Welcome to Edition 8.10 of the Rocket Report! Dear readers, if everything goes according to plan, four astronauts are less than six months away from traveling around the far side of the Moon and breaking free of low-Earth orbit for the first time in more than 53 years. Yes, there are good reasons to question NASA’s long-term plans for the Artemis lunar program—the woeful cost of the Space Launch System rocket, the complexity of new commercial landers, and a bleak budget outlook. But many of us who were born after the Apollo Moon landings have been waiting for this moment our whole lives. It is almost upon us.

North Korea fires solid rocket motor. North Korea said Tuesday it had conducted the final ground test of a solid-fuel rocket engine for a long-range ballistic missile in its latest advancement toward having an arsenal that could viably threaten the continental United States, the Associated Press reports. The test Monday observed by leader Kim Jong Un was the ninth of the solid rocket motor built with carbon fiber and capable of producing 1,971 kilonewtons (443,000 pounds) of thrust, more powerful than past models, according to the North’s official Korean Central News Agency.

Mobility and flexibility … Solid-fueled intercontinental ballistic missiles, or ICBMs, have advantages over liquid-fueled missiles, which have historically comprised the bulk of North Korea’s inventory. Solid rocket motors can be stored for longer periods of time and are easier to conceal, transport, and launch on demand. The new solid rocket motor will be used on a missile called the Hwasong-20, according to North Korean state media. The AP reports some analysts say North Korea may conduct another ICBM test around the end of the year, showcasing its military strength ahead of a major ruling party congress expected in early 2026.

Astrobotic eyes Andøya. US-based lunar logistics company Astrobotic and Norwegian spaceport operator Andøya Space have signed a term sheet outlining the framework for a Launch Site Agreement, European Spaceflight reports. The agreement, once finalized, will facilitate flights of Astrobotic’s Xodiac lander testbed from the Andøya Space facilities. The Xodiac vertical takeoff, vertical landing rocket was initially developed by Masten Space Systems to simulate landing on the Moon and Mars. When Masten filed for bankruptcy in 2022, Astrobotic acquired its intellectual property and assets, including the Xodiac vehicle.

Across the pond … So far, the small Xodiac rocket has flown on low-altitude atmospheric hops from Mojave, California, reaching altitudes of up to 500 meters, or 1,640 feet. The agreement between Astrobotic and Andøya paves the way for “several” Xodiac flight campaigns from Andøya Space facilities on the Norwegian coast. “Xodiac’s presence at Andøya represents a meaningful step toward delivering reliable, rapid, and cost-effective testing and demonstration capabilities to the European space market,” said Astrobotic CEO John Thornton.

Ursa Major breaks ground in Colorado. Ursa Major on Wednesday said it has broken ground on a new 400-acre site where it will test and qualify large-scale solid rocket motors for current and future missiles, including the Navy’s Standard Missile fleet, Defense Daily reports. The new site in Weld County, Colorado, north of Denver, will be ready for testing to begin in the fourth quarter of 2025. Ursa Major will be able to conduct full-scale static firings, and drop and temperature storage testing for current and future missile systems.

Seeking SRM options … Ursa Major said the new facility will support national and missile defense programs. The company’s portfolio includes solid rocket motors (SRMs) ranging from 2 inches to 22 inches in diameter for missiles like the Stinger, Javelin, and air-defense interceptors. Ursa Major aims to join industry incumbents Northrop Grumman, L3Harris, and newcomer Anduril as a major supplier of SRMs to the government. “This facility represents a major step forward in our ability to deliver qualified SRMs that are scalable, flexible, and ready to meet the evolving threat environment,” said Dan Jablonsky, CEO of Ursa Major, in a statement. “It’s a clear demonstration of our commitment and ability to rapidly advance and expand the American-made solid rocket motor industrial base that the country needs, ensuring warfighters will have the quality and quantity of SRMs needed to meet mission demands.”

Falcon 9 launches first satellites in a military megaconstellation. The first 21 satellites in a constellation that could become a cornerstone for the Pentagon’s Golden Dome missile-defense shield successfully launched from California Wednesday aboard a SpaceX Falcon 9 rocket, Ars reports. The Falcon 9 took off from Vandenberg Space Force Base, California, and headed south over the Pacific Ocean, reaching an orbit over the poles before releasing the 21 military-owned satellites to begin several weeks of activations and checkouts.

First of many … These 21 satellites will boost themselves to a final orbit at an altitude of roughly 600 miles (1,000 kilometers). The Pentagon plans to launch 133 more satellites over the next nine months to complete the build-out of the Space Development Agency’s first-generation, or Tranche 1, constellation of missile-tracking and data-relay satellites. Military officials have worked for six years to reach this moment. The Space Development Agency (SDA) was established during the first Trump administration, which made plans for an initial set of demonstration satellites that launched a couple of years ago. In 2022, the Pentagon awarded contracts for the first 154 operational spacecraft, including the ones launched Wednesday. “Back in 2019, when the SDA was stood up, it was to do two things. One was to make sure that we can do beyond line of sight targeting, and the other was to pace the threat, the emerging threat, in the missile-warning and missile-tracking domain. That’s what the focus has been,” said Gurpartap “GP” Sandhoo, the SDA’s acting director.

Another Falcon 9 was delayed three times. SpaceX scrubbed launching a communications satellite from an Indonesian company for a third consecutive day Wednesday, Spaceflight Now reports. Possible technical issues got in the way of a launch attempt Wednesday evening after back-to-back days of weather delays at Cape Canaveral Space Force Station, Florida. The Falcon 9 finally launched Thursday evening with the Boeing-built Nusantara Lima communications satellite, targeting a geosynchronous transfer orbit. It’s the latest satellite from the Indonesian company Pasifik Satelit Nusantara.

A declining market … This was just the fifth geosynchronous communications satellite to launch on a commercial rocket this year, all by SpaceX. There were 21 such satellites that launched on commercial vehicles in 2015, including SpaceX’s Falcon 9, Europe’s Ariane 5, Russia’s Proton, ULA’s Atlas V, and Japan’s H-IIA. Much of the world’s launch capacity today is used to deploy smaller communications satellites into low-Earth orbit, primarily for broadband connectivity rather than for the video broadcast market once dominated by higher-altitude geosynchronous satellites.

