China launches two GPS-type satellites

4:06 pm

China today successfully launched two more BeiDou satellites for its GPS-type navigation constellation, its Long March 3B rocket lifting off from its Xichang spaceport in the southwest of China.

No word on where the strap-on boosters and lower stages crashed in China, all using toxic hypergolic fuels.

The leaders in the 2024 launch race:

92 SpaceX
39 China
11 Russia
10 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 107 to 61, while SpaceX by itself still leads the entire world, including American companies, 92 to 76.

The Democrats: 28% think it would be a good thing if Trump were killed

2:05 pm

Poll proving how murderous the Democrats have become
Click for original image.

The Democrats and their supporters might claim they stand for democracy and freedom and fair elections, but their own words prove this endlessly to be a lie. In a new poll of a 1,000 registered voters, 28% of the Democrats thought the country would be better off if Trump were assassinated.

Sadly, as shown by the graph to the right, 7% of the Republicans polled also thought killing Trump would a good thing.

The difference between the two numbers however illustrates the stark difference between the two parties, and helps explain why there have been two assassination attempts on Trump and none on the Democratic Party candidates. Republicans mostly support democracy and free and fair elections. A large percentage of Democrats no longer do.

Furthermore, Democrats also appear to be so filled with their hatred of Trump and any opposition that they can no longer think rationally about anything. The poll also found that 70% believed it likely or somewhat likely that the second assassination attempt was faked by Trump and his campaign.

All of this hatred among grassroots Democrats is worsened because the leadership of the Democratic Party keeps feeding it. » Read more

Webb takes an infrared look at a galaxy looked at by Hubble

12:21 pm

Comparing Hubble with Webb
For original images go here and here.

Cool image time! The bottom picture on the right, cropped to post here, is a just released false color infrared image of the galaxy Arp 107, taken by the Webb Space Telescope. The picture at the top is a previously released optical image taken by the Hubble Space Telescope and featured as a cool image back in September 2023. The Hubble image was taken as part of a survey project to photograph the entire Arp catalog of 338 “peculiar galaxies,” put together by astronomer Halton Arp in 1966. In this case Arp 107 is peculiar because it is actually two galaxies in the process of merging. It is also peculiar because the galaxy on the left has an active galactic nuclei (AGN), where a supermassive black hole is sucking up material and thus emitting a lot of energy.

The Webb infrared image was taken to supplement that optical image. The blue spiral arms indicate dust and star-forming regions. The bright orange object in the center of the galaxy is that AGN, clearly defined by Webb’s infrared camera.

When I posted the Hubble image in 2023, I noted that “if you ignore the blue whorls of the left galaxy, the two bright cores of these merging galaxies are about the same size.” In the Webb image the two cores still appear about the same size, but in the infrared they produce emissions in decidedly different wavelengths, as shown by the different false colors of orange and blue. The core of the galaxy on the right is dust filled and forming stars, while the core of the left galaxy appears to have less dust with all of its emissions resulting from the energy produced by the material being pulled into the supermassive black hole.

The universe is very active and changing, but to understand that process we humans have to look at everything across the entire electromagnetic spectrum, not just in the optical wavelengths our eyes see.

Newly discovered potentially dangerous asteroid found to be a contact binary

11:38 am

Radar images of asteroid 2024ON
Click for original image.

Radar images taken during the close fly of a newly discovered potentially dangerous asteroid has revealed that it is a contact binary, formed by two objects stuck together to produce a single asteroid with a peanutlike shape.

Discovered by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) on Mauna Loa in Hawaii on July 27, the near-Earth asteroid’s shape resembles that of a peanut. Like the asteroid 2024 JV33 that made close approach with Earth a month earlier, 2024 ON is likely a contact binary, with two rounded lobes separated by a pronounced neck, one lobe about 50% larger than the other. The radar images determined that it is about 755 feet (350 meters) long. Features larger than 12.3 feet (3.75 meters) across can be seen on the surface. Bright radar spots on the asteroid’s surface likely indicate large boulders. The images show about 90% of one rotation over the course of about six hours.

