April 29, 2024 Quick space links
Courtesy of BtB’s stringer Jay, who has returned from a weeklong work trip in “the People’s Republic of California.” This post is also an open thread. I welcome my readers to post any comments or additional links relating to any space issues, even if unrelated to the links below.
- SES’s O3b mPOWER satellite constellation starts providing service
That makes at least three constellations (including Starlink and OneWeb) in orbit ahead of and operational before Amazon has launched a single satelltie in its Kuiper constellation
- Hyimpulse’s suborbital test launch from Southern Launch in Australia is now targeting May 2, 2024
Though I saw no announcement, they apparently got their launch licence from the Australian government.
- Long March 5 ready to launch China’s Chang’e-6 sample return mission to the Moon’s far side
According to the article, the core stage will not reach orbit and thus not make an uncontrolled re-entry, as the core stage of the more powerful Long March 5B varient does.
- Chinese reporter notes the increase in hotel prices near the Wenchang spaceport when a manned launch is scheduled
The communists might claim they think capitalism is bad and they are building a Marxist utopia, but the invisible hand of capitalism always rules.
The new Nazis and the coming genocide they are planning
The Nazi desecration of babies held hostage
by Hamas
Unless you have been badly educated at one of the so-called elite universities in the United States, Great Britain, or Europe, the genocidal goals of the terrorist organization of Hamas in Gaza are as plain as day. These murderous thugs not only admire Hitler and wish to finish his effort to wipe out all Jews, they demonstrated that blatant evil goal on October 7, 2024, killing more than a thousand men, women, and children, torturing and raping many women and children in the process. Hamas’ victims that day had committed only one crime: being Jewish and living near Gaza. Many were from the leftwing secular Israeli community, and had worked hard to build good will ties with many in Gaza. The Gazans, working for Hamas, used those ties to gather intelligence that was then used to murder these Jews.
Soon after the massacre, Hamas officials went on television to celebrate these vicious murders. Ghazi Hamad of the Hamas Political Bureau proudly said said that the slaughter on October 7th “is just the first time, and there will be a second, a third, a fourth.” When asked if his position called for the anniliation of Israel, he immediately answered “Yes, of course,” adding “No one should blame us for the things we do, on October 7, October 10, October million, everything we do is justified.”
So what does these goals tell us about the hoards of protesters now swarming on many of these same college campuses, screaming things like “Globalize the Intifa!” and “Kill the Zionists!”? The picture above tells us all we need to know. On October 7th Hamas not only killed more than a thousand, it kidnapped more than two hundred more to hold as hostages, many of whom were little childen and babies. When supporters of Israel began putting up these posters showing the actual hostages held and demanding their release, supporters of Hamas in America and elsewhere would routinely go around ripping those posters down. In the case of the poster above put up in London, they did worse, actually drawing Hilter mustaches on the faces of the babies.
On campuses now, these student protesters are daily telling us where they stand. They support Hamas unequivocally, and want it to survive to kill Jews. Like the Nazis in Germany, they work to harass and persecute any American Jews who happen to stroll by, sometimes acting to block their access to the university. In some cases they attack them violently.

Why the release of the EU’s own space law has been delayed
In the fall of 2023 officials of the European Union (EU) announced that they expected to release the Union’s own space law, that would regulate the individual space laws of all member nations. Since then the release of that law has been put back several times, and in early April its release was delayed until the summer, after the EU elections in June.
This article published today provides the likely reasons why it has been delayed. Apparently, individual members of the EU have objected to the law as interfering with their own space laws as well as imposing regulations they don’t want or need.
The EU Space Law will need to overcome several obstacles to become a functional and beneficial piece of legislation. Several EU Member States already have national space legislation and are actively engaged in space activities, while an increasing number are adopting domestic frameworks and expanding their presence in the space sector. In a heavily regulated environment, where countries have long established and enforced national laws, the practical implementation of a space law at the EU level may be contested.
The article then lists three reasons for these objections. First, the EU has no experience or stake in this matter. It launches nothing and thus can only pose an additional obstacle to the growing commercial space industries in member countries. Second, an EU space law is certainly going to conflict with the space laws of member countries. Third, this law’s implementation could significantly interfere with the legal timelines established by individual member countries.
The article also lists three reasons why the EU law might be good, but these reasons really can be summed up as attempting to justify the EU’s power grab over the space efforts of the member countries.
In the end, this analysis tells us that the EU’s power grab has been met by significant opposition behind the scenes, and could very well die because of that opposition. Germany, Italy, Spain, and more recently even France have begun to encourage the development of independent competing rocket companies, and all likely fear this EU space law will only get in the way.
The plan for SpaceX’s first demo in-orbit refueling mission of Starship
Link here The details come from a presentation at a public meeting by Amit Kshatriya, Deputy Associate Administrator of NASA’s Moon to Mars program, with this the key takeaway:
Kshatriya then expanded the discussion beyond the next few Starship flights and talked about the required technologies for a fuel depot in orbit and the in-orbit capabilities needed to transfer fuel. “We need an instance of the ship that is essentially long, has the endurance to stay in orbit long enough for the sequence to work.
“So, we need a ship that has at least three to four weeks of endurance in orbit. That endurance is gained through augmented power system capability, augmented battery capacity, full insulation of the cryogenic systems, vacuum jacketing of all the lines, et cetera, to make sure that the cryogens that are being stored or are meant to be stored don’t boil off.”
The challenges of a cryogenic ship in orbit include the need to prevent boil-off from the stack. To facilitate the journey to the Moon’s surface, Starship will have to be refueled. For this, the company plans to refuel a depot in low-Earth orbit (LEO), which would be resupplied by several tanker Starships. The HLS Starship would then dock with this depot before departing for the Moon.
