SpaceX successfully launches and lands Starship and Superheavy

7:20 am

Damaged but working flap on Starship
Damaged but working flap on Starship

SpaceX this morning successfully launched and landed both Starship and Superheavy in the ocean, with both vehicles splashing down in a vertical position as planned.

Some quick details:

  • One engine on Superheavy failed during launch, but the vehicle completed its job, successfully releasing Starship as planned.
  • Superheavy then completed a controlled splashdown in the Gulf of Mexico, landing softly and vertically. It then tipped over into the water as planned. At this moment it is unclear how successful it was in landing precisely at its planned location. One engine during the landing burn failed.
  • Unlike the previous test, Starship flew under control for its entire flight, even though the camera view showed a flap actually begin breaking up.
  • That flap, despite damage, appeared to function through landing. The screen capture to the right was taken just before landing, as the flap adjusted its position despite the significant damage near its attachment point to the ship.
  • It appeared that Starship successfully completed its flip to vertical just before landing.
  • At landing it was unclear if the landing burn occurred as planned. It did appear the spacecraft splashed down softly, and the controllers announced the burn occurred, but the indicators on the screen showed no engine burn.

Overall, this launch was an incredible success. Based on the results, the fifth test flight should be approved by the FAA relatively quickly. The FAA’s responsibility is supposed to be limited to just issues of safety. As long as SpaceX demonstrates the rocket landed where it was intended, the FAA has no cause to delay future approvals.

If so, the next launch could occur very quickly, as the next prototypes are ready and waiting. We could see another launch within two months, at the most. I predict late July, though it could be a bit later if SpaceX engineers need more time to analyze what happened to Starship during descent and then apply that knowledge to the next prototype.

UPDATE: China also had a successful launch this morning. Pseudo-company Galactic Energy’s Ceres-1 rocket placed three satellites into orbit, lifting off from the Jiuquan spaceport in the northwest of China.

Little information was released by China’s state-run press, which didn’t even bother to mention the pseudo-company’s name in its report. The solid-fueled lower stages landed somewhere inside China, but we have no idea where or how close to habitable areas.

The leaders in the 2024 launch race:

60 SpaceX
27 China
8 Russia
7 Rocket Lab

American private enterprise now leads the world combined in successful launches, 70 to 41, while SpaceX by itself leads the entire world, including other American companies, 60 to 51.

Note that for context the U.S. total at this moment, 70 launches and achieved in less than half a year, matches the nation’s previous annual record set in 1966 and held until 2022.

Firefly gets a major 25-launch contract from Lockheed Martin

9:02 pm

Firefly today announced that Lockheed Martin has awarded it a launch contract for 25 launches through 2029.

The contract “commits Lockheed Martin to 15 launch reservations and 10 optional launches.”

What is interesting about this agreement is who Lockheed did not give the launches to. Lockheed Martin has been a major investor in Rocket Lab, which is about to complete its 50th operational launch. It also has been a major investor in the rocket startup ABL, which in 2021 Lockheed Martin awarded its own giant launch contract for 58 launches through 2029.

ABL however has not yet had a successful launch. It tried twice in 2022, but has done nothing since. It could very well be that this new contract for Firefly is a signal that Lockheed Martin has lost faith in ABL, that there are more fundamental problems in that company. Those problems could also be related to the new regulatory burdens from the FAA that in the past two years appear to have slowed development by all American rocket startups.

That Lockheed Martin did not give this contract to Rocket Lab, which is flying, could be because Lockheed is trying to encourage the development of multiple small satellite launchers, in order to provide its main satellite-making business a variety of good options.

Either way, this deal strengthens Firefly’s position, even though its Alpha rocket has only had two launches (in 2022 and 2023), both of which put the payloads in orbit but failed to place them in the correct orbit. Moreover, the company has said it would launch four times in 2024, and as yet to launch once.

ESA schedules first Ariane-6 launch for July 9, 2024

10:07 am

After years of delays and technical problems the European Space Agency (ESA) today announced that it has finally scheduled the first Ariane-6 launch, now to take place on July 9, 2024 from French Guiana.

The press release at the link tries to paint a glowing future for Ariane-6, as illustrated by this quote from Stéphane Israël, CEO of Arianespace.

