece.

10,000 and counting … SpaceX’s two launches last weekend weren’t just noteworthy for Falcon 9 lore. Hours after setting the new booster reuse record, SpaceX deployed a batch of 28 Starlink satellites from a different rocket after lifting off from California. This mission propelled SpaceX’s Starlink program past a notable milestone. With the satellites added to the constellation on Sunday, the company has delivered more than 10,000 mass-produced Starlink spacecraft to low-Earth orbit. The exact figure stands at 10,006 satellites, according to a tabulation by Jonathan McDowell, an astrophysicist who expertly tracks comings and goings between Earth and space. About 8,700 of these Starlink satellites are still in orbit, with SpaceX adding more every week.

China is on the cusp of something big. Launch startup LandSpace is in the final stages of preparations for the first flight of its Zhuque-3 rocket and a potentially landmark mission for China, Space News reports. LandSpace said it completed the first phase of the Zhuque-3 rocket’s inaugural launch campaign this week. The Zhuque-3 is the largest commercial rocket developed to date in China, nearly matching the size and performance of SpaceX’s Falcon 9, with nine first stage engines and a single upper stage engine. One key difference is that the Zhuque-3 burns methane fuel, while Falcon 9’s engines consume kerosene. Most notably, LandSpace will attempt to land the rocket’s first stage booster at a location downrange from the launch site, similar to the way SpaceX lands Falcon 9 boosters on drone ships at sea. Zhuque-3’s first stage will aim for a land-based site in an experiment that could pave the way for LandSpace to reuse rockets in the future.

Testing status … The recent testing at Jiuquan Satellite Launch Center in northwestern China included a propellant loading demonstration and a static fire test of the rocket’s first stage engines. Earlier this week, LandSpace integrated the payload fairing on the rocket. The company said it will return the rocket to a nearby facility “for inspection and maintenance in preparation for its upcoming orbital launch and first stage recovery.” The launch is expected to happen as soon as next month.

Uprated Ariane 6 won’t launch until next year. Arianespace has confirmed that the first flight of the more powerful, four-booster variant of the Ariane 6 rocket will not be launched until 2026, European Spaceflight reports. The first Ariane 64 rocket had been expected to launch in late 2025, carrying the first batch of Amazon’s Project Kuiper satellites. On October 16, Arianespace announced the fourth and final Ariane 6 flight of the year would carry a pair of Galileo satellites for Europe’s global satellite navigation system in December. This will follow an already-scheduled Ariane 6 launch scheduled for November 4. Both of the upcoming flights will employ the same Ariane 6 configuration used on all of the rocket’s flights to date. This version, known as Ariane 62, has two strap-on solid rocket boosters.

Kuiper soon … The Ariane 64 variant will expose the rocket to stronger forces coming from four solid rocket boosters, each producing about a million pounds (4,500 kilonewtons) of thrust. ArianeGroup, the rocket’s manufacturer, said a year ago that it completed qualification of the Ariane 6 upper stage to withstand the stronger launch loads. Arianespace didn’t offer any explanation of the Ariane 64’s delay from this year to next, but it did confirm the uprated rocket will be the company’s first flight of 2026. The mission will be the first of 18 Arianespace flights dedicated to launching Amazon’s Project Kuiper broadband satellites, adding Ariane 6 to the mix of rockets deploying the Internet network in low-Earth orbit.

Duffy losing confidence in Starship. NASA acting Administrator Sean Duffy made two television appearances on Monday morning in which he shook up the space agency’s plans to return humans to the Moon, Ars reports. Speaking on Fox News, where the secretary of transportation frequently appears in his acting role as NASA chief, Duffy said SpaceX has fallen behind in developing the Starship vehicle as a lunar lander. Duffy also indirectly acknowledged that NASA’s projected target of a 2027 crewed lunar landing is no longer achievable. Accordingly, he said he intended to expand the competition to develop a lander capable of carrying humans down to the Moon from lunar orbit and back.

The rest of the story … “They’re behind schedule, and so the President wants to make sure we beat the Chinese,” Duffy said of SpaceX. “He wants to get there in his term. So I’m in the process of opening that contract up. I think we’ll see companies like Blue [Origin] get involved, and maybe others. We’re going to have a space race in regard to American companies competing to see who can actually lead us back to the Moon first.” The timing of Duffy’s public appearances on Monday seems tailored to influence a fierce, behind-the-scenes battle to hold onto the NASA leadership position. Jared Isaacman, who Trump nominated and then withdrew for the NASA posting, is again under consideration at the White House to become the agency’s next full-time administrator.

Rocket fully stacked for Artemis II. “The last major hardware component before Artemis II launches early next year has been installed,” NASA’s acting Administrator Sean Duffy posted on X Monday. Over the weekend, ground teams at Kennedy Space Center in Florida hoisted the Orion spacecraft for the Artemis II mission atop its Space Launch System rocket inside the Vehicle Assembly Building. This followed the transfer of the Orion spacecraft to the VAB from a nearby processing facility last week. With Orion installed, the rocket is fully assembled to its complete height of 322 feet (98 meters) tall.

Four months away? … NASA is still officially targeting no earlier than February 5, 2026, for the launch of the Artemis II mission. This will be the first flight of astronauts to the vicinity of the Moon since 1972, and the first glimpse of human spaceflight beyond low-Earth orbit for several generations. Upcoming milestones in the Artemis II launch campaign include a countdown demonstration inside the VAB, where the mission’s four-person crew will take their seats in the Orion spacecraft to simulate what they’ll go through on launch day.

New Glenn staged for rollout. Dave Limp, Blue Origin’s CEO, posted a video this week of the company’s second New Glenn rocket undergoing launch preparations inside a hangar at Launch Complex 36 at Cape Canaveral, Florida. The rocket’s first and second stages are now mated together and installed on the transporter erector that will carry them from the hangar to the launch pad. “We will spend the next days on final checkouts and connecting the umbilicals. Stay tuned for rollout and hotfire!” Limp wrote.

“Big step toward launch” … The connection of New Glenn’s stages and integration on the transporter erector marks a “big step toward launch,” Limp wrote. A launch sometime in November is still possible if engineers can get through a smooth test-firing of the rocket’s seven main engines on the launch pad. The rocket will send two NASA spacecraft on a journey to Mars.

China launches clandestine satellite. China launched a Long March 5 rocket Thursday with a classified military satellite heading toward geosynchronous orbit, Space News reports. The satellite is named TJS-20, and the circumstances of the launch—using China’s most powerful operational rocket—suggest TJS-20 could be the next in a line of signals intelligence-gathering missions. The previous satellite of this line, TJS-11, launched in February 2024, also on a Long March 5.

