“Naming space as a warfighting domain was kind of forbidden, but that’s changed.”

The launch of a classified Russian military satellite last week deployed a payload that US government officials say is likely a space weapon.

In a series of statements, US officials said the new military satellite, named Kosmos 2576, appears to be similar to two previous “inspector” spacecraft launched by Russia in 2019 and 2022.

“Just last week, on May 16, Russia launched a satellite into low-Earth orbit that the United States assesses is likely a counter-space weapon presumably capable of attacking other satellites in low-Earth orbit,” said Robert Wood, the deputy US ambassador to the United Nations. “Russia deployed this new counter-space weapon into the same orbit as a US government satellite.”

Kosmos 2576 is flying in the same orbital plane as a National Reconnaissance Office (NRO) spy satellite, meaning it can regularly approach the top-secret US reconnaissance platform. The launch of Kosmos 2576 from Russia’s Plesetsk Cosmodrome on a Soyuz rocket was precisely timed to happen when the Earth’s rotation brought the launch site underneath the orbital path of the NRO spy satellite, officially designated USA 314.

The Soyuz rocket’s Fregat upper stage released Kosmos 2576 into an orbit roughly 275 miles (445 km) above Earth at an inclination of 97.25 degrees to the equator.

Conventional but concerning

So far, Kosmos 2576 is nowhere near USA 314, a bus-size spacecraft believed to carry a powerful Earth-facing telescope to capture high-resolution images for use by US intelligence agencies. This type of spacecraft is publicly known as a KH-11, or Keyhole-class, satellite, but its design and capabilities are top-secret.

It’s no surprise that the Russian military wants to get a close look in hopes of learning more about the US government’s most closely held secrets about what it does in orbit. Russian satellites have also flown near Western communications satellites in geostationary orbit, likely in an attempt to eavesdrop on radio transmissions.

Russia’s deputy foreign minister, Sergei Ryabkov, dismissed the US government’s assessment about the purpose of Kosmos 2576 as “fake news.” However, in the last few years, Russia has steered satellites into orbits intersecting with the paths of US spy platforms, and demonstrated it can take out an enemy satellite using a range of methods.

The current orbit of Kosmos 2576 will only occasionally bring it within a few hundred kilometers of the USA 314, according to Jonathan McDowell, an astrophysicist and expert tracker of spaceflight events. However, analysts expect additional maneuvers to raise the altitude Kosmos 2576 and put it into position for closer passes. This is what happened with a pair of Russian satellites launched in 2019 and 2022.

These two previous Russian satellites—Kosmos 2542 and Kosmos 2558— continually flew within a few dozen kilometers of two other NRO satellites—USA 245 and USA 326—in low-Earth orbit. In a post on the social media platform X, McDowell wrote that the Russian military craft “shadowed US satellites at a large distance but have not interfered with them.”

Because of this, McDowell wrote that he is “highly skeptical” that Kosmos 2576 is an anti-satellite weapon.

But one of these Russian satellites, Kosmos 2542, released a smaller sub-satellite, designated Kosmos 2543, which made its own passes near the USA 245 spacecraft, a KH-11 imaging satellite similar to USA 314. At one point, satellite trackers noticed USA 245 made a slight change to orbit. Its Russian pursuer later made a similar orbit adjustment to keep up.

In 2020, Kosmos 2543 backed off from USA 245. Once well away from the NRO satellite, Kosmos 2543 ejected a mysterious projectile into space at a speed fast enough to damage any target in its sights.

At the time, US Space Command called the event a “non-destructive test of a space-based anti-satellite weapon.” The projectile fired from Kosmos 2543 at a relative velocity of some 400 mph (700 km per hour), according to McDowell’s analysis of publicly available satellite tracking data.

The US military has identified China as its most significant strategic adversary in the coming decades. Most aspects of Russia’s space program are in decline, but it still boasts formidable anti-satellite capabilities. Russia intentionally destroyed one of its retired satellites in orbit with a ground-based missile in 2021. The Russian military has also deployed several Peresvet laser units capable of disabling a satellite in orbit. A Russian cyberattack at the start of the invasion of Ukraine in 2022 knocked a commercial satellite communications network offline.

Most recently, US government officials have claimed Russia is developing a nuclear anti-satellite weapon. Russian officials also denied this. But Russia vetoed a UN Security Council resolution last month reiterating language from the 1967 Outer Space Treaty banning weapons of mass destruction in orbit.

The US military has its own fleet of inspector satellites in orbit to track what other nations are doing in space. The Space Force’s development of any offensive military capability in space is classified.

“The space domain is much more challenging today than it was a number a number of years ago,” said Air Force Gen. Charles “CQ” Brown, chairman of the joint chiefs of staff, in an event Wednesday hosted by the Atlantic Council. “We looked at it as a very benign environment, where you didn’t have to worry about conflicts in space. As a matter of fact, naming space as a warfighting domain was kind of forbidden, but that’s changed, and it’s been changed based what our adversaries are doing in space.”

“We don’t want to have our satellites … be challenged,” Brown said. “So we want to make sure that we have the capabilities to defend ourselves, no matter what domain we’re in, whether it’s in the space domain, air, land, or maritime. That’s where our focus is as a military, in making sure we’re investing to provide the capabilities and expertise to do that.”

Blue Origin resumes human flights to suborbital space, but it wasn’t perfect

“I lied” —

More than 60 years after he was denied an opportunity to become America’s first Black astronaut, Ed Dwight finally traveled into space Sunday with five other passengers on a 10-minute flight inside a Blue Origin capsule.

Dwight, a retired Air Force captain and test pilot, had a chance to become the first African American astronaut. He was one of 26 pilots the Air Force recommended to NASA for the third class of astronauts in 1963, but the agency didn’t select him. It took another 20 years for America’s first Black astronaut, Guion Bluford, to fly in space in 1983.

“Everything they did, I did, and I did it well,” Dwight said in a video released by Blue Origin. “If politics had changed, I would have gone to space in some kind of capacity.”

At the age of 90, Dwight finally entered the record books Sunday, becoming the oldest person to reach space, displacing the previous record-holder, actor William Shatner, who flew on a similar Blue Origin launch to the edge of space in 2021.

“I thought I didn’t need it in my life,” Dwight said after Sunday’s fight. “But I lied!”

Since retiring from the Air Force, Dwight became an accomplished sculptor. His works, which focus on Black history, are installed at memorials and monuments across the country.