To prove this system will require a Starship test flight that lasts several weeks in orbit, to prove the capability needed for a lunar mission. It will also require a refueling mission that will require several Starship/Superheavy launches, one to put the fuel depot into orbit, several more to fuel that depot, and a final launch of Starship for its refueling and endurance test.
According to the update, SpaceX is still aiming to be ready of the upcoming fourth Superheavy/Starship demo orbital flight in the first two weeks. The NASA official claimed it would occur no later than the end of May. I see that as a confirmation that NASA really doesn’t expect the FAA to issue a launch permit when SpaceX is ready, and that the permit might not arrive in time for a May launch. This statement is meant to soften the blow when the launch finally gets delayed into June, or later.
Whether the many required later Starship launches as described above can get FAA approval quick enough to prove out this system soon enough to meet NASA’s 2026 present target date for its manned lunar landing seems very unlikely. Moreover, even if it does it will be a major challenge for SpaceX to meet this schedule.
Webb takes an infrared look at the mane of the Horsehead Nebula

Click for original image.
The cool infrared image to the right, cropped, reduced, and sharpened to post here, was taken by the Webb Space Telescope and released today. The three pictures above provide the context, with the rectangle inside the rightmost image indicated the area covered by the close-up to the right.
Webb’s new images show part of the sky in the constellation Orion (The Hunter), in the western side of a dense region known as the Orion B molecular cloud. Rising from turbulent waves of dust and gas is the Horsehead Nebula, otherwise known as Barnard 33, which resides roughly 1,300 light-years away.
The nebula formed from a collapsing interstellar cloud of material, and glows because it is illuminated by a nearby hot star. The gas clouds surrounding the Horsehead have already dissipated, but the jutting pillar is made of thick clumps of material and therefore is harder to erode. Astronomers estimate that the Horsehead has about five million years left before it too disintegrates. Webb’s new view focuses on the illuminated edge of the top of the nebula’s distinctive dust and gas structure.
In the close-up, note the many distant tiny galaxies, both above the mane as well as glowing throught it.
SpaceX launches 23 more Starlink satellites
March on bunny! SpaceX today successfully launched another 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.
The first stage completed its thirteenth flight, landing on a drone ship in the Atlantic.
The leaders in the 2024 launch race:
44 SpaceX
17 China
6 Russia
5 Rocket Lab
American private enterprise now leads the rest of the world combined in successful launches 51 to 29, while SpaceX by itself still leads the rest of the world, including other American companies, 44 to 36.
SpaceX launches two Galileo satellites, part of Europe’s GPS-type satellite constellation
SpaceX today successfully launched two satellites of Europe’s Galileo GPS-type satellite constellation, the first of a two-launch contract awarded to SpaceX when the Soyuz rocket was no longer available because of Russia’s invasion of the Ukraine and Arianespace’s Ariane-6 rocket was not yet operational.
The first stage completed its 20th flight, tying the record set by another booster only a few weeks ago. Because of the high orbit required by both satellites, that stage was not recovered, the first time SpaceX has expended a first stage since November 2022. SpaceX however also announced that the company is now working to upgrade its Falcon 9 first stages and fairings to fly as many as 40 missions. The two fairings also completed their fourth flight, which brought the total of fairings SpaceX has recovered to 200.
The leaders in the 2024 launch race:
43 SpaceX
17 China
6 Russia
5 Rocket Lab
American private enterprise now leads the rest of the world combined in successful launches 50 to 29, while SpaceX by itself still leads the rest of the world, including other American companies, 43 to 36.
ESA shuffles the management and structure of its ClearSpace-1 space junk removal mission
The European Space Agency (ESA) this week did a major shake-up in the management and structure of its ClearSpace-1 space junk removal mission that had previously been awarded to the Swiss orbital tug startup Clearspace.
Moving forward OHB SE will take over the responsibility of leading the ClearSpace-1 consortium. The Bremen-based company will provide the satellite bus and will be in charge of system integration and launch. ClearSpace will be responsible for the close proximity and capture operations once the vehicle is in orbit.
In addition to the change in leadership, the mission’s target has also been adjusted, with ClearSpace-1 now expected to rendezvous and capture PROBA-1. The 94-kilogram ESA technology demonstrator was launched aboard an ISRO PSLV rocket in October 2001.
The original target, a payload adaptor from a 2013 Vega launch, had been hit by another piece of junk, damaging it and making it a much more difficult target to grab, using the four grapple arms of the Clearspace spacecraft. No timeline for when this revised mission will fly was announced.
A molecule found by Rosetta on Comet 67P/C-G proves discovering life on exoplanets will not be easy
The uncertainty of science: Scientists have long assumed that the molecule dimethyl sulfide (DMS) is an excellent biosignature of life, since it is only produced by life here on Earth. When they discovered it in the atmosphere of an exoplanet last year many thought, especially in the media, that it proved that life existed on that exoplanet.
A scientist who had worked on the Rosetta mission to the Comet 67P/C-G thought otherwise, that DMS was not a reliable biosignature and quickly proved it.
Just 1 day of data from Rosetta’s mass spectrometer, an instrument that can identify molecules by their specific weights, was enough for [Nora Hänni] and her colleagues to find DMS. She says lab experiments will now be needed to pin down exactly how DMS forms in space, where ultraviolet light and cosmic rays can power the synthesis of complex organic molecules. Another important question is whether comets could deliver significant amounts of DMS to a planet—and perhaps account for detections like the K2-18b claim. “If it impacted the atmosphere, it could contaminate the atmosphere of the planet,” Noack says, potentially complicating searches for alien life.
Like the fake news in 2020 that life was found in the atmosphere of Venus (it wasn’t), it is a big mistake to use the detection of one molecule to assume it is evidence of life on an alien world. The universe is far more complicated.