“With 30 missions in our order book, Ariane 6 has already gained the trust of institutional and commercial customers. We are preparing to make Ariane 6’s second launch by the end of the year, followed by a steady rise to around ten launches a year once we reach cruising speed. It represents a splendid challenge for Arianespace and our partners.”

The simple fact is that Ariane-6 costs too much to launch and is not competitive with the new generation of reuseable rockets. If Amazon’s management had not decided to give it a big launch contract (in order to avoid giving that money to SpaceX), it would have very few payloads to launch. Once those launches are completed expect Ariane-6 to go the way of the dodo and the buggy whip, replaced by a new fleet of competing private European rocket companies capable of doing things faster and cheaper.

ULA’s Atlas-5 launches Boeing’s Starliner capsule on its first manned mission

9:17 am

After many delays and scrubs involving both the rocket and the capsule, ULA’s Atlas-5 rocket today successfully launched Boeing’s Starliner capsule on its first manned mission, carrying NASA astronauts Butch Wilmore and Suni Williams.

I have embedded the live stream below, cued to just before liftoff. The spacecraft will dock with ISS tomorrow, where Wilmore and Williams will spend a week checking out the capsule’s operations before undocking and returning to Earth.

As this was only the third launch this year for ULA, the leader board for the 2024 launch race doesn’t change:

59 SpaceX
26 China
8 Russia
7 Rocket Lab

American private enterprise now leads the world combined in successful launches, 69 to 40, while SpaceX by itself leads the entire world, including other American companies, 59 to 50.

SpaceX and Rocket Lab complete successful launches

8:45 pm

This evening both SpaceX and Rocket Lab completed launches only about an hour apart but on opposite sides of the world.

First, SpaceX this evening successfully launched another 20 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its 20th flight, landing safely on a drone ship in the Atlantic.

Next, Rocket Lab completed the second to two launches for NASA, placing the second Prefire climate satellite into orbit, following the first launch on May 25, 2024. Its Electron rocket lifted off from Rocket Lab’s launchpad in New Zealand.

The leaders in the 2024 launch race:

59 SpaceX
26 China
8 Russia
7 Rocket Lab

American private enterprise now leads the world combined in successful launches, 68 to 40, while SpaceX by itself leads the entire world, including other American companies, 59 to 49.

FAA issues launch license for the fourth test orbital launch of Starship/Superheavy

3:10 pm

FAA today issued [pdf] the launch license for SpaceX’s fourth test orbital launch of Starship/Superheavy, effective June 4, 2024, thus allowing the company to proceed with its planned June 6, 2024 launch date.

The two-hour launch window opens at 7 am (Central). SpaceX’s live stream will begin 30 minutes earlier. From SpaceX’s Starship website:

The fourth flight test turns our focus from achieving orbit to demonstrating the ability to return and reuse Starship and Super Heavy. The primary objectives will be executing a landing burn and soft splashdown in the Gulf of Mexico with the Super Heavy booster, and achieving a controlled entry of Starship.

To accomplish this, several software and hardware upgrades have been made to increase overall reliability and address lessons learned from Flight 3. The SpaceX team will also implement operational changes, including the jettison of the Super Heavy’s hot-stage following boostback to reduce booster mass for the final phase of flight.

Flight 4 will fly a similar trajectory as the previous flight test, with Starship targeted to splashdown in the Indian Ocean. This flight path does not require a deorbit burn for reentry, maximizing public safety while still providing the opportunity to meet our primary objective of a controlled Starship reentry.

This FAA approval is wonderful news, considering the red-tape delays the agency has previously caused to SpaceX’s efforts. It suggests that officials there are trying hard to speed up their paperwork. If so, the gap between this flight and fifth might be shorter than the three month gap seen between the third flight in March and this flight on June 6th.

ESA requests information from European rocket startups

9:16 am

The European Space Agency (ESA) has released a request for information from European rocket startups to outline their capabilities and plans so that ESA can assess whether they qualify for future launch contracts.