“The transitions, the separations and stuff were a little bit more dynamic than I thought,” Dwight said in remarks after Sunday’s flight. “But that’s how it’s supposed to be. It makes your mind wonder, ‘Is something wrong?’ But no, it was absolutely terrific and the view … absolutely fantastic. This was a life-changing experience. Everybody needs to do this.”

Dwight and his five co-passengers lifted off from Blue Origin’s remote launch site in West Texas at 9: 35 am CDT (14: 35 UTC). Strapped into reclining seats inside a pressurized capsule, the passengers rode Blue Origin’s New Shepard rocket into the uppermost layers of the atmosphere. After burning its main engine more than two minutes, the rocket released the crew capsule and continued coasting upward to an apogee, or high point, of nearly 66 miles (107 kilometers), just above the internationally recognized boundary of space.

This was the seventh time Blue Origin, the space company owned by billionaire Jeff Bezos, has flown people to suborbital space, and the 25th flight overall of the company’s fleet of New Shepard rockets. It was the first time Blue Origin has launched people in nearly two years, resuming suborbital service after a rocket failure on an uncrewed research flight in September 2022. In December, Blue Origin launched another uncrewed suborbital research mission to set the stage for the resumption of human missions Sunday.

Joining Dwight on Blue Origin’s capsule were investor Mason Angel, French businessman Sylvain Chiron, software engineer Kenneth Hess, adventurer Carol Schaller, and Gopi Thotakura, an Indian pilot and entrepreneur. Dwight’s ticket with Blue Origin was sponsored by Space for Humanity, a nonprofit that seeks to expand access to space for all people, and the other five participants were paying passengers.

After cutoff of the New Shepard rocket engine, the passengers had a few minutes to unfasten their seatbelts and float around the cabin while taking in the view of Earth. They returned to their seats as the capsule descended back into the atmosphere. The reusable New Shepard booster reignited its main engine for a propulsive landing back in Texas, while the crew capsule deployed parachutes to slow for touchdown a few miles away.

Two of three

However, one of the three main parachutes did not fully unfurl as the capsule drifted back to the ground. The capsule is designed to safely land with two chutes, a capability Blue Origin demonstrated on a test flight in 2016.

“It looks like we do have two parachutes that have full inflation, the third is not quite fully inflated,” said Ariane Cornell, a Blue Origin official hosting the company’s live webcast Sunday. “Landing with two parachutes is perfectly OK for this system.”

Family members and Blue Origin personnel greeted the passengers as they exited the capsule. All six appeared to be in good spirits and good health.

Although it had no obvious ill effects on the crew or the spacecraft, Blue Origin engineers will investigate the malfunction to determine what went wrong. The capsule’s three main parachutes were supplied to Blue Origin by Airborne Systems, which manufactures parachutes for every US human-rated spacecraft.

Airborne also provides parachutes for SpaceX’s Dragon spacecraft, Boeing’s Starliner, and NASA’s Orion capsule. Those parachutes have different designs and sizes than the chutes used on Blue Origin’s capsule, but it wasn’t immediately clear if there might be any crossover concerns on other programs stemming from the malfunction on Sunday’s flight.

The Federal Aviation Administration, the regulatory agency that oversees US commercial space missions, said in a statement it did not consider the parachute issue a mishap. This statement suggests the incident will not trigger a mishap investigation that would require FAA oversight.

Before the 2022 launch failure, Blue Origin’s New Shepard program achieved a cadence, on average, of roughly one flight every two months. Virgin Galactic, the space tourism company founded by Richard Branson, ramped up the flight rate of its suborbital SpaceShipTwo spaceplane over the last year as Blue Origin’s rocket remained grounded.

But Virgin Galactic is about to halt operations of its own spaceship following one more flight with passengers next month. The company says it decided to suspend flights of the VSS Unity rocket plane to focus its resources on developing a fleet of larger air-launched spaceships that are easier to reuse.

This means Blue Origin, assuming it can regain or build on the cadence it demonstrated in 2021 and 2022, will be the only company serving the suborbital space tourism and research market for at least the next couple of years.

We take a stab at decoding SpaceX’s ever-changing plans for Starship in Florida

Enlarge / SpaceX’s Starship tower (left) at Launch Complex 39A dwarfs the launch pad for the Falcon 9 rocket (right).

There are a couple of ways to read the announcement from the Federal Aviation Administration that it’s kicking off a new environmental review of SpaceX’s plan to launch the most powerful rocket in the world from Florida.

The FAA said on May 10 that it plans to develop an Environmental Impact Statement (EIS) for SpaceX’s proposal to launch Starships from NASA’s Kennedy Space Center in Florida. The FAA ordered this review after SpaceX updated the regulatory agency on the projected Starship launch rate and the design of the ground infrastructure needed at Launch Complex 39A (LC-39A), the historic launch pad once used for Apollo and Space Shuttle missions.

Dual environmental reviews

At the same time, the US Space Force is overseeing a similar EIS for SpaceX’s proposal to take over a launch pad at Cape Canaveral Space Force Station, a few miles south of LC-39A. This launch pad, designated Space Launch Complex 37 (SLC-37), is available for use after United Launch Alliance’s last Delta rocket lifted off there in April.

On the one hand, these environmental reviews often take a while and could cloud Elon Musk’s goal of having Starship launch sites in Florida ready for service by the end of 2025. “A couple of years would not be a surprise,” said George Nield, an aerospace industry consultant and former head of the FAA’s Office of Commercial Space Transportation.

Another way to look at the recent FAA and Space Force announcements of pending environmental reviews is that SpaceX finally appears to be cementing its plans to launch Starship from Florida. These plans have changed quite a bit in the last five years.

The environmental reviews will culminate in a decision on whether to approve SpaceX’s proposals for Starship launches at LC-39A and SLC-37. The FAA will then go through a separate licensing process, similar to the framework used to license the first three Starship test launches from South Texas.

NASA has contracts with SpaceX worth more than $4 billion to develop a human-rated version of Starship to land astronauts on the Moon on the first two Artemis lunar landing flights later this decade. To do that, SpaceX must stage a fuel depot in low-Earth orbit to refuel the Starship lunar lander before it heads for the Moon. It will take a series of Starship tanker flights—perhaps 10 to 15—to fill the depot with cryogenic propellants.

Launching that many Starships over the course of a month or two will require SpaceX to alternate between at least two launch pads. NASA and SpaceX officials say the best way to do this is by launching Starships from one pad in Texas and another in Florida.

Earlier this week, Ars spoke with Lisa Watson-Morgan, who manages NASA’s human-rated lunar lander program. She was at Kennedy Space Center this week for briefings on the Starship lander and a competing lander from Blue Origin. One of the topics, she said, was the FAA’s new environmental review before Starship can launch from LC-39A.