The radar images were taken one day before that close approach of 620,000 miles on September 17, 2024, and once again show that a large number of near-Earth asteroids, as much as 14%, are contact binaries. The data also helped better refine 2024ON’s orbit around the Sun, which show that though the asteroid has the potential to hit the Earth, its path will not do so for the foreseeable future.

Phobos rising and Earth setting as captured together by Curiosity

10:56 am

Phobos and Earth in the Martian sky
Click for original image.

Cool image time! The picture to the right, enhanced and reduced to post here, was taken by the high resolution camera on the Mars rover Curiosity on September 5, 2024.

What makes this picture unique are the two tiny spots near the upper right. For the first time, Curiosity’s camera was able to capture both the Earth and the Martian moon Phobos in the same picture, when they were also very close to each other in the sky. From the caption:

NASA’s Curiosity Mars rover used its Mast Camera, or Mastcam, to capture this view of Earth setting while Phobos, one of Mars’ two moons, is rising. It’s the first time an image of the two celestial bodies have been captured together from the surface of Mars.

The image is a composite of five short exposures and 12 long exposures all taken on Sept. 5, 2024, the 4,295th Martian day, or sol, of Curiosity’s mission. An inset in the image [found here] shows Phobos on the left and Earth on the right. From the rover’s perspective, the inset area would be about half the width of a thumb held at arm’s length.

The dark shape in the lower left is one of the buttes that surround Curiosity as it has been climbing up Mount Sharp and traversing inside the Gediz Vallis slot canyon.

The inset provides a close-up of the two objects, but the resolution is poor. To me, it is much more interesting to look at the picture to the right, that shows what these two objects actually looked like in the sky of Mars.

FCC commissioner slams FCC for its partisan hostility to SpaceX

10:27 am

The FCC proves its partisan hostility to SpaceX
The FCC proves its partisan hostility to SpaceX

Even as the FAA has increasingly appeared to be harassing SpaceX with red tape, FCC commissioner Brendan Carr this week slammed his own agency for what appears to be clearly partisan hostility to SpaceX in its recent decisions and public statements.

Carr noted how only last year the FCC had canceled an almost $900 million grant that it had previously awarded to SpaceX for providing rural communities internet access. When it did so, the FCC claimed that the company had failed to “demonstrate that it could deliver the promised service.”

That claim of course was absurd on its face, considering that Starlink was the only available commercial system that was actually doing this, directly to individual rural customers.

Carr noted however that this absurd FCC decision was made even more ridiculous this week by the FCC’s chairperson, Jessica Rosenworcel, who accused SpaceX of being a “monopoly” because of its success in launching Starlink satellites and providing this service ahead of everyone else.

Sierra Space successfully tests equipment for extracting oxygen from the lunar soil

9:57 am

In a press release this week Sierra Space revealed that it has successfully tested an extraction system that can gather up the abrasive lunar regolith and then heat it to high temperatures in order to extract and use the oxygen contained in that soil.

Temperatures in which the Sierra Space Carbothermal Oxygen Production Reactor were tested ranged from minus 45 degrees Celsius to 1,800 degrees Celsius. In addition to the challenges of functioning from sub-zero to hotter-than-lava temperatures, the hardware was required to move the simulated lunar regolith – a very abrasive and jagged material because it does not have the weathering processes found on Earth – through its system. The potentially damaging particles were handled effectively by the hardware and gasses were successfully sealed inside the reactor, thanks to Sierra Space’s use of a patent-pending valve design that previously demonstrated functionality to greater than 10,000 cycles.

The tests confirmed that Sierra Space’s system can successfully handle regolith that would be delivered from a lunar rover or robotic arm and automatically bring it into the reaction chamber, perform the carbothermal reduction reaction process to extract the oxygen from the minerals in the regolith, and remove the processed regolith from the system so the operation can be repeated.

This research is similar to the extraction system the Chinese are developing, though it appears Sierra’s system appears considerably closer to a finished product, as it is already being tested.

Eutelsat awards multi-launch contract with Mitsubishi

9:42 am

The French communications satellite company Eutelsat has awarded the Japanese company Mitsubishi a multi-contract using its H3 rocket.

