There was a panel discussion at a space conference in Singapore 11 years ago that has since become legendary in certain corners of the space industry for what it reveals about European attitudes toward upstart SpaceX.

The panel included representatives from a handful of launch enterprises, including Europe-based Arianespace, and the US launch company SpaceX. At one point during the discussion, the host asked the Arianespace representative—its chief of sales in Southeast Asia, Richard Bowles—how the institutional European company would respond to SpaceX’s promise of lower launch costs and reuse with the Falcon 9 rocket.

“What I’m discovering in the market is that SpaceX primarily seems to be selling a dream, which is good. We should all dream,” Bowles replied. “I think a $5 million launch or a $15 million launch is a bit of a dream. Personally, I think reusability is a dream. How am I going to respond to a dream? My answer to respond to a dream is, first of all, you don’t wake people up.”

To be fair to Bowles, at the time of his remarks, SpaceX had only launched the Falcon 9 five times by the middle of 2013. But his condescension was nevertheless something to behold.

Later in the discussion, Bowles added that he did not believe launching 100 times a year, something that SpaceX was starting to talk about, was “realistic.” Then, in a moment of high paternalism, he turned to the SpaceX official on the panel and said, “You shouldn’t present things that are not realistic.”

In response, Barry Matsumori, a senior vice president at SpaceX, calmly said he would let his company’s response come through its actions.

Actions do speak louder than words

Eleven years later, of course, SpaceX is launching more than 100 times a year. The company’s internal price for launching a Falcon 9 is significantly less than $20 million. And all of this is possible through the reuse of the rocket’s first stage and payload fairings, each of which have now proven capable of flying 20 or more times.

One might think that, in the decade since, European launch officials would have learned their lesson. After all, last year, the continent had to resort to launching its valuable Euclid Space Telescope on a Falcon 9 rocket. This year, because the new European Ariane 6 rocket was not yet ready after myriad delays, multiple Galileo satellites have been launched and will be launched on the Falcon 9 rocket.

Some officials have taken note. In a candid commentary last year, European Space Agency chief Josef Aschbacher acknowledged that the continent faced an “acute” launcher crisis amid the Ariane 6 delays and the rise of SpaceX as a launch competitor. “SpaceX has undeniably changed the launcher market paradigm as we know it,” Aschbacher wrote. “With the dependable reliability of Falcon 9 and the captivating prospects of Starship, SpaceX continues to totally redefine the world’s access to space, pushing the boundaries of possibility as they go along.”

But not everyone got the message, it seems.

Next month, the Ariane 6 rocket should finally make its debut. It will probably be successful. Europe has excellent technical capabilities in regard to launch. But from day one, the Ariane 6 launch vehicle will cost significantly more than the Falcon 9 rocket, which has similar capabilities, and offer no provision for reuse. Certainly, it will meet Europe’s institutional needs. But it likely will not shake up the market, nor realistically compete with a fully reusable Falcon 9.

Who really needs to be woken up?

And what about Starship? If and when SpaceX can deliver it to the market, the next-generation rocket will offer a fully reusable booster with five times the lift capacity of the Ariane 6 rocket for half its cost or less. How can Europe hope to compete with that? The European Space Agency’s director of space transportation, Toni Tolker-Nielsen—who works for Aschbacher, it should be noted—said he’s not concerned.

“Honestly, I don’t think Starship will be a game-changer or a real competitor,” he said in an interview with Space News. “This huge launcher is designed to fly people to the Moon and Mars. Ariane 6 is perfect for the job if you need to launch a four- or five-ton satellite. Starship will not eradicate Ariane 6 at all.”

In one sense, Tolker-Nielsen is correct. Starship will not change how Europe gets its small and medium-sized satellites into space. Made and launched in Europe, the Ariane 6 rocket will be a workhorse for the continent. Indeed, some European officials are going so far as to press for legislation mandating that European satellites launch on European rockets.

But to say Starship will not be a game-changer represents the same head-in-the-sand attitude displayed by Bowles a decade ago with his jokes about not waking the deluded dreamers up. In hindsight, it’s clear that the dreamers were not SpaceX or its customers. Rather, they were European officials who had lulled themselves into thinking their dominance in commercial launch would persist without innovation.