“I would say we’re doing all we can to pull the schedule to where it needs to be, and we are working with SpaceX to make sure that their timeline, the EIS timeline, and NASA’s all work in parallel as much as we can to achieve our objectives,” she said. “When you’re writing it down on paper just as it is, it looks like there could be some tight areas, but I would say we’re collectively working through it.”

Officially, SpaceX plans to perform a dress rehearsal for the Starship lunar landing in late 2025. This will be a full demonstration, with refueling missions, an uncrewed landing of Starship on the lunar surface, then a takeoff from the Moon, before NASA commits to putting people on Starship on the Artemis III mission, currently slated for September 2026.

So you can see that schedules are already tight for the Starship lunar landing demonstration if SpaceX activates launch pads in Florida late next year.

Rocket Report: Starship stacked; Georgia shuts the door on Spaceport Camden

On Wednesday, SpaceX fully stacked the Super Heavy booster and Starship upper stage for the mega-rocket's next test flight from South Texas.

Enlarge / On Wednesday, SpaceX fully stacked the Super Heavy booster and Starship upper stage for the mega-rocket’s next test flight from South Texas.

Welcome to Edition 6.44 of the Rocket Report! Kathy Lueders, general manager of SpaceX’s Starbase launch facility, says the company expects to receive an FAA launch license for the next Starship test flight shortly after Memorial Day. It looks like this rocket could fly in late May or early June, about two-and-a-half months after the previous Starship test flight. This is an improvement over the previous intervals of seven months and four months between Starship flights.

Blue Origin launch on tap this weekend. Blue Origin plans to launch its first human spaceflight mission in nearly two years on Sunday. This flight will launch six passengers on a flight to suborbital space more than 60 miles (100 km) over West Texas. Blue Origin, Jeff Bezos’s space company, has not flown people to space since a New Shepard rocket failure on an uncrewed research flight in September 2022. The company successfully launched New Shepard on another uncrewed suborbital mission in December.

Historic flight … This will be the 25th flight of Blue Origin’s New Shepard rocket, and the seventh human spaceflight mission on New Shepard. Before Blue Origin’s rocket failure in 2022, the company was reaching a flight cadence of about one launch every two months, on average. The flight rate has diminished since then. Sunday’s flight is important not only because it marks the resumption of launches for Blue Origin’s suborbital human spaceflight business, but also because its six-person crew includes an aviation pioneer. Ed Dwight, 90, almost became the first Black astronaut in 1963. Dwight, a retired Air Force captain, piloted military fighter jets and graduated test pilot school, following a familiar career track as many of the early astronauts. He was on a short list of astronaut candidates the Air Force provided NASA, but the space agency didn’t include him. Dwight will become the oldest person to ever fly in space.

Spaceport Camden is officially no more. With the stroke of a pen, Georgia Governor Brian Kemp signed a bill that dissolved the Camden County Spaceport Authority, Action News Jax reported. This news follows a referendum in March 2022 where more than 70 percent of voters rejected a plan to buy land for the spaceport on the Georgia coastline between Savannah and Jacksonville, Florida. County officials still tried to move forward with the spaceport initiative after the failed referendum, but Georgia’s Supreme Court ruled in February that the county had to abide by the voters’ wishes.

$12 million for what?… The government of Camden County, with a population of about 55,000 people spent $12 million on the Spaceport Camden concept over the course of a decade. The goal of the spaceport authority was to lure small launch companies to the region, but no major launches ever took place from Camden County. State Rep. Steven Sainz, who sponsored the bill eliminating the spaceport authority, said in a statement that the legislation “reflects the community’s choice and opens a path for future collaborations in economic initiatives that are more aligned with local needs.” (submitted by zapman987)

Polaris Spaceplanes moves on to bigger things. German startup Polaris Spaceplanes says it is progressing with construction of its MIRA II and MIRA III spaceplane prototypes after MIRA, a subscale test vehicle, was damaged earlier this year, European Spaceflight reports. The MIRA demonstration vehicle crash-landed on a test flight in February. The incident occurred on takeoff at an airfield in Germany before the vehicle could ignite its linear aerospace engine in flight. The remote-controlled MIRA prototype measured about 4.25 meters long. Polaris announced on April 30 that will not repair MIRA and will instead move forward with the construction of a pair of larger vehicles.

Nearly 16 months without a launch … The MIRA II and MIRA III vehicles will be 5 meters long and will be powered by Polaris’s AS-1 aerospike engines, along with jet engines to power the craft before and after in-flight tests of the rocket engine. Aerospike engines are rocket engines that are designed to operate efficiently at all altitudes. The MIRA test vehicles are precursors to AURORA, a multipurpose spaceplane and hypersonic transporter Polaris says will be capable of delivering up to 1,000 kilograms of payload to low-Earth orbit.

Welcome to Edition 6.42 of the Rocket Report! Several major missions are set for launch in the next few months. These include the first crew flight on Boeing’s Starliner spacecraft, set for liftoff on May 6, and the next test flight of SpaceX’s Starship rocket, which could happen before the end of May. Perhaps as soon as early summer, SpaceX could launch the Polaris Dawn mission with four private astronauts, who will perform the first fully commercial spacewalk in orbit. In June or July, Europe’s new Ariane 6 rocket is slated to launch for the first time. Rest assured, Ars will have it all covered.

German rocket arrives at Scottish spaceport. Rocket Factory Augsburg has delivered a booster for its privately developed RFA One rocket to SaxaVord Spaceport in Scotland, the company announced on X. The first stage for the RFA One rocket was installed on its launch pad at SaxaVord to undergo preparations for a static fire test. The booster arrived at the Scottish launch site with five of its kerosene-fueled Helix engines. The remaining four Helix engines, for a total of nine, will be fitted to the RFA One booster at SaxaVord, the company said.

Aiming to fly this year… RFA hopes to launch its first orbital-class rocket by the end of 2024. The UK’s Civil Aviation Authority last month granted a range license to SaxaVord Spaceport to allow the spaceport operator to control the sea and airspace during a launch. RFA is primarily privately funded but has won financial support from the European Space Agency, the UK Space Agency, and the German space agency, known as DLR. The RFA One rocket will have three stages, stand nearly 100 feet (30 meters) tall, and can carry nearly 2,900 pounds (1,300 kilograms) of payload into a polar Sun-synchronous orbit.

