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 Japanese spacecraft faceplanted on the Moon and lived to tell the tale

Japan's SLIM spacecraft is seen nose down on the surface of the Moon.

Japan’s SLIM spacecraft is seen nose down on the surface of the Moon.

Japan’s first lunar lander made an unsteady touchdown on the Moon last week, moments after one of its two main engines inexplicably lost power and apparently fell off the spacecraft, officials said Thursday.

About the size of a small car, the Small Lander for Investigating Moon (SLIM) landed on Friday, making Japan the fifth country to achieve a soft landing on the lunar surface. Shortly after landing, ground teams in Japan realized the spacecraft was not recharging its battery with its solar panels. The evidence at the time suggested that SLIM likely ended up in an unexpected orientation on the Moon, with its solar cells facing away from the Sun.

With the benefit of six days of data crunching and analysis, officials from the Japan Aerospace Exploration Agency (JAXA) briefed reporters Thursday on what they have learned about SLIM’s landing. Indeed, the spacecraft toppled over after touching down, with its nose planted into the lunar regolith and its rear propulsion section pointed toward space.

It turns out that SLIM overcame a lot to get to that point. In the final minute of Friday’s descent, one of SLIM’s two engines failed, leaving the craft’s sole remaining engine to bring the spacecraft in for an off-balance landing. Still, JAXA officials said the spacecraft achieved nearly all of its primary objectives. The roughly $120 million robotic mission made the most pinpoint landing on the Moon in history, just as it set out to do.

“From the spacecraft, we were able to acquire all the technical data related to navigation guidance leading to landing, which will be necessary for future pinpoint landing technology, as well as navigation camera image data during descent and on the lunar surface,” JAXA said in a statement.

One of two tiny robots released by SLIM just before landing relayed a remarkable image of the lander standing upside down a short distance away. This might be the first close-up view of a crash landing, however gentle, on another world.

One plucky bird

Based on the update JAXA released Thursday, it’s extraordinary that SLIM made it to the surface in one piece.

After launching in September and arriving at the Moon in December, SLIM lined up for a final descent to the lunar surface on Friday. Around 20 minutes before landing, the spacecraft ignited its two hydrazine-fueled rocket engines for a braking maneuver to drop out of lunar orbit.

JAXA officials said everything went according to plan in the initial phases of the descent. The spacecraft pitched over from a horizontal orientation to begin a final vertical descent to the surface. SLIM’s guidance computer was preloaded with a map of the landing zone, and an onboard navigation camera took pictures of the Moon’s surface throughout the landing sequence. The spacecraft’s computer used these images to compare to the map, allowing SLIM to autonomously correct its course along the way.

The SLIM spacecraft was built by Mitsubishi Electric under contract with JAXA.

But at an altitude of around 160 feet (50 meters), something went wrong with the spacecraft’s propulsion system. Less than a minute before touchdown, one of the engines suddenly lost thrust, and moments later, a down-facing navigation camera caught a glimpse of what appeared to be one of the engine nozzles falling away from the spacecraft. JAXA said engineers believe the engine failure was likely caused by “some external factor other than the main engine itself.” Officials are still investigating to determine the root cause.

The spacecraft continued descending on the power of its remaining engine, but it became more difficult to control the lander. The thrust from the single engine imparted a sideways motion to the spacecraft. Normally, SLIM would have used thrusters to tilt itself from the vertical orientation necessary for the final descent and into a position to plop itself on the lunar surface along the spacecraft’s long axis. SLIM had five crushable landing legs to absorb the force of the gentle impact.

While this two-stage landing sequence was the plan, JAXA said Thursday that the spacecraft “touched the ground in an almost straight standing position with lateral velocity.” The vertical speed at touchdown was about 3.1 mph (1.4 meters per second), slightly slower than the expected descent rate.

“Because the ground contact conditions such as lateral speed and attitude exceeded the specification range, a large attitude change occurred after touchdown, and the aircraft settled in a different attitude than expected,” JAXA said.

In other words, the squirrelly landing caused the spacecraft to tip over. SLIM settled in a bottoms-up position on a shallow slope rather than on its side. Its solar panel wasn’t facing up but was instead pointed toward the west, away from the Sun’s position in the eastern morning sky at the landing site.