Putin urges Russia to build more rocket engines. Russian President Vladimir Putin urged aerospace industry leaders on September 5 to press on with efforts to develop booster rocket engines for space launch vehicles and build on Russia’s longstanding reputation as a leader in space technology, Reuters reports. Putin, who spent the preceding days in China and the Russian far eastern port of Vladivostok, flew to the southern Russian city of Samara, where he met industry specialists and toured the Kuznetsov design bureau engine manufacturing plant.

A shell of its former self … “It is important to consistently renew production capacity in terms of engines for booster rockets,” Russian news agencies quoted Putin as saying during the visit. “And in doing so, we must not only meet our own current and future needs but also move actively on world markets and be successful competitors.” The Kuznetsov plant in Samara builds medium-class RD-107 and RD-108 engines for Russia’s Soyuz-2 rockets, which launch Russian military satellites and crew and cargo to the International Space Station. Their designs can be traced to the dawn of the Space Age nearly 70 years ago. Meanwhile, the outlook for heavier-duty Russian rocket engines is murky, at best. Russia’s most-flown large rocket engine in the post-Cold War era, the RD-180, produced by a company called Energomash, is out of production after the end of sales to the United States.

India nabs a noteworthy launch contract. Astroscale, a satellite servicing and space debris mitigation company based in Japan, has selected India’s Polar Satellite Launch Vehicle (PSLV) to deliver a small satellite named ISSA-J1 to orbit in 2027. This is an interesting mission. The ISSA-J1 spacecraft will fly up to two large pieces of satellite debris in orbit to image and inspect them. ISSA-J1, developed in partnership with the Japanese government, is one in a series of Astroscale missions testing different ways of approaching, monitoring, capturing, and refueling other objects in space. The launch agreement was signed between Astroscale and NewSpace India Limited, the commercial arm of India’s space agency.

Rideshare not an option … “We selected NSIL after thorough evaluations of more than 10 launch service providers over the past year, considering technical capabilities, track record, cost, and other elements,” said Eddie Kato, president and managing director of Astroscale Japan. India’s PSLV is right-sized for a mission like this. ISSA-J1 is a rarity in that it must launch on a dedicated rocket because it has to reach a specific orbit to line up with the pieces of space debris it will approach and inspect. Rideshare launches, such as those that routinely fly on SpaceX’s Falcon 9 rocket, are cheaper but go to standard orbits popular for many different types of satellite missions. A dedicated launch on a Falcon 9 would presumably have been more expensive than a flight on India’s smaller PSLV. Rocket Lab’s Electron, another rocket popular for dedicated launches of small satellites, lacks the performance required for Astroscale’s mission.

Russian cargo en route to ISS. Another cargo ship is flying to humanity’s orbital outpost with the successful launch of Russia’s Progress MS-32 supply freighter Thursday from the Baikonur Cosmodrome in Kazakhstan, NASASpaceflight.com reports. The supply ship launched aboard a Soyuz-2.1a rocket and arrived in orbit about nine minutes later, kicking off a two-day pursuit of the International Space Station. This was the 300th launch of an assembly, crew, or cargo mission to the ISS since 1998, including a handful of missions that didn’t reach the complex due to rocket or spacecraft failures.

Important stuff … The Progress MS-32 cargo craft will dock with the aft port of the space station’s Russian Zvezda service module Saturday. The payloads flying on the Progress mission include food, experiments, clothing, water, air, and propellant to be pumped into the space station’s onboard tanks. The spacecraft will also reboost the lab’s orbit.

Metallic tiles? Not so great. It has been two weeks since SpaceX’s last Starship test flight, and engineers have diagnosed issues with its heat shield, identified improvements, and developed a preliminary plan for the next time the ship heads into space, Ars reports. Bill Gerstenmaier, a SpaceX executive in charge of build and flight reliability, presented the findings Monday at the American Astronautical Society’s Glenn Space Technology Symposium in Cleveland. The test flight went “extremely well,” Gerstenmaier said, but he noted some important lessons learned with the ship’s heat shield.

Crunch wrap reigns supreme … “We were essentially doing a test to see if we could get by with non-ceramic tiles, so we put three metal tiles on the side of the ship to see if they would provide adequate heat control, because they would be simpler to manufacture and more durable than the ceramic tiles. It turns out they’re not,” Gerstenmaier said. “The metal tiles… didn’t work so well.” One bright spot with the heat shield was the performance of a new experimental material around and under the tiles. “We call it crunch wrap,” Gerstenmaier said. “It’s like a wrapping paper that goes around each tile.” On the next Starship flight, SpaceX will likely cover more parts of the heat shield with this crunch wrap material. Gerstenmaier said the inaugural flight of Starship Version 3, with upgraded engines and more fuel, is now set to occur next year.

An SLS compromise might be afoot in DC. The Trump administration is seeking to cancel NASA’s Space Launch System rocket after two more flights, but key lawmakers in Congress, including Republican Sen. Ted Cruz of Texas, aren’t ready to go along.  So is this an impasse? Possibly not, as sources say the White House and Congress may not be all that far apart on how to handle this. The solution involves canceling part of the SLS rocket now, but not all of it, Ars reports.

Goodbye EUS? … The compromise might be to cancel a large new upper stage for the SLS rocket called the Exploration Upper Stage. This would save NASA billions of dollars, and the agency could instead procure commercial upper stages, such as those built by United Launch Alliance or Blue Origin, to fly on SLS rockets after NASA’s Artemis III mission. It would also eliminate the need for NASA to finish building an expensive new launch tower at Kennedy Space Center, Florida. The upper stage flying on the first three SLS missions is no longer in production. Sources indicated to Ars that Blue Origin has already begun work on a modified version of its New Glenn upper stage that could fit within the shroud of the SLS rocket.

Congress and Trump may compromise on the SLS rocket by axing its costly upper stage

exploration upper stage, NASA, sls, Space, Trump / /

There are myriad questions about how NASA’s budget process will play out in the coming weeks, with the start of the new fiscal year on October 1 looming.

For example, the Trump administration may seek to shut off dozens of science missions that are either already in space or in development. Although Congress has signaled a desire to keep these missions active, absent a confirmed budget, the White House has made plans to turn off the lights.