Arianespace wins ESA launch contract. The European Space Agency has awarded Arianespace a contract to launch a joint European-Chinese space science satellite in late 2025, European Spaceflight reports. The Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) is a 4,850-pound (2,200-kilogram) spacecraft that will study Earth’s magnetic environment on a global scale. The aim of the mission is to build a more complete understanding of the Sun-Earth connection. On Tuesday, ESA officially signed a contract for Arianespace to launch SMILE aboard a Vega C rocket, which is built by the Italian rocket-maker Avio.

But it may not keep it … In late 2023, ESA member states agreed to allow Avio to market and manage the launch of Vega C flights independent of Arianespace. When the deal was initially struck, 17 flights were contracted through Arianespace to be launched aboard Vega vehicles. While these missions are still managed by Arianespace, Avio is working with the launch provider to strike a deal that would allow the Italian rocket builder to assume the management of all Vega flights. The Vega C rocket has been grounded since a launch failure in 2022 forced Avio to redesign the nozzle of the rocket’s solid-fueled second-stage motor. Vega C is scheduled to return to flight before the end of 2024. (submitted by Ken the Bin)

Update on ABL’s second launch. ABL Space Systems expected to launch its second light-class RS1 rocket earlier this year, but the company encountered an anomaly during ground testing at the launch site in Alaska, according to Aria Alamalhodaei of TechCrunch. Kevin Sagis, ABL’s chief engineer, said there is “no significant delay” in the launch of the second RS1 rocket, but the company has not announced a firm schedule. “During ground testing designed to screen the vehicle for flight, an issue presented that caused us to roll back to the hangar,” Sagis said, according to Alamalhodaei. “We have since resolved and dispositioned the issue. There was no loss of hardware and we have validated vehicle health back out on the pad. We are continuing with preparations for static fire and launch.”

Nearly 16 months without a launch … ABL’s first RS1 test flight in January 2023 ended seconds after liftoff with the premature shutdown of its liquid-fueled engines. The rocket crashed back onto its launch pad in Alaska. An investigation revealed a fire in the aft end of the RS1 booster burned through wiring harnesses, causing the rocket to lose power and shut off its engines. Engineers believe the rocket’s mobile launch mount was too small, placing the rocket too close to the ground when it ignited its engines. This caused the hot engine exhaust to recirculate under the rocket and led to a fire in the engine compartment as it took off.

SpaceX’s most-flown reusable rocket will go for its 20th launch tonight

For the first time, SpaceX will launch one of its reusable Falcon 9 boosters for a 20th time Friday night on a flight to deliver 23 more Starlink Internet satellites to orbit.

This milestone mission is scheduled to lift off at 9: 22 pm EDT Friday (01: 22 UTC Saturday) from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station, Florida. Forecasters from the US Space Force predict “excellent” weather for the primetime launch.

Falcon 9 will blaze a familiar trail into space, following the same profile as dozens of past Starlink missions.

The rocket’s first-stage booster will shut off its nine kerosene-fueled Merlin engines about two-and-a-half minutes into the flight, reaching a top speed of more than 5,000 mph (8,000 km per hour). The first stage will detach from the Falcon 9’s upper stage, which will continue firing into orbit. The 15-story-tall Falcon 9 booster, meanwhile, will follow an arcing trajectory before braking for a vertical landing on a drone ship floating in the Atlantic Ocean near the Bahamas.

The 23 flat-packed Starlink spacecraft will deploy from the upper stage a little more than an hour after liftoff, bringing the total number of Starlinks in low-Earth orbit to more than 5,800 spacecraft.

A hunger for launch

Pretty much every day, SpaceX is either launching a rocket or rolling one out of the hangar to the launch pad. At this pace, SpaceX is redefining what is routine in the space industry, but the rapid-fire launch rate also means the company is continually breaking records, mostly its own.

Friday night’s launch will break another one of those records. This first-stage booster, designated by the tail number B1062, has flown 19 times since its first flight in November 2020. The booster will now be the first in SpaceX’s inventory to go for a 20th flight, breaking a tie with three other rockets as the company’s fleet leader.

When SpaceX debuted the latest version of its Falcon 9 rocket, the Falcon 9 Block 5, officials said the reusable first stage could fly 10 times with minimal refurbishment and perhaps additional flights with a more extensive overhaul. Now, SpaceX is certifying Falcon 9 boosters for 40 flights.

This particular rocket has not undergone any extended maintenance or long-term grounding. It has flown an average of once every two months since debuting three-and-a-half years ago. So the 20-flight milestone SpaceX will achieve Friday night means this rocket has doubled its original design life and, at the same time, has reached the halfway point of its extended service life.

In its career, this booster has launched eight people and 530 spacecraft, mostly Starlinks. The rocket’s first two flights launched GPS navigation satellites for the US military, then it launched two commercial human spaceflight missions with Dragon crew capsules. These were the all-private Inspiration4 mission and Axiom Mission 1, the first fully commercial crew flight to the International Space Station.

Remarkably, this will be the sixth Falcon 9 launch in less than eight days, more flights than SpaceX’s main US rival, United Launch Alliance, has launched in 17 months.

It will be the 38th Falcon 9 launch of the year and the 111th flight of a Falcon 9 or Falcon Heavy rocket—the 114th launch by SpaceX overall—in the last 365 days. More than a third of SpaceX’s Falcon 9 or Falcon Heavy missions, a number that will stand at 332 after Friday night’s flight, have launched in the past year.

This month, for the first time, SpaceX demonstrated it could launch two Falcon 9 rockets in less than five days from the company’s launch pad at Vandenberg Space Force Base, California. SpaceX has also cut the turnaround time between Falcon 9 rockets at Launch Complex 39A at NASA’s Kennedy Space Center. The company’s most-used launch pad, SLC-40, can handle two Falcon 9 flights in less than four days.

It’s not just launch pad turnaround. SpaceX uses its drone ships—two based in Florida and one in California—for most Falcon 9 landings. In order to meet the appetite for Falcon 9 launches, SpaceX is getting rockets back to port and re-deploying drone ships back to sea at a faster rate.

United Launch Alliance

The final flight of United Launch Alliance’s Delta IV Heavy rocket took off Tuesday from Cape Canaveral, Florida, with a classified spy satellite for the National Reconnaissance Office.

The Delta IV Heavy, one of the world’s most powerful rockets, launched for the 16th and final time Tuesday. It was the 45th and last flight of a Delta IV launcher and the final rocket named Delta to ever launch, ending a string of 389 missions dating back to 1960.