Doing a lot … This launch continued China’s increasing use of the Long March 5 and its sister variant, the Long March 5B. The Long March 5 is expendable, and although we don’t know how much it costs, it can’t be cheap. It is a complex rocket powered by 10 engines on its core stage and four boosters, some burning liquid hydrogen fuel and others burning kerosene. The second stage also has two cryogenically fueled engines. The Long March 5 has now flown 16 times in nine years and seven times within the last two years. The uptick in launches is largely due to China’s use of the Long March 5 to launch satellites for the Guowang megaconstellation.

NASA’s next Moonship reaches last stop before launch pad

The Orion spacecraft, which will fly four people around the Moon, arrived inside the cavernous Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida late Thursday night, ready to be stacked on top of its rocket for launch early next year.

The late-night transfer covered about 6 miles (10 kilometers) from one facility to another at the Florida spaceport. NASA and its contractors are continuing preparations for the Artemis II mission after the White House approved the program as an exception to work through the ongoing government shutdown, which began on October 1.

The sustained work could set up Artemis II for a launch opportunity as soon as February 5 of next year. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen will be the first humans to fly on the Orion spacecraft, a vehicle that has been in development for nearly two decades. The Artemis II crew will make history on their 10-day flight by becoming the first people to travel to the vicinity of the Moon since 1972.

Where things stand

The Orion spacecraft, developed by Lockheed Martin, has made several stops at Kennedy over the last few months since leaving its factory in May.

First, the capsule moved to a fueling facility, where technicians filled it with hydrazine and nitrogen tetroxide propellants, which will feed Orion’s main engine and maneuvering thrusters on the flight to the Moon and back. In the same facility, teams loaded high-pressure helium and ammonia coolant into Orion propulsion and thermal control systems.

The next stop was a nearby building where the Launch Abort System was installed on the Orion spacecraft. The tower-like abort system would pull the capsule away from its rocket in the event of a launch failure. Orion stands roughly 67 feet (20 meters) tall with its service module, crew module, and abort tower integrated together.

Teams at Kennedy also installed four ogive panels to serve as an aerodynamic shield over the Orion crew capsule during the first few minutes of launch.

It was then time to move Orion to the Vehicle Assembly Building (VAB), where a separate team has worked all year to stack the elements of NASA’s Space Launch System rocket. In the coming days, cranes will lift the spacecraft, weighing 78,000 pounds (35 metric tons), dozens of stories above the VAB’s center aisle, then up and over the transom into the building’s northeast high bay to be lowered atop the SLS heavy-lift rocket.

No one will be able to sleep when the launch window opens, however.

Wiseman: About seven seconds prior to liftoff, the four main engines light, and they come up to full power. And then the solids light, and that’s when you’re going. What’s crazy to me is that it’s six and a half seconds into flight before the solids clear the top of the tower. Five million pounds of machinery going straight uphill. Six and a half seconds to clear the tower. As a human, I can’t wait to feel that force.

A little more than two minutes into flight, the powerful side-mounted boosters will separate. They will have done the vast majority of lifting to that point, with the rocket already reaching a velocity of 3,100 mph (5,000 kph) and an altitude of 30 miles (48 km), well on its way to space. As payload specialists, Koch and Hansen will largely be along for the ride. Wiseman, the commander, and Glover, the pilot, will be tracking the launch, although the rocket’s flight will be fully automated unless something goes wrong.

Wiseman: Victor and I, we have a lot of work. We have a lot of systems to monitor. Hopefully, everything goes great, and if it doesn’t, we’re very well-trained on what to do next.

After 8 minutes and 3 seconds, the rocket’s core stage will shut down, and the upper stage and Orion spacecraft will separate about 10 seconds later. They will be in space, with about 40 minutes to prepare for their next major maneuver.

In orbit

Koch: The wildest thing in this mission is that literally, right after main-engine cutoff, the first thing Jeremy and I do is get up and start working. I don’t know of a single other mission, certainly not in my memory, where that has been the case in terms of physical movement in the vehicle, setting things up.

Koch, Wiseman, and Glover have all flown to space before, either on a SpaceX Dragon or Russian Soyuz vehicle, and spent several months on the International Space Station. So they know how their bodies will react to weightlessness. Nearly half of all astronauts experience “space adaptation syndrome” during their first flight to orbit, and there is really no way to predict who it will afflict beforehand. This is a real concern for Hansen, a first-time flier, who is expected to hop out of his seat and start working.

Hansen: I’m definitely worried about that, just from a space motion sickness point of view. So I’ll just be really intentional. I won’t move my head around a lot. Obviously, I’m gonna have to get up and move. And I’ll just be very intentional in those first few hours while I’m moving around. And the other thing that I’ll do—it’s very different from Space Station—is I just have everything memorized, so I don’t have to read the procedure on those first few things. So I’m not constantly going down to the [tablet] and reading, and then up. And I’ll just try to minimize what I do.

Koch and Hansen will set up and test essential life support systems on the spacecraft because if the bathroom does not work, they’re not going to the Moon.

Hansen: We kind of split the vehicle by side. So Christina is on the side of the toilet. She’s taking care of all that stuff. I’m on the side of the water dispenser, which is something they want to know: Can we dispense water? It’s not a very complicated system. We just got to get up, get the stuff out of storage, hook it up. I’ll have some camera equipment that I’ll pull out of there. I’ve got the masks we use if we have a fire and we’re trying to purge the smoke. I’ve got to get those set up and make sure they’re good to go. So it’s just little jobs, little odds and ends.

Unlike a conventional rocket mission, Artemis II vehicle’s upper stage, known as the Interim Cryogenic Propulsion Stage, will not fire right away. Rather, after separating from the core stage, Orion will be in an elliptical orbit that will take it out to an apogee of 1,200 nautical miles, nearly five times higher than the International Space Station. There, the crew will be further from Earth than anyone since the Apollo program.

Welcome to Edition 8.12 of the Rocket Report! We often hear from satellite operators—from the military to venture-backed startups—about their appetite for more launch capacity. With so many rocket launches happening around the world, some might want to dismiss these statements as a corporate plea for more competition, and therefore lower prices. SpaceX is on pace to launch more than 150 times this year. China could end the year with more than 70 orbital launches. These are staggering numbers compared to global launch rates just a few years ago. But I’m convinced there’s room for more alternatives for reliable (and reusable) rockets. All of the world’s planned mega-constellations will need immense launch capacity just to get off the ground, and if successful, they’ll go into regular replacement and replenishment cycles. Throw in the still-undefined Golden Dome missile shield and many nations’ desire for a sovereign launch capability, and it’s easy to see the demand curve going up.

