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

Some time next year, NASA believes SpaceX will be ready to link two Starships in orbit for an ambitious refueling demonstration, a technical feat that will put the Moon within reach.

SpaceX is under contract with NASA to supply two human-rated Starships for the first two astronaut landings on the Moon through the agency’s Artemis program, which aims to return people to the lunar surface for the first time since 1972. The first of these landings, on NASA’s Artemis III mission, is currently targeted for 2026, although this is widely viewed as an ambitious schedule.

Last year, NASA awarded a contract to Blue Origin to develop its own human-rated Blue Moon lunar lander, giving Artemis managers two options for follow-on missions.

Designers of both landers were future-minded. They designed Starship and Blue Moon for refueling in space. This means they can eventually be reused for multiple missions, and ultimately, could take advantage of propellants produced from resources on the Moon or Mars.

Amit Kshatriya, who leads the “Moon to Mars” program within NASA’s exploration division, outlined SpaceX’s plan to do this in a meeting with a committee of the NASA Advisory Council on Friday. He said the Starship test program is gaining momentum, with the next test flight from SpaceX’s Starbase launch site in South Texas expected by the end of May.

“Production is not the issue,” Kshatriya said. “They’re rolling cores out. The engines are flowing into the factory. That is not the issue. The issue is it is a significant development challenge to do what they’re trying to do … We have to get on top of this propellant transfer problem. It is the right problem to try and solve. We’re trying to build a blueprint for deep space exploration.”

Road map to refueling

Before getting to the Moon, SpaceX and Blue Origin must master the technologies and techniques required for in-space refueling. Right now, SpaceX is scheduled to attempt the first demonstration of a large-scale propellant transfer between two Starships in orbit next year.

There will be at least several more Starship test flights before then. During the most recent Starship test flight in March, SpaceX conducted a cryogenic propellant transfer test between two tanks inside the vehicle. This tank-to-tank transfer of liquid oxygen was part of a demonstration supported with NASA funding. Agency officials said this demonstration would allow engineers to learn more about how the fluid behaves in a low-gravity environment.

Kshatriya said that while engineers are still analyzing the results of the cryogenic transfer demonstration, the test on the March Starship flight “was successful by all accounts.”

“That milestone is behind them,” he said Friday. Now, SpaceX will move out with more Starship test flights. The next launch will try to check off a few more capabilities SpaceX didn’t demonstrate on the March test flight.

These will include a precise landing of Starship’s Super Heavy booster in the Gulf of Mexico, which is necessary before SpaceX tries to land the booster back at its launch pad in Texas. Another objective will likely be the restart of a single Raptor engine on Starship in flight, which SpaceX didn’t accomplish on the March flight due to unexpected roll rates on the vehicle as it coasted through space. Achieving an in-orbit engine restart—necessary to guide Starship toward a controlled reentry—is a prerequisite for future launches into a stable higher orbit, where the ship could loiter for hours, days, or weeks to deploy satellites and attempt refueling.

In the long run, SpaceX wants to ramp up the Starship launch cadence to many daily flights from multiple launch sites. To achieve that goal, SpaceX plans to recover and rapidly reuse Starships and Super Heavy boosters, building on expertise from the partially reusable Falcon 9 rocket. Elon Musk, SpaceX’s founder and CEO, is keen on reusing ships and boosters as soon as possible. Earlier this month, Musk said he is optimistic SpaceX can recover a Super Heavy booster in Texas later this year and land a Starship back in Texas sometime next year.

Nine kerosene-fueled Rutherford engines power Rocket Lab's Electron launch vehicle off the pad at Wallops Island, Virginia, early Thursday.

Enlarge / Nine kerosene-fueled Rutherford engines power Rocket Lab’s Electron launch vehicle off the pad at Wallops Island, Virginia, early Thursday.

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)

Excitement guaranteed —

This third flight has a reasonable chance of success.

SpaceX

After SpaceX completed a fueling test of its third full Starship stack on Sunday night, successfully loading more than 10 million pounds of methane and liquid oxygen propellant onto the rocket, it was only a matter of time before the world’s largest rocket took flight.

Now, we have a tentative date. In a post on the social media site X, the company posted a link to watch “Starship’s third flight test” at 7: 30 am ET (11: 30 UTC) on March 14. Published on Tuesday morning, the social media post was ‘hidden,’ but somehow discovered late Tuesday night.

Nevertheless, this is a credible date that the company is working toward. Following the fueling test on Sunday night at the company’s Starbase site in South Texas, the hardware appears to be in good shape. Although SpaceX has yet to receive its launch license from the Federal Aviation Administration, the agency recently announced that it has closed its investigation into the second Starship test flight in November. So a mid-March launch date is plausible from a regulatory standpoint.