NASA urged Astrobotic not to send its hamstrung spacecraft toward the Moon

Astrobotic knew its first space mission would be rife with risks. After all, the company’s Peregrine spacecraft would attempt something never done before—landing a commercial spacecraft on the surface of the Moon.

The most hazardous part of the mission, actually landing on the Moon, would happen more than a month after Peregrine’s launch. But the robotic spacecraft never made it that far. During Peregrine’s startup sequence after separation from its United Launch Alliance Vulcan rocket, one of the spacecraft’s propellant tanks ruptured, spewing precious nitrogen tetroxide into space. The incident left Peregrine unable to land on the Moon, and it threatened to kill the spacecraft within hours of liftoff.

“What a wild adventure we were just on, not the outcome we were hoping for,” said John Thornton, CEO of Astrobotic.

Astrobotic’s control team, working out of the company’s headquarters in Pittsburgh, swung into action to save the spacecraft. The propellant leak abated, and engineers wrestled control of the spacecraft to point its solar arrays toward the Sun, allowing its battery to recharge. Over time, Peregrine’s situation stabilized, although it didn’t have enough propellant remaining to attempt a descent to the lunar surface.

Peregrine continued on a trajectory out to 250,000 miles (400,000 kilometers) from Earth, about the same distance as the Moon’s orbit. Astrobotic’s original flight plan would have taken Peregrine on one long elliptical loop around Earth, then the spacecraft would have reached the Moon during its second orbit.

On its way back toward Earth, Peregrine was on a flight path that would bring it back into the atmosphere, where it would burn up on reentry. That meant Astrobotic had a decision to make. With Peregrine stabilized, should they attempt an engine burn to divert the spacecraft away from Earth onto a trajectory that could bring it to the vicinity of the Moon? Or should Astrobotic keep Peregrine in line to reenter Earth’s atmosphere and avoid the risk of sending a crippled spacecraft out to the Moon?

Making lemonade out of lemons

This was the first time Astrobotic had flown a space mission, and its control team had much to learn. The malfunction that caused the propellant leak appears to have been with a valve that did not properly reseat during the propulsion system’s initialization sequence. This valve activated to pressurize the fuel and oxidizer tanks with helium.

When the valve didn’t reseat, it sent a “rush of helium” into the oxidizer system, Thornton said. “I describe it as a rush because it was very, very fast. “Within a little over a minute, the pressure had risen to the point in the oxidizer side that it was well beyond the proof limit of the propulsion tank. We believe at that point the tank ruptured and led to, unfortunately, a catastrophic loss of propellant … for the primary mission.”

Thornton described the glum mood of Astrobotic’s team after the propellant leak.

“We were coming from the highest high of a perfect launch and came down to the lowest low, when we found out that the spacecraft no longer had the helium and no longer had the propulsion needed to attempt the Moon landing,” he said. “What happened next, I think, was pretty remarkable and inspiring.”

In a press briefing Friday, Thornton outlined the obstacles Astrobotic’s controllers overcame to keep Peregrine alive. Without a healthy propulsion system, the spacecraft’s solar panels were not pointed at the Sun. With a few minutes to spare, one of Astrobotic’s engineers, John Shaffer, devised a solution to reorient the spacecraft to start recharging its battery.

As Peregrine’s oxidizer tank lost pressure, the leak rate slowed. At first, it looked like the spacecraft might have only hours of propellant remaining. Then, Astrobotic reported on January 15 that the leak had “practically stopped.” Mission controllers powered up the science payloads aboard the Peregrine lander, proving the instruments worked and demonstrating the spacecraft could have returned data from the lunar surface if it landed.

The small propulsive impulse from the leaking oxidizer drove Peregrine slightly off course, putting it on a course to bring it back into Earth’s atmosphere. This set up Astrobotic for a “very difficult decision,” Thornton said.

Nudging Peregrine off its collision course with Earth would have required the spacecraft to fire its main engines, and even if that worked, the lander would have needed to perform more maneuvers to get close to the Moon. A landing was still out of the question, but Thornton said there was a small chance Astrobotic could have guided Peregrine toward a flyby or impact with the Moon.