Sharp words from Astra’s Chris Kemp. Chris Kemp, the chief executive officer of Astra, apparently didn’t get the memo about playing nice with his competitors in the launch business. Kemp made some spicy remarks at the Berkeley Space Symposium 2025 earlier this month, billed as the largest undergraduate aerospace event at the university (see video of the talk). During the speech, Kemp periodically deviated from building up Astra to hurling insults at several of his competitors in the launch industry, Ars reports. To be fair to Kemp, some of his criticisms are not without a kernel of truth. But they are uncharacteristically rough all the same, especially given Astra’s uneven-at-best launch record and financial solvency to date.

Wait, what?! … Kemp is generally laudatory in his comments about SpaceX, but his most crass statement took aim at the quality of life of SpaceX employees at Starbase, Texas. He said life at Astra is “more fun than SpaceX because we’re not on the border of Mexico where they’ll chop your head off if you accidentally take a left turn.” For the record, no SpaceX employees have been beheaded. “And you don’t have to live in a trailer. And we don’t make you work six and a half days a week, 12 hours a day.” Kemp also accused Firefly Aerospace of sending Astra “garbage” rocket engines as part of the companies’ partnership on propulsion for Astra’s next-generation rocket.

A step forward for Europe’s reusable rocket program. No one could accuse the European Space Agency and its various contractors of moving swiftly when it comes to the development of reusable rockets. However, it appears that Europe is finally making some credible progress, Ars reports. Last week, the France-based ArianeGroup aerospace company announced that it completed the integration of the Themis vehicle, a prototype rocket that will test various landing technologies, on a launch pad in Sweden. Low-altitude hop tests, a precursor for developing a rocket’s first stage that can vertically land after an orbital launch, could start late this year or early next.

Hopping into the future … “This milestone marks the beginning of the ‘combined tests,’ during which the interface between Themis and the launch pad’s mechanical, electrical, and fluid systems will be thoroughly trialed, with the aim of completing a test under cryogenic conditions,” ArianeGroup said. This particular rocket will likely undergo only short hops, initially about 100 meters. A follow-up vehicle, Themis T1E, is intended to fly medium-altitude tests at a later date. Some of the learnings from these prototypes will feed into a smaller, reusable rocket intended to lift 500 kilograms to low-Earth orbit. This is under development by MaiaSpace, a subsidiary of ArianeGroup. Eventually, the European Space Agency would like to use technology developed as part of Themis to develop a new line of reusable rockets that will succeed the Ariane 6 rocket.

Navy conducts Trident missile drills. The US Navy carried out four scheduled missile tests of a nuclear-capable weapons system off the coast of Florida within the last week, Defense News reports. The service’s Strategic Systems Programs conducted flights of unarmed Trident II D5 Life Extension missiles from a submerged Ohio-class ballistic missile submarine from September 17 to September 21 as part of an ongoing scheduled event meant to test the reliability of the system. “The missile tests were not conducted in response to any ongoing world events,” a Navy release said.

Secret with high visibility … The Navy periodically performs these Trident missile tests off the coasts of Florida and California, taking advantage of support infrastructure and range support from the two busiest US spaceports. The military doesn’t announce the exact timing of the tests, but warnings issued for pilots to stay out of the area give a general idea of when they might occur. One of the launch events Sunday was visible from Puerto Rico, illuminating the night sky in photos published on social media. The missiles fell in the Atlantic Ocean as intended, the Navy said. The Trident II D5 missiles were developed in the 1980s and are expected to remain in service on the Navy’s ballistic missile submarines into the 2040s. The Trident system is one leg of the US military’s nuclear triad, alongside land-based Minuteman ballistic missiles and nuclear-capable strategic bombers. (submitted by EllPeaTea)

Firefly plans for Alpha’s return to flight. Firefly Aerospace expects to resume Alpha launches in the “coming weeks,” with two flights planned before the end of the year, Space News reports. These will be the first flights of Firefly’s one-ton-class Alpha rocket since a failure in April destroyed a Lockheed Martin tech demo satellite after liftoff from California. In a quarterly earnings call, Firefly shared a photo showing its next two Alpha rockets awaiting shipment from the company’s Texas factory.

Righting the ship … These next two launches really need to go well for Firefly. The Alpha rocket has, at best, a mixed record with only two fully successful flights in six attempts. Two other missions put their payloads into off-target orbits, and two Alpha launches failed to reach orbit at all. Firefly went public on the NASDAQ stock exchange last month, raising nearly $900 million in the initial public offering to help fund the company’s future programs, namely the medium-lift Eclipse rocket developed in partnership with Northrop Grumman. There’s a lot to like about Firefly. The company achieved the first fully successful landing of a commercial spacecraft on the Moon in March. NASA has selected Firefly for three more commercial landings on the Moon, and Firefly reported this week it has an agreement with an unnamed commercial customer for an additional dedicated mission. But the Alpha program hasn’t had the same level of success. We’ll see if Firefly can get the rocket on track soon. (submitted by EllPeaTea)

Avio wins contract to launch “extra-European” mission. Italian rocket builder Avio has signed a launch services agreement with US-based launch aggregator SpaceLaunch for a Vega C launch carrying an Earth observation satellite for an “extra-European institutional customer” in 2027, European Spaceflight reports. Avio announced that it had secured the launch contract on September 18. According to the company, the contract was awarded through an open international competition, with Vega C chosen for its “versatility and cost-effectiveness.” While Avio did not reveal the identity of the “extra-European” customer, it said that it would do so later this year.

Plenty of peculiarities … There are several questions to unpack here, and Andrew Parsonson of European Spaceflight goes through them all. Presumably, extra-European means the customer is based outside of Europe. Avio’s statement suggests we’ll find out the answer to that question soon. Details about the US-based launch broker SpaceLaunch are harder to find. SpaceLaunch appears to have been founded in January 2025 by two former Firefly Aerospace employees with a combined 40 years of experience in the industry. On its website, the company claims to provide end-to-end satellite launch integration, mission management, and launch procurement services with a “portfolio of launch vehicle capacity around the globe.” SpaceLaunch boasts it has supported the launch of more than 150 satellites on 12 different launch vehicles. However, according to public records, it does not appear that the company itself has supported a single launch. Instead, the claim seems to credit SpaceLaunch with launches that were actually carried out during the two founders’ previous tenures at Spaceflight, Firefly Aerospace, Northrop Grumman, and the US Air Force.