The first two Starship flights in April and November last year ultimately failed, but each of the experimental launches provided valuable data. On the second mission four months ago, the first-stage Super Heavy booster performed a nominal flight before it separated from the Starship upper stage. The Starship vehicle exploded a few minutes into its flight due to a leak during a liquid oxygen vent.

Based upon learnings from these first two flights, this next mission, with upgraded hardware and flight software, likely has a reasonable chance of success. Among the milestones SpaceX will seek to complete during this test flight are:

  • Nominal first-stage performance, followed by a controlled descent of the Super Heavy booster into the Gulf of Mexico
  • Starship separation from the first stage using “hot staging,” meaning engine ignition while the first stage is still firing its engines
  • Starship reaching an orbital velocity and engine shutdown
  • Early-stage testing of in-space refueling technology inside the propellant tanks of Starship
  • Controlled splashdown of Starship near the Hawaiian islands after flying around two-thirds of the planet.

SpaceX is seeking to demonstrate the basic flight capabilities of Starship so that it can move into a more operational phase with the big rocket. The company wants to begin deploying larger Starlink satellites from the vehicle this year, which will enable direct-to-cell phone Internet connectivity.

Additionally, a higher cadence of missions will allow the company to begin developing the technology and procedures needed for the in-space storage and transfer of propellant for deep-space missions. This is a necessary step for SpaceX to fulfill its obligations to NASA for the Artemis program, which seeks to return humans to the Moon later this decade.

In a recent update, the company said more Starships are ready for flight, so a higher cadence is possible if this month’s flight is a success. Recently, the Federal Aviation Administration disclosed that SpaceX is seeking to launch Starship at least nine times this year.

RUD —

“Several engines began shutting down before one engine failed energetically.”

SpaceX

A little more than three months after the most recent launch of a Starship vehicle, which ended with both the booster and upper stage being lost in flight, the Federal Aviation Administration has closed its investigation of the mishap.

“SpaceX identified, and the FAA accepts, the root causes and 17 corrective actions documented in SpaceX’s mishap report,” the federal agency said in a statement issued Monday. “Prior to the next launch, SpaceX must implement all corrective actions and receive a license modification from the FAA that addresses all safety, environmental and other applicable regulatory requirements.”

SpaceX must still submit additional information to the FAA, which is responsible for the safety of people and property on the ground, before the agency completes its review of an application to launch Starship for a third time. The administrator for Commercial Space Transportation at the Federal Aviation Administration, Kelvin Coleman, said last week that early to mid-March is a reasonable timeline for the regulatory process to conclude.

A launch attempt is likely to follow soon after.

What went wrong

In conjunction with Monday’s announcement, SpaceX released details for the first time of what happened to cause the November 18 launch to go awry.

In this update, SpaceX noted that the Super Heavy first stage of the rocket performed nominally, with all 33 Raptor engines on this massive rocket igniting successfully. The booster then performed a full-duration burn to reach stage separation. At this point, the upper stage executed a successful “hot staging” maneuver in which the Starship stage separated from the booster while some of the booster’s engines were still firing.

For the Super Heavy booster, the next step was to perform a series of burns to make a soft landing in the Gulf of Mexico. As part of the initial burn, 13 of the rocket’s engines were intended to fire.

“During this burn, several engines began shutting down before one engine failed energetically, quickly cascading to a rapid unscheduled disassembly of the booster,” SpaceX said. “The vehicle breakup occurred more than three and a half minutes into the flight at an altitude of ~90 km over the Gulf of Mexico.”

The problem was subsequently linked to a problem with supplying liquid oxygen to the Raptor engines.

“The most likely root cause for the booster RUD was determined to be filter blockage where liquid oxygen is supplied to the engines, leading to a loss of inlet pressure in engine oxidizer turbopumps that eventually resulted in one engine failing in a way that resulted in loss of the vehicle,” the company stated. “SpaceX has since implemented hardware changes inside future booster oxidizer tanks to improve propellant filtration capabilities and refined operations to increase reliability.”

Starship vents

As Super Heavy was experiencing these problems, the six Raptor engines on the Starship upper stage were burning nominally and pushing the vehicle along a flight path intended to take it nearly two-thirds of the way around Earth before splashing down near Hawaii. However, at about seven minutes after liftoff, a large vent of liquid oxygen occurred. There was excess liquid oxygen on the vehicle, SpaceX said, to gather data representative of future payload deployment missions. It needed to be released before Starship splashed down.

“A leak in the aft section of the spacecraft that developed when the liquid oxygen vent was initiated resulted in a combustion event and subsequent fires that led to a loss of communication between the spacecraft’s flight computers,” the company said. “This resulted in a commanded shut down of all six engines prior to completion of the ascent burn, followed by the Autonomous Flight Safety System detecting a mission rule violation and activating the flight termination system, leading to vehicle breakup.”