Some answers may be forthcoming this week, as the House Appropriations Committee will take up the Commerce, Justice, and Science budget bill on Wednesday morning. However great uncertainty remains about whether there will be a budget passed by October 1 (unlikely), a continuing resolution, or a government shutdown.

Behind the scenes, discussions are also taking place about NASA’s Artemis Program in general and the future of the Space Launch System rocket specifically.

$4 billion a launch is too much

From the beginning, the second Trump administration has sought to cancel the costly, expendable rocket. Some officials wanted to end the rocket immediately,  but eventually the White House decided to push for cancellation after Artemis III. This seemed prudent because it allowed the United States the best possible chance to land humans back on the Moon before China got there, and then transition to a more affordable lunar program as quickly as possible.

Congress, particularly US Sen. Ted. Cruz, R-Texas, was not amenable. And so, in supplemental funding as part of the “One Big Beautiful Bill,” Cruz locked in billions of dollars to ensure that Artemis IV and Artemis V flew on the SLS rocket, with the promise of additional missions.

Since the release of its budget proposal in May, which called for an end to the SLS rocket after Artemis III, the White House has largely been silent, offering no response to Congress. However that changed last week, when interim NASA Administrator Sean Duffy addressed the issue on a podcast hosted by one of the agency’s public relations officials, Gary Jordan:

GOP may finally succeed in unrelenting quest to kill two NASA climate satellites

Before satellite measurements, researchers relied on estimates and data from a smattering of air and ground-based sensors. An instrument on Mauna Loa, Hawaii, with the longest record of direct carbon dioxide measurements, is also slated for shutdown under Trump’s budget.

It requires a sustained, consistent dataset to recognize trends. That’s why, for example, the US government has funded a series of Landsat satellites since 1972 to create an uninterrupted data catalog illustrating changes in global land use.

But NASA is now poised to shut off OCO-2 and OCO-3 instead of thinking about how to replace them when they inevitably cease working. The missions are now operating beyond their original design lives, but scientists say both instruments are in good health.

Can anyone replace NASA?

Research institutes in Japan, China, and Europe have launched their own greenhouse gas-monitoring satellites. So far, all of them lack the spatial resolution of the OCO instruments, meaning they can’t identify emission sources with the same precision as the US missions. A new European mission called CO2M will come closest to replicating OCO-2 and OCO-3, but it won’t launch until 2027.

Several private groups have launched their own satellites to measure atmospheric chemicals, but these have primarily focused on detecting localized methane emissions for regulatory purposes, and not on global trends.

One of the newer groups in this sector, known as the Carbon Mapper Coalition, launched its first small satellite last year. This nonprofit consortium includes contributors from JPL, the same lab that spawned the OCO instruments, as well as Planet Labs, the California Air Resources Board, universities, and private investment funds.

Government leaders in Montgomery County, Maryland, have set a goal of reducing greenhouse gas emissions by 80 percent by 2027, and 100 percent by 2035. Mark Elrich, the Democratic county executive, said the pending termination of NASA’s carbon-monitoring missions “weakens our ability to hold polluters accountable.”

“This decision would … wipe out years of research that helps us understand greenhouse gas emissions, plant health, and the forces that are driving climate change,” Elrich said in a press conference last month.

NASA’s acting chief “angry” about talk that China will beat US back to the Moon

administrator, artemis, china, NASA, orion, Sean Duffy, sls, Space, startship / /

NASA’s interim administrator, Sean Duffy, said Thursday he has heard the recent talk about how some people are starting to believe that China will land humans on the Moon before NASA can return there with the Artemis Program.

“We had testimony that said NASA will not beat China to the Moon,” Duffy remarked during an all-hands meeting with NASA employees. “That was shade thrown on all of NASA. I heard it, and I gotta tell you what, maybe I am competitive, I was angry about it. I can tell you what, I’ll be damned if that is the story that we write. We are going to beat the Chinese to the Moon.”

Duffy’s remarks followed a Congressional hearing on Wednesday during which former Congressman Jim Bridenstine, who served as NASA administrator during President Trump’s first term, said China had pulled ahead of NASA and the United States in the second space race.

“Unless something changes, it is highly unlikely the United States will beat China’s projected timeline to the Moon’s surface,” said Bridenstine, who led the creation of the Artemis Program in 2019. China has said multiple times that it intends to land taikonuats on the Moon before the year 2030.

A lot of TV appearances

Duffy’s remarks were characteristic of his tenure since his appointment two months ago by Trump to serve as interim administrator of the space agency. He has made frequent appearances on Fox News and offered generally upbeat views of NASA’s position in its competition with China for supremacy in space. And on Friday, in a slickly produced video, he said, “I’m committed to getting us back to the Moon before President Trump leaves office.”

Sources have said Duffy, already a cabinet member as the secretary of transportation, is also angling to remove the “interim” from his NASA administrator title. Like Bridenstine, he has a capable political background and politics that align with the Trump administration. He is an excellent public speaker and knows the value of speaking to the president through Fox News. To date, however, he has shown limited recognition of the reality of the current competition with China.

lull-in-falcon-heavy-missions-opens-window-for-spacex-to-build-new-landing-pads

Lull in Falcon Heavy missions opens window for SpaceX to build new landing pads

Commercial space, falcon 9, falcon heavy, Federal Aviation Administration, launch, NASA, reusability, Science, Space, spacex / /

SpaceX’s goal for this year is 170 Falcon 9 launches, and the company is on pace to come close to this target. Most Falcon 9 launches carry SpaceX’s own Starlink broadband satellites into orbit. The FAA’s environmental approval opens the door for more flights from SpaceX’s busiest launch pad.

But launch pad availability is not the only hurdle limiting how many Falcon 9 flights can take off in a year. There’s also the rate of production for Falcon 9 upper stages, which are new on each flight, and the time it takes for each vessel in SpaceX’s fleet of drone ships (one in California, two in Florida) to return to port with a recovered booster and redeploy back to sea again for the next mission. SpaceX lands Falcon 9 boosters on offshore drone ships after most of its launches and only brings the rocket back to an onshore landing on missions carrying lighter payloads to orbit.

When a Falcon 9 booster does return to landing on land, it targets one of SpaceX’s recovery zones at military-run spaceports in Florida and California. SpaceX’s landing zone at Vandenberg Space Force Base in California is close to the Falcon 9 launch pad there.