United Launch Alliance (ULA) tried to launch this rocket on March 28 but aborted the countdown about four minutes prior to liftoff due to trouble with nitrogen pumps at an off-site facility at Cape Canaveral. The nitrogen is necessary for purging parts inside the Delta IV rocket before launch, reducing the risk of a fire or explosion during the countdown.

The pumps, operated by Air Liquide, are part of a network that distributes nitrogen to different launch pads at the Florida spaceport. The nitrogen network has caused problems before, most notably during the first launch campaign for NASA’s Space Launch System rocket in 2022. Air Liquide did not respond to questions from Ars.

A flawless liftoff

With a solution in place, ULA gave the go-ahead for another launch attempt Tuesday. After a smooth countdown, the final Delta IV Heavy lifted off from Cape Canaveral Space Force Station at 12: 53 pm EDT (16: 53 UTC).

Three hydrogen-fueled RS-68A engines made by Aerojet Rocketdyne flashed to life in the final seconds before launch and throttled up to produce more than 2 million pounds of thrust. The ignition sequence was accompanied by a dramatic hydrogen fireball, a hallmark of Delta IV Heavy launches, that singed the bottom of the 235-foot-tall (71.6-meter) rocket, turning a patch of its orange insulation black. Then, 12 hold-down bolts fired and freed the Delta IV Heavy for its climb into space with a top-secret payload for the US government’s spy satellite agency.

Heading east from Florida’s Space Coast, the Delta IV Heavy appeared to perform well in the early phases of its mission. After fading from view from ground-based cameras, the rocket’s two liquid-fueled side boosters jettisoned around four minutes into the flight, a moment captured by onboard video cameras. The core stage engine increased power to fire for a couple more minutes. Nearly six minutes after liftoff, the core stage was released, and the Delta IV upper stage took over for a series of burns with its RL10 engine.

At that point, ULA cut the public video and audio feeds from the launch control center, and the mission flew into a news blackout. The final portions of rocket launches carrying National Reconnaissance Office (NRO) satellites are usually performed in secret.

In all likelihood, the Delta IV Heavy’s upper stage was expected to fire its engine at least three times to place the classified NRO satellite into a circular geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator. In this orbit, the spacecraft will move in lock-step with the planet’s rotation, giving the NRO’s newest spy satellite constant coverage over a portion of the Earth.

It will take about six hours for the rocket’s upper stage to deploy its payload into this high-altitude orbit and only then will ULA and the NRO declare the launch a success.

Eavesdropping from space

While the payload is classified, experts can glean a few insights from the circumstances of its launch. Only the largest NRO spy satellites require a launch on a Delta IV Heavy, and the payload on this mission is “almost certainly” a type of satellite known publicly as an “Advanced Orion” or “Mentor” spacecraft, according to Marco Langbroek, an expert Dutch satellite tracker.

The Advanced Orion satellites require the combination of the Delta IV Heavy rocket’s lift capability, long-duration upper stage, and huge, 65-foot-long (19.8-meter) trisector payload fairing, the largest payload enclosure of any operational rocket. In 2010, Bruce Carlson, then-director of the NRO, referred to the Advanced Orion platform as the “largest satellite in the world.”

When viewed from Earth, these satellites shine with the brightness of an eighth-magnitude star, making them easily visible with small binoculars despite their distant orbits, according to Ted Molczan, a skywatcher who tracks satellite activity.

“The satellites feature a very large parabolic unfoldable mesh antenna, with estimates of the size of this antenna ranging from 20 to 100 (!) meters,” Langbroek writes on his website, citing information leaked by Edward Snowden.

The purpose of these Advanced Orion satellites, each with mesh antennas that unfurl to a diameter of up to 330 feet (100 meters), is to listen in on communications and radio transmissions from US adversaries, and perhaps allies. Six previous Delta IV Heavy missions also likely launched Advanced Orion or Mentor satellites, giving the NRO a global web of listening posts parked high above the planet.

With the last Delta IV Heavy off the launch pad, ULA has achieved a goal of its corporate strategy sent into motion a decade ago, when the company decided to retire the Delta IV and Atlas V rockets in favor of a new-generation rocket named Vulcan. The first Vulcan rocket successfully launched in January, so the last few months have been a time of transition for ULA, a 50-50 joint venture owned by Boeing and Lockheed Martin.

“This is such an amazing piece of technology: 23 stories tall, half a million gallons of propellant, two and a quarter million pounds of thrust, and the most metal of all rockets, setting itself on fire before it goes to space,” Bruno said of the Delta IV Heavy before its final launch. “Retiring it is (key to) the future, moving to Vulcan, a less expensive, higher-performance rocket. But it’s still sad.”

“Everything that Delta has done … is being done better on Vulcan, so this is a great evolutionary step,” said Bill Cullen, ULA’s launch systems director. “It is bittersweet to see the last one, but there are great things ahead.”

Welcome to Edition 6.38 of the Rocket Report! Ed Dwight was close to joining NASA’s astronaut corps more than 60 years ago. With an aeronautical engineering degree and experience as an Air Force test pilot, Dwight met the qualifications to become an astronaut. He was one of 26 test pilots the Air Force recommended to NASA for the third class of astronauts in 1963, but he wasn’t selected. Now, the man who would have become the first Black astronaut will finally get a chance to fly to space.

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.

Ed Dwight named to Blue Origin’s next human flight. Blue Origin, Jeff Bezos’ space company, announced Thursday that 90-year-old Ed Dwight, who almost became the first Black astronaut in 1963, will be one of six people to fly to suborbital space on the company’s next New Shepard flight. Dwight, a retired Air Force captain, piloted military fighter jets and graduated test pilot school, following a familiar career track as many of the early astronauts. He was on a short list of astronaut candidates the Air Force provided NASA, but the space agency didn’t include him. It took 20 more years for the first Black American to fly to space. Dwight’s ticket with Blue Origin is sponsored by Space for Humanity, a nonprofit that seeks to expand access to space for all people. Five paying passengers will join Dwight for the roughly 10-minute up-and-down flight to the edge of space over West Texas. Kudos to Space for Humanity and Blue Origin for making this happen.