At the time, the vehicle had reached an altitude of 150 km, well into outer space, and had achieved a velocity of about 24,000 km/h. This is just short of orbital velocity, which is 28,000 km/h.

In its statement, SpaceX said it was implementing changes to the Super Heavy and Starship stages to account for these issues. The company is also seeking to improve the overall performance of Starship, with the addition of a new electronic Thrust Vector Control system for Starship’s upper-stage Raptor engines and more rapid propellant loading operations prior to launch.

SpaceX has four Starships in complete, or nearly complete, build stages. Should the next flight go smoothly, the company could begin to launch the world’s largest rocket on a more frequent basis.

Welcome to Edition 6.32 of the Rocket Report! I’m writing the report again this week as Eric Berger is in Washington, DC, to receive a well-earned honor, the 2024 Excellence in Commercial Space Journalism Award from the Commercial Spaceflight Federation. Cape Canaveral is the world’s busiest spaceport, and this week, three leading US launch companies were active there. SpaceX launched another Falcon 9 rocket, and a few miles away, Blue Origin raised a New Glenn rocket on its launch pad for long-awaited ground testing. Nearby, United Launch Alliance began assembling an Atlas V rocket for the first crew launch of Boeing’s Starliner spacecraft in April. 2024 is shaping up to be a truly exciting year for the spaceflight community.

Astroscale inspector satellite launched by Rocket Lab. Astroscale, a well-capitalized Japanese startup, has launched a small satellite to do something that has never been done in space, Ars reports. This new spacecraft, delivered into orbit on February 18 by Rocket Lab, will approach a defunct upper stage from a Japanese H-IIA rocket that has been circling Earth for more than 15 years. Over the next few months, the satellite will try to move within arm’s reach of the rocket, taking pictures and performing complicated maneuvers to move around the bus-size H-IIA upper stage as it moves around the planet at nearly 5 miles per second (7.6 km/s).

This is a first … Astroscale’s ADRAS-J mission is the first satellite designed to approach and inspect a piece of space junk in orbit. This is a public-private partnership between Astroscale and the Japanese space agency. Of course, space agencies and commercial companies have demonstrated rendezvous operations in orbit for decades. The difference here is the H-IIA rocket is uncontrolled, likely spinning and in a slow tumble, and was never designed to accommodate any visitors. Japan left it in orbit in January 2009 following the launch of a climate monitoring satellite and didn’t look back. ADRAS-J is a technology demonstration that could pave the way for a follow-on mission to actually link up with this H-IIA rocket and remove it from orbit. Astroscale eventually wants to use these technologies for satellite servicing, refueling, and further debris removal missions. (submitted by Ken the Bin and Jay500001)

Software error blamed for Firefly launch malfunction. Firefly Aerospace released an update Tuesday on an investigation into an upper stage malfunction on the company’s Alpha rocket in December. The investigation team, consisting of membership from Firefly, the Federal Aviation Administration, the National Transportation Safety Board, Lockheed Martin, NASA, and the US Space Force, determined a software error in the rocket’s guidance, navigation, and control software algorithm ultimately caused the Alpha rocket to release its payload into a lower-than-planned orbit following a launch from California.

Upper stage woes… The software error prevented the rocket from sending the “necessary pulse commands” to control thrusters on the upper stage before its main engine was supposed to reignite. This second burn by the upper stage was supposed to circularize the rocket’s orbit, but it didn’t happen as planned. Still, the Alpha rocket safely released its commercial satellite payload for Lockheed Martin. Although the lower orbit caused the satellite to reenter the atmosphere earlier this month, Lockheed Martin said it was able to achieve many of the objectives of the technology demonstration mission, which focused on testing an electronically steered antenna. This was the fourth launch of an Alpha rocket, and two of them have suffered from upper stage malfunctions during engine restart attempts. Firefly says it is preparing the next Alpha rocket to fly “in the coming months.” (submitted by Ken the Bin)

A good fundraising round for Gilmour Space. Australian startup Gilmour Space Technologies has raised $55 million Australian dollars ($36 million) in a Series D funding round announced Monday, Space News reports. The funding supports the small launch vehicle startup’s campaign to manufacture, test, and begin launching rockets and satellites from the Bowen Orbital Spaceport in North Queensland. Gilmour Space, founded in 2012, is developing a three-stage rocket called Eris. The first Eris test flight is expected “in the coming months, pending launch approvals from the Australian Space Agency,” according to the Gilmour Space news release.