The Space Force wants SpaceX, and potentially other future reusable rocket companies, to replicate the side-by-side launch and landing pads at Cape Canaveral.

To do that, the FAA also gave the green light Wednesday for SpaceX to construct and operate a new rocket landing zone at SLC-40 and conduct up to 34 first-stage booster landings there each year. The landing zone will consist of a 280-foot diameter concrete pad surrounded by a 60-foot-wide gravel apron. The landing zone’s broadest diameter, including the apron, will measure 400 feet.

The location of SpaceX’s new rocket landing pad is shown with the red circle, approximately 1,000 feet northeast of the Falcon 9 rocket’s launch pad at Space Launch Complex-40. Credit: Google Maps/Ars Technica

SpaceX is in an earlier phase of planning for a Falcon landing pad at historic Launch Complex-39A at NASA’s Kennedy Space Center, just a few miles north of SLC-40. SpaceX uses LC-39A as a launch pad for most Falcon 9 crew launches, all Falcon Heavy missions, and, in the future, flights of the company’s gigantic next-generation rocket, Starship. SpaceX foresees Starship as a replacement for Falcon 9 and Falcon Heavy, but the company’s continuing investment in Falcon-related infrastructure shows the workhorse rocket will stick around for a while.

Former NASA chief says United States likely to lose second lunar space race

artemis, congress, Gateway, NASA, Senate, sls rocket, Space / /

The hearing, titled “There’s a Bad Moon on the Rise: Why Congress and NASA Must Thwart China in the Space Race,” had no witnesses who disagreed with this viewpoint. They included Allen Cutler, CEO of the Coalition for Deep Space Exploration, the chief lobbying organization for SLS, Orion, and Gateway; Jim Bridenstine, former NASA Administrator who now leads government operations for United Launch Alliance; Mike Gold of Redwire, a Gateway contractor; and Lt. General John Shaw, former Space Command official.

The hearing before the committee chaired by Cruz, Commerce, Science, and Transportation, included the usual mishmash of parochial politics, lobbying for traditional space, back slapping, and fawning—at one point, Gold, a Star Trek fan, went so far as to assert that Cruz is the “Captain Kirk” of the US Senate.

Beyond this, however, there was a fair amount of teeth gnashing about the fact that the United States faces a serious threat from China, which appears to be on course to put humans on the Moon before NASA can return there with the Artemis Program. China aims to land humans at the South Pole before the year 2030.

NASA likely to lose “race”

Bridenstine, who oversaw the creation of the Artemis Program half a decade ago, put it most bluntly: “Unless something changes, it is highly unlikely the United States will beat China’s projected timeline to the Moon’s surface,” he said.

Bridenstine and others on the panel criticized the complex nature of SpaceX’s Starship-based lunar lander, which NASA selected in April 2021 as a means to get astronauts down to the lunar surface and back. The proposal relies on Starship being refueled in low-Earth orbit by multiple Starship tanker launches.

spacex’s-latest-dragon-mission-will-breathe-more-fire-at-the-space-station

SpaceX’s latest Dragon mission will breathe more fire at the space station

Commercial space, dragon, international space station, NASA, Science, Space, spacex / /

“Our capsule’s engines are not pointed in the right direction for optimum boost,” said Sarah Walker, SpaceX’s director of Dragon mission management. “So, this trunk module has engines pointed in the right direction to maximize efficiency of propellant usage.”

When NASA says it’s the right time, SpaceX controllers will command the Draco thrusters to ignite and gently accelerate the massive 450-ton complex. All told, the reboost kit can add about 20 mph, or 9 meters per second, to the space station’s already-dizzying speed, according to Walker.

Spetch said that’s roughly equivalent to the total reboost impulse provided by one-and-a-half Russian Progress cargo vehicles. That’s about one-third to one-fourth of the total orbit maintenance the ISS needs in a year.

“The boost kit will help sustain the orbiting lab’s altitude, starting in September, with a series of burns planned periodically throughout the fall of 2025,” Spetch said.

After a few months docked at the ISS, the Dragon cargo capsule will depart and head for a parachute-assisted splashdown in the Pacific Ocean off the coast of California. SpaceX will recover the pressurized capsule to fly again, while the trunk containing the reboost kit will jettison and burn up in the atmosphere.

While this mission is SpaceX’s 33rd cargo flight to the ISS under the auspices of NASA’s multibillion-dollar Commercial Resupply Services contract, it’s also SpaceX’s 50th overall Dragon mission to the outpost. This tally includes 17 flights of the human-rated Crew Dragon.

“With CRS-33, we’ll mark our 50th voyage to ISS,” Walker said. “Just incredible. Together, these missions have (carried) well over 300,000 pounds of cargo and supplies to the orbiting lab and well over 1,000 science and research projects that are not only helping us to understand how to live and work effectively in space… but also directly contributing to critical research that serves our lives here on Earth.”

Future Dragon trunks will be able to accommodate a reboost kit or unpressurized science payloads, depending on NASA’s needs at the space station.

The design of the Dragon reboost kit is a smaller-scale version of what SpaceX will build for a much larger Dragon trunk under a $843 million contract signed with NASA last year for the US Deorbit Vehicle. This souped-up Dragon will dock with the ISS and steer it back into the atmosphere after the lab’s decommissioning in the early 2030s. The deorbit vehicle will have 46 Draco thrusters—16 to control the craft’s orientation and 30 in the trunk to provide the impulse needed to drop the station out of orbit.

SpaceX is gearing up for another Starship launch after three straight disappointing test flights.

STARBASE, Texas—A beehive of aerospace technicians, construction workers, and spaceflight fans descended on South Texas this weekend in advance of the next test flight of SpaceX’s gigantic Starship rocket, the largest vehicle of its kind ever built.

Towering 404 feet (123.1 meters) tall, the rocket was supposed to lift off during a one-hour launch window beginning at 6: 30 pm CDT (7: 30 pm EDT; 23: 30 UTC) Sunday. But SpaceX called off the launch attempt about an hour before liftoff to investigate a ground system issue at Starbase, located a few miles north of the US-Mexico border.

SpaceX didn’t immediately confirm when it might try again to launch Starship, but it could happen as soon as Monday evening at the same time.

It will take about 66 minutes for the rocket to travel from the launch pad in Texas to a splashdown zone in the Indian Ocean northwest of Australia. You can watch the test flight live on SpaceX’s official website. We’ve also embedded a livestream from Spaceflight Now and LabPadre below.