Falcon 9 launches three missions for NASA and NOAA. Scientists loaded three missions worth nearly $1.6 billion on a SpaceX Falcon 9 rocket for launch Wednesday, toward an orbit nearly a million miles from Earth, to measure the supersonic stream of charged particles emanating from the Sun, Ars reports. One of the missions, from the National Oceanic and Atmospheric Administration (NOAA), will beam back real-time observations of the solar wind to provide advance warning of geomagnetic storms that could affect power grids, radio communications, GPS navigation, air travel, and satellite operations. The other two missions come from NASA, with research objectives that include studying the boundary between the Solar System and interstellar space and observing the rarely seen outermost layer of our own planet’s atmosphere.

Immense value …All three spacecraft will operate in orbit around the L1 Lagrange point, a gravitational balance point located more than 900,000 miles (1.5 million kilometers) from Earth. Bundling these three missions onto the same rocket saved at least tens of millions of dollars in launch costs. Normally, they would have needed three different rockets. Rideshare missions to low-Earth orbit are becoming more common, but spacecraft departing for more distant destinations like the L1 Lagrange point are rare. Getting all three missions on the same launch required extensive planning, a stroke of luck, and fortuitous timing. “This is the ultimate cosmic carpool,” said Joe Westlake, director of NASA’s heliophysics division. “These three missions heading out to the Sun-Earth L1 point riding along together provide immense value for the American taxpayer.”

US officials concerned about China mastering reusable launch. SpaceX’s dominance in reusable rocketry is one of the most important advantages the United States has over China as competition between the two nations extends into space, US Space Force officials said Monday. But several Chinese companies are getting close to fielding their own reusable rockets, Ars reports. “It’s concerning how fast they’re going,” said Brig. Gen. Brian Sidari, the Space Force’s deputy chief of space operations for intelligence. “I’m concerned about when the Chinese figure out how to do reusable lift that allows them to put more capability on orbit at a quicker cadence than currently exists.”

By the numbers … China has used 14 different types of rockets on its 56 orbital-class missions this year, and none have flown more than 11 times. Eight US rocket types have cumulatively flown 145 times, with 122 of those using SpaceX’s workhorse Falcon 9. Without a reusable rocket, China must maintain more rocket companies to sustain a launch rate of just one-third to one-half that of the United States. This contrasts with the situation just four years ago, when China outpaced the United States in orbital rocket launches. The growth in US launches has been a direct result of SpaceX’s improvements to launch at a higher rate, an achievement primarily driven by the recovery and reuse of Falcon 9 boosters and payload fairings.

Atlas V launches more Kuiper satellites. Roughly an hour past sunrise Thursday, an Atlas V rocket from United Launch Alliance took flight from Cape Canaveral Space Force Station, Florida. Onboard the rocket, flying in its most powerful configuration, were the next 27 Project Kuiper broadband satellites from Amazon, Spaceflight Now reports. This is the third batch of production satellites launched by ULA and the fifth overall for the growing low-Earth orbit constellation. The Atlas V rocket released the 27 Kuiper satellites about 280 miles (450 kilometers) above Earth. The satellites will use onboard propulsion to boost themselves to their assigned orbit at 392 miles (630 kilometers).

Another Kuiper launch on tap … With this deployment, Amazon now has 129 satellites in orbit. This is a small fraction of the network’s planned total of 3,232 satellites, but Amazon has enjoyed a steep ramp-up in the Kuiper launch cadence as the company’s satellite assembly line in Kirkland, Washington, continues churning out spacecraft. Another 24 Kuiper satellites are slated to launch September 30 on a SpaceX Falcon 9 rocket, and Amazon has delivered enough satellites to Florida for an additional launch later this fall.

German military will fly with Ariane 6. Airbus Defense and Space has awarded Arianespace a contract to launch a pair of SATCOMBw-3 communications satellites for the German Armed Forces, European Spaceflight reports. Airbus is the prime contractor for the nearly $2.5 billion (2.1 billion euro) SATCOMBw-3 program, which will take over from the two-satellite SATCOMBw-2 constellation currently providing secure communications for the German military. Arianespace announced Wednesday that it had been awarded the contract to launch the satellites aboard two Ariane 6 rockets. “By signing this new strategic contract for the German Armed Forces, Arianespace accomplishes its core mission of guaranteeing autonomous access to space for European sovereign satellites,” said Arianespace CEO David Cavaillolès.

Running home to Europe … The chief goal of the Ariane 6 program is to provide Europe with independent access to space, something many European governments see as a strategic requirement. Several European military, national security, and scientific satellites have launched on SpaceX Falcon 9 rockets in the last few years as officials waited for the debut of the Ariane 6 rocket. With three successful Ariane 6 flights now in the books, European customers seem to now have the confidence to commit to flying their satellites on Ariane 6. (submitted by EllPeaTea)

Artemis II launch targeted for February. NASA is pressing ahead with preparations for the first launch of humans beyond low-Earth orbit in more than five decades, and officials said Tuesday that the Artemis II mission could take flight early next year, Ars reports. Although work remains to be done, the space agency is now pushing toward a launch window that opens on February 5, 2026, officials said during a news conference on Tuesday at Johnson Space Center. The Artemis II mission represents a major step forward for NASA and seeks to send four astronauts—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—around the Moon and back. The 10-day mission will be the first time astronauts have left low-Earth orbit since the Apollo 17 mission in December 1972.

Orion named Integrity … The first astronauts set to fly to the Moon in more than 50 years will do so in Integrity, Ars reports. NASA’s Artemis II crew revealed Integrity as the name of their Orion spacecraft during a news conference on Wednesday at the Johnson Space Center in Houston. “We thought, as a crew, we need to name this spacecraft. We need to have a name for the Orion spacecraft that we’re going to ride this magical mission on,” said Wiseman, commander of the Artemis II mission.

FAA reveals new Starship trajectories. Sometime soon, perhaps next year, SpaceX will attempt to fly one of its enormous Starship rockets from low-Earth orbit back to its launch pad in South Texas. A successful return and catch at the launch tower would demonstrate a key capability underpinning Elon Musk’s hopes for a fully reusable rocket. In order for this to happen, SpaceX must overcome the tyranny of geography. A new document released by the Federal Aviation Administration shows the narrow corridors Starship will fly to space and back when SpaceX tries to recover them, Ars reports.

Flying over people … It was always evident that flying a Starship from low-Earth orbit back to Starbase would require the rocket to fly over Mexico and portions of South Texas. The rocket launches to the east over the Gulf of Mexico, so it must approach Starbase from the west when it comes in for a landing. The new maps show SpaceX will launch Starships to the southeast over the Gulf and the Caribbean Sea, and directly over Jamaica, or to the northeast over the Gulf and the Florida peninsula. On reentry, the ship will fly over Baja California and Mexico’s interior near the cities of Hermosillo and Chihuahua, each with a population of roughly a million people. The trajectory would bring Starship well north of the Monterrey metro area and its 5.3 million residents, then over the Rio Grande Valley near the Texas cities of McAllen and Brownsville.