Launching from down under… Gilmour Space is aiming to launch the first Australian-built rocket into orbit later this year. The Eris rocket is powered by hybrid engines, and Gilmour says it is capable of delivering about 670 pounds (305 kilograms) of payload mass into a Sun-synchronous orbit. The $36 million fundraising round announced this week follows a $46 million fundraising round in 2021. According to the Australian Broadcasting Corporation, Gilmour Space is aiming for the first flight of Eris in April, and this latest fundraising should give the company enough money to mount four test flights.

SpaceX wants to take over a Florida launch pad from rival ULA

First step —

SpaceX now plans at least four Starship launch pads, two in Texas and two in Florida.

One of the largest launch pads at Cape Canaveral Space Force Station will become vacant later this year after the final flight of United Launch Alliance’s Delta IV Heavy rocket. SpaceX is looking to make the sprawling facility a new home for the Starship launch vehicle.

The environmental review for SpaceX’s proposal to take over Space Launch Complex 37 (SLC-37) at Cape Canaveral is getting underway now, with three in-person public meetings and one virtual meeting scheduled for March to collect comments from local residents, according to a new website describing the plan.

Then federal agencies, led by the Department of the Air Force, will develop an environmental impact statement to evaluate how Starship launch and landing operations will affect the land, air, and water around SLC-37, which sits on Space Force property on the Atlantic coastline.

Environmental studies for rocket launch facilities typically take more than a year, so it will be a while before any major construction begins to convert SLC-37 for Starship launches. In this case, federal officials anticipate publishing a draft environmental impact statement by December, then a final report by October 2025.

More immediately, ULA still has one more Delta IV Heavy rocket to launch from SLC-37 in March with a classified spy satellite for the National Reconnaissance Office. Once that launch is complete, ULA will wind down operations at SLC-37, and eventually turn over the facility back to the Space Force, which will look for a new tenant. For several months, industry sources have pointed to SpaceX as the leading contender to take over SLC-37 after ULA is finished with the launch pad.

But that’s not quite a done deal yet. Last year, a senior official at ULA told Ars on background that the company was also interested in maintaining a presence at SLC-37.

ULA’s new Vulcan rocket, which debuted last month and will replace the Delta IV and Atlas V launch vehicles, uses a different launch pad a few miles up the coast from SLC-37. ULA is upgrading and expanding its ground facilities at Cape Canaveral to ramp up the Vulcan launch cadence, and the ULA official told Ars the company may want to continue using a rocket processing hangar just south of the Delta IV launch pad for storage and horizontal processing of Vulcan rockets.

Details are scarce about everything SpaceX wants to do with SLC-37, but officials wrote on the environmental review website that SpaceX would “modify, reuse, or demolish the existing SLC-37 infrastructure to support Starship-Super Heavy launch and landing operations.”

This aerial view shows a United Launch Alliance Delta IV Heavy rocket awaiting liftoff from Space Launch Complex 37 at Cape Canaveral Space Force Station, Florida.

Enlarge / This aerial view shows a United Launch Alliance Delta IV Heavy rocket awaiting liftoff from Space Launch Complex 37 at Cape Canaveral Space Force Station, Florida.

The history of SLC-37 dates back to the 1960s, when NASA used the site for eight flights of the Saturn I and Saturn IB rockets to prepare for the Apollo program. The facility sat dormant for 30 years until Boeing moved in to ready SLC-37 for the Delta IV rocket, which has now flown 34 times from SLC-37. The launch pad currently includes a 330-foot-tall (100-meter) mobile gantry, a fixed erector, a fixed umbilical tower, and a flame trench for Delta IV missions.

Starship, the world’s largest rocket, would not need any of that that infrastructure, so if SpaceX takes over the pad, the facility will likely undergo extensive demolition and construction.

If SpaceX isn’t cleared to use SLC-37, the company could build a brand new launch pad designated Space Launch Complex 50. If this is the path SpaceX takes, SLC-50 would be built on undeveloped land north of SLC-37 and south of SpaceX’s primary launch pad for the Falcon 9 rocket at Space Launch Complex 40.

Goodbye to LC-49, hello to SLC-37

SpaceX’s interest in setting up shop at SLC-37 shows the company is getting serious about developing a second base for Starship on Florida’s Space Coast. In 2022, SpaceX constructed a launch tower and launch mount for Starship at Launch Complex 39A (LC-39A), located at NASA’s Kennedy Space Center. But the company made little progress there last year as teams focused on Starship test flights from South Texas.

Elon Musk, SpaceX’s founder and CEO, says Starship is the rocket that will make possible his dream of building a settlement on Mars. He has also touted Starship as a vehicle for point-to-point travel on Earth. Both stages of Starship are designed to be fully and rapidly reusable, with the Super Heavy booster and Starship upper stage returning to Earth for propulsive landings. Starship launch pads will double as landing pads.

