  • Blue Origin faces two discrimination lawsuits
  • Both suits accuse the company of weeding out older employees, exclusively based on age. I wonder if many of those older workers simply had the knowledge and experience to realize working for Blue Origin was turning out to be a dead end.

  • Branson pumps another $5 million into Virgin Orbit
  • Branson has now invested $60 million in Virgin Orbit since November 2022 in order to keep the company above water because delays with licensing at the UK bureaucracy prevented it from doing further launches in 2022. No launches, no revenue. And we now know for sure this is his reason, because his investment deal allows him to pull that money out at any time. Expect him to do so once Virgin Orbit begins flying again and making money.

  • A graph showing the steady and slow decay of Hubble’s orbit
  • The decay was brought up because Hubble now orbits just below SpaceX’s Starlink satellites, and thus some are concerned its work will be hindered by them. I think this is a non-issue. More important is that decay. If Hubble is going to be remain in space, work on a rescue mission must begin soon.

 

 

 

  • Astra identifies the cause of its last launch failure
  • In reading their conclusions, I came away with the impression that this rocket had a lot of weak links, any one of which could cause a failure. No wonder the company abandoned it after this launch to focus on a new rocket.

  • Another version of China’s heavy lift Long March 9 unveiled
  • Having the ability to change is not in itself a bad thing, but indecisiveness can be a curse. At present it is not clear which it is for this particular Chinese rocket project. Jay’s comment: “Dr. Long [the designer] … can’t decide which plans to steal and build.”

Jay asks forgiveness for the lateness today of these quick links, as he was overwhelmed with work at his real job. I say, no apology required. Thank you Jay!

  • Damaged Progress to undock from ISS shortly
  • Live stream is here, scheduled to go live around 6:15 pm Pacific. Following undocking the freighter will be maneuvered so that the leak in its coolant system on its service module can be photographed.

 

  • U.S. military is loosening its rules for bidding on its launches
  • The language in the screen capture at the link is typical bureaucratic blather, but the bottom line is that the military is no longer limiting bidding on launch contracts to just SpaceX and ULA, a foolish program I have begging the military to abandon for years. At this point they will let others bid on missions that are less risk tolerant. Expect with time this policy to loosen even more, as more competition can only save the military money, while providing it more redundancy and capability.

  • Russia resumes prepping next Soyuz for launch
  • An inspection of the outside of the spacecraft’s cooling system found no damage or drilled holes. Expect the launch to occur before the end of February, relative close to its previous launch date of February 19th. As this is the lifeboat for three occupants of ISS, delaying its launch increases other risks.

  • Blue Origin says it has made both solar cells and electricity transmission wires from simulated lunar soil
  • The article claims this is a major breakthrough, but I am sincerely underwhelmed. Though eventually such technology might be important for lunar colonists, right now it makes no sense to spend private capital on it. For at least the next two decades, power on the Moon is going to from solar panels shipped there. Other companies such as Astrobotics are developing cheap and easy-to-ship-and-install panels for those first missions, and they, not Blue Origin, are going to reap the profits.

 

 

  • Pseudo Chinese rocket startup Space Pioneer gearing up for first launch of Tianlong-2 rocket by end of March
  • If successful, it would be the first liquid fueled rocket by a Chinese pseudo company to reach orbit. Others have tried and failed.

  • An update on the Epsilon F6 failure last October.
  • The release at the link is entirely in Japanese. According to Jay, “As of February 3 JAXA has now narrowed the cause of the RCS [reaction control system] failure to blockage of the diaphragm at the helium tank outlet.”

 

No blacklist column today. Been too busy with personal matters.

  • Webb found an asteroid by accident during instrument calibration last year
  • I read this press release this morning, decided the story was mostly NASA fluff designed to sell Webb, and rejected giving it a full post. Discoveries like this happen all the time with all telescopes. Webb didn’t do anything special here. However, Jay is right that it deserves some mention, so here it is as a quick link.

  • European startup The Exploration Company raises $44 million to develop reusable spacecraft
  • They hope to do fly a small demo prototype this year. Jay describes the future planned fullscale spacecraft: “The vehicle is called Nyx, I guess it was named after the Greek Goddess of the night. From the article: ‘Nyx would be able to send 4,000 kilograms to orbit for up to six months, and bring 2,600 kilograms back down for 20,000 euros per kilogram.'”

  • 2022 was a profitable year for space insurance companies, the third in a row
  • Jay notes this interesting detail from article: “Many LEO operators including SpaceX are choosing to forgo insuring satellites, not least because the size of their constellations gives them built-in redundancy. The estimated lifetimes of satellites in LEO are also far shorter than their cousins in GEO.”