While they slumbered, these officials ignored the rise of reusability. They decided the Ariane 6 rocket should look like its expendable predecessors, with solid rocket boosters. Meanwhile, following the rise of the Falcon 9, nearly all new rocket projects have incorporated a significant reusability component. It’s no longer just SpaceX founder Elon Musk saying companies need to pursue reuse or perish. Almost everyone is.

Perhaps someone should wake Tolker-Nielsen up.

SpaceX is about to launch Starship again—the FAA will be more forgiving this time

SpaceX

The Federal Aviation Administration approved the commercial launch license for the fourth test flight of SpaceX’s Starship rocket Tuesday, with liftoff from South Texas targeted for just after sunrise Thursday.

“The FAA has approved a license authorization for SpaceX Starship Flight 4,” the agency said in a statement. “SpaceX met all safety and other licensing requirements for this test flight.”

Shortly after the FAA announced the launch license, SpaceX confirmed plans to launch the fourth test flight of the world’s largest rocket at 7: 00 am CDT (12: 00 UTC) Thursday. The launch window runs for two hours.

This flight follows three prior demonstration missions, each progressively more successful, of SpaceX’s privately developed mega-rocket. The last time Starship flew—on March 14—it completed an eight-and-a-half minute climb into space, but the ship was unable to maneuver itself as it coasted nearly 150 miles (250 km) above Earth. This controllability problem caused the rocket to break apart during reentry.

On Thursday’s flight, SpaceX officials will expect the ascent portion of the test flight to be similarly successful to the launch in March. The objectives this time will be to demonstrate Starship’s ability to survive the most extreme heating of reentry, when temperatures peak at 2,600° Fahrenheit (1,430° Celsius) as the vehicle plunges into the atmosphere at more than 20 times the speed of sound.

SpaceX officials also hope to see the Super Heavy booster guide itself toward a soft splashdown in the Gulf of Mexico just offshore from the company’s launch site, known as Starbase, in Cameron County, Texas.

“The fourth flight test turns our focus from achieving orbit to demonstrating the ability to return and reuse Starship and Super Heavy,” SpaceX wrote in an overview of the mission.

Last month, SpaceX completed a “wet dress rehearsal” at Starbase, where the launch team fully loaded the rocket with cryogenic methane and liquid oxygen propellants. Before the practice countdown, SpaceX test-fired the booster and ship at the launch site. More recently, technicians installed components of the rocket’s self-destruct system, which would activate to blow up the rocket if it flies off course.

Then, on Tuesday, SpaceX lowered the Starship upper stage from the top of the Super Heavy booster, presumably to perform final touch-ups to the ship’s heat shield, composed of 18,000 hexagonal ceramic tiles to protect its stainless-steel structure during reentry. Ground teams were expected to raise the ship, or upper stage, back on top of the booster sometime Wednesday, returning the rocket to its full height of 397 feet (121 meters) ahead of Thursday morning’s launch window.

The tick-tock of Starship’s fourth flight

If all goes according to plan, SpaceX’s launch team will start loading 10 million pounds of super-cold propellants into the rocket around 49 minutes before liftoff Thursday. The methane and liquid oxygen will first flow into the smaller tanks on the ship, then into the larger tanks on the booster.

The rocket should be fully loaded about three minutes prior to launch, and, following a sequence of automated checks, the computer controlling the countdown will give the command to light the booster’s 33 Raptor engines. Three seconds later, the rocket will begin its vertical climb off the launch mount, with its engines capable of producing more than 16 million pounds of thrust at full power.

Heading east from the Texas Gulf Coast, the rocket will exceed the speed of sound in about a minute, then begin shutting down its 33 main engines around 2 minutes and 41 seconds after liftoff. Then, just as the Super Heavy booster jettisons to begin a descent back to Earth, Starship’s six Raptor engines will ignite to continue pushing the upper portion of the rocket into space. Starship’s engines are expected to burn until T+ 8 minutes, 23 seconds, accelerating the rocket to near-orbital velocity with enough energy to fly an arcing trajectory halfway around the world to the Indian Ocean.

All of this will be similar to the events of the last Starship launch in March. What differs in the flight plan this time involves the attempts to steer the booster and ship back to Earth. This is important to lay the groundwork for future flights, when SpaceX wants to bring the Super Heavy booster—the size of the fuselage of a Boeing 747 jumbo jet—to a landing back at its launch pad. Eventually, SpaceX also intends to recover reusable Starships back at Starbase or other spaceports.

This infographic released by SpaceX shows the flight profile for SpaceX's fourth Starship launch.