The company did not reveal the contract amount or the number of launches involved. The first launches however will begin in 2027, with company officials explaining why they signed the deal.

The operator already has launches mostly covered for deploying its next-generation OneWeb broadband satellites in low Earth orbit (LEO), CEO Eva Berneke recently told SpaceNews. However, these launches include 3D printing specialist Relativity Space’s Terran R vehicle and Europe’s next-generation launcher Ariane 6, which have both already experienced development delays.

Ariane 6 is also part of the multi-billion-dollar launch campaign Amazon plans to kick off this year for its LEO constellation. “Given that Amazon has acquired Ariane 6 rockets, if we wanted to use it in, say, 2027, are we going to fit into their launch manifest or not?” Berneke told SpaceNews in the interview.

There are two interesting aspects to this deal. First, Eutelsat decided it needed to diversify its launch providers. The status of Relativity’s Terran-R rocket remains uncertain, and if it goes under Eutelsat would be left with just Ariane-6, which has its own issues and might not be able to meet the demand.

Second, Eutelsat clearly decided it did not want to give this business to SpaceX. I guarantee SpaceX’s price was less than Mitsubishi’s since the H3 is entirely expendable and very expensive, developed by Mitsubishi primiarly for the Japanese government (which paid the bills) and not as a player in the international launch market. Eutelsat made this choice for probably good and bad reasons. The good reason: All satellite companies need to encourage the success of as many launch providers as possible, to increase its options and competion. Giving business to Mistubishi serves that purpose.

The bad reason? Among many in Europe and elsewhere there is a childish resentment of SpaceX, simply because. No one will say so publicly, and if asked everyone will deny it, but the evidence clearly suggests that this silly emotional factor exists.

Indian government approves major space projects, including new rocket, missions to the moon, space station, Venus

3:54 pm

The cabinet of Modi government in India today approved a whole range of major space projects for the next decade, including a sample return mission to the moon, the building of the first module of that country’s space station, an orbiter to Venus, and the development of a new more powerful but reusable rocket.

The lunar sample return mission, dubbed Chandrayaan-4, is targeting a launch about three years from now, and will be shaped to provide information leading to a manned lunar mission by 2040.

The cabinet also approved the development of the first module of its proposed Bharatiya Antariksh Station (BAS), targeting a 2028 launch date with the full station completed by 2035. This approval also included a plan for manned and unmanned missions leading up to the launch of that first module.

Under the programme eight missions are envisaged — four under the ongoing Gaganyaan programme by 2026, and development of BAS-1, and another four missions for demonstration and validation of various technologies by December 2028.

The Venus Orbiter is now targeting a 2028 launch.

The new launch rocket, dubbed the Next Generation Launch Vehicle (NGLV) will aim for reusability and be 1.5 times more powerful than the India’s presently most powerful rocket, the Launch Vehicle Mark-3 (LVM-3). The program to develop this new rocket however appears overally long (8 years) with relatively little flight testing (3 flights).

Overall, this government space program will likely energize India’s new commercial aerospace industry, as the Modi government is also attempting to shift as much of this work to private companies, rather than have its space agency ISRO do the work.

Pushback: Pastor who was arrested in Seattle for reading the Bible aloud wins in court

2:49 pm

Are Americans finally waking up and emulating their country's founders?

Fight! Fight! Fight!: In 2022 Pastor Matthew Meinecke was arrested two different times by the Seattle police when he attended pro-abortion rallies and simply stood in the crowd and read the Bible aloud. What was worse was that when he was attacked by the pro-abortion protesters the police arrested him, not the attackers.

The conflict came about because Pastor Meinecke went to a Seattle pro-abortion rally to read the Bible aloud, hold up a sign and hand out literature. He was censored and arrested on two separate occasions for simply reading the Bible to others because his Gospel-oriented message triggered hostile reactions from activists.