This will be the 10th full-scale test flight of Starship and its Super Heavy booster stage. It’s the fourth flight of an upgraded version of Starship conceived as a stepping stone to a more reliable, heavier-duty version of the rocket designed to carry up to 150 metric tons, or some 330,000 pounds, of cargo to pretty much anywhere in the inner part of our Solar System.

But this iteration of Starship, known as Block 2 or Version 2, has been anything but reliable. After reeling off a series of increasingly successful flights last year with the first-generation Starship and Super Heavy booster, SpaceX has encountered repeated setbacks since debuting Starship Version 2 in January.

Now, there are just two Starship Version 2s left to fly, including the vehicle poised for launch this week. Then, SpaceX will move on to Version 3, the design intended to go all the way to low-Earth orbit, where it can be refueled for longer expeditions into deep space.

Starship’s promised cargo capacity is unparalleled in the history of rocketry. The privately developed rocket’s enormous size, coupled with SpaceX’s plan to make it fully reusable, could enable cargo and human missions to the Moon and Mars. SpaceX’s most conspicuous contract for Starship is with NASA, which plans to use a version of the ship as a human-rated Moon lander for the agency’s Artemis program. With this contract, Starship is central to the US government’s plans to try to beat China back to the Moon.

Closer to home, SpaceX intends to use Starship to haul massive loads of more powerful Starlink Internet satellites into low-Earth orbit. The US military is interested in using Starship for a range of national security missions, some of which could scarcely be imagined just a few years ago. SpaceX wants its factory to churn out a Starship rocket every day, approximately the same rate Boeing builds its workhorse 737 passenger jets.

Starship, of course, is immeasurably more complex than an airliner, and it sees temperature extremes, aerodynamic loads, and vibrations that would destroy a commercial airplane.

For any of this to become reality, SpaceX needs to begin ticking off a lengthy to-do list of technical milestones. The interim objectives include things like catching and reusing Starships and in-orbit ship-to-ship refueling, with a final goal of long-duration spaceflight to reach the Moon and stay there for weeks, months, or years. For a time late last year, it appeared as if SpaceX might be on track to reach at least the first two of these milestones by now.

Instead, SpaceX’s schedule for catching and reusing Starships, and refueling ships in orbit, has slipped well into next year. A Moon landing is probably at least several years away. And a touchdown on Mars? Maybe in the 2030s. Before Starship can sniff those milestones, engineers must get the rocket to survive from liftoff through splashdown. This would confirm that recent changes made to the ship’s heat shield work as expected.

Three test flights attempting to do just this ended prematurely in January, March, and May. These failures prevented SpaceX from gathering data on several different tile designs, including insulators made of ceramic and metallic materials, and a tile with “active cooling” to fortify the craft as it reenters the atmosphere.

The heat shield is supposed to protect the rocket’s stainless steel skin from temperatures reaching 2,600° Fahrenheit (1,430° Celsius). During last year’s test flights, it worked well enough for Starship to guide itself to an on-target controlled splashdown in the Indian Ocean, halfway around the world from SpaceX’s launch site in Starbase, Texas.

But the ship lost some of its tiles during each flight last year, causing damage to the ship’s underlying structure. While this wasn’t bad enough to prevent the vehicle from reaching the ocean intact, it would cause difficulties in refurbishing the rocket for another flight. Eventually, SpaceX wants to catch Starships returning from space with giant robotic arms back at the launch pad. The vision, according to SpaceX founder and CEO Elon Musk, is to recover the ship, quickly mount it on another booster, refuel it, and launch it again.

If SpaceX can accomplish this, the ship must return from space with its heat shield in pristine condition. The evidence from last year’s test flights showed engineers had a long way to go for that to happen.

The Starship setbacks this year have been caused by problems in the ship’s propulsion and fuel systems. Another Starship exploded on a test stand in June at SpaceX’s sprawling rocket development facility in South Texas. SpaceX engineers identified different causes for each of the failures. You can read about them in our previous story.

Apart from testing the heat shield, the goals for this week’s Starship flight include testing an engine-out capability on the Super Heavy booster. Engineers will intentionally disable one of the booster’s Raptor engines used to slow down for landing, and instead use another Raptor engine from the rocket’s middle ring. At liftoff, 33 methane-fueled Raptor engines will power the Super Heavy booster off the pad.

SpaceX won’t try to catch the booster back at the launch pad this time, as it did on three occasions late last year and earlier this year. The booster catches have been one of the bright spots for the Starship program as progress on the rocket’s upper stage floundered. SpaceX reused a previously flown Super Heavy booster for the first time on the most recent Starship launch in May.

The booster landing experiment on this week’s flight will happen a few minutes after launch over the Gulf of Mexico east of the Texas coastline. Meanwhile, six Raptor engines will fire until approximately T+plus 9 minutes to accelerate the ship, or upper stage, into space.

The ship is programmed to release eight Starlink satellite simulators from its payload bay in a test of the craft’s payload deployment mechanism. That will be followed by a brief restart of one of the ship’s Raptor engines to adjust its trajectory for reentry, set to begin around 47 minutes into the mission.

If Starship makes it that far, that will be when engineers finally get a taste of the heat shield data they were hungry for at the start of the year.

This story was updated at 8: 30 pm EDT after SpaceX scrubbed Sunday’s launch attempt.

After recent tests, China appears likely to beat the United States back to the Moon

An expert explains why this will be enormously bad for the United States.

In recent weeks, the secretive Chinese space program has reported some significant milestones in developing its program to land astronauts on the lunar surface by the year 2030.

On August 6, the China Manned Space Agency successfully tested a high-fidelity mockup of its 26-ton “Lanyue” lunar lander. The test, conducted outside of Beijing, used giant tethers to simulate lunar gravity as the vehicle fired main engines and fine control thrusters to land on a cratered surface and take off from there.

“The test,” said the agency in an official statement, “represents a key step in the development of China’s manned lunar exploration program, and also marks the first time that China has carried out a test of extraterrestrial landing and takeoff capabilities of a manned spacecraft.”

As part of the statement, the space agency reconfirmed that it plans to land its astronauts on the Moon “before” 2030.