Before any of those dreams are realized, Starship needs to get into orbit. The first two full-scale Starship test flights last year didn’t make it that far, but SpaceX got close on the second launch in November. SpaceX hopes to achieve a near-orbital mission with the third Starship test launch, perhaps as soon as early March.

Eventually, Musk envisions Starship launching multiple times per day on a variety of missions, carrying people, satellites, cargo, or refueling tankers into orbit. In order to do this, SpaceX will need a lot of launch and landing pads. SpaceX has toyed with the idea of floating offshore launch and landing platforms, but those plans are on hold.

In the near-term, SpaceX plans to build a second Starship launch tower at the company’s Starbase test site in Cameron County, Texas. There’s also the partially-built launch tower at LC-39A, and now SpaceX has set its sights on SLC-37.

SpaceX was previously looking at building another Starship launch pad from scratch on NASA property at the Kennedy Space Center. NASA environmental studies for this location, known as Launch Complex 49, kicked off in 2021. Patti Bielling, a NASA spokesperson, told Ars on Friday the agency is no longer working on Launch Complex 49.

“At this time, there are no activities involving LC-49 on Kennedy,” Bielling said. “Any previous activities regarding LC-49 were suspended, and no actions were taken.”

One of the first operational applications for Starship will be to serve as a human-rated lunar lander for NASA’s Artemis program. SpaceX is developing a version of Starship to ferry astronauts to and from the Moon’s surface, but in order for Starship to reach the Moon, it has to be refueled in low-Earth orbit. This will require perhaps 10 or more refueling flights using a version of Starship called a tanker, all launching in a matter of weeks. Those tanker flights will launch on Super Heavy boosters from pads in Texas and Florida.

In parallel with continued Starship test flights and demonstrating in-space refueling technology, SpaceX needs to build more launch pads to make all this possible. Although SpaceX has backpedaled on several of its Starship launch pad ideas, the company’s interest in SLC-37 suggests it still has big plans for Starship in Florida.

Welcome to Edition 6.31 of the Rocket Report! Photographers at Cape Canaveral, Florida, noticed a change to the spaceport’s skyline this week. Blue Origin has erected a full-size simulator of its New Glenn rocket vertically on its launch pad for a series of fit checks and tests. Late last year, we reported Blue Origin was serious about getting the oft-delayed New Glenn rocket off the ground by the end of 2024. This is a good sign of progress toward that goal, but there’s a long, long way to go. It was fun to watch preparations for the inaugural flights of a few other heavy-lift rockets in the last couple of years (Starship, SLS, and Vulcan). This year, it’s New Glenn.

Russia launches a classified satellite. On February 9, Russia launched its first orbital mission of the year with the liftoff of a Soyuz-2-1v rocket from the Plesetsk Cosmodrome in the far north of the country. The two-stage rocket delivered a classified satellite into orbit for the Russian military, Anatoly Zak of RussianSpaceWeb.com reports. In keeping with the Russian military’s naming convention, the satellite is known simply as Kosmos 2575, and there’s little indication about what it will do in space, except for one key fact.

But wait, there’s more … It turns out the launch of Kosmos 2575 occurred at exactly the same time of day as another Soyuz-2-1v rocket launched on December 27 with a Russian military satellite named Kosmos 2574. The newer spacecraft launched into the same orbital plane as Kosmos 2574, a strong indication that the two satellites have a shared mission. In recent years, Russia has tested rendezvous, proximity operations, and, at least in one instance, a projectile that would have applications for an anti-satellite weapon. You can be sure the US military and a global community of hobbyist satellite trackers will watch closely to see if these two satellites approach one another. If they do, they could continue technology demonstrations for an anti-satellite system. It’s unclear if the recent revelations regarding US officials’ concerns about Russian anti-satellite capabilities are related to these recent launches.

European startup testing methane-fueled rocket engine. Space transportation startup The Exploration Company has continued testing its methane-fueled Huracán engine, which will power an in-space and lunar transportation vehicle under development, European Spaceflight reports. Most recently, the Huracán engine completed another round of thrust chamber testing using liquid methane fuel as a coolant and tested a new thermal barrier coating. The methane/liquid oxygen engine is undergoing testing at a facility in Lampoldshausen, Germany, ahead of use on The Exploration Company’s Nyx Moon spacecraft, a transfer vehicle designed for transportation to and from cislunar space and also capable of Moon landings. The Nyx Moon is an evolution of a transfer vehicle the European startup is developing to ferry satellites between different orbits around Earth.