Return to flight … This mission, named NS-25, will be the first time Blue Origin flies with human passengers since August 2022. Blue Origin hasn’t announced a launch date yet for NS-25. On an uncrewed launch the following month, an engine failure destroyed a New Shepard booster and grounded Blue Origin’s suborbital rocket program for more than 15 months. New Shepard returned to flight December 19 on another research flight, again without anyone onboard. As the mission name suggests, this will be the 25th flight of a New Shepard rocket and the seventh flight with people. Blue Origin has a history of flying aviation pioneers and celebrities. On the first human flight with New Shepard in 2021, the passengers included company founder Jeff Bezos and famed female aviator Wally Funk. (submitted by EllPeaTea)

Revisit Astra’s 2020 rocket explosion. In March 2020, as the world was under the grip of COVID, Astra blew up a rocket in remote Alaska and didn’t want anyone to see it. New video published by TechCrunch shows Astra’s Rocket 3 vehicle exploding on its launch pad. This was one of several setbacks that have brought the startup to its knees. The explosion, which occurred at Alaska’s Pacific Spaceport Complex, was simply reported as an “anomaly” at the time, an industry term for pretty much any issue that deviates from the expected outcome, TechCrunch reports. Satellite imagery of the launch site showed burn scars, suggesting an explosion, but the footage published this week confirms the reality of the event. This was Astra’s first orbital-class rocket, and it blew up during a fueling rehearsal.

A sign of things to come … Astra eventually flew its Rocket 3 small satellite launcher seven times, but only two of the flights actually reached orbit. This prompted Astra to abandon its Rocket 3 program and focus on developing a larger rocket, Rocket 4. But the future of this new rocket is in doubt. Astra’s co-founders are taking the company private after its market value and stock price tanked, and it’s not clear where the company will go from here. (submitted by Ken the Bin)

Russia’s plan to “restore” its launch industry. Yuri Borisov, chief of the Russian space agency Roscosmos, has outlined a strategy for Russia to regain a dominant position in the global launch market, Ars reports. This will include the development of a partially reusable replacement for the Soyuz rocket called Amur-CNG. The country’s spaceflight enterprise is also working on “ultralight” boosters that will incorporate an element of reusability. In an interview posted on the Roscosmos website, Borisov said he hopes Russia will have a “completely new fleet of space vehicles” by the 2028-2029 timeframe. Russia has previously discussed plans to develop the Amur rocket (the CNG refers to the propellant, liquified methane). The multi-engine vehicle looks somewhat similar to SpaceX’s Falcon 9 rocket in that preliminary designs incorporated landing legs and grid fins to enable a powered first-stage landing.

Reason to doubt … Russia’s launch industry was a global leader a couple of decades ago when prices were cheap relative to Western rockets. But the heavy-lift Proton rocket is nearing retirement after concerns about its reliability, and the still-reliable Soyuz is now excluded from the global market after Russia’s invasion of Ukraine. In the 2000s and 2010s, Russia’s position in the market was supplanted by the European Ariane 5 rocket and then SpaceX’s Falcon 9. Roscosmos originally announced the medium-lift Amur rocket program in 2020 for a maiden flight in 2026. Since then, the rocket has encountered a nearly year-for-year delay in its first test launch. I’ll believe it when I see it. The only new, large rocket Russia has developed in nearly 40 years, the expendable Angara A5, is still launching dummy payloads on test flights a decade after its debut.

The Delta IV Heavy, a rocket whose time has come and gone, will fly once more

This is the rocket that literally lights itself on fire before it heads to space. It’s the world’s largest rocket entirely fueled by liquid hydrogen, a propellant that is vexing to handle but rewarding in its efficiency.

The Delta IV Heavy was America’s most powerful launch vehicle for nearly a decade and has been a cornerstone for the US military’s space program for more than 20 years. It is also the world’s most expensive commercially produced rocket, a fact driven not just by its outsized capability but also its complexity.

Now, United Launch Alliance’s last Delta IV Heavy rocket is set to lift off Thursday from Cape Canaveral Space Force Station, Florida, with a classified payload for the National Reconnaissance Office, the US government’s spy satellite agency.

“This is such an amazing piece of technology, 23 stories tall, a half-million gallons of propellant and a quarter-million pounds of thrust, and the most metal of all rockets, setting itself on fire before it goes to space,” said Tory Bruno, ULA’s president and CEO. “Retiring it is (key to) the future, moving to Vulcan, a less expensive higher-performance rocket. But it’s still sad.”

45th and final Delta IV

Weather permitting, the Delta IV Heavy will light up its three hydrogen-fueled RS-68A engines at 1: 40 pm EDT (17: 40 UTC) Thursday, the opening of a four-hour launch window. The three RS-68s will fire up in a staggered sequence, a permutation designed to minimize the hydrogen fireball that ignites around the base of the rocket during engine startup.

The Delta IV Heavy will certainly have a legacy of launching national security missions, along with NASA’s Orion spacecraft on an orbital test flight in 2014 and NASA’s Parker Solar Probe in 2018 on a mission to fly through the Sun’s outer atmosphere.

But the fireball will leave an indelible mark in the memories of anyone who saw a Delta IV Heavy launch. It all comes down to the choice of super-cold liquid hydrogen as the fuel. The three RS-68 engines burn hydrogen along with liquid oxygen as the oxidizer.

“We like those propellants because they’re very, very high performance,” Bruno said. “In order to prepare the RS-68 engines to get that very cold cryogenic propellant flowing through them, before they’re ignited, we start flowing that propellant.

“Hydrogen is lighter than air, so after it flows through the engine and into the flame trench, it then rises. When the engines are finally full and ready to go and we start spinning up the pumps, then we actually drop the main load (of propellant), we ignite it, and that flame carries on up that … plume of hydrogen, which is clinging to the side of the booster and rising up.”

The Delta IV rocket cores are covered in orange foam insulation. One of the reasons for this is to protect the rocket from the fireball, leading to a “very dramatic effect of a self-immolating booster” that has the appearance of a “toasted marshmallow” as it heads to space.

A few seconds after the engines start, 12 hold-down bolts will blow to release the triple-core rocket from its restraints. More than 2 million pounds of thrust will power the Delta IV Heavy off the launch pad toward the east from Cape Canaveral. The RS-68 on the center core will throttle down to conserve liquid hydrogen and liquid hydrogen propellant, while the rocket’s two side boosters will burn through their propellants in less than four minutes.

Once the Delta IV lets go of its side boosters and falls into the Atlantic Ocean, the center core throttles up and burns for another minute and a half. A few moments later, the first stage booster jettisons, and the upper stage’s RL10 engine ignites for the first of three burns needed to propel the rocket’s classified cargo into an orbit thousands of miles above Earth.

There’s just a 30 percent chance of favorable weather for liftoff Thursday. High winds and cumulus clouds are the primary concerns. The weather forecast improves for a backup launch opportunity Friday afternoon.