Then, last Friday, the space agency and its state-operated rocket developer, the China Academy of Launch Vehicle Technology, successfully conducted a 30-second test firing of the Long March 10 rocket’s center core with its seven YF-100K engines that burn kerosene and liquid oxygen. The primary variant of the rocket will combine three of these cores to lift about 70 metric tons to low-Earth orbit.

These successful efforts followed a launch escape system test of the new Mengzhou spacecraft in June. A version of this spacecraft is planned for lunar missions.

On track for 2030

Thus, China’s space program is making demonstrable progress in all three of the major elements of its lunar program: the large rocket to launch a crew spacecraft, which will carry humans to lunar orbit, plus the lander that will take astronauts down to the surface and back. This work suggests that China is on course to land on the Moon before the end of this decade.

For the United States and its allies in space, there are reasons to be dismissive of this. For one, NASA landed humans on the Moon nearly six decades ago with the Apollo Program. Been there, done that.

Moreover, the initial phases of the Chinese program look derivative of Apollo, particularly a lander that strikingly resembles the Lunar Module. NASA can justifiably point to its Artemis Program and say it is attempting to learn the lessons of Apollo—that the program was canceled because it was not sustainable. With its lunar landers, NASA seeks to develop in-space propellant storage and refueling technology, allowing for lower cost, reusable lunar missions with the capability to bring much more mass to the Moon and back. This should eventually allow for the development of a lunar economy and enable a robust government-commercial enterprise.

But recent setbacks with SpaceX’s Starship vehicle–one of two lunar landers under contract with NASA, alongside Blue Origin’s Mark 2 lander—indicate that it will still be several years until these newer technologies are ready to go. So it’s now probable that China will “beat” NASA back to the Moon this decade and win at least the initial heat of this new space race.

To put this into perspective, Ars connected with Dean Cheng, one of the most respected analysts on China, space policy, and the geopolitical implications of the new space competition. He was also a researcher at the Heritage Foundation for 13 years, where he focused on China. (He was not involved with Project 2025.) Now “sort of” retired, in his own words, Cheng is presently a non-resident fellow at the George Washington University Space Policy Institute.

The implications of this for the West

Ars: How significant was the Lanyue lander demonstration? Does this indicate the Chinese space program remains on track to land humans on the Moon by or before 2030?

Dean Cheng: The Lanyue lander is significant because it’s part of the usual Chinese “crawl-walk-run” approach to major space (and other scientific) projects. The [People’s Republic of China] can benefit from other people’s experiences (much of NASA’s information is open), but they still have to build and operate the spacecraft themselves. So the test of the Lanyue lander, successful or not, is an important part of that process.

Note that the Chinese also this week had a successful static test of the LM-10, which is their lunar SLV (satellite launch vehicle). This, along with the Lanyue, indicates that the Chinese lunar program is pushing ahead. The LM-10, even more than the Lanyue, is significant because it’s a new launch vehicle, in the wake of problems with the LM-5 and the cancellation of the LM-9 (which was probably their Saturn-V equivalent).

Ars: How likely is it that China lands humans on the Moon before NASA can return there with the Artemis Program?

Cheng: At the rate things are going, sadly, it seems quite likely that the Chinese will land on the Moon before NASA can return to the Moon.

Ars: What would the geopolitical impact be if China beats the United States back to the Moon?

Cheng: The geopolitical impact of the Chinese beating the US to the Moon (where we are returning) would be enormous.

Ars: How so?

Cheng: It means the end of American exceptionalism. One of the hallmarks of the post-1969 era was that only the United States had been able to land someone on the Moon (or any other celestial body). This was bound to end, but the constant American refrain of “We’ve put a man on the Moon, we can do anything” will certainly no longer resonate.

It means China can do “big” things, and the United States cannot. The US cannot even replicate projects it undertook 50 (or more) years ago. The optics of “the passing of the American age” would be evident—and that in turn would absolutely affect other nations’ perceptions of who is winning/losing the broader technological and ideological competition between the US and the PRC.

A few years back, there was talk of “The Beijing Consensus” as an alternative to the “Washington Consensus.” The Washington Consensus posited that the path forward was democracy, pluralism, and capitalism. The Beijing consensus argued that one only needed economic modernization. That, in fact, political authoritarianism was more likely to lead to modernization and advancement. This ideological element would be reinforced if Beijing can do the “big” things but the US cannot.

And what will be the language of cis-lunar space? The Chinese are not aiming to simply go to the Moon. Their choice of landing sites (most likely the South Pole) suggests an intent to establish longer-term facilities and presence. If China regularly dispatches lunar missions (not just this first one), then it will rightfully be able to argue that Chinese should be a language, if not the language, of lunar/cis-lunar space traffic management. As important, China will have an enormous say over technical standards, data standards, etc., for cis-lunar activities. The PRC has already said it will be deploying a lunar PNT (positioning, navigation, and timing) network and likely a communications system, (given the BeiDou’s dual capabilities in this regard).

Ars: Taking the longer view, is the United States or China better positioned (i.e., US spending on defense, reusable in-space architecture vs Chinese plans) to dominate cislunar space between now and the middle of this century?

Cheng: On paper, the US has most of the advantages. We have a larger economy, more experience in space, extant space industrial capacity for reusable space launch, etc. But we have not had programmatic stability so that we are consistently pursuing the same goal over time. During Trump-1, the US said it would go to the Moon with people by 2024. Here we are, halfway through 2025. Trump-2 seems to once again be swinging wildly from going (back) to the Moon to going to Mars. Scientific and engineering advances don’t do well in the face of such wild swings and inconstancy.

By contrast, the Chinese are stable, systematic. They pursue a given goal (e.g., human spaceflight, a space station) over decades, with persistence and programmatic (both budgetarily and in terms of goals) stability. So I expect that the Chinese will put a Chinese person on the Moon by 2030 and follow that with additional crewed and unmanned facilities. This will be supported by a built-out infrastructure of lunar PNT/comms. The US will almost certainly put people on the Moon in a landing in the next several years, but then what? Is Lunar Gateway going to be real? How often will the US go to the Moon, as the Chinese go over and over?

Ars: Do you have any advice for the Trump administration in order to better compete with China in this effort to not only land on the Moon but have a dominant presence there?