Despite his evangelistic and peaceful intent, some individuals in the crowd, including Antifa members, did not receive the message well. They took Meinecke’s Bible away from him, ripped out pages, knocked Meinecke down and took one of his shoes. When Seattle police finally arrived at the scene, they did not offer any aid to Meinecke. Instead, they ordered Meinecke to leave and go to a space where he could no longer convey his message, and then arrested him when he declined to do so.

The same thing happened two days later at public park during a queer “PrideFest.”

Axiom in trouble?

10:42 am

Axiom's space station assembly sequence
The assembly sequence for Axiom’s space station while attached to ISS.
Click for original image.

A long article yesterday in Forbes described serious financial issues with the space station startup Axiom, problems so severe the company is laying off workers and has trouble meeting its payroll.

The problems have been accentuated by hiring too many people and the delays in building its modules for attachment to ISS.

The lack of fresh capital has exacerbated long-standing financial challenges that have grown alongside Axiom’s payroll, which earlier this year was nearly 1,000 employees. Sources familiar with the company’s operations told Forbes that cofounder and CEO Michael Suffredini, who spent 30 years at NASA, ran Axiom like a big government program instead of the resource-constrained startup it really was. His mandate to staff up to 800 workers by the end of 2022 led to mass hiring so detached from product development needs that new engineers often found themselves with nothing to do, these people said.

When Axiom was founded in 2016, it promised investors the first station module would be aloft in 2020.

That first module is presently not expected to launch until 2026, six years late. Its main structure is being built by Thales-Alenia in Europe, and work there has been much slower than expected, possibly because Axiom has been slow in providing the expected capital.

The article also describes in detail the financial loss Axiom has experienced in its manned private flights to ISS, where it hires SpaceX to provide the rocket and capsule. The costs have been higher than expected, made worse by requirements and charges imposed on it by NASA. As a result the company lost money on the first three flights, and expects the fourth this year to only break-even.

Whether Axiom will survive, based on this article, is very questionable. We will just have to wait and see however. All other indications suggest it is in a stronger position than at least one other commercial station, Blue Origin-led Orbital Reef, and matches well with Voyager Space’s Starlab. These of the three stations being built with NASA’s financial help.

The one station that might beat them all however remains the entirely private Vast Haven-1 station. It has taken no government money and yet expects to launch its first small module before any of the former stations, in the second half of 2026. and immediatley fly astronauts to it for a 30-day mission.

Musk: We will sue the FAA for “regulatory overreach” and “improper, politically-motivated behavior”

9:38 am

In a series of tweets yesterday Elon Musk announced that SpaceX is going to sue the FAA for its recent actions that have delayed development of Starship/Superheavy and have also fined the company for what appear to be petty reasons.

In the second case, the FAA threatened to fine SpaceX $633K because it had not gotten some minor approvals prior to successfully completing two launches safely. The agency gave SpaceX 30 days to respond.

Musk responded bluntly in a tweet, stating that “SpaceX will be filing suit against the FAA for regulatory overreach.” In a second tweet immediately thereafter Musk added that that the fines were “More lawfare.”

In a third tweet he stated unequivocally, “I am highly confident that discovery will show improper, politically-motivated behavior by the FAA.”

As noted in the first link above, the agency took no action against SpaceX for more than a year after those two launches, only issuing the threat to fine the company now, just before the election, and just after the company had publicly criticized the agency for its delays in issuing a launch license for the fifth Starship/Superheavy test flight. I suspect Musk has some good information of solid evidence that some officials either in the FAA or at the White House instigated this action for political reasons. An honest appraisal of the FAA’s actions sure suggests it.

NASA awards Intuitive Machines $4.8 billion contract to build Moon communication satellite constellation

9:17 am

NASA yesterday awarded Intuitive Machines a contract worth as much as $4.8 billion to build the communication relay infrastructure necessary to support bases and research on the Moon.

This Subcategory 2.2 GEO to Cislunar Relay Services is a new firm-fixed-price, multiple award, indefinite-delivery/indefinite-quantity task order contract. The contract has a base period of five years with an additional 5-year option period, with a maximum potential value of $4.82 billion. The base ordering period begins Tuesday, Oct. 1, 2024, through Sept. 30, 2029, with the option period potentially extending the contract through Sept. 30, 2034.