Currently, ESA is working towards publishing a competitive tender in early 2025 for the award of contracts to allow European launch providers to demonstrate their ability to provide the capacity to serve institutional mission needs. To better define this competitive tender and align the challenge in the best possible way to incentivize providers, ESA has published a Request for Information call. “This Campaign will let economic operators express their views and expectations on the future of European access to space and actively participate in the definition of the European Launcher Challenge,” explains the call.

The call is limited to companies in Europe. The information the companies provide will then be used by ESA to shape the actual contract offers in 2025. The long term goal is for independent and competing European rocket companies to replace the Ariane-6, and provide a fleet of rockets of all types capable of launching European payloads faster and for much less money.

French startup captures Russian satellite maneuvering close to another geosynchronous satellite

9:09 am

The French startup Aldoria has released a short movie taken by its ground telescopes showing a Russian “inspector” satellite maneuvering close to another geosynchronous satellite.

In a recent operation, Aldoria detected a sudden close approach by the Russian Luch Olymp K-2 (Luch-2) to a satellite positioned in geostationary orbit (GEO). This manoeuvre occurred on April 12, around 35,780 km in altitude, highlighting the increasing complexity of space activities. Luch Olymp 2, known for its unusual manoeuvres was predicted, by Aldoria, to closely approach the satellite prior to the observed manoeuvre. The original Luch-1, launched in 2014, was known for similar abnormal behaviour, creating a heightened sense of vigilance within the space community. Luch-2, like its predecessor, has a history of unusual manoeuvring near other satellites in geostationary orbit, which has also generated suspicions regarding its mission.

You can see the video here.

In the past year it appears the entire aerospace industry in Europe has come alive, no longer captured by the European Space Agency’s government-owned commercial arm, Arianespace. Instead, there are companies popping up everywhere, doing the kinds of entrepreneurial work American companies have been known to do since the founding of the country.

The competition for business and the amount of innovation in space should get very brisk in the next few years.

SpaceX now targeting June 6, 2024 for Starship/Superheavy launch

8:58 am

Over the weekend SpaceX announced on X that it has now delayed by one day its targeted date for the fourth orbital test flight of its Starship/Superheavy rocket, from June 5th to June 6th.

No reason was given for the delay, though the company notes on its webpage for the mission that it is still awaiting regulatory approval.

Musk underlined the company’s readiness to launch however with his own tweet on June 2, stating simply that “Starship is ready to fly.”

From the FAA however we still have silence.

Chang’e-6 ascender carrying lunar samples lifts off Moon

8:52 am

main screen. Click for original.

Early today the ascender of China’s Chang’e-6 lunar probe lifted off the surface on the Moon’s far side, carrying the samples it had obtained both by drilling and the use of a robot arm.

The ascender took off at 7:38 a.m. (Beijing Time) from the moon’s far side. A 3,000-newton engine, after working for about six minutes, pushed the ascender to the preset lunar orbit, according to the CNSA.

The Chang’e-6 probe, comprising an orbiter, a lander, an ascender and a returner — like its predecessor Chang’e-5 — was launched on May 3. The lander-ascender combination, separated from the orbiter-returner combination on May 30, touched down at the designated landing area in the South Pole-Aitken (SPA) Basin on June 2.

The spacecraft finished its intelligent and rapid sampling work, and the samples were stowed in a container inside the ascender of the probe as planned, the CNSA said.

At some point, not yet specified, the ascender will dock with the orbiter-returner and transfer the samples to the returner, which after a period in orbit awaiting the right moment will then separate and head back to Earth.

China releases movie taken by Chang’e-6 during its lunar descent

8:45 am

Chang'e-6 landing zone
Chang’e-6’s landing zone is indicated by the
red box, on the edge of Apollo Creater
(indicated by the wavy circle).

China’s state-run press yesterday released a short movie created from images taken by its Chang’e-6 lander during its descent to the lunar surface on the far side of the Moon this past weekend.

I have embedded that footage below. The final five frames however are very puzzling, in that they do not appear to show a smooth descent to a specific spot, but appear to jump about wildly. Moreover, the footage does not appear to show the actual landing itself, but appears to stop while the spacecraft is still above the ground.