Other uses for Huracán… The Exploration Company appears to be positioning itself not only as a builder and operator of orbital and lunar transfer vehicles but also as a propulsion supplier to other space companies. In 2022, The Exploration Company received funding for the Huracán engine from the French government. At the time, the company described the engine as serving the needs of “the upper stages of small launchers and those of orbital vehicles.” (submitted by Ken the Bin)

Welcome to Edition 6.29 of the Rocket Report! Right now, SpaceX’s Falcon 9 rocket is the only US launch vehicle offering crew or cargo service to the International Space Station. The previous version of Northrop Grumman’s Antares rocket retired last year, forcing that company to sign a contract with SpaceX to launch its Cygnus supply ships to the ISS. And we’re still waiting on United Launch Alliance’s Atlas V (no fault of ULA) to begin launching astronauts on Boeing’s Starliner crew capsule to the ISS. Basically, it’s SpaceX or bust. It’s a good thing that the Falcon 9 has proven to be the most reliable rocket in history.

Virgin Galactic flies four passengers to the edge of space. Virgin Galactic conducted its first suborbital mission of 2024 on January 26 as the company prepares to end flights of its current spaceplane, Space News reports. The flight, called Galactic 06 by Virgin Galactic, carried four customers for the first time, along with its two pilots, on a suborbital hop over New Mexico aboard the VSS Unity rocket plane. Previous commercial flights had three customers on board, along with a Virgin Galactic astronaut trainer. The customers, which Virgin Galactic didn’t identify until after the flight, held US, Ukrainian, and Austrian citizenship.

Pending retirement … Virgin Galactic announced last year it would soon wind down flights of VSS Unity, citing the need to conserve its cash reserves for development of its next-generation Delta class of suborbital vehicles. Those future vehicles are intended to fly more frequently and at lower costs than Unity. After Galactic 06, Virgin Galactic said it will fly Unity again on Galactic 07 in the second quarter of the year with a researcher and private passengers. The company could fly Unity a final time later this year on the Galactic 08 mission. Since 2022, Virgin Galactic has been the only company offering commercial seats on suborbital spaceflights. The New Shepard rocket and spacecraft from competitor Blue Origin hasn’t flown people since a launch failure in September 2022. (submitted by Ken the Bin)

Iran launches second rocket in eight days. Iran launched a trio of small satellites into low-Earth orbit on January 28, Al Jazeera reports. This launch used Iran’s Simorgh rocket, which made its first successful flight into orbit after a series of failures dating back to 2017. The two-stage, liquid-fueled Simorgh rocket deployed three satellites. The largest of the group, named Mehda, was designed to measure the launch environments on the Simorgh rocket and test its ability to deliver multiple satellites into orbit. Two smaller satellites will test narrowband communication and geopositioning technology, according to Iran’s state media.

Back to back … This was a flight of redemption for the Simorgh rocket, which is managed by the civilian-run Iranian Space Agency. While the Simorgh design has repeatedly faltered, the Iranian military’s Islamic Revolutionary Guard Corps has launched two new orbital-class rockets in recent years. The military’s Qased launch vehicle delivered small satellites into orbit on three successful flights in 2020, 2022, and 2023. Then, on January 20, the military’s newest rocket, named the Qaem 100, put a small remote-sensing payload into orbit. Eight days later, the Iranian Space Agency finally achieved success with the Simorgh rocket. Previously, Iranian satellite launches have been spaced apart by at least several months.

Rocket Lab’s first launch of 2024. Rocket Lab was back in action on January 31, kicking off its launch year with a recovery Electron mission from New Zealand. This was its second return-to-flight mission following a mishap late last year, Spaceflight Now reports. Rocket Lab’s Electron rocket released four Space Situational Awareness (SSA) satellites into orbit for Spire Global and NorthStar Earth & Space. Peter Beck, Rocket Lab’s founder and CEO, said in a statement that the company has more missions on the books for 2024 than in any year before. Last year, Rocket Lab launched 10 flights of its light-class Electron launcher.

Another recovery … Around 17 minutes after liftoff, the Electron’s first-stage booster splashed down in the Pacific Ocean under parachute. A recovery vessel was stationed nearby downrange from the launch base at Mahia Peninsula, located on the North Island of New Zealand. Rocket Lab has ambitions of re-flying a first stage booster in its entirety. Last August, it demonstrated partial reuse with the re-flight of a Rutherford engine salvaged from a booster recovered on a prior mission. (submitted by Ken the Bin)

PLD Space wins government backing. PLD Space has won the second and final round of a Spanish government call to develop sovereign launch capabilities, European Spaceflight reports. Spain’s Center for Technological Development and Innovation announced on January 26 that it selected PLD Space, which is developing a small launch vehicle called Miura 5, to receive a 40.5-million euro loan from a government fund devoted to aiding the Spanish aerospace sector, with a particular emphasis on access to space. Last summer, the Spanish government selected PLD Space and Pangea Aerospace to each receive 1.5 million euros in a preliminary funding round to mature their designs. PLD Space won the second round of the loan competition.