New Glenn’s second flight at least a month away. The second launch of Blue Origin’s New Glenn rocket, carrying a NASA smallsat mission to Mars, is now expected in late October or early November, Space News reports. Tim Dunn, NASA’s senior launch director at Kennedy Space Center, provided an updated schedule for the second flight of New Glenn in comments after a NASA-sponsored launch on a Falcon 9 rocket Wednesday. Previously, the official schedule from NASA showed the launch date as no earlier than September 29.

No surprise … It was already apparent that this launch wouldn’t happen September 29. Blue Origin has test-fired the second stage for the upcoming flight of the New Glenn rocket but hasn’t rolled the first stage to the launch pad for its static fire. Seeing the rocket emerge from Blue’s factory in Florida will be an indication that the launch date is finally near. Blue Origin will launch NASA’s ESCAPADE mission, a pair of small satellites to study how the solar wind interacts with the Martian upper atmosphere.

Blue Origin will launch a NASA rover to the Moon. NASA has awarded Blue Origin a task order worth up to $190 million to deliver its Volatiles Investigating Polar Exploration Rover (VIPER) to the Moon’s surface, Aviation Week & Space Technology reports. Blue Origin, one of 13 currently active Commercial Lunar Payload Services (CLPS) providers, submitted the only bid to carry VIPER to the Moon after NASA requested offers from industry last month. NASA canceled the VIPER mission last year, citing cost overruns with the rover and delays in its planned ride to the Moon aboard a lander provided by Astrobotic. But engineers had already completed assembly of the rover, and scientists protested NASA’s decision to terminate the mission.

Some caveats … Blue Origin will deliver VIPER to a location near the Moon’s south pole in late 2027 using a robotic Blue Moon MK1 lander, a massive craft larger than the Apollo lunar landing module. The company’s first Blue Moon MK1 lander is scheduled to fly to the Moon next year. NASA’s contract for the VIPER delivery calls for Blue Origin to design accommodations for the rover on the Blue Moon lander. The agency said it will decide whether to proceed with the actual launch on a New Glenn rocket and delivery of VIPER to the Moon based partially on the outcome of the first Blue Moon test flight next year.

Whole and undivided

Ultimately, Integrity was inspired by something one of their instructors said while on a team-building trip to Iceland.

“He coined this for us, and we held on to it,” said Hansen, who, unlike his NASA crewmates, is a Canadian Space Agency astronaut. “It was this idea that you’re not a person who has integrity, you’re a person who strives to be in integrity. Sometimes you’re out of integrity, and sometimes you’re in your integrity. That was profound for all of us.”

For Glover, it boiled down to the definition.

“The Latin root means ‘whole.’ It’s a very simple concept, and it’s about being whole. This crew comes together as pieces—the four of us and our backups—but the six of us make up a whole team. The vehicle, the pieces come together and make up a whole spacecraft,” he said.

“What people anecdotally say is that integrity is what you do when no one’s watching. That, and truth, honor, and integrity matter,” said Glover. “There are so many layers to that name and what it means and what it inspires.”

Integrating Integrity

Integrity is one of the tenets of the Astronaut Code of Professional Responsibility. It is also one of the Canadian Space Agency’s core values.

“We all strive to be in integrity all of the time, but integrity isn’t an absolute that you either have or don’t have,” said Koch. “So this helps us give grace and build trust with each other.”

“I hope that people hearing [the name] over the 10 days of the mission appreciate all of the different things that it means, from a whole ship, a whole crew, to a wholeness and wellness that I think humanity just needs. We need to hear more of that togetherness and wholeness,” said Glover.

Now that it has been announced, next up is for Integrity to be used as the crew’s possible call sign.

“We waited to make sure the whole enterprise was ready for us to announce it before we even used it,” said Glover. “I think we’ll start using it in sims: ‘Houston, Integrity. Integrity, Houston.’ That’s the plan.

“But if someone doesn’t like that, then we won’t, and we can say Orion,” he said.

NASA targeting early February for Artemis II mission to the Moon

artemis II, NASA, sls rocket, Space / /

NASA is pressing ahead with preparations for the first launch of humans beyond low-Earth orbit in more than five decades, and officials said Tuesday that the Artemis II mission could take flight early next year.

Although work remains to be done, the space agency is now pushing toward a launch window that opens on February 5, 2026, officials said during a news conference on Tuesday at Johnson Space Center.

The Artemis II mission represents a major step forward for NASA and seeks to send four astronauts—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—around the Moon and back. The 10-day mission will be the first time astronauts have left low-Earth orbit since the Apollo 17 mission in December 1972.

Hardware nearing readiness

The mission’s Space Launch System rocket has been stacked and declared ready for flight. The Orion spacecraft is in the final stages of preparation and will be attached to the top of the rocket later this year.

Early next year, the combined stack will roll out to the vehicle’s launch site at Kennedy Space Center, said Charlie Blackwell-Thompson, Artemis launch director. At the pad, the rocket and spacecraft will be connected to ground systems, and after about two weeks, it will undergo a “wet dress rehearsal.”

During this fueling test, the first and second stages of the rocket will be fully loaded with liquid hydrogen and oxygen, and the countdown will be taken down to T-29 seconds. After this test, the rocket will be de-tanked and turned around for launch.

Due to the orbits of Earth and the Moon and various constraints on the mission, there are launch windows each month that last four to eight days. In February, that window opens on the fifth, and it would be an evening launch, Blackwell-Thompson said.

After launching, the Orion spacecraft will separate from the upper stage of the SLS rocket a little more than three hours after liftoff. It will spend about 24 hours in orbit around Earth, during which time the four astronauts on board will perform various checkouts to ensure the vehicle’s life support systems, thrusters, and other equipment are performing nominally.

All the news that’s fit to lift

“There’s a lot of interest because of the fear that there’s just not a lot of capacity.”

Welcome to Edition 8.11 of the Rocket Report! We have reached the time of year when it is possible the US government will shut down its operations at the end of this month, depending on congressional action. A shutdown would have significant implications for many NASA missions, but most notably a couple of dozen in the science directorate that the White House would like to shut down. At Ars, we will be watching this issue closely in the coming days. As for Artemis II, it seems to be far enough along that a launch next February seems possible as long as any government closure does not drag on for weeks and weeks.