Welcome to Edition 6.36 of the Rocket Report! SpaceX wants to launch the next Starship test flight as soon as early May, the company’s president and chief operating officer said this week. The third Starship test flight last week went well enough that the Federal Aviation Administration—yes, the FAA, the target of many SpaceX fans’ frustrations—anticipates a simpler investigation and launch licensing process than SpaceX went through before its previous Starship flights. However, it looks like we’ll have to wait a little longer for Starship to start launching real satellites.

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.

Starship could threaten small launch providers. Officials from several companies operating or developing small satellite launch vehicles are worried that SpaceX’s giant Starship rocket could have a big impact on their marketability, Space News reports. Starship’s ability to haul more than 100 metric tons of payload mass into low-Earth orbit will be attractive not just for customers with heavy satellites but also for those with smaller spacecraft. Aggregating numerous smallsats on Starship will mean lower prices than dedicated small satellite launch companies can offer and could encourage customers to build larger satellites with cheaper parts, further eroding business opportunities for small launch providers.

Well, yeah … SpaceX’s dedicated rideshare missions are already reshaping the small satellite launch market. The price per kilogram of payload on a Falcon 9 rocket launching a Transporter mission is less than the price per unit on a smaller rocket, like Rocket Lab’s Electron, Firefly’s Alpha, or Europe’s Vega. Companies operating only in the smallsat launch market tout the benefits of their services, often pointing to their ability to deliver payloads into bespoke orbits, rather than dropping off bunches of satellites into more standardized orbits. But the introduction of Orbital Transfer Vehicles for last-mile delivery services has made SpaceX’s Transporter missions, and potentially Starship rideshares, more attractive. “With Starship, OTVs can become the best option for smallsats,” said Marino Fragnito, senior vice president and head of the Vega business unit at Arianespace. If Starship is able to achieve the very low per-kilogram launch prices proposed for it, “then it will be difficult for small launch vehicles,” Fragnito said.

Rocket Lab launches again from Virginia. Rocket Lab’s fourth launch from Wallops Island, Virginia, and the company’s first there in nine months, took off early Thursday with a classified payload for the National Reconnaissance Office, the US government’s spy satellite agency, Space News reports. A two-stage Electron rocket placed the NRO’s payload into low-Earth orbit, and officials declared it a successful mission. The NRO did not disclose any details about the payload, but in a post-launch statement, the agency suggested the mission was conducting technology demonstrations of some kind. “The knowledge gained from this research will advance innovation and enable the development of critical new technology,” said Chris Scolose, director of the NRO.

A steady customer for Rocket Lab … The National Reconnaissance Office has become a regular customer of Rocket Lab. The NRO has historically launched larger spacecraft, such as massive bus-sized spy satellites, but like the Space Force, is beginning to launch larger numbers of small satellites. This mission, designated NROL-123 by the NRO, was the fifth and last mission under a Rapid Acquisition of a Small Rocket (RASR) contract between NRO and Rocket Lab, dating back to 2020. It was also Rocket Lab’s second launch in nine days, following an Electron flight last week from its primary base in New Zealand. Overall, it was the 46th launch of a light-class Electron rocket since it debuted in 2017. Rocket Lab is building a launch pad for its next-generation Neutron rocket at Wallops.

Night flight for Astrobotic’s Xodiac. The Xodiac rocket, a small terrestrial vertical takeoff and vertical landing technology testbed, made its first night flight, Astrobotic says in a statement. The liquid-fueled Xodiac is designed for vertical hops and can host prototype sensors and other payloads, particularly instruments in development to assist in precision landings on other worlds. This first tethered night flight of Xodiac in Mojave, California, was in preparation for upcoming flight testing with the NASA TechLeap Prize’s Nighttime Precision Landing Challenge. These flights will begin in April, allowing NASA to test the ability of sensors to map a landing field designed to simulate the Moon’s surface in near-total darkness.

Building on the legacy of Masten … Xodiac has completed more than 160 successful flights, dating back to the vehicle’s original owner, Masten Space Systems. Masten filed for bankruptcy in 2022, and the company was acquired by Astrobotic a couple of months later. Astrobotic’s primary business area is in developing and flying robotic Moon landers, so it has a keen interest in mastering automated landing and navigation technologies like those it is testing with NASA on Xodiac. David Masten, founder of Masten Space Systems, is now chief engineer for Astrobotic’s propulsion and test department. “The teams will demonstrate their systems over the LSPG (Lunar Surface Proving Ground) at night to simulate landing on the Moon during the lunar night or in shadowed craters.” (submitted by Ken the Bin)

A winding road —

Russia’s heavy-lift Angara A5 rocket is about to launch on its fourth test flight.

By some measures, Russia’s next-generation flagship rocket program—the Angara—is now three decades old. The Russian government approved the development of the Angara rocket in 1992, soon after the fall of the Soviet Union ushered in a prolonged economic recession.

It has been nearly 10 years since Russia launched the first Angara test flights. The heaviest version of the Angara rocket family—the Angara A5—is about to make its fourth flight, and like the three launches before, this mission won’t carry a real satellite.

This next launch will be a milestone for the beleaguered Angara rocket program because it will be the first Angara flight from the Vostochny Cosmodrome, Russia’s newest launch site in the country’s far east. The previous Angara launches were based out of the military-run Plesetsk Cosmodrome in northern Russia.

All dressed up and nowhere to go

On Wednesday, Russia’s space agency, Roscosmos, said technicians at Vostochny have fueled the Angara A5’s Orion upper stage and will soon install it on the rest of the rocket. The Angara A5 will roll to its launch pad a few days before liftoff, currently scheduled for next month.

The Angara A5 rocket is supposed to replace Russia’s Proton launch vehicle, which uses toxic propellant and only launches from the Baikonur Cosmodrome in Kazakhstan. Angara’s launch pads are on Russian territory. Until a few years ago, the Proton was a competitor in the global commercial launch market, but the rocket lost its position due to reliability problems, competitive pressure from SpaceX, and the fallout of Russia’s invasion of Ukraine.

Russian officials once touted Angara as a successor to Proton on the commercial market. Now, Angara will solely serve the Russian government, but it’s doubtful the government has enough demand to fill the Angara A5’s heavy launch capacity on a regular basis. According to RussianSpaceWeb.com, a website run by veteran Russian space reporter Anatoly Zak, the Russian government didn’t have any functional satellites ready to fly on the upcoming Angara A5 launch from Vostochny.

