China’s reusable stainless steel Falcon 9 inspired rocket is being assembled, before its maiden launch later this year. Zhuque-3 is made by LandSpace and has 9 nine methane engines on the first stage ond one Vacuum engine on the second stage

Isaacman says he has received assurances from HLS companies Blue Origin and SpaceX that their landers would be ready for low Earth orbit tests on Artemis 3 in late 2027. (NASA had been talking about Artemis 3 around mid-27.)

NASA Administrator Jared Isaacman is back on Capitol Hill for a budget hearing by the House CJS appropriations subcommittee.

🛰️👨‍🚀 Un sauvetage époustouflant : pour sa première mission, la navette Endeavour devait sauver le satellite Intelsat 603, bloqué en orbite depuis son lancement raté deux ans auparavant. Pas moins de trois sorties extravéhiculaires ont été nécessaires. 📹 : Vidéo accélérée 14x.

@WalterIsaacson Walter, please ask Elon to put the starship streams back Youtube. Important to inspire the next generation. Kids are not on X

All of this is amazing, but I am particularly blown away by the new version of the raptor engine.

Three years since the first flight of Starship, the next generation is here. New ship. New booster. New engines. New pad and new test site. SpaceX engineers are working to solve one of the most difficult engineering challenges in history: developing a fully, rapidly reusable rocket

@KirstenGrind @susannecraig a move that would have been illegal at a public company

NEW: Elon Musk took $500 million in loans out at SpaceX, a move that would have been illegal at a public company. It's just one example of the years of financial engineering at the helm of his companies. Latest investigation with @susannecraig nytimes.com/2026/04/24/tec…

🚨 Sir Alex Ferguson on modern football debates: 🗣️ Ferguson: “People talk a lot about tactics today, and of course the game has evolved in that sense. Managers are more detailed, teams are more structured, and everything is analysed more than ever before. But at the end of the day, football will always come down to players and mentality. At Manchester United, we focused on building winners. That wasn’t just about ability, it was about character, how players handled pressure, and how they responded when things weren’t going their way. You can have the best system in the world, but if the players don’t have the belief or the personality, it won’t last. There were many games where tactics didn’t win it for us. It was the attitude, the refusal to lose, the willingness to take responsibility in big moments. That’s something you can’t always teach, but you can build it into the culture of a club. That’s why, no matter how much football changes, the most important things will always stay the same. Players win matches, mentality wins trophies. That’s what lasts.”

@Lori_Garver It is not that individual astronauts should not advocate for political issues, but when they say, “we as astronauts believe this,” it can backfire. Astronauts have a certain status that they should not abuse. That is what happened when 50 former intelligence officials weighed in

Fascinating attempt to utilize public notoriety of astronauts to impact elections. Reports say the org will use scorecards to assess candidates/incumbents on their adherence to the rule of law, civil discourse & bipartisanship. Intriguing since astros typically abhor politics.

I know all of these people. Been is space with some. Worked with others for decades. They’re really smart, thoughtful, and stand firm on the foundational principles of this country.

@ScienceXnews @SpaceDavenport @WSJ And the alternative is what... Not advocate/lobby for that issue?

@PettyKang @mclumber1 @Alexphysics13 Ouch

@ScienceXnews @mclumber1 @Alexphysics13 They were extremely bulky and very harsh on the joints. Astronauts typically lost all of their fingernails.

From the report’s findings: “Based on our analysis, if Axiom experiences design and testing delays in line with the historical average for recent space flight programs, the Artemis and ISS demonstrations may not occur until 2031.”

@PettyKang @mclumber1 @Alexphysics13 How so?

@mclumber1 @Alexphysics13 Because the suits used for the Apollo mission were absolute trash.

@TJ_Cooney Ask him to put the starship stream back on youtube

Oh my gosh what do I say to him

@peterrhague Elon bad

Bit odd they didn’t name the launch provider

What the hell happened to twitter search? You cant search things anymore. It just shows random stuff?

What year will humans land on the moon again?

What year will humans first fly on Starship?