As always, we welcome reader submissions, and if you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Rocket Lab to sell common shares. The space company said Tuesday that it intends to raise up to $750 million by selling common shares, MSN reports. This new at-the-market program replaces a prior agreement that allowed Rocket Lab to sell up to $500 million of stock. Under that earlier arrangement, the company had sold roughly $396.6 million in shares before ending the program.

Seeking to scale up … The program’s structure enables Rocket Lab to sell shares periodically through the appointed agents, who may act as either principals or intermediaries. The larger offering indicates that Rocket Lab is aiming to bolster its cash reserves to support ongoing development of its launch services, including the medium-lift Neutron rocket and spacecraft manufacturing operations. The company’s stock dropped by about 10 percent after the announcement.

Astra targets mid-2026 for Rocket 4 debut. Astra is targeting next summer for the first flight of its Rocket 4 vehicle as the company prepares to reenter the launch market, Space News reports. At the World Space Business Week conference in Paris, Chris Kemp, chief executive of Astra, said the company was on track for a first launch of Rocket 4 in summer 2026 from Cape Canaveral, Florida. He highlighted progress Astra is making, such as tests of a new engine the company developed for the vehicle’s first stage that produces 42,000 pounds of thrust. Two of those engines will power the first stage, while the upper stage will use a single Hadley engine produced by Ursa Major.

Pricing a launch competitively … The vehicle will initially be capable of placing about 750 kilograms into low-Earth orbit for a price of $5 million. “That’ll be very competitive,” Kemp said in an interview after the presentation, similar to what SpaceX charges for payloads of that size through its rideshare program. The company is targeting customers seeking alternatives to SpaceX in a constrained launch market. “There’s a lot of interest because of the fear that there’s just not a lot of capacity,” he said, particularly for satellites too large to launch on Rocket Lab’s Electron.

Avio seeks to raise 400 million euros. Italian rocket builder Avio’s board of directors has approved a 400 million euro ($471 million) capital increase to fund an expansion of its manufacturing capacity to meet rising demand in the global space and defense markets, European Spaceflight reports. The company expects to complete the capital increase by the end of the year; however, it is still subject to a shareholder vote, scheduled for October 23.

Small rockets, big plans … The capital raise is part of a new 10-year business plan targeting an average annual growth rate of about 10 percent in turnover and more than 15 percent in core profit. This growth is projected to be driven by a higher Vega C launch cadence, the introduction of the Vega E rocket, continued participation in the Ariane 6 program by providing solid rocket boosters, and the construction of a new defense production facility in the United States, which is expected to be completed by 2028.

Isar working toward second Spectrum launch. In a briefing this week, Isar Aerospace executives discussed the outcome of the investigation into the March 30 launch of the Spectrum rocket from the Andøya Spaceport in northern Norway, Space News reports. The vehicle activated its flight termination system about half a minute after liftoff, shutting down its engines and plummeting into the waters just offshore of the pad. The primary issue with the rocket was a loss of attitude control.

Bend it like Spectrum … Alexandre Dalloneau, vice president of mission and launch operations at Isar, said that the company had not properly characterized bending modes of the vehicle at liftoff. Despite the failure to get to orbit, Dalloneau considers the first Spectrum launch a successful test flight. The company is working toward a second flight of Spectrum, which will take place “as soon as possible,” Dalloneau said. He did not give a specific target launch date, but officials indicated they were hoping to launch near the end of this year or early next year. (submitted by EllPeaTea)

Callisto rocket test delayed again. A new document from the French space agency CNES has revealed that the inaugural flight of the Callisto reusable rocket demonstrator has slipped from 2026 to 2027, European Spaceflight reports. This reusable launch testbed is a decade old. Conceived in 2015, the Cooperative Action Leading to Launcher Innovation in Stage Toss-back Operations (Callisto) project is a collaboration between CNES and the German and Japanese space agencies aimed at maturing reusable rocket technology for future European and Japanese launch systems.

Still waiting … The Callisto demonstrator will stand 14 meters tall, with a width of 1.1 meters and a takeoff mass of 3,500 kilograms. This latest revision to the program’s timeline comes less than a year after JAXA confirmed in October 2024 that the program’s flight-test campaign had been pushed to 2026. The campaign will be carried out from the Guiana Space Centre in French Guiana and will include an integration phase followed by eight test flights and two demonstration flights, all to be completed over a period of eight months.

Falcon 9 launches larger Cygnus spacecraft. The first flight of Northrop’s upgraded Cygnus spacecraft, called Cygnus XL, launched Sunday evening from Cape Canaveral Space Force Station, Florida, en route to the International Space Station, Ars reports. Without a rocket of its own, Northrop Grumman inked a contract with SpaceX for three Falcon 9 launches to carry the resupply missions until engineers could develop a new, all-domestic version of the Antares rocket. Sunday’s launch was the last of these three Falcon 9 flights. Northrop is partnering with Firefly Aerospace on a new rocket, the Antares 330, using a new US-made booster stage and engines.

A few teething issues … This new rocket won’t be ready to fly until late 2026, at the earliest, somewhat later than Northrop officials originally hoped. The company confirmed it has purchased a fourth Falcon 9 launch from SpaceX for the next Cygnus cargo mission in the first half of next year, in a bid to bridge the gap until the debut of the Antares 330 rocket. Due to problems with the propulsion system on the larger Cygnus vehicle, its arrival at the space station was delayed. But the vehicle successfully reached the station on Thursday, carrying a record 11,000 pounds of cargo.

Launch companies still struggling with cadence. Launch companies are reiterating plans to sharply increase flight rates to meet growing government and commercial demand, even as some fall short of earlier projections, Space News reports. Executives speaking at a September 15 panel at the World Space Business Week conference highlighted efforts to scale up flights of new vehicles that have entered service in the last two years. “The key for us is cadence,” said Laura Maginnis, vice president of New Glenn mission management at Blue Origin. However, the publication notes, at this time last year, Blue Origin was projecting eight to 10 New Glenn launches this year. There has been one.

It’s difficult to go from 1 to 100 … Blue Origin is not alone in falling short of forecasts. United Launch Alliance projected 20 launches in 2025 between the Atlas 5 and Vulcan Centaur, but in August, CEO Tory Bruno said the company now expects nine. As recently as June, Arianespace projected five Ariane 6 launches this year, including the debut of the more powerful Ariane 64, with four solid-rocket boosters, but has completed only two Ariane 62 flights, including one in August.

NASA makes some modifications to SLS for Artemis II. This week, the space agency declared the SLS rocket is now “ready” to fly crew for the Artemis II mission early next year. However, NASA and its contractors did make some modest changes after the first flight of the booster in late 2022. For example, the Artemis II rocket includes an improved navigation system compared to Artemis I. Its communications capability has also been improved by repositioning antennas on the rocket to ensure continuous communications with the ground.

