May 19, 2025 Quick space links
Courtesy of BtB’s stringer Jay, who apologies for their lateness. 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.
As I noted to him when he sent these links, I had read all these stories and considered them bottom of the barrel and not worth a full post. They do rate however as quick links.
- Startup Venus Aerospace does successful suborbital test of its “Rotating Detonation Rocket Engine”
Video here. This is still not much more than at the large model rocket stage, but the potential is great.
- Jared Isaacman posts two tweets (here and here) noting how budgets are limited and we must face the reality of NASA budget cuts.
He specifically slams SLS and the issuance of two lunar lander contracts, to SpaceX and Blue Origin. Says we can’t afford it, while robbing NASA of money it could use for “dozens of scientific programs.”
He must be confident he has enough confirmation votes in the Senate or he wouldn’t say these things now.
- Headline: “SpaceX launches 1,000th Starlink satellite of the year during Friday morning mission”
This was the May 16, 2025 launch. Jay calls this an “insane headline,” adding “I remember back when there were only about 1000 active satellites total, as in for the whole world.”
- Russia & China ink agreement for Russia to supply a nuclear power source for Chinese lunar base
Anatoly Zak I think correctly notes, “I think that ‘collaboration’ was actually a simple purchase of the Russian hardware with no Russian access to the resources of the project.” Russia has a very limited ability to send much of anything to China’s lunar base. It will deliver some hardware and let the Chinese deliver it to the Moon.
- On this day in 2009 the last shuttle servicing mission to Hubble ended, with the robot arm releasing the telescope after major repairs
At the time Hubble’s engineers estimated the repairs would give the telescope a minimum of another five years of operation (see the afterword in the paperback edition of The Universe in a Mirror for more details). It is now sixteen years later. The telescope is still functioning but it is also definitely on thin ice, with only two working gyroscopes.