Cheng: The Trump administration needs to make a programmatic commitment to some goal, whether the Moon or Mars. It needs to mobilize Congress and the public to support that goal. It needs to fund that goal, but as important, it also needs to have a high-level commitment and oversight, such as the VP and the National Space Council in the first Trump administration. There is little/no obvious direction at the moment for where space is going in this administration, and what its priorities are.

This lack of direction then affects the likelihood that industry, whether big business or entrepreneurs, can support whatever efforts do emerge. If POTUS wants to rely more on entrepreneurial business (a reasonable approach), he nonetheless needs to provide indications of this. It would help to also provide incentives, e.g., a follow-on to the Ansari and X-prizes, which did lead to a blossoming of innovation.

NASA’s acting chief calls for the end of Earth science at the space agency

Earth science, NASA, Sean Duffy, Space / /

Sean Duffy, the acting administrator of NASA for a little more than a month, has vowed to make the United States great in space.

With a background as a US Congressman, reality TV star, and television commentator, Duffy did not come to the position with a deep well of knowledge about spaceflight. He also already had a lot on his plate, serving as the secretary of transportation, a Cabinet-level position that oversees 55,000 employees across 13 agencies.

Nevertheless, Duffy is putting his imprint on the space agency, seeking to emphasize the agency’s human exploration plans, including the development of a lunar base, and ending NASA’s efforts to study planet Earth and its changing climate.

Duffy has not spoken much with reporters who cover the space industry, but he has been a frequent presence on Fox News networks, where he previously worked as a host. On Thursday, he made an 11-minute appearance on “Mornings with Maria,” a FOX Business show hosted by Maria Bartiromo to discuss NASA.

NASA should explore, he says

During this appearance, Duffy talked up NASA’s plans to establish a permanent presence on the Moon and his push to develop a nuclear reactor that could provide power there. He also emphasized his desire to end NASA’s focus on studying the Earth and understanding how the planet’s surface and atmosphere are changing. This shift has been a priority of the Trump Administration at other federal agencies.

“All the climate science, and all of the other priorities that the last administration had at NASA, we’re going to move aside, and all of the science that we do is going to be directed towards exploration, which is the mission of NASA,” Duffy said during the appearance. “That’s why we have NASA, to explore, not to do all of these Earth sciences.”

Rocket Report: Ariane 6 beats Vulcan to third launch; China’s first drone ship

Why is China’s heavy-lift Long March 5B able to launch only 10 Guowang satellites at a time?

Wearing their orange launch and reentry spacesuits, Artemis II commander Reid Wiseman (bottom) and pilot Victor Glover (top) walk out of an emergency egress basket during nighttime training at Launch Complex 39B.

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.

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.

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?

Gemini and Apollo astronaut

James Lovell, a member of humanity’s first trip to the moon and commander of NASA’s ill-fated Apollo 13 mission, has died at the age of 97.

Lovell’s death on Thursday was announced by the space agency.

“NASA sends its condolences to the family of Capt. Jim Lovell, whose life and work inspired millions of people across the decades,” said acting NASA Administrator Sean Duffy in a statement on Friday. “Jim’s character and steadfast courage helped our nation reach the moon and turned a potential tragedy into a success from which we learned an enormous amount. We mourn his passing even as we celebrate his achievements.”

A four-time Gemini and Apollo astronaut, Lovell was famously portrayed in the 1995 feature film Apollo 13. The movie dramatized his role as the leader of what was originally planned as NASA’s third moon landing, but instead became a mission of survival after an explosion tore through his spacecraft’s service module.

“I know today when I came out many of you were expecting Tom Hanks, but you’re going to have to settle for little old me,” Lovell often said at his public appearances after the movie was released.

Practicing for the moon

Selected with NASA’s second group of astronauts in 1962, Lovell first launched aboard Gemini 7, the first mission to include a rendezvous with another crewed spacecraft (Gemini 6). Lifting off on a Titan II rocket on December 4, 1965, Lovell and the mission’s commander, Frank Borman, had one goal: to spend two weeks in Earth orbit in preparation for the later Apollo missions to the moon.

“It was very exciting to me,” said Lovell in a 1999 NASA oral history interview. “I mean, it was tedious work, you know, two weeks. We did have a break when [Wally] Schirra and [Tom] Stafford came up [on Gemini 6] and rendezvoused with us. And then they were up, I think, 24 hours and they went back down again. And we stayed up there for the full time. But it was quite rewarding.”

At 13 days, 18 hours, 35 minutes and one second, Gemini 7 was the longest space flight until a Russian Soyuz mission surpassed it in 1970. Lovell and Borman continued to hold the US record until the first crewed mission to Skylab, the nation’s first space station, in 1973.

Lovell then commanded Gemini 12, the final flight of the program, which launched on November 11, 1966. Only four days long, the mission stood out for demonstrating all of the skills needed to send astronauts to the moon, including rendezvousing and docking with an Agena target and the first successful spacewalks conducted by crewmate Buzz Aldrin.

“Buzz completed three spacewalks of about 5.5 hours and everything was fine,” said Lovell. “[We did] everything we were supposed to do, and [had] no problem at all. So, it was a major turning point in the ability to work outside a spacecraft.”

First and fifth

Lovell made his first trip to the moon as a member of the first-ever crew to fly to another celestial body. Reunited with Borman and joined by William “Bill” Anders, Lovell launched on Apollo 8 on December 21, 1968. The mission was also the first crewed flight of the Saturn V, the massive rocket designed to send astronauts from Earth to the moon.

“You had to pinch yourself,” Lovell said of the journey out. “Hey, we’re really going to the moon!” I mean, “You know, this is it!”

Lovell and his Apollo 8 crewmates were the first to see the far side of the moon with their own eyes and the first to witness “Earthrise”—the sight of our home planet rising above the lunar horizon—their photographs of such were later credited with inspiring the environmental movement.

“We were so curious, so excited about being at the moon that we were like three school kids looking into a candy store window, watching those ancient old craters go by from—only 60 miles [97 kilometers] above the surface,” said Lovell.

Splashing down on December 27, 1968, the Apollo 8 mission brought to a close a year that had otherwise been troubled with riots, assassinations, and an ongoing war. A telegram sent to the crew after they were home said, “You saved 1968.”

“I was part of a thing that finally gave an uplift to the American people about doing something positive, which was really—that’s why I say Apollo 8 was really the high point of my space career,” said Lovell.