It is possible that this footage is simply showing the spacecraft’s software searching for a good landing spot, combined with a decision in China not to release footage of the actual touchdown. It could also be that something has gone wrong, and they are stalling about saying so. This last possibility I think very unlikely, but it must be considered, based on the information available.

NASA confirms June 5th as new launch date for Starliner

8:33 am

NASA yesterday evening confirmed that the agency, ULA, and Boeing are now targeting June 5, 2024 at 10:52 am (Eastern) for the launch of the first manned launch of Boeing’s Starliner capsule carrying two astronauts to ISS for a two week checkout mission.

Technicians and engineers with ULA (United Launch Alliance) worked overnight and on Sunday to assess the ground support equipment at the launch pad that encountered issues during the countdown and scrubbed the June 1 launch attempt. The ULA team identified an issue with a single ground power supply within one of the three redundant chassis that provides power to a subset of computer cards controlling various system functions, including the card responsible for the stable replenishment topping valves for the Centaur upper stage. All three of these chassis are required to enter the terminal phase of the launch countdown to ensure crew safety.

On Sunday, the chassis containing the faulty ground power unit was removed, visually inspected, and replaced with a spare chassis. No signs of physical damage were observed. A full failure analysis of the power unit will be performed to better understand root cause. Meanwhile, ULA has completed functional checkouts of the new chassis and the cards, and all hardware is performing normally.

These kinds of technical issues happen too often on ULA launches. Company engineers always fix them, but it never appears they fix them permanently. Too often on launches they pop up again, causing more scrubs.

The goal should be to fix them so they never pop up again, and your launches can begin to launch reliably, on time. And we know it can be done, because SpaceX has done it.

Chang’e-6’s lander successfully soft lands on far side of the Moon

8:47 pm

Chang'e-6 landing zone
Chang’e-6’s landing zone is indicated by the
red box, on the edge of Apollo Creater
(indicated by the wavy circle).

China today announced that today at 6:23 pm (Eastern) the lander of its Chang’e-6’s lunar orbiter successfully soft landed on far side of the Moon.

Teams will now begin initial checks of the lander’s systems and soon begin collecting samples. The lander will collect up to 2,000 grams of samples, using a scoop to grab surface regolith and a drill for subsurface material. Samples are expected to be sent into lunar orbit within around 48 hours. Chinese space authorities have yet to publish a timeline for the mission and its steps, however.

Once docked to the orbiter, the samples will get transferred to the return spacecraft, which will return to Earth and land in China, in the same manner as was done with its Chang’e-5 sample return mission in 2021. Unlike those earlier samples, which came from the Moon’s near side (where the Apollo and Soviet samples had come from), these new samples will be first obtained from the far side.

Japanese billionaire cancels his “Dear Moon” Starship mission

10:35 am

The Japanese billionaire, Yusaku Maezawa, today announced he has canceled his “Dear Moon” Starship mission that was supposed to take him and a bunch of artists and writers on a fly-by mission to the Moon.

Maezawa suggested the cause of the cancellation was uncertainty over the project development, saying he signed the contract in 2018 based on the assumption the launch would come by the end of 2023. “It’s a developmental project so it is what it is, but it is still uncertain as to when Starship can launch,” Maezawa said. “I can’t plan my future in this situation, and I feel terrible making the crew members wait longer, hence the difficult decision to cancel at this point in time.”

This decision really suggests to me that Maezawa’s whole project was simply a PR stunt. It seems strange to cancel now, when actual test launches of Superheavy/Starship are taking place and showing solid and speedy progress.

No matter. I have no doubt others will show up and buy flights. I also would not be shocked in the slightest if another billionaire shows up to and offers to fly the artists and writers who won seats on Maezawa’s proposed flight.

Boeing Starliner launch scrubbed at T-3:50

10:10 am

UPDATE: The launch is now scheduled for June 5, 2024 at 10:52 am (Eastern).

For reasons that appeared related to the ground system’s of ULA’s Atlas-5 rocket, the first manned launch of Boeing’s Starliner’s capsule was scrubbed today at T-3:50.

It appears they want to try again tomorrow at 12:03 pm (Eastern), assuming ULA can figure out what happened.

