The difference in treatment between this story of the Chinese stranded taikonauts and the US melodrama/passion/political confrontation around the Suni and Butch Starliner problem is absolutely astounding.
🇨🇳🚀China always prepares a backup rocket for every manned space launch in case of emergencies that might require a rescue, ensuring astronauts do not get fatally stuck in space for months. The Shenzhou-22 just launched without astronauts inside, is actually the backup for

To anyone who thinks it’s an “exaggeration” that the rule of law is in danger… U.S. Senator Mark Kelly is being investigated for the “crime” of telling people not to commit crimes. We’ve fallen far.

Michel Onfray fait de l’astrophysique. Et c’est, comment dire, très approximatif.
🤡🤡🤡🤡🤡 "l'astrophysique nous enseigne que il y a un réchauffement climatique qui est du à ce qu'on appelle les plurivers, les multivers, les interactions entre les univers mais pour ça il faut faire un peu d'astrophysique" #cnews

Anx this is why you should 1) curate the accounts you follow 2) systematically mute the accounts that are a PITA 3) avoid the ’for you’ feed (biased and manipulative) but stick to’following’ instead. This way you chose what you see. Who needs algorithms anyway?
X openly saying they tip the scales and choose what you see. Instead of taking sides based on whose team won the last cycle, we need to fix the structural problem of one boss making the decisions — history shows us where that leads

The usual simplistic takes... if only half of that was true. Scaling stuff in space is exponentially difficult.
1m² of solar in space generates 10x more energy than it does on Earth. That’s because in space there is no night, no clouds, and no thick atmosphere. A solar array 1km² in space would produce as much power as a nuclear reactor. It’s why space datacenters make sense.

When the development costs pile up into billions before Starship is ready the whole narrative of the super low cost launcher doesn’t really work anymore, unless you assume that they will never be amortised: 10B$ in dev cost is 10M$ per flight spread over 1000 flights.
@DrChrisCombs The rapid iteration approach doesn't seem to be working, it just might be too big for it. SLS: 14 yrs to 1st successful full test flight. $11.8 billion to date Starship: 9 years from announcement hasn't gotten to orbit. Cost at least ≈ $7 to 10 billion to date

At this very slow rate of build and launch when will $ASTS start generating revenue?

“I don't think they have made a lot of progress, but I don't think it's going horribly,” one of the U.S. officials told Reuters (about Golden Dome).

Starship booster 18 ground test failure: a good compilation of posts with pictures and explanations by @Cosmic_Penguin , the damage is impressive. This will probably delay the next Starship IFT a few weeks, or months?
Hmm...I think it will buff out. Perhaps even "just" replacing the LOX tank section with new parts ("unweld"/cut then reweld) will do in the worst case. https://t.co/0gMu8Tc0pq

Germany plans to significantly increase funding for the European Space Agency (ESA), with Research Minister Dorothee Baer set to pledge up to €5B ($5.76B) at the ESA's conference in the north-western city of Bremen next week. https://t.co/lcK2ypyG9R

Thank you @SpcPlcyOnline And for the laziest of us the space chapter is available at the link below. Check out also the Executive Summary. https://t.co/gatLm3kR2U
The 2025 report from the congressional U.S.-China Economic and Security Review Commission is out today with a lot to say about space. Executive Summary: https://t.co/wBKU2yELCI Links to today's hrg, full report etc. https://t.co/xCxKcwZduO

Where are the profits in the European space industry? I published an article with findings of an analysis of profitability of space businesses in Europe. Link in next post.

.@ST_World who already built the PCBs for @Starlink's Gen1 user terminal, unveils the STM32V8, a new generation of 18nm high-performance microcontrollers (MCUs) selected by @SpaceX for its mini laser system on Starlink satellites, quotes @michaelnicollsx: https://t.co/Wqu3iHWfwO
.@DaveMosher reports @SpaceX has contracted @ST_World already "a few years ago" to build 1m #Starlink user terminals at $2400/pc, hence current hardware subsidy for beta testers is $1900. Article suggests, SpaceX may be paying $2.4 billion for the order. https://t.co/jak0hKQBGn

@LionnetPierre Connectivity will get only a small fraction of GDP in any area - and as it is lower priority in Maslow terms, is even more marginalised in poor areas. GEOs, while not trendy, at least can be tailored to markets while LEOs cannot. That’s why LEO=Least Efficient Orbit

And that is why LEO broadband infrastructure has strongly declining marginal profitability.
There are very few people on Earth. Living in a big city gives you the illusion that Earth is full, but most of Earth is empty of people.