Even before launching on Apollo 13 on April 11, 1970, Lovell had decided it was going to be his last. At 42, he was the first person to launch four times into space. Had the flight gone to plan, he would have become the fifth person to walk on the moon and the first to wear red commander stripes while do so.

Instead, there was a “problem.”

“I don’t know why I did this, but I looked out the right window, and that’s when I saw that at a high rate of speed, gas was escaping from the spacecraft. You could see a little plume of it,” said Lovell in an April 2000 interview with collectSPACE. “I then glanced at the oxygen gauges and one read zero and another was in the process of going down.”

“That is when I really felt we were in a very dangerous situation,” he said.

Lovell and his Apollo 13 crewmates Fred Haise and John “Jack” Swigert splashed down safely on April 17, 1970. In total, Lovell logged 29 days, 19 hours and three minutes on his four spaceflights.

Lovell was the 22nd person to enter orbit, and the 28th to fly into space, according to the Association of Space Explorers’ Registry of Space Travelers.

From the cockpit to the board

Born on March 25, 1928, in Cleveland, Ohio, Lovell achieved Eagle Scout as a member of the Boy Scouts and studied engineering as part of the US Navy’s “Flying Midshipman” program at the University of Wisconsin in Madison from 1946 to 1948. Four years later, he was commissioned as an ensign and graduated with a Bachelor of Science degree from the Naval Academy in Annapolis, Maryland.

Lovell reported for flight training at Naval Air Station Pensacola in October 1952, and he was designated a naval aviator on February 1, 1954. He served at Moffett Field in Northern California and logged 107 deck landings during a deployment aboard the aircraft carrier USS Shangri-La.

In July 1958, Lovell graduated at the top of the class at the Naval Air Test Center (today, the US Naval Test Pilot School) at Naval Air Station Patuxent River in Maryland. He was one of 110 candidates to be considered for NASA’s original Mercury 7 astronauts but was turned away due to a temporary medical concern. Instead, Lovell became the program manager for the McDonnell Douglas F-4 Phantom II supersonic jet.

In 1962, Lovell was serving as a flight instructor and safety engineering officer at Naval Air Station Oceana in Virginia Beach when he was chosen for the second class of NASA astronauts, the “Next Nine.”

In addition to his prime crew assignments, Lovell also served on the backup crews for the Gemini 4, Gemini 9, and Apollo 11 missions, the latter supporting Neil Armstrong as backup commander. He also served on a panel studying what could be done in case of an in-flight fire after a fire on the launch pad claimed the lives of the Apollo 1 crew in 1967.

After the Apollo 13 mission, Lovell was named the deputy director of science and applications at NASA’s Manned Spacecraft Center (today, Johnson Space Center) before retiring from both the space agency and Navy on March 1, 1973. Lovell became chief executive officer of Bay-Houston Towing Company in 1975 and then president of Fisk Telephone Systems in 1977.

On January 1, 1981, Lovell joined Centel Corporation as group vice president for business communications systems and, 10 years later, retired as executive vice president and a member of the company’s board of directors.

For 11 years, from 1967 to 1978, Lovell served as a consultant and then chairman of the Physical Fitness Council (today, the President’s Council on Sports, Fitness and Nutrition). He was a member of the board for several organizations, including Federal Signal Corporation in Chicago from 1984 to 2003 and the Astronautics Corporation of America in Milwaukee from 1990 to 1999. He was also chairman of the Astronaut Scholarship Foundation from 1997 to 2005.

Appearances and awards

From 1999 to 2006, Lovell helped run “Lovell’s of Lake Forest,” a restaurant that he and his family opened in Illinois. (The restaurant was then sold to Jay, Lovell’s son, but ultimately closed in 2015.)

In 1994, Lovell worked with Jeffrey Kluger to publish Lost Moon: The Perilous Voyage of Apollo 13, which was later retitled Apollo 13 after serving as the basis for the Ron Howard movie.

In addition to being played by Hanks and having a cameo in Apollo 13, Lovell was also portrayed by Tim Daly in the 1998 HBO miniseries From the Earth to the Moon and Pablo Schreiber in the 2018 Neil Armstrong biopic First Man. Lovell also made a cameo appearance in the 1976 movie The Man Who Fell to Earth.

For his service to the US space program, Lovell was awarded the NASA Distinguished Service and Exceptional Service medals; the Congressional Space Medal of Honor, and Presidential Medal of Freedom. As a member of the Gemini 7, Gemini 12, and Apollo 8 crews, Lovell was bestowed the Harmon International Trophy three times and, with his Apollo 8 crewmates, the Robert J. Collier and Dr. Robert H. Goddard Memorial trophies and was named Time Magazine’s Man of the Year for 1968.

Lovell was inducted into the International Space Hall of Fame in 1982, the US Astronaut Hall of Fame in 1993, and National Aviation Hall of Fame in 1998.

A crater on the far side of the moon was named for Lovell in 1970. In 2009, he was awarded a piece of the moon as part of NASA’s Ambassador of Exploration Award, which Lovell placed on display at the Patuxent River Naval Air Museum in Lexington Park, Maryland.

Lovell’s legacy

In 2005, Lovell donated his personal collection of NASA memorabilia to the Adler Planetarium in Chicago, where it is on display in the “Mission Moon” exhibition.

With Lovell’s death, only five out of the 24 people who flew to the moon during the Apollo program remain living (Buzz Aldrin, 95; Fred Haise, 91; David Scott, 93; Charlie Duke, 89; and Harrison Schmitt, 90).

Lovell is survived by his children, Barbara Harrison, James Lovell III, Susan Lovell, and Jeffrey Lovell; 11 grandchildren; and nine great-grandchildren. Lovell was preceded in death by his wife Marilyn Lovell and parents James Lovell, Sr, and Blanche Lovell (Masek).

“We are enormously proud of his amazing life and career accomplishments, highlighted by his legendary leadership in pioneering human space flight,” said Lovell’s family in a statement. “But, to all of us, he was dad, granddad and the leader of our family. Most importantly, he was our hero. We will miss his unshakeable optimism, his sense of humor and the way he made each of us feel we could do the impossible. He was truly one of a kind.”

A memorial service and burial will be held at the Naval Academy in Annapolis on a date still to be announced.