The repeated scrubs and delays that have so far prevented this launch are beginning to remind my of my childhood watching the early NASA launch attempts during the Mercury program. Then, they hadn’t done this before, and were being very careful about everything.

Now, it seems that NASA, ULA, and Boeing are acting the same way, and that is probably because they are very nervous about Starliner and don’t want anything to go wrong.

I had intended to embed the live stream, but slept late (it IS the weekend, y’know). Sorry.

Watching the first manned launch of Boeing’s Starliner capsule

9:31 am

NASA has now announced the broadcast schedule for tomorrow’s 12:35 pm (Eastern) launch of Boeing’s Starliner capsule on its first manned mission to ISS.

NASA will provide live coverage of prelaunch and launch activities for the agency’s Boeing Crew Flight Test, which will carry NASA astronauts Butch Wilmore and Suni Williams to and from the International Space Station.

Launch of the ULA (United Launch Alliance) Atlas V rocket and Boeing Starliner spacecraft is targeted for 12:25 p.m. EDT Saturday, June 1, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Starliner will dock to the forward-facing port of the station’s Harmony module at approximately 1:50 p.m., Sunday, June 2.

The live stream will begin on NASA TV at 8:15 am (Eastern). I will embed that live stream here tomorrow. As this start time is more than four hours before launch, expect there to be endless NASA propaganda for most of that time. My advice is to tune in at around noon.

Let us all pray that all goes well on this flight. Boeing’s recent track record has generally be horrible. We can only hope its engineers have gotten all of the kinks out of this capsule.

SpaceX completes second Starship/Superheavy dress rehearsal countdown; no launch licence yet from FAA

9:22 am

Though SpaceX has now successfully completed a second Starship/Superheavy dress rehearsal countdown in preparation for its targeted June 5, 2024 launch date, the FAA has still not issued the company a launch licence.

The report at the link is very optimistic about the FAA issuing the license, though there as yet no indication that it will do so.

There are two ways to return to flight. Previously, all Starship mishaps were closed using Path One, which means the FAA accepts a SpaceX-led mishap investigation report, where the operator identifies corrective actions for the vehicle and implements them on future flights.

For this flight, SpaceX chose Path Two, which involves an FAA public safety determination. In this process, the FAA makes a safety determination based on all available information to see if the previous flight involved safety-critical system failures. If successful, a return to flight can be conducted even without the closure of the mishap report.

In a statement to [NASASpaceFlight], the FAA reported: “After a comprehensive review, the FAA determined no public safety issues were involved in the anomaly that occurred during the SpaceX Starship OFT-3 launch on March 14. This public safety determination means the Starship vehicle may return to flight operations while the overall investigation remains open, provided all other license requirements are met.

SpaceX has not yet received FAA license authorization for the next Starship launch.”

We shall see. I suspect the people at the FAA want to issue that license. I also suspect that the White House is demanding the full investigation be completed beforehand.

Engineers lose contact with Japan’s Akatsuki Venus orbiter

9:11 am

According to a terse announcement by Japan’s space agency JAXA on May 29, 2024, engineers from its Institute of Space and Astronautical Science (ISAS) have lost contact with Japan’s Akatsuki Venus orbiter.

ISAS has lost contact with Akatsuki after an operation in late April due to an extended period of low attitude stability control mode, and is currently making efforts to reestablish communication with the spacecraft.

Akatsuki has had a spotty and complex life. It was launched in 2010, but failed to enter Venus orbit as planned in two attempts in 2010 and 2011 because of a failure in its main engine. Engineers then improvised and — after orbiting the Sun for several years — were able to get it into Venus orbit in 2015 using only its attitude thrusters. Its primary mission ended in 2018, but it continued to study Venus’ atmosphere since.

Assuming Akatsuki is not recovered, as of now there are no operating orbiters at Venus. A mission by the private company Rocket Lab is expected to launch before the end of this year, followed by an orbiter from India in 2026. A NASA mission meanwhile is in limbo and will likely never fly, due to budget decisions at the agency, which took its funding and gave it to the troubled Mars Sample Return mission.

Starlab space station signs cargo contract with French startup

8:42 am

The French startup, The Exploration Company, on May 28, 2024 signed a contract with the consortium of American and European companies building the Starlab space station to fly three cargo missions using its proposed reusable Nyx unmanned freighter.