Lunar relays will play an essential role in NASA’s Artemis campaign to establish a long-term presence on the Moon. These relays will provide vital communication and navigation services for the exploration and scientific study of the Moon’s South Pole region. Without the extended coverage offered by lunar relays, landing opportunities at the Moon’s South Pole will be significantly limited due to the lack of direct communication between potential landing sites and ground stations on Earth.

According to the company’s own press release, this relay system will include a “lunar satellite constellation,” though the number of satellites was not revealed. The system will provide not just communications but will include GPS-type location data for ground operations.

SpaceX launches two more Galileo GPS-type satellites for Europe

12:43 am

SpaceX this afternoon successfully launched two Galileo GPS-type satellites for Europe, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its 22nd flight, landing on a drone ship in the Atlantic. The fairings flew their for their 3rd and 8th times respectively. The launch was the second launch by SpaceX for Europe’s Galileo constellation. The European Commission was forced to award this multi-launch contract to SpaceX because Europe’s Ariane-6 rocket was four years behind schedule and not available when needed.

The leaders in the 2024 launch race:

92 SpaceX
38 China
11 Russia
10 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 107 to 60, while SpaceX by itself still leads the entire world, including American companies, 92 to 75.

Some new “What the heck?” geology on Mars

1:12 pm

What the heck is going on here?
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on April 21, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

My first reaction on seeing this picture was to scratch my head? What am I looking at? Are those fluted dark features going downhill to the south, or uphill to the north? What are they? Are they slope streaks? Avalanches? How do they relate to the flat-topped ground in the middle of the picture?

I have made it easier for my readers to interpret the picture by adding the “low” and “high” markers. We are looking at two parallel thin mesas about 1,400 feet high, with the saddle between them only dropping about 350 feet.

But what about the dark fluted features? To understand what these are requires more information.

FAA fines SpaceX $633K for acting without its permission

12:46 pm

The FAA to SpaceX
The FAA to SpaceX “Nice company you got here.
Sure would be a shame if something happened to it.”

The FAA today revealed that it wants to fine SpaceX a total of $633,009 for two different actions where the company did something without the agency’s express permission.

In May 2023, SpaceX submitted a request to revise its communications plan related to its license to launch from Cape Canaveral Space Force Station in Florida. The proposed revisions included adding a new launch control room at Hangar X and removing the T-2 hour readiness poll from its procedures. On June 18, 2023, SpaceX used the unapproved launch control room for the PSN SATRIA mission and did not conduct the required T-2 hour poll. The FAA is proposing $350,000 in civil penalties ($175,000 for each alleged violation).

In July 2023, SpaceX submitted a request to revise its explosive site plan related to its license to launch from the Kennedy Space Center in Florida. The proposed revision reflected a newly constructed rocket propellant farm. On July 28, 2023, SpaceX used the unapproved rocket propellant farm for the EchoStar XXIV/Jupiter mission. The FAA is proposing a $283,009 civil penalty.

To understand the absurdity and abuse of power going on here, one must look at the dates. » Read more

A space journalist suddenly notices that the FCC has no legal authority to regulate space junk

9:34 am

An article posted yesterday at Space News was unusual in that this mainstream media space news source and its reporter suddenly recognized, more than a year late, that the FCC’s effort to impose regulations on all satellite companies requiring they build satellites a certain way to facilitate their de-orbit at the end of their lifespan, is based on no statutory authority and is thus illegal.

[A] Supreme Court ruling in June struck down a principle widely known as “Chevron deference,” which gave agencies greater latitude in interpreting ambiguities in laws they enforced. The move has raised questions over the FCC’s space sustainability jurisdiction without a federal law that explicitly authorizes it or other agencies to establish and enforce debris mitigation rules.

Still, the FCC is seen as the logical agency to handle the risk of orbital debris. If courts rule that the FCC has not been granted the authority, Congress will likely address this once it gets around to tackling the issue.

My, my! You mean a federal bureaucrat doesn’t have the right to make law out of thin air, just to facilitate what that bureaucrat thinks should be done? Who wudda thought it!