Moving toward Miura 5 … “The technical decision in favor of PLD Space confirms that our technological development strategy is sound and is based on a solid business plan,” said Ezequiel Sanchez, PLD Space’s executive president. “Winning this public contract to create a strategic national capability reinforces our position as a leading company in securing Europe’s access to space.” Miura 5 will be capable of launching about a half-ton of payload mass into low-Earth orbit and is scheduled to make its debut launch from French Guiana in late 2025 or early 2026, followed by the start of commercial operations later in 2026. PLD Space will need to repay the loan through royalties over the first 10 years of the commercial operation of Miura 5. (submitted by Leika)

The Starlab commercial space station will launch on SpaceX’s Starship rocket, officials said this week.

Starlab is a joint venture between the US-based Voyager Space and the European-based multinational aerospace corporation Airbus. The venture is building a large station with a habitable volume equivalent to half the pressurized volume of the International Space Station and will launch the new station no earlier than 2028.

“SpaceX’s history of success and reliability led our team to select Starship to orbit Starlab,” Dylan Taylor, chairman and CEO of Voyager Space, said in a statement. “SpaceX is the unmatched leader for high-cadence launches and we are proud Starlab will be launched to orbit in a single flight by Starship.”

Fitting in a big fairing

Starlab will have a diameter of about 26 feet (8 meters). It is perhaps not a coincidence that Starship’s payload bay can accommodate vehicles up to 26 feet across in its capacious fairing. However, in an interview, Marshall Smith, the chief technology officer of Voyager Space, said the company looked at a couple of launch options.

“We looked at multiple launches to get Starlab into orbit, and eventually gravitated toward single launch options,” he said. “It saves a lot of the cost of development. It saves a lot of the cost of integration. We can get it all built and checked out on the ground, and tested and launch it with payloads and other systems. One of the many lessons we learned from the International Space Station is that building and integrating in space is very expensive.”

With a single launch on a Starship, the Starlab module should be ready for human habitation almost immediately, Smith said.

It's hard to believe the interior of Starlab will ever be this clean in space.

Starlab is one of several privately developed space stations vying to become a commercial replacement for the International Space Station, which NASA is likely to retire in 2030. Among the other contenders are Axiom Space, Blue Origin, and Vast Space. SpaceX may also configure a human-rated version of Starship as a temporary space station.

NASA has provided seed funding to some of these companies, including Voyager Space, to begin designing and developing their stations. NASA is expected to hold a second round of competition next year, when it will select one or more companies to proceed with building and testing their stations.

Finding customers

Each company is developing a space station that will serve both government customers—NASA wants to continue flying at least a handful of astronauts in low-Earth orbit for research purposes—as well as private customers. The challenge for Starlab and other commercial stations is developing a customer base beyond NASA to support the expense of flying and operating stations.

The challenge is a huge one: NASA spent more than $100 billion constructing the International Space Station and has a $3 billion annual budget for operations and transportation of people and supplies to the station. The agency is likely to fund commercial space stations at a level of about $1 billion a year, so these companies must build their facilities relatively quickly at low cost and then find a diverse base of customers to offset expenses.

Starlab may have an advantage in this regard with its co-ownership by Airbus. One of the big questions surrounding the end of the International Space Station is what happens to the European astronauts who fly there now. The European Space Agency will likely be reticent about funding missions to private space stations owned and operated by US companies. The involvement by Airbus, therefore, makes Starlab attractive to European nations as a destination.

Welcome to Edition 6.27 of the Rocket Report! This week, we discuss an intriguing new report looking at Starship. Most fascinating, the report covers SpaceX’s costs to build a Starship and how these costs will come down as the company ramps up its build and launch cadence. At the other end of the spectrum, former NASA Administrator Mike Griffin has a plan to get astronauts back to the Moon that would wholly ignore the opportunities afforded by Starship.

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).

The problem at America’s military spaceports. The Biden administration is requesting $1.3 billion over the next five years to revamp infrastructure at the Space Force’s ranges in Florida and California, Ars reports. This will help address things like roads, bridges, utilities, and airfields that, in many cases, haven’t seen an update in decades. But it’s not enough, according to the Space Force. Last year, Cape Canaveral was the departure point for 72 orbital rocket launches, and officials anticipate more than 100 this year. The infrastructure and workforce at the Florida spaceport could support about 150 launches in a year without any major changes, but launch activity is likely to exceed that number within a few years.

Higher fees incoming … Commercial launch companies operating from Cape Canaveral Space Force Station, Florida, or Vandenberg Space Force Base, California, pay fees to the Space Force to reimburse for direct costs related to rocket launches. These cover expenses like weather forecast services, surveillance to ensure airplanes and boats stay out of restricted areas, and range safety support. “What that typically meant was anything we did that was specifically dedicated to that launch,” said Col. James Horne, deputy commander of the Space Force’s assured access to space directorate. This is about to change after legislation passed by Congress in December allows the Space Force to charge indirect fees to commercial providers. This money will go into a fund to pay for maintenance and upgrades to infrastructure used by all launch companies at the spaceports.