“The thing we were weighing was, ‘Should we send this back to Earth, or should we take the risk to operate it in cislunar space and see if we can send this out farther?'” Thornton said.

Japan becomes the fifth nation to land a spacecraft on the Moon

The Japanese space agency’s first lunar lander arrived on the the Moon’s surface Friday, but a power system problem threatens to cut short its mission.

Japan’s robotic Smart Lander for Investigating Moon (SLIM) mission began a 20-minute final descent using two hydrazine-fueled engines to drop out of orbit. After holding to hover at 500 meters and then 50 meters altitude, SLIM pulsed its engines to fine-tune its vertical descent before touching down at 10: 20 am EST (15: 20 UTC).

The Japan Aerospace Exploration Agency (JAXA), which manages the SLIM mission, streamed the landing live on YouTube. About two hours after the touchdown, JAXA officials held a press conference to confirm the spacecraft made a successful landing, apparently quite close to its target. SLIM aimed to settle onto the lunar surface adjacent to a nearly 900-foot (270-meter) crater named Shioli, located in a region called the Sea of Nectar on the near side of the Moon.

But ground controllers at JAXA’s Sagamihara Campus in the western suburbs of Tokyo soon discovered the lander was in trouble. Its solar array was not generating electricity after landing, and without power, officials expected SLIM to drain its battery within a few hours.

In what could be the mission’s final hours, engineers prioritized downloading data from SLIM, including imagery taken during its descent, and potentially new pictures captured from the lunar surface. Official reported good communications links between SLIM and ground stations on Earth.

“Minimum success”

Even if SLIM falls silent, the mission has achieved its minimum success criteria, JAXA said. The SLIM mission is a technology demonstrator developed to verify the performance of a new vision-based navigation system needed for precision Moon landings.

“First and foremost, landing was made and communication was established,” said Hiroshi Yamakawa, JAXA’s president. “So a minimum success was made in my view.”

One of the core goals of the SLIM mission was to land within 100 meters (about 330 feet) of its bullseye. This accomplishment would be a remarkable improvement in lunar landing precision, which typically is measured in miles or kilometers. It would also be an enabling capability for future Moon missions because it lays the foundation for future spacecraft to land closer to lunar resources, such as water ice.

Hitoshi Kuninaka, director general of JAXA’s Institute of Space and Astronautical Science, said it will take about a month for engineers to fully analyze data from SLIM and determine the precision of the landing.

“But as you saw on the real-time data livestream, SLIM did trace the expected course, so my personal impression is that we probably have been able to more or less achieve a high precision landing within 100-meter accuracy,” Kuninaka said. “So the solar cell state is unlikely to impact the full success criteria.”

Kuninaka said ground teams have seen no evidence of any damage to the solar array on SLIM. It’s possible the lander is sitting in an orientation with its solar cells facing away from the Sun. All other components of SLIM, including its propulsion, thermal, and communication systems, all appear to be functioning well.

SLIM launched September 6 on top of a Japanese H-IIA rocket, riding to orbit alongside an X-ray astronomy telescope. The spacecraft took a long route to get to the Moon, trading time for fuel to preserve propellant for Friday’s landing attempt. SLIM entered orbit around the Moon on December 25, then completed several maneuvers to settle into a low-altitude orbit in preparation for the descent to the surface.

A milestone moment for Japan

The landing of SLIM made Japan the fifth country to soft-land a spacecraft on the Moon, following the Soviet Union, the United States, China, and India. But landing on the Moon is a hazardous thing to do. Three commercial landers similar in scale to SLIM failed to safely reach the lunar surface over the last five years.

One of those was developed by a Japanese company called ispace. Most recently, the US company Astrobotic attempted to send its Peregrine lander to the Moon, but a propellant leak cut short the mission. After looping more than 200,000 miles into space, Peregrine reentered Earth’s atmosphere Wednesday, where it was expected to burn up 10 days after its launch.

A Russian lander crashed into the Moon in August, and India’s first lunar lander failed in 2019. India tried again last year and made history when Chandrayaan 3 safely landed.