SpaceX

Based on the results of the March test flight, SpaceX still has a lot to prove in these areas. On that flight, the engines on the Super Heavy booster could not complete all the burns required to guide the rocket toward the splashdown zone in the Gulf of Mexico. The booster lost control as it plummeted toward the ocean.

Engineers traced the failure to blockage in a filter where liquid oxygen flows into the Raptor engines. Notably, a similar problem occurred on the second Starship test flight last November. The Super Heavy booster awaiting launch Thursday has additional hardware to improve propellant filtration capabilities, according to SpaceX. The company also implemented “operational changes” on the booster for the upcoming test flight, including to jettison the Super Heavy’s staging ring, which sits between the booster and ship during launch, to reduce the rocket’s mass during descent.

SpaceX has a lot of experience bringing back its fleet of Falcon 9 boosters. The company now boasts a streak of more than 240 successful rocket landings in a row, so it’s reasonable to expect SpaceX will overcome the challenge of recovering the larger Super Heavy booster.

Welcome to Edition 6.46 of the Rocket Report! It looks like we will be covering the crew test flight of Boeing’s Starliner spacecraft and the fourth test flight of SpaceX’s giant Starship rocket over the next week. All of this is happening as SpaceX keeps up its cadence of flying multiple Starlink missions per week. The real stars are the Ars copy editors helping make sure our stories don’t use the wrong names.

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.

Another North Korean launch failure. North Korea’s latest attempt to launch a rocket with a military reconnaissance satellite ended in failure due to the midair explosion of the rocket during the first-stage flight this week, South Korea’s Yonhap News Agency reports. Video captured by the Japanese news organization NHK appears to show the North Korean rocket disappearing in a fireball shortly after liftoff Monday night from a launch pad on the country’s northwest coast. North Korean officials acknowledged the launch failure and said the rocket was carrying a small reconnaissance satellite named Malligyong-1-1.

Russia’s role? … Experts initially thought the pending North Korean launch, which was known ahead of time from international airspace warning notices, would use the same Chŏllima 1 rocket used on three flights last year. But North Korean statements following the launch Monday indicated the rocket used a new propulsion system burning a petroleum-based fuel, presumably kerosene, with liquid oxygen as the oxidizer. The Chŏllima 1 rocket design used a toxic mixture of hypergolic hydrazine and nitrogen tetroxide as propellants. If North Korea’s statement is true, this would be a notable leap in the country’s rocket technology and begs the question of whether Russia played a significant role in the launch. Last year, Russian President Vladimir Putin pledged more Russian support for North Korea’s rocket program in a meeting with North Korean leader Kim Jong Un. (submitted by Ken the Bin and Jay500001)

Rocket Lab deploys small NASA climate satellite. Rocket Lab is in the midst of back-to-back launches for NASA, carrying identical climate research satellites into different orbits to study heat loss to space in Earth’s polar regions. The Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE) satellites are each about the size of a shoebox, and NASA says data from PREFIRE will improve computer models that researchers use to predict how Earth’s ice, seas, and weather will change in a warming world. “The difference between the amount of heat Earth absorbs at the tropics and that radiated out from the Arctic and Antarctic is a key influence on the planet’s temperature, helping to drive dynamic systems of climate and weather,” NASA said in a statement.

Twice in a week… NASA selected Rocket Lab’s Electron launch vehicle to deliver the two PREFIRE satellites into orbit on two dedicated rides rather than launching at a lower cost on a rideshare mission. This is because scientists want the satellites flying at the proper alignment to ensure they fly over the poles several hours apart, providing the data needed to measure how the rate at which heat radiates from the polar regions changes over time. The first PREFIRE launch occurred on May 25, and the next one is slated for May 31. Both launches will take off from Rocket Lab’s base in New Zealand. (submitted by Ken the Bin)

A rocket launch comes to Rizhao. China has diversified its launch sector over the last decade to include new families of small satellite launchers and new spaceports. One of these relatively new small rockets, the solid-fueled Ceres 1, took off Wednesday from a floating launch pad positioned about 2 miles (3 km) off the coast of Rizhao, a city of roughly 3 million people in China’s Shandong province. The Ceres 1 rocket, developed by a quasi-commercial company called Galactic Energy, has previously flown from land-based launch pads and a sea-borne platform, but this mission originated from a location remarkably close to shore, with the skyline of a major metropolitan area as a backdrop.