The Exploration Company is developing its reusable Nyx spacecraft, which will initially ferry cargo to and from low Earth orbit. The company also plans to offer versions of the spacecraft for crewed spaceflight in low Earth orbit and missions to the surface of the Moon. Earlier this month, The Exploration Company was awarded an initial €25 million European Space Agency (ESA) contract to perform a demonstration mission to ferry cargo to and from the International Space Station (ISS) as part of the agency’s LEO Cargo Return Services initiative.

Starlab, first proposed by the American company Voyager Space, has a development contract with NASA. Its partnership includes Lockheed Martin, Northrop Grumman, Airbus, Mitsubishi, and MDA Space. It has also signed a similar deal with India’s space agency ISRO to use its Gaganyaan manned capsule, as well as another deal with SpaceX’s Starship.

Chinese pseudo-company launches five satelites

8:29 am

The Chinese pseudo-company Galactic Energy today successfully launched five satelites, its Ceres-1 rocket lifting off from the Jiuquan spaceport in northwest China.

This was Galactic Energy’s second launch in the past two days. China’s state-run press however made no mention of the company in its report, a lack that is now routine. Apparently the Chinese government recognizes these pseudo-companies might eventually pose a threat to its power, and doesn’t wish to give them any extra publicity.

The report also made no mention of where the rocket’s solid-fueled lower stages crashed inside China.

The leaders in the 2024 launch race:

57 SpaceX
26 China

American private enterprise still leads the world combined in successful launches, 65 to 40, while SpaceX by itself leads the entire world, including other American companies, 57 to 48.

A second Indian rocket startup completes suborbital launch

9:34 am

Agnikul's first suborbital test launch
Yesterday’s launch. Click for original image.

The Indian rocket startup Agnikul Cosmos yesterday successfully completed a suborbital test launch, flying a prototype stage using a single 3-D printed engine that lifted off from India’s Sriharikota spaceport on its eastern coast. From the first link:

All the mission objectives of this controlled vertical ascent flight were met and performance was nominal. The vehicle was completely designed in-house and was powered by the world’s first single piece 3d printed engine and also happens to be India’s first flight with a semi cryo engine.

The company claims this launch took place at its privately built launchpad, but that pad is located south of ISRO’s Sriharikota spaceport. Did it shift the launch back to Sriharikota, or are the reports incorrect? It is not clear.

Another Indian rocket startup, Skyroot, completed a similar suborbital test launch in November 2022, and has since followed this up with static fire tests of the upper stage of its Vikram-1 rocket.

Both companies hope to complete their first orbital launches before the end of 2025.

Launches by China and Russia

9:16 am

Earlier today both China and Russia successfully completed launches.

First, China launched a Chinese-built Pakistani communications satellite into orbit, its Long March 3B rocket lifting off from its Xichang spaceport from the southwest of China.

No real information was released about the satellite, or the fate of the rocket’s lower stages and four strap-on boosters, all of which use toxic hypergolic fuels and certainly crashed somewhere in China.

Next, Russia successfully launched a new Progress cargo ship to ISS, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan. The freighter will dock with ISS tomorrow. I have embedded video of the launch below, cued to T-30 seconds.

The rocket’s flight path took it over Kazakstan, Russia, and China, with drop zones for the lower stages in the first two. No word on whether the lower stages and four strap-on boosters crashed near habitable areas.

The leaders in the 2024 launch race:

57 SpaceX
25 China
8 Russia
6 Rocket Lab

American private enterprise still leads the world combined in successful launches, 65 to 39, while SpaceX by itself leads the entire world, including other American companies, 57 to 47.

Chang’e-6 to attempt landing on Moon’s far side on June 1st

9:42 am

Chang'e-6 landing zone

After spending almost a month in lunar orbit, the lander on China’s Chang’e-6 sample return mission will attempt a soft touchdown on Moon’s far side on June 1, 2024 at 8:00 pm (Eastern).

If successful, the lander will go through initial checks and setup. It will then begin drilling and scooping up materials from the surface. These samples, expected to weigh up to 2,000 grams, will be loaded into an ascent vehicle. The ascender will then launch the precious cargo back into lunar orbit for rendezvous and docking with the orbiter. Surface operations will last about 48 hours.