Japan’s SLIM mission was primarily designed to test out new guidance algorithms and sensors, rather than pursuing scientific objectives. The technologies riding to the Moon on SLIM could be used on future spacecraft bound for the Moon. SLIM cost the Japanese government approximately 18 billion yen ($121 million) to design, develop, and build, according to JAXA.

The spacecraft is modest in size, measuring nearly 8 feet (2.4 meters) tall and nearly 9 feet (2.7 meters) across. Without propellant in its tanks, SLIM has a mass of roughly 660 pounds (200 kilograms).

“The start of the deceleration to the landing on the Moon’s surface is expected to be a breathless, numbing 20 minutes of terror!” said Kushiki Kenji, sub-project manager for the SLIM mission, before the landing.

United Launch Alliance

CAPE CANAVERAL, Florida—Right out of the gate, United Launch Alliance’s new Vulcan rocket chased perfection.

The Vulcan launcher hit its marks after lifting off from Florida’s Space Coast for the first time early Monday, successfully deploying a commercial robotic lander on a journey to the Moon and keeping ULA’s unblemished success record intact.

“Yeehaw! I am so thrilled, I can’t tell you how much!” exclaimed Tory Bruno, ULA’s president and CEO, shortly after Vulcan’s departure from Cape Canaveral. “I am so proud of this team. Oh my gosh, this has been years of hard work. So far, this has been an absolutely beautiful mission.”

This was a pivotal moment for ULA, a 50-50 joint venture between Boeing and Lockheed Martin. The Vulcan rocket will replace ULA’s mainstay rockets, the Atlas V and Delta IV, with lineages dating back to the dawn of the Space Age. ULA has contracts for more than 70 Vulcan missions in its backlog, primarily for the US military and Amazon’s Project Kuiper broadband network.

The Vulcan rocket lived up to the moment Monday. It took nearly a decade for ULA to develop it, some four years longer than anticipated, but the first flight took off at the opening of the launch window on the first launch attempt.

Standing 202 feet (61.6 meters) tall, the Vulcan rocket ignited its two BE-4 main engines in the final seconds of a smooth countdown. A few moments later, two strap-on solid rocket boosters flashed to life to propel the Vulcan rocket off its launch pad at 2: 18 am EST (07: 18 UTC).

On the money

The BE-4 engines and solid-fueled boosters combined to generate more than 2 million pounds of thrust, vaulting Vulcan off the launch pad and through a thin cloud layer. A little over a minute after launch, Vulcan accelerated faster than the speed of sound, then jettisoned its strap-on boosters to fall into the Atlantic Ocean.

Then it was all BE-4. Each of these engines can produce more than a half-million pounds of thrust, consuming a mixture of liquified natural gas—essentially methane—and liquid oxygen. They are built by Blue Origin, the space company founded by billionaire Jeff Bezos. This was the first time BE-4s have flown on a rocket.

Rob Gagnon, ULA’s telemetry commentator, calmly called out mission milestones. “BE-4s continue to operate nominally… Vehicle is continuing to fly down the center of the range track, everything looking good… Nice and smooth operation of the booster.”

The BE-4s fired for five minutes, then shut down to allow Vulcan’s first stage booster to fall away from the rocket’s hydrogen-fueled Centaur upper stage. Two RL10 engines ignited to continue the push into orbit, then switched off as the upper stage coasted over the Atlantic and Africa. A restart of the Centaur upper stage 43 minutes into the flight gave the rocket enough velocity to send Astrobotic’s Peregrine lunar lander toward the Moon.

The nearly 1.5-ton spacecraft separated from Vulcan’s Centaur upper stage around 50 minutes after liftoff. “We have spacecraft separation, right on time,” Gagnon announced.

With Astrobotic’s lander deployed, a third engine firing on the Centaur upper stage moved the rocket off its Moon-bound trajectory and onto a course into heliocentric orbit. “We have now achieved Earth escape,” Gagnon said.

The spent rocket stage will become a human-made artificial satellite of the Sun. A plate on the side of the Centaur upper stage contains small capsules holding the cremated remains of more than 200 people, a “memorial spaceflight” arranged by a Houston-based private company named Celestis.

