SpaceX completes two Starlink launches hours apart

9:49 am

SpaceX last night completed two Starlink launches hours apart from opposite coasts. First its Falcon 9 rocket took 23 Starlink satellites into orbit, lifting off from Cape Canaveral. The first stage completed its 16th flight, landing on a drone ship in the Atlantic.

Then, a Falcon 9 rocket lifted off from Vandenberg carried 20 Starlink satellites into orbit, its first stage completing its 21st flight (tying the record), landing safely on a drone ship in the Pacific.

The leaders in the 2024 launch race:

62 SpaceX
27 China
8 Russia
7 Rocket Lab

American private enterprise now leads the world combined in successful launches, 72 to 41, while SpaceX by itself leads the entire world, including other American companies, 62 to 51.

Close-up of rocks on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 6, 2024 by Curiosity’s Mars Hand Lens Imager (MAHLI), located at the end of the rover’s robot arm and designed to get close-up high resolution images of the ground that the arm is exploring.

The picture above, taken just after the one to the right and cropped, reduced, sharpened, and annotated to post here, shows the robot arm shortly after it has rotated upward after placing MAHLI right up against the ground. Note the tread marks. The science team apparently chose these target rocks because they were likely ground somewhat as the rover rolled over them, breaking the rocks to expose new faces.

According to the scientists, the camera was about two to three inches away from these rocks when it snapped the picture, with the scale about 16 to 25 microns per pixel. Since a micron is one millionth of a meter, this picture is showing us some very small details within a much larger rock.

I post this because I have rarely seen such colorful and crystal-like surface features from Curiosity.

Chinese pseudo-company raises $207 million

9:53 am

The Chinese pseudo-company Space Pioneer announced yesterday that it has raised an additional $207 million from Chinese investment sources during its most recent funding round, bringing the total amount it has raised to $552 million.

Space Pioneer—full name Beijing Tianbing Technology Co., Ltd—announced the funding worth more than 1.5 billion yuan ($207 million) June 6. At least 15 investors participated in the funding, including a mix of private equity and state-linked investment vehicles.

These include state-linked Wuxi Chuangfa, CCTV Fund, CITIC Securities Investment, Hefei Ruicheng and SDIC Taikang, and private equity and investment firms Bohua Capital Management, Guoyu Gaohua, Deyue Investment and more.

The company is developing its Tianlong-3 reusable rocket, essentially a copy of SpaceX’s Falcon 9. It already has completed one launch of its Tianlong-2 expendable rocket, using government engines.

Iran to build coastal spaceport

9:47 am

Iran's spaceports

According to Issa Zarepour, Iran’s minister of communications and information technology, Iran is now planning a new spaceport on its southern coast near the city of Chabahar.

“[The process of construction of] the first phase of the port is being completed thanks to round-the-clock endeavor,” he said. He noted that the process had so far witnessed as much as “56-percent physical progress.”

“The facility would be inaugurated by the Ten-Day Dawn ceremonies,” the minister said. He was referring to the 10-day-long annual celebrations that mark the historic run-up to the victory of the country’s Islamic Revolution in 1979. The celebrations will start in late January next year.

The spaceport is expected to host its first launch by next March, Zarepour added.

The map shows Chabahar’s location. It also shows Iran’s present spaceport in Semnan, where it has previously launched all its rockets.

ESA signs deal with Vast to use its Haven-1 space station

2:51 pm

Vast Haven-1 station inside Falcon-9 fairing

The European Space Agency (ESA) and the commercial space station startup Vast today signed an agreement that sets the initial terms for ESA to use Vast’s first space station, Haven-1, as well as any space stations to follow.

The agreement outlines the parties’ intention to foster human spaceflight, science, technology and commercialisation development and explore collaboration in low Earth orbit destinations other than the International Space Station. The collaboration will initially focus on exploring opportunities for access to space for Europe through the Vast Space Stations. These could include:

  • Access to the Vast Space Stations for ESA and its Member States, for astronaut missions and research activities as well as commercial business development.
  • Supporting European industry to supply subsystems and equipment for future Vast Space Stations.
  • Vast making use of future qualified European LEO cargo and/or crew transportation services, at market rates and commercially viable terms and conditions, also as a means for offsetting future ESA Astronaut Missions.
  • Vast and ESA jointly supporting European industry in getting certified for docking to future Vast Space Stations.

This deal is actually a very big deal, as Vast’s Haven-1 space station is the only one under construction that does not have a deal with NASA. It is being financed privately and will at first simply be a one module habitat set to launch as early as August 2025 on a Falcon 9 rocket, with the first 30-day 4-person manned mission to follow almost immediately on a Dragon capsule. Vast’s work is closely linked with SpaceX, as its station also has a deal to use Starlink for communications.

The plan is to add more modules in the coming years to build up to a full station.

This deal not only indicates that this independent station is going to give the NASA-supported stations some real competition, it indicates that Europe is committed to doing the same. Now that Europe has abandoned the government-owned and international cooperation model it has used for decades with decidedly mixed results and switched to the capitalism model, where it is merely a customer buying things from a competing private sector, it is doing so full speed ahead, without any hesitation.