As an old-fashioned American who believes in freedom and limited government (as clearly established by our Constitution) I had recognized this legal fact immediately in January 2023, when the FCC first made its power grab. That our young modern journalists don’t understand this is both tragic and disgraceful.

What makes this even more disgraceful is that the entire article lobbies hard for the FCC, claiming with no real evidence that “the FCC is seen as the logical agency to handle the risk of orbital debris.”

What this reporter should have known and reported is that both the House and the Senate have disgreed, forcefully. In the House one bill was introduced to give the de-orbit regulatory power to the FAA, while later rejecting a second bill that would have given that power to the FCC. The Senate meanwhile introduced its own bill giving this de-orbit regulatory power to the FAA and Commerce, not the FCC.

Sadly it is probably a mistake to give any government agency too much power in this matter, but our Congress will do so regardless. That is how things are done nowadays. Americans are expected to kow-tow to Washington regulators, in everything they do. Freedom is not the default approach. Regulation is.

France’s space agency aims to standardize its French Guiana commercial launchpad

9:04 am

France’s space agency CNES has announced a project to standardize its French Guiana commercial launchpad, which France owns and CNES now manages, for many different customers.

Launch facilities and launch pads in particular are generally specifically built for a single rocket. This will, however, not be the case with the Guiana Space Centre’s new commercial launch facility. As a result, a set of standardized ground systems will be utilized to ensure that the facility can manage a number of different rockets.

At the moment, those rockets include seven different European rocket startups — Avio, HyImpulse, Isar Aerospace, MaiaSpace, PLD Space, Rocket Factory Augsburg, and Latitude — none of which has yet launched a rocket. CNES is telling them all that if wish to use French Guiana, they must design their rocket to fit its facilities.

This project will accomplish two things. First, it will limit use of the pad to these European companies. CNES is essentially establishing French Guiana as a European-only facility. Second, like China’s commercial launchpads — run by that government so that all its pseudo-companies are dependent on it for launches — CNES (and France) is attempting to establish some control and power over these new independent and competing rocket companies, most of which have no facilities or operations in France. Three are German (Hyimpulse, Isar, and Rocket Factory), one is Spanish (PLD), and one is Italian (Avio). Only two are French-based (Latitude and MaiaSpace), with MaiaSpace a subsidiary of ArianeGroup which means it has facilities in many places in Europe. This project will force all these companies to cater their designs to the demands of France.

The American approach I think is far better. Government spaceports lease specific launchpads to specific companies, which then build the facilities to their needs, not the government’s. They can then each work fast and efficiently without consultation with others. CNES’s effort here will likely slow development in Europe, as all these companies will have to meet with CNES and work out some common engineering.

Russia’s Angara rocket launches pair of classified military satellites

8:47 am

Russia early today used its Angara-1.2 rocket to launch a pair of classified military satellites, lifting off from its Plesetsk spaceport in northwestern Russia.

The Angara-1.2 is the smallest member of the Angara family of rockets, intended to eventually replace all of Russia’s other rockets. This was that rocket’s third launch, all from Plesetsk. The rocket’s upper stages and fairings fell in Barents Sea.

The leader board in the 2024 launch race remains unchanged.

91 SpaceX
38 China
11 Russia
10 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 106 to 60, while SpaceX by itself still leads the entire world, including American companies, 91 to 75.

What the Milky Way would look like if it was presently a star forming powerhouse

9:15 am

A galaxy as seen by Hubble and Webb
For the original images go here and here.

Cool image time! The two pictures to the right, taken respectively by the Hubble and Webb space telescopes of the same galaxy, shows us many different features of a barred galaxy, located about 35 million light years away. From the caption for the Hubble image:

This picture is composed of a whopping ten different images taken by the Hubble Space Telescope, each filtered to collect light from a specific wavelength or range of wavelengths. It spans Hubble’s sensitivity to light, from ultraviolet around 275 nanometres through blue, green and red to near-infrared at 1600 nanometres. This allows information about many different astrophysical processes in the galaxy to be recorded: a notable example is the red 656-nanometre filter used here. Hydrogen atoms which get ionised can emit light at this particular wavelength, called H-alpha emission. New stars forming in a molecular cloud, made mostly of hydrogen gas, emit copious amounts of ultraviolet light which is absorbed by the cloud, but which ionises it and causes it to glow with this H-alpha light.