Navajo objection to flying human ashes to the Moon won’t delay launch

Science instruments aren’t the only things hitching a ride to the Moon on a commercial lunar lander ready for launch Monday. Two companies specializing in “space burials” are sending cremated human remains to the Moon, and this doesn’t sit well with the Navajo Nation.

The Navajo people, one of the nation’s largest Indigenous groups, hold the Moon sacred, and putting human remains on the lunar surface amounts to desecration, according to Navajo Nation President Buu Nygren.

“The sacredness of the Moon is deeply embedded in the spirituality and heritage of many Indigenous cultures, including our own,” Nygren said in a statement. “The placement of human remains on the Moon is a profound desecration of this celestial body revered by our people.”

Last month, Nygren wrote a letter to NASA and the Department of Transportation, which licenses commercial space launches, requesting a postponement of the flight to the Moon. The human remains in question are mounted to the robotic Peregrine lander, built and owned by a Pittsburgh-based company named Astrobotic, poised for liftoff from Cape Canaveral Space Force Station in Florida on top of United Launch Alliance’s Vulcan rocket.

This is the second time a US spacecraft has gone to the Moon with human remains aboard. In 1998, NASA’s Lunar Prospector mission launched with a small capsule containing the ashes of Eugene Shoemaker, a pioneer in planetary geology. NASA intentionally crashed spacecraft into the Moon in 1999, leaving Shoemaker’s ashes permanently on the surface.

At that time, officials from the Navajo Nation objected to the scattering of Shoemaker’s ashes on the Moon. NASA promised to consult with tribal officials before another spacecraft flew to the Moon with human remains. A big part of Nygren’s recent complaint was the lack of dialogue on the matter before this mission.

“This act disregards past agreements and promises of respect and consultation between NASA and the Navajo Nation, notably following the Lunar Prospector mission in 1998,” Nygren said in a statement. He added that the request for consultation is “rooted in a desire to ensure that our cultural practices, especially those related to the Moon and the treatment of the deceased, are respected.”

An oversight

Officials from the White House and NASA met with Nygren on Friday to discuss his concerns. Speaking with reporters after the meeting, Nygren said he believes it was an oversight that federal officials didn’t meet with the Navajo Nation at an earlier stage.

“I think being able to consult into the future is one of the things that they’re going to try to work on,” he told reporters Friday. While Nygren said that was good to hear, “we were given no reassurance that the human remains were not going to be transported to the Moon on Monday.”

Removing the human remains would delay the launch at least several weeks. It would require removing Astrobotic’s lunar lander from the top of the Vulcan rocket, taking it back to a clean room facility, and opening the payload fairing to provide access to the spacecraft.

“They’re not going to remove the human remains and keep them here on Earth where they were created, but instead, we were just told that a mistake has happened, we’re sorry, into the future we’re going to try to consult with you,” Nygren said.

“We take concerns expressed from the Navajo Nation very, very seriously,” said Joel Kearns, deputy associate administrator for exploration in NASA’s science directorate. “And we think we’re going to be continuing this conversation.”

Astrobotic’s mission is different from Lunar Prospector in one important sense. The Peregrine lander is privately owned, while Lunar Prospector was a government spacecraft. NASA has a $108 million contract with Astrobotic to deliver the agency’s science payloads to the Moon as a commercial service. Astrobotic’s mission is the first time a US company will attempt to land a commercial spacecraft on the Moon.

While Nygren argues that NASA’s role as Astrobotic’s anchor customer should give the agency some influence over decision-making, the government’s only legal authority in overseeing the mission is through the Federal Aviation Administration.

The FAA is responsible for ensuring commercial launches, like the Vulcan rocket flight Monday, don’t put public safety at risk. The launch licensing process also includes an FAA review to ensure a launch would not jeopardize US national security, foreign policy interests, or international obligations.

“For our own missions … NASA works to be very mindful of potential concerns for any work that we’ll do on the Moon,” Kearns said. “In this particular case … NASA really doesn’t have involvement or oversight.”