The independence of this station also frees it and its customers from the heavy rules that NASA routinely imposes on anyone who deals with it. This aspect gives Vast a competitive advantage that many will clearly wish to take advantage of.

This deal is therefore a challenge that better be recognized by NASA and the other commercial stations. If they don’t react properly they could find themselves left in the dust completely.

Boeing’s Starliner successfully docks with ISS

10:57 am

Despite several minor helium leaks and the failure of 6 of its 28 small attitude thrusters (four of which were reactivated during an improvised hot fire test during rendezvous operations), Boeing’s Starliner has successfully docked with ISS today.

Though now safely arrived at ISS, the hatch has not yet opened. The spacecraft carries NASA astronauts Butch Wilmore and Suni Williams, and will now spend about a week at the space station checking out its systems before undocking and returning to Earth.

All told, this docking is a success, though the various thruster issues are a concern that must be addressed by Boeing, especially because there were thruster issues as well during the previous unmanned demo flight.

Telescope removed from Mauna Kea on Big Island as local Hawaiian council rejects new telescopes on Haleakala on Maui

8:09 am

Even as a local Hawaiian authority on the Big Island has completed the removal of the first of three telescopes on the top of Mauna Kea, a local council on the island of Maui have voted 9-0 to oppose an Air Force project to build new telescopes on top of Haleakala.

The proposed new facility is called AMOS STAR, which is an acronym for Air Force Maui Optical and Supercomputing Site Small Telescope Advanced Research. It would feature six telescopes enclosed in ground-mounted domes and one rooftop-mounted domed telescope.

The county’s resolution urged the military to heed community calls to cease their development efforts. It urged the National Park Service, Federal Aviation Administration and the Hawaii Department of Land and Natural Resources to deny the project permits.

At this time it appears that Hawaiians desended from the original indigenous population are opposed to all western technology, even as they rely on it. These new telescopes are proposed by the Air Force because it needs better capilities to track the tens of thousands of new satellites being launched by numerous companies and governments. This information will help prevent collisions in space.

As for their claims that these peaks are “considered wao akua, or ‘realm of the gods,’ and [places] of deep spirituality for Native Hawaiians to engage in some of these traditional practices,” as stated in the council’s resolution, I have some doubts. For almost three-quarters of a century such religious concerns and objections were never mentioned by anyone. If they existed indigenous Hawaiians appeared to have no problem “engaging in traditional practices” right next to telescopes. Only when some activists appeared in the past decade, looking to insert themselves in the process (thus obtaining positions of power and money) did the peaks become so important religiously.

Lunar samples transferred to Chang’e-6 return vehicle

7:54 am

According to China’s state-run press, the ascent vehicle has docked with the Chang’e-6 orbiter and successfully transferred its lunar samples to the return spacecraft that will bring those samples back to Earth.

The ascender of China’s Chang’e-6 probe successfully rendezvoused and docked with the probe’s orbiter-returner combination in lunar orbit at 2:48 p.m. (Beijing Time) on Thursday, the China National Space Administration (CNSA) announced.

The container carrying the world’s first samples from the far side of the moon had been transferred from the ascender to the returner safely by 3:24 p.m., the CNSA said.

That return is scheduled for later this month. In the meantime the orbiter will adjust its position in preparation for sending the return capsule back.

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.

Hubble once again in safe mode due to gyro problem

10:23 am

On May 24, 2024 the Hubble Space Telescope once again paused its science operations and entered in safe mode, apparently due to gyroscope problem.

The telescope automatically entered safe mode when one of its three gyroscopes gave faulty telemetry readings. Hubble’s gyros measure the telescope’s slew rates and are part of the system that determines and controls precisely the direction the telescope is pointed. NASA will provide more information early the first week of June.

It is not clear if this is the same gyroscope that caused the last two safe mode events.

With each such event the telescope gets closer and closer to having only two gyroscopes. At that point it will shift to one-gyro mode, using only one and holding the second in reserve. From then on it will no longer be able to take perfectly sharp pictures. Science will still be possible, but not like before.

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.

The recovered diary of Columbia’s Israeli astronaut now on loan to Israel’s national library

9:50 am

One page from Ilon Ramon's space diary
One page from Ilon Ramon’s space diary

According to a May 29, 2024 announcement by the National Libary of Israel, the recovered diary of astronaut Ilan Ramon — who died when the space shuttle Columba broke up on its return to Earth — has now been transferred from the Israel Museum to the National Library of Israel so that it can finally be put on display.

The diary, a personal and national treasure, should have disintegrated along with the shuttle and its crew, but a few weeks after the disaster, to the surprise of the search party, someone found the remains of the diary on a muddy patch of land in Texas.

How is it possible that it survived? It withstood the explosion, and then a journey of several kilometers till it hit the earth. No one knows for sure, but leading researchers in the field believe that due to the light weight of the pages, the diary didn’t fall directly to the ground but probably glided slowly downwards, carried on wind currents that eventually allowed for a soft landing. Most of the damage to its pages probably only happened after it reached the ground, resulting from the humid conditions in the marshy area where it landed.

Since then the Israel Museum has been carefully documenting its contents, which included daily accounts by Ramon of his experience in space. One example:

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.
