...revealed that the explosion of the Starship’s upper stage this past November during its second test flight was caused by a propellant dump gone wrong. Despite this setback, the incident will not impact the megarocket’s upcoming scheduled flight in February...

...this venting procedure would normally be unnecessary. Typically, with cargo on board, the Raptor engines would consume all the fuel during its second stage lifting, eliminating the need for venting. However, the empty Starship resulted in surplus propellant that had to be discharged. Encouragingly for SpaceX, this isn’t a major problem, and the issue shouldn’t affect the next launch. ...
 
Good luck, Japan!


Japan is on the verge of a historic attempt to land its robotic “Moon Sniper” explorer on the moon, which could make it the third country this century — and the fifth ever — to put a spacecraft safely on the lunar surface.​
The Japan Aerospace Exploration Agency’s uncrewed Smart Lander for Investigating Moon, or SLIM, mission is expected to touch down on the moon at 10:20 a.m. ET Friday (12:20 a.m. Saturday Japan Standard Time). The spacecraft will start descending toward the lunar surface at 10 a.m. ET, and the event will be streamed live on YouTube in Japanese and English.​

We're back!


Intuitive Machines’ IM-1 lander, also called Odysseus or “Odie,” is on the lunar surface after experiencing unexpected issues hours prior to landing.​
“I know this was a nail-biter, but we are on the surface, and we are transmitting,” Intuitive Machines CEO Steve Altemus announced on a live webcast. “Welcome to the moon.”​
The landing is a historic one, marking the first commercial spacecraft to soft-land on the moon, and the first US-made vehicle to touch down on the lunar surface since the Apollo program ended more than five decades ago. This mission is of key interest to Intuitive Machines’ primary customer, NASA, which is seeking to scout the moon using robotic explorers developed by private contractors before sending astronauts there later this decade through its Artemis program.​