Not good, but bad vibrations … Additionally, SLS will jettison the spent boosters four seconds earlier during the Artemis II ascent than occurred during Artemis I. Dropping the boosters several seconds closer to the end of their burn will give engineers flight data to correlate with projections that shedding the boosters several seconds sooner will yield approximately 1,600 pounds of payload to Earth orbit for future SLS flights. During the Artemis I test flight, the SLS rocket experienced higher-than-expected vibrations near the solid rocket booster attachment points that were caused by unsteady airflow. To steady the airflow, a pair of 6-foot-long strakes flank each booster’s forward connection points on the SLS intertank.

Federal judge sides with SpaceX, FAA. The initial launch of Starship in April 2023 spread debris across a wide area, sending pulverized concrete as far as six miles away as the vehicle tore up the launch pad. After this, environmental groups and other organizations sued the FAA when the federal organization reviewed the environmental impact of this launch and cleared SpaceX to launch again several months later. A federal judge in Washington, DC, ruled this week that the FAA did not violate environmental laws as part of this review, the San Antonio Express-News reports.

Decision grounded within reason … In his opinion issued Monday, Judge Carl Nichols determined the process was not capricious, writing, “Most of the (programmatic environmental assessment’s) conclusions were well-reasoned and supported by the record, and while parts of its analysis left something to be desired, even those parts fell ‘within a broad zone of reasonableness.'” The environmental organizations said they were considering the next steps for the case and a potential appeal.

Welcome to Edition 8.06 of the Rocket Report! Two of the world’s most storied rocket builders not named SpaceX achieved major successes this week. Arianespace’s Ariane 6 rocket launched from French Guiana on its third flight Tuesday night with a European weather satellite. Less than 20 minutes later, United Launch Alliance’s third Vulcan rocket lifted off from Florida on a US military mission. These are two of the three big rockets developed in the Western world that have made their orbital debuts in the last two years, alongside Blue Origin’s New Glenn launcher. Ariane 6 narrowly won the “race” to reach its third orbital flight, but if you look at it another way, Ariane 6 reached its third flight milestone 13 months after its inaugural launch. It took Vulcan more than 19 months, and New Glenn has flown just once. SpaceX’s Super Heavy/Starship rocket has flown nine times but has yet to reach orbit.

Sixth success for sea-launched Chinese rocket. Private Chinese satellite operator Geespace added 11 spacecraft to its expanding Internet of Things constellation on August 8, aiming to boost low-power connectivity in key emerging markets, Space News reports. The 11 satellites rode into orbit aboard a solid-fueled Jielong 3 (Smart Dragon 3) rocket lifting off from an ocean platform in the Yellow Sea off the coast of Rizhao, a city in eastern China’s Shandong province. This was the sixth flight of the Jielong 3, a rocket developed by a commercially oriented spinoff of the state-owned China Academy of Launch Vehicle Technology.

Mistaken for a meteor … The fourth stage of the Jielong 3 rocket, left in orbit after deploying its 11 satellite payloads, reentered the atmosphere late Sunday night. The fiery and destructive reentry created a fireball that streaked across the skies over Spain, the Spanish newspaper El Mundo reports. Many Spanish residents identified the streaking object as a meteor associated with the Perseid meteor shower. But it turned out to be a piece of China’s Jielong 3 rocket. Any debris that may have survived the scorching reentry likely fell into the Mediterranean Sea.

Portugal green-lights Azores spaceport. The Portuguese government has granted the Atlantic Spaceport Consortium a license to build and operate a rocket launch facility on the island of Santa Maria in the Azores, European Spaceflight reports. The Atlantic Spaceport Consortium (ASC) was founded in 2019 with the goal of developing a commercial spaceport on Santa Maria, 1,500 kilometers off the Portuguese mainland. In September 2024, the company showcased the island’s suitability as a launch site by launching two small solid-fuel amateur-class rockets that it developed in-house.

What’s on deck? … The spaceport license granted by Portugal’s regulatory authorities does not cover individual launches themselves. Those must be approved in a separate licensing process. It’s likely that the launch site on Santa Maria Island will initially host suborbital launches, including flights by the Polish rocket company SpaceForest. The European Space Agency has also selected Santa Maria as the landing site for the first flight of the Space Rider lifting body vehicle after it launches into orbit, perhaps in 2027.

Why is Jeff Bezos buying launches from Elon Musk? Early Monday morning, a Falcon 9 rocket lifted off from its original launch site in Florida. Remarkably, it was SpaceX’s 100th launch of the year. Perhaps even more notable was the rocket’s payload: two-dozen Project Kuiper satellites, which were dispensed into low-Earth orbit on target, Ars reports. This was SpaceX’s second launch of satellites for Amazon, which is developing a constellation to deliver low-latency broadband Internet around the world. SpaceX, then, just launched a direct competitor to its Starlink network into orbit. And it was for the founder of Amazon, Jeff Bezos, who owns a rocket company of his own in Blue Origin.

Several answers … So how did it come to this—Bezos and Elon Musk, competitors in so many ways, working together in space? There are several answers. Most obviously, launching payloads for customers is one of SpaceX’s two core business areas, alongside Starlink. SpaceX sells launch services to all comers and typically offers the lowest price per kilogram to orbit. There’s immediate revenue to be made if a company with deep pockets like Amazon is willing to pay SpaceX. Second, the other options to get Kuiper satellites into orbit just aren’t available at the volume Amazon needs. Amazon has reserved the lion’s share of its Kuiper launches with SpaceX’s competitors: United Launch Alliance, Arianespace, and Jeff Bezos’ own space company Blue Origin. Lastly, SpaceX could gain some leverage by providing launch services to Amazon. In return for a launch, SpaceX has asked other companies with telecom satellites, such as OneWeb and Kepler Communications, to share spectrum rights to enable Starlink to expand into new markets.

Trump orders cull of commercial launch regulations. President Donald Trump signed an executive order on Wednesday directing government agencies to “eliminate or expedite” environmental reviews for commercial launch and reentry licenses, Ars reports. The FAA, part of the Department of Transportation, is responsible for granting the licenses after ensuring launch and reentries don’t endanger the public, comply with environmental laws, and comport with US national interests. The drive toward deregulation will be welcome news for companies like SpaceX, led by onetime Trump ally Elon Musk; SpaceX conducts nearly all of the commercial launches and reentries licensed by the FAA.