Eventually, the Angara A5 could take over the launch responsibility of the handful of large satellites that require the capacity of the Proton rocket. But this is a small number of flights. The Proton has launched three times in the last two years, and there are roughly a dozen Proton launch vehicles remaining in Russia’s inventory.

Russia plans a next-generation crew spacecraft, Orel, that officials claim will begin launching on the Angara A5 rocket in 2028. There’s no evidence Orel could be ready for test flights within four years. So, while the Angara rocket is finally flying, albeit at an anemic rate, there aren’t many payloads for Russia to put on it.

North Korean leader Kim Jong Un and Russian President Vladimir Putin visited the Angara rocket's launch pad at the Vostochny Cosmodrome last year.

Russia’s economic woes might explain some of the delays that have befallen the Angara program since 1992, but Russia’s space program has long suffered from chronic underfunding, mismanagement, and corruption. Angara is the only rocket Russia has developed from scratch since the 1980s, and the Russian government selected Khrunichev, one of the country’s oldest space companies, to oversee the Angara program.

Finally, in 2014, Russia launched the first two Angara test flights, one with a single-booster lightweight version of the rocket, called the Angara 1.2, and another with the heavy-lift Angara A5, made up of five Angara rocket cores combined into one rocket.

The Angara A5 can place up to 24.5 metric tons (about 54,000 pounds) into low-Earth orbit, according to Khrunichev. The expendable rocket has enough power to launch modules for a space station or deploy the Russian military’s largest spy satellites, but in 2020, each Angara A5 reportedly cost more than $100 million, significantly more than the Proton.

The smaller Angara 1.2 has flown twice since 2014, but both missions delivered functional satellites into orbit for the Russian military. The much larger Angara A5 has launched three times, all with dummy payloads. The most recent Angara A5 launch in 2021 failed due to a problem with the rocket’s Persei upper stage. The Orion upper stage set to fly on the next Angara A5 mission is a modified version of the Persei, which is itself modeled on the Block-DM upper stage, a design with its roots in the 1960s.

Essentially, the Angara A5 flight will allow engineers to test out changes to the upper stage and allow Russia to activate a second launch pad at Vostochny, which itself has been mired in corruption and delays. Medium-lift Soyuz rockets have been flying from Vostochny since 2016.

SpaceX’s oldest Crew Dragon spacecraft launched Sunday night on its fifth mission to the International Space Station, and engineers are crunching data to see if the fleet of Dragons can safely fly as many as 15 times.

It has been five years since SpaceX launched the first Crew Dragon spacecraft on an unpiloted test flight to the space station and nearly four years since SpaceX’s first astronaut mission took off in May 2020. Since then, SpaceX has put its clan of Dragons to use ferrying astronauts and cargo to and from low-Earth orbit.

Now, it’s already time to talk about extending the life of the Dragon spaceships. SpaceX and NASA, which shared the cost of developing the Crew Dragon, initially certified each capsule for five flights. Crew Dragon Endeavour, the first in the Dragon fleet to carry astronauts, is now flying for the fifth time.

This ship has spent 466 days in orbit, longer than any spacecraft designed to transport people to and from Earth. It will add roughly 180 days to its flight log with this mission.

Crew Dragon Endeavour lifted off from Florida aboard a Falcon 9 rocket at 10: 53 pm EST Sunday (03: 53 UTC Monday), following a three-day delay due to poor weather conditions across the Atlantic Ocean, where the capsule would ditch into the sea in the event of a rocket failure during the climb into orbit.

Commander Matthew Dominick, pilot Michael Barratt, mission specialist Jeanette Epps, and Russian cosmonaut Alexander Grebenkin put on their SpaceX pressure suits and strapped into their seats inside Crew Dragon Endeavour Sunday evening at NASA’s Kennedy Space Center. SpaceX loaded liquid propellants into the rocket, while ground teams spent the final hour of the countdown evaluating a small crack discovered on Dragon’s side hatch seal. Managers ultimately cleared the spacecraft for launch after considering whether the crack could pose a safety threat during reentry at the end of the mission.

“We are confident that we understand the issue and can still fly the whole mission safely,” a member of SpaceX’s mission control team told the crew inside Dragon.

This mission, known as Crew-8, launched on a brand-new Falcon 9 booster, which returned to landing a few minutes after liftoff at Cape Canaveral Space Force Station. The Falcon 9’s upper stage released the Dragon spacecraft into orbit about 12 minutes after liftoff. The four-person crew will dock at the space station around 3 am EST (0800 UTC) Tuesday.

Crew-8 will replace the four-person Crew-7 team that has been at the space station since last August. Crew-7 will return to Earth in about one week on SpaceX’s Crew Dragon Endurance spacecraft, which is flying in space for the third time.

The Crew-8 mission came home for a reentry and splashdown off the coast of Florida in late August of this year, wrapping up Crew Dragon Endeavour’s fifth trip to space. This is the current life limit for a Crew Dragon spacecraft, but don’t count out Endeavour just yet.

Fleet management

“Right now, we’re certified for five flights on Dragon, and we’re looking at extending that life out,” said Steve Stich, NASA’s commercial crew program manager. “I think the goal would be for SpaceX to say 15 flights of Dragon. We may not get there in every single system.”

One by one, engineers at SpaceX and NASA are looking at Dragon’s structural skeleton, composite shells, rocket engines, valves, and other components to see how much life is left in them. Some parts of the spacecraft slowly fatigue from the stresses of each launch, reentry, and splashdown, along with the extreme temperature swings the capsule sees thousands of times in orbit. Each Draco thruster on the spacecraft is certified for a certain number of firings.

Some components are already approved for 15 flights, Stich said in a recent press conference. “Some, we’re still in the middle of working on,” he said. “Some of those components have to go through some re-qualification to make sure that they can make it out to 15 flights.”

Re-qualifying a component on a spacecraft typically involves putting hardware through extensive testing on the ground. Because SpaceX reuses hardware, engineers can remove a part from a flown Dragon spacecraft and put it through qualification testing. NASA will get the final say in certifying the Dragon spacecraft for additional flights because the agency is SpaceX’s primary customer for crew missions.

The Dragon fleet is flying more often than SpaceX or NASA originally anticipated. The main reason for this is that Boeing, NASA’s other commercial crew contractor, is running about four years behind SpaceX in getting to its first astronaut launch on the Starliner spacecraft.

When NASA selected SpaceX and Boeing for multibillion-dollar commercial crew contracts in 2014, the agency envisioned alternating between Crew Dragon and Starliner flights every six months to rotate four-person crews at the International Space Station. With Boeing’s delays, SpaceX has picked up the slack.