Range safety … There’s no obvious orbital mechanics reason to position the rocket’s floating launch platform so near a major Chinese city, other than perhaps to gain a logistical advantage by launching close to port. The Ceres 1 rocket has a fairly good reliability record—11 successes in 12 flights—but for safety reasons, there’s no Western spaceport that would allow members of the public (not to mention a few million) to get so close to a rocket launch. For decades, Chinese rockets have routinely dropped rocket boosters containing toxic propellant on farms and villages downrange from the country’s inland spaceports.

IFT-4 on June 5 —

Clearing blocked filters and clogged valves is the order of the day.

SpaceX's Starship vehicle undergoes a wet dress rehearsal prior to its fourth launch attempt.

SpaceX

SpaceX is targeting June 5 for the next flight of its massive Starship rocket, the company said Friday.

The highly anticipated test flight— the fourth in a program to bring Starship to operational readiness and make progress toward its eventual reuse—will seek to demonstrate the ability of the Super Heavy first stage to make a soft landing in the Gulf of Mexico and for the Starship upper stage to make a controlled reentry through Earth’s atmosphere before it falls into the Indian Ocean.

This mission will carry no payloads as SpaceX seeks additional flight data about the performance of the complex Starship vehicle. It is simultaneously the largest and most powerful rocket ever built and the first launch system ever intended to be fully and rapidly reusable.

As part of its announcement of the flight date, SpaceX provided some information about its learnings from the most recent flight test, Flight 3, which launched on March 14, 2024.

Dissecting Flight 3

During that flight, SpaceX also attempted a soft landing of the Super Heavy first stage. After its separation from the Starship upper stage, as intended, 13 of Super Heavy’s 33 Raptor engines successfully relit to make a controlled flight through the lower atmosphere. During this boostback burn, however, six of these engines shut down early. Later in the descent, as the rocket neared the sea surface, the rocket was supposed to use the same 13 engines to make a final landing burn.

“The six engines that shut down early in the boostback burn were disabled from attempting the landing burn startup, leaving seven engines commanded to start up with two successfully reaching mainstage ignition,” the company said in its recap of the flight. “The booster had lower than expected landing burn thrust when contact was lost at approximately 462 meters in altitude over the Gulf of Mexico and just under seven minutes into the mission.”

The cause of this failure was traced to blockage in a filter where liquid oxygen flows into the Raptor engines. Notably, a similar problem occurred during the second test flight of Starship in November 2023. SpaceX says it implemented “hardware changes” to address this blockage issue for the third test flight. Now, the company said, “Super Heavy boosters for Flight 4 and beyond will get additional hardware inside oxygen tanks to further improve propellant filtration capabilities.” It will be interesting to see whether the company’s engineers have successfully addressed this issue.

As for the Starship upper stage, the vehicle began losing the ability to control its attitude during its coast phase in space. This was found to be due to clogged valves used by reaction control thrusters on the upper stage. The company’s update notes that “SpaceX has since added additional roll control thrusters on upcoming Starships.” But it is not clear that they will be available for Flight 4. Indeed, the fact that SpaceX is not attempting an in-flight relight of Raptor engines on the Starship upper stage suggests these new roll control thrusters are not yet in place.

Ultimately this lack of attitude control during Flight 3 resulted in a non-nominal reentry to Earth’s atmosphere. SpaceX was able to maintain contact with the vehicle down to 65 km in altitude before telemetry was lost due to excess heating.

Back to the basics

On Flight 3, SpaceX achieved some important milestones, including the opening of the Starship payload bay door in space and a small propellant transfer demonstration. Due to the loss of attitude control, however, a planned Raptor rocket engine re-light test was not conducted. This is an important test, as Raptor ignition is needed to perform a controlled reentry—essentially to ensure that Starship returns to a remote section of ocean rather than land.

For the next flight, SpaceX is focused on solving the technical issues observed on Flight 3: the filter blockages observed during Super Heavy’s boostback and landing burns, Starship’s attitude control during its coast phase, and managing reentry of that vehicle from orbital velocity.

Once these issues are resolved, the company can proceed to more advanced tests, including landing the Super Heavy booster back at the South Texas launch site, deployment of Starlink satellites, and additional tests of propellant transfer essential for NASA’s Artemis Program to land humans on the Moon.

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.

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

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.

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)

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.