Therefore, filtering to detect only this light provides a reliable means to detect areas of star formation (called H II regions), shown in this image by the bright red and pink colours of the blossoming patches filling NGC 1559’s spiral arms.

The Z-shaped blue indicates the stars and its most distinct spiral arms. Astronomers presently believe that the Milky Way is also a barred spiral like this, though its star-forming regions are thought to be far less extensive and distinct.

The Webb infrared image matches the Hubble data, with the false color blue indicating the near-infrared and the false color red the mid-infrared. As with the Hubble picture, the red indicates the galaxy’s extensive star forming regions.

Investigation into upper stage failure during Ariane-6’s first launch completed

8:38 am

The Ariane-6 rocket investigation team, including people from the European Space Agency (ESA), CNES (France’s space agency), ArianeGroup (which built and owns the rocket), and Arianespace (which presently manages the rocket), has identified the issue that caused the rocket’s upper stage failure during the rocket’s first launch in July.

In a 16 September update, the Task Force announced that the investigation had identified a single temperature measurement that “exceeded a predefined limit” as the root cause of the anomaly. The tripped limit caused the software to trigger a shutdown of the APU which ensured the rocket’s Vinci upper stage engine could not be restarted for the final burn.

In order to remedy this issue and ensure a similar shutdown does not occur in the future, the ignition preparation sequence, specifically the APU chill-down sequence, has been changed. The updated flight software is already being tested as teams prepare for the rocket’s first commercial flight which is set to take place before the end of the year.

Because of that incorrect temperature, the upper stage did not do its final burn, thereby stranding the stage and two demonstration return capsules in the wrong orbit. This prevented the test return of both capsules, as well as the test planned de-orbit of the stage over the ocean.

Two Russian astronauts mark one year in orbit

11:38 am

Russian astronauts Oleg Kononenko and Nikolay Chub today marked the one year anniversary of their launch in 2023, thus marking another Russian yearlong mission in space.

The two cosmonauts were sent to the orbit aboard the Soyuz MS-24 manned spacecraft, which blasted off from the Baikonur space launch center on September 15, 2023. The third crew member on board was NASA astronaut Loral O’Hara, who returned to the Earth on April 6, 2024. Kononenko and Chub, as well as NASA astronaut Tracy Dyson, will travel back aboard the Soyuz MS-25 spacecraft, whose departure is scheduled for September 23.

Their return next week will not mark a record for the longest flight in space. That belongs to Valeri Polykov, who occupied the Soviet-built Mir space station in the mid-1990s for one year, two months, and two weeks in the mid-nineties, or 438 days. The second longest flight was by Sergey Avdeev, 380 days on Mir in 1998-1999, with the third longest flight by Sergey Prokopyev, Dmitry Petelin, and Franco Rubio, 371 days in 2022-2023.

When Kononenko and Chub return on September 23rd, their flight will 373 days long, passing the 2022-2023 mission.

Note that only one American is on this list. A few have flown almost a year, but only Rubio has made it, and that was forced on him unplanned because of problems with the Soyuz capsule that brought him into orbit. He was forced to stay up an extra six months and come down on the next Soyuz.

The reason for this lack of long American flights is entirely NASA’s fault. It has consistently resisted doing such long missions, even holding the Russians back during the first two decades of ISS’s operation. The Russians no longer follow NASA’s timidity, and have been doing more such missions, because such missions will be the only way to gather the necessary medical data needed for future missions to Mars.

Meanwhile, NASA hesitates, and sometimes touts eleven-month missions (such as Scott Kelly’s) as year-long missions, a blatant lie that our propaganda press repeats mindlessly. I fully expect the first planned year-long American mission will be done privately, outside of our government, once Starship begins flying regularly.