The map to the right indicates the landing zone by the red box, on the southern edge of Apollo Crater, indicated by the wavy white circle. The black circle marks the perimeter of South Aitken Basin, the largest impact basin on the Moon.

Once the ascender docks with the orbiter, the sample will be transferred into the sample return capsule, which will bring that sample back to Earth in late June.

Botswana approves Starlink

9:32 am

After first denying SpaceX the right to sell Starlink in Botswana in February, government officials have now done a sudden about-face and approved Starlink.

During a business summit in the United States earlier in May, President Mokgweetsi Masisi met with Ben MacWilliams, the Director of Starlink’s Global Licensing and Activation, who expressed interest in obtaining a license to operate in Botswana. Following this meeting, President Masisi decided to approve Starlink’s licensing and instructed the regulator to expedite the application process within two weeks.

I could speculate on what caused the president to change his mind after this meeting, but I’ll leave that to my readers.

SLIM goes dark

9:14 am

SLIM's landing zone
Map showing SLIM landing zone on the Moon.
Click for interactive map.

The Japanese lunar lander SLIM has failed to respond to ground commands sent soon after dawn, ending the lander’s fourth night on the Moon.

SLIM was never expected to survive the harsh conditions of even a single 14-day-long lunar night after landing on the Moon in January 2024. Its primary mission had been to test precision autonomous landings, which it did successfully (though it landed on its side when one nozzle fell off just before touchdown). Yet, it then survived three lunar nights, resuming communications at dawn.

Its failure now is therefore no surprise, and actually marks a magnificent engineering success. The spacecraft’s hardware was proven robust enough to survive the very cold temperatures during lunar night, and suggests that future Japanese lunar landers using SLIM designs will function as well.

Avio completes static fire test of the upper stage of its grounded Vega-C rocket

9:03 am

The Italian company Avio yesterday completed a full static fire test of the solid-fueled upper stage of its grounded Vega-C rocket, proving that the second redesign of its nozzle now works.

The initial post-test review indicates that the new nozzle assembly performed as expected throughout the scheduled 94 seconds burning time of the test, simulating a nominal in-flight performance.

The Zefiro-40 is a 7.6 m tall rocket motor, loaded with over 36 tonnes of solid propellant. For this test the motor was installed on its horizontal test bench. Zefiro-40 is developed and manufactured by Avio in their Colleferro factory near Rome, Italy.

A second firing-test will be conducted after the summer to confirm the data collected today. Avio engineers will review the data from the first test to prepare for a second test in October that will then qualify the second stage Zefiro-40 solid rocket motor for a return-to-flight by end 2024 from Europe’s Spaceport in French Guiana.

The nozzle — originally built in the Ukraine — had failed during a launch in December 2022. Then Avio’s first redesign failed in a ground test in July 2023.

With this launch, the Vega-C is poised to resume operations by the end of the year. Those operations will be different however in one major respect. While previously the rocket was built by Avio but owned and controlled by the European Space Agency’s commercial arm, Arianespace, its ownership has been transferred back to Avio. Arianespace is now merely a “launch service provider” according to the press release. I suspect this means that Arianespace handles the launch in French Guiana, something that will also soon be taken from it because control of that spaceport is also being returned to the French space agency CNES.

China launches four satellites from sea platform

8:45 am

China's spaceports

The Chinese pseudo-company Galactic Energy today launched four satellites, its Ceres-1 rocket lifting off from its sea platform stationed off the coast of Shandong province, as shown on the map to the right.

As is usual now for China’s state-run press, the news report made no mention of the company, though unlike previous reports it did mention that the rocket was “commercial.” Since it does nothing without the full permission of the Chinese government, however, this is not a real independent company, with full ownership of its rocket. At any time the communists who run China can grab it for their own uses.

The leaders in the 2024 launch race:

57 SpaceX
24 China
7 Russia
6 Rocket Lab

American private enterprise still leads the world combined in successful launches, 65 to 37, while SpaceX by itself leads the entire world, including other American companies, 57 to 45.