Momentus is running out of money. Momentus, a company that specializes in “last mile” satellite delivery services, announced on January 12 that it is running out of money and does not have a financial lifeline, CNBC reports. The company was once valued at more than $1 billion before going public via a Special Purpose Acquisition Company (SPAC) in 2021 but now has a market capitalization of less than $10 million. Momentus has developed a space tug called Vigoride, designed to place small satellites into bespoke orbits after deploying from a larger rocket on a rideshare mission, such as a SpaceX Falcon 9. Now, Momentus is abandoning plans for its next mission that was due for launch in March. In December, the company laid off about 20 percent of its workforce to reduce costs.

Fatal blow? … Momentus may have received a potentially fatal blow after losing the US Space Development Agency’s recent competition for 18 so-called Tranche 2 satellites, Aviation Week reports. Instead, the SDA made recent satellite manufacturing contract awards to Rocket Lab, L3Harris, Lockheed Martin, and Sierra Space. On Wednesday, Momentus announced it closed a $4 million stock sale. This should keep Momentus afloat for a while longer but won’t provide the level of capital needed to undertake any significant manufacturing or technical development work. (submitted by Ken the Bin)

Orbex may go bigger. UK-based launch startup Orbex hasn’t yet flown its small satellite launcher, called Prime, but is already looking at what’s next, according to reports by European Spaceflight and the Financial Times. New Orbex CEO Phil Chambers, who was officially appointed earlier this month, told the Financial Times that the company was already discussing the possibility of developing a larger vehicle. Speaking to European Spaceflight, Chambers described the business model to deliver orbital launch services with Prime as “robust.” Despite this, he admitted that the small launch industry was only a small sliver of the overall launch market.

Learning to walk before running … While future growth is on Orbex’s radar, its near-term focus is completing construction of a spaceport in Scotland, launching a maiden flight of Prime, and delivering on the six flights the company has already sold. The two-stage Prime rocket, fueled by “bio-propane,” will be capable of hauling a payload of approximately 180 kilograms (nearly 400 pounds) into low-Earth orbit. But Orbex has been shy about releasing updates on the progress of the Prime rocket’s development since unveiling a full-scale mock-up of the launch vehicle in 2022. Last year, the CEO who led Orbex since its founding resigned. Its most recent significant funding round was valued at 40.4 million pounds in late 2022. (submitted by Ken the Bin)

SpaceX

It’s no secret that Elon Musk has big ambitions for SpaceX’s Starship mega-rocket. This is the vehicle that, with plenty of permutations and upgrades, Musk says will ferry cargo and people across the Solar System to build a settlement on Mars, making humanity a multi-planetary species and achieving the billionaire’s long-standing dream.

Of course, that is a long way off. SpaceX is still working on getting Starship into orbit or close to it, an achievement that appears to be possible this year. Then, the company will start launching Starlink satellites on Starship missions while testing in-space refueling technology needed to turn Starship into a human-rated Moon lander for NASA.

SpaceX’s South Texas team is progressing toward the third full-scale Starship test flight. On December 20, the Starship’s upper stage slated for the next test flight completed a test-firing of its Raptor engines at the Starbase launch site on the Texas Gulf Coast. Nine days later, the 33-engine Super Heavy booster fired up on the launch pad for its own static fire test. On the same day, SpaceX hot-fired the Starship upper stage once again on a test stand next to the launch pad.

With those milestones complete, ground teams rolled the booster back to its hangar for final preflight checks and reconfigurations. The ship, too, will need to be rolled back to its high bay.

SpaceX could be weeks away from having both vehicles ready to fly, but the company hasn’t released an update on lessons learned from the previous Starship test flight in November. That flight was largely successful, with apparently flawless performance from the 33 engines on the Super Heavy booster during launch. The Starship upper stage reached space before self-destructing downrange over the Gulf of Mexico. The booster exploded during a maneuver to bring itself back to Earth for a controlled splashdown at sea.

The company’s engineers will want to understand and correct whatever caused those issues. The Federal Aviation Administration then needs to approve SpaceX’s investigation into the last Starship flight before issuing a new commercial launch license. When it flies again, Starship will try to reach near orbital velocity, enough speed to travel most of the way around the world before reentering the atmosphere near Hawaii.

Verifying the performance of Starship’s heat shield tiles during reentry will be valuable learning for SpaceX, but Starship first needs to be fully successful with a launch. This is just the start for the privately funded Starship program.