Deflecting scrutiny? … The executive order does several things, and not all of them will be as controversial as the potential elimination of environmental reviews. The order includes a clause directing the government to reevaluate, amend, or rescind a slate of launch-safety regulations written during the first Trump administration. The FAA published the new regulations, known as Part 450, in 2020, and they went into effect in 2021, but space companies have complained that they are too cumbersome and have slowed down the license approval process. The Biden administration established a committee last year to look at reforming the regulations in response to industry’s outcry. Another part of the order that will likely lack bipartisan support is a call for making the head of the FAA’s commercial spaceflight division a political appointee. This job has historically been held by a career civil servant.

Ariane 6 launches European weather satellite. Europe’s new Ariane 6 rocket successfully launched for a third time on Tuesday night, carrying a satellite into orbit for weather forecasting and climate monitoring, Euronews reports. “The success of this second commercial launch confirms the performance, reliability, and precision of Ariane 6,” said Martin Sion, CEO of ArianeGroup, operator of the rocket. “Once again, the new European heavy-lift launcher meets Europe’s needs, ensuring sovereign access to space,” Sion added. It marks the second commercial flight of the rocket, which has been in development for almost a decade with the European Space Agency (ESA). It is significant as it gives Europe independent access to space and reduces its reliance on Elon Musk’s SpaceX.

Eumetsat returns to Europe … The polar-orbiting weather satellite launched by the Ariane 6 rocket this week is owned by the European Organization for the Exploitation of Meteorological Satellites, or Eumetsat. Headquartered in Germany, Eumetsat is a multinational organization that owns and operates geostationary and polar-orbiting weather satellites, watching real-time storm development over Europe and Africa, while feeding key data into global weather and climate models. Just last month, Eumetsat’s newest geostationary weather satellite launched from Florida on a SpaceX Falcon 9 rocket because of delays with the Ariane 6 program.

Rocket Lab isn’t giving up on 2025 yet. Rocket Lab continues to push for a first launch of its medium-lift Neutron rocket before the end of the year, but company executives acknowledge that schedule has no margin for error, Space News reports. It may seem unlikely, but Rocket Lab’s founder and CEO, Peter Beck, said in a conference call with investment analysts last week that the company has a “green light” schedule to debut the Neutron rocket within the next four-and-a-half months. There’s still much work to do to prepare for the first launch, and the inaugural flight seems almost certain to slip into 2026.

Launch pad nearly complete … Rocket Lab plans to host a ribbon-cutting at the Neutron rocket’s new launch pad on Wallops Island, Virginia, on August 28. This launch pad is located just south of the spaceport’s largest existing launch facility, where Northrop Grumman’s Antares rocket lifts off on resupply missions to the International Space Station. Rocket Lab has a small launch pad for its light-class Electron launcher co-located with the Antares pad at Wallops.

Chinese company reveals drone ship. The Chinese launch company iSpace has released the first photos of an ocean-going recovery ship to support the landings of reusable first-stage boosters. The company hosted a dedication ceremony in Yangzhou, China, earlier this month for the vessel, which looks similar to SpaceX’s rocket landing drone ships. In a press release, iSpace said the ship, named “Interstellar Return,” is China’s first marine rocket recovery ship, and the fifth such vessel in the world. SpaceX has three drone ships in its fleet for the Falcon 9 rocket, and Blue Origin has one for the New Glenn booster.

Rocket agnostic … The recovery ship will be compatible with various medium- and large-sized reusable rockets, iSpace said. But its main use will be as the landing site for the first stage booster for iSpace’s own Hyperbola 3 rocket, a medium-lift launcher with methane-fueled engines. The company has completed multiple vertical takeoff and landing tests of prototype boosters for the Hyperbola 3. The recovery ship measures about 100 meters long and 42 meters wide, with a displacement of 17,000 metric tons, and it has the ability to perform “intelligent unmanned operations” thanks to a dynamic positioning system, according to iSpace.

Vulcan’s first national security launch. United Launch Alliance delivered multiple US military satellites into a high-altitude orbit after a prime-time launch Tuesday night, marking an important transition from development to operations for the company’s new Vulcan rocket, Ars reports. This mission, officially designated USSF-106 by the US Space Force, was the first flight of ULA’s Vulcan rocket to carry national security payloads. Two test flights of the Vulcan rocket last year gave military officials enough confidence to certify it for launching the Pentagon’s medium-to-large space missions.

Secrecy in the fairing  … The Vulcan rocket’s Centaur upper stage released its payloads into geosynchronous orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator roughly seven hours after liftoff. One of the satellites deployed by the Vulcan rocket is an experimental navigation testbed named NTS-3. It will demonstrate new technologies that could be used on future GPS navigation satellites. But the Space Force declined to disclose any information about the mission’s other payloads.

Artemis II crew trains for nighttime ops. The four astronauts training to fly around the Moon on NASA’s Artemis II mission next year have been at Kennedy Space Center in Florida this week. One of the reasons they were at Kennedy was to run through a rehearsal for what it will be like to work at the launch pad if the Artemis II mission ends up lifting off at night. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen put on their spacesuits and rehearsed emergency procedures at Launch Complex 39B, replicating a daytime simulation they participated in last year.

Moving forward … The astronauts also went inside the Vehicle Assembly Building to practice using egress baskets they would use to quickly escape the launch pad in the event of a prelaunch emergency. The baskets are fastened to the mobile launch tower inside the VAB, where technicians are assembling and testing the Space Launch System rocket for the Artemis II mission. Later this year, the astronauts will return to Kennedy for a two-part countdown demonstration test. First, the crew members will board their Orion spacecraft once it’s stacked atop the SLS rocket inside the VAB. Then, in part two, the astronauts will again rehearse emergency evacuation procedures once the rocket rolls to the launch pad.

China’s Long March 5B flies again. China is ramping up construction of its national satellite-Internet megaconstellation with the successful deployment of another batch of Guowang satellites by a heavy-lift Long March 5B rocket on Wednesday, Space.com reports. Guowang, whose name translates as “national network,” will be operated by China SatNet, a state-run company established in 2021. The constellation will eventually consist of about 13,000 satellites if all goes to plan.

Make this make sense … Guowang is a long way from that goal. Wednesday’s launch was the eighth overall for the network, but it was the fourth for the project in less than three weeks. Each mission lofts just five to 10 Guowang spacecraft, apparently because each satellite is quite large. For comparison, SpaceX launches 24 to 28 satellites on each mission to assemble its Starlink broadband megaconstellation, which currently consists of nearly 8,100 operational spacecraft. The Long March 5B is China’s most powerful operational rocket, with a lift capacity somewhat higher than SpaceX’s Falcon 9 but below that of the Falcon Heavy. It begs the question of just how big the Guowang satellites really are, and do they have a purpose beyond broadband Internet service?
