NASA is developing a second mobile launcher (ML-2) to support larger variants of the Space Launch System. NASA estimates the ML-2 will cost $1.8 billion, over three times more than planned, despite efforts to improve project performance. Read the full report: oig.nasa.gov/office-of-insp…
Nothing more relatable these days than a rocket that just suddenly falls apart in space
🚨 We’re actively monitoring and analyzing the breakup event in #LEO involving a Chinese rocket body, CZ-6A. Our radar data indicates this event occurred on 6 August at ~20:10 UTC at ~810 km. It resulted in at least 700 debris fragments and potentially more than 900.
Reading between the lines: Ship 30's Spin Prime completed the testing requirements post-engine swap out. Booster 12 is ready to go and waiting for rollout. B14.1 is the additional booster catch testing, with upcoming slap and clap tests. Ship 31 is undergoing TPS replacement (like Ship 30). Could additional Flight 6 testing point to Booster 13 Static Fire before Booster 12 goes to the pad for integrated stack testing (WDR)? Flight 5 likely in the September weeks now.
Flight 5 Starship and Super Heavy are ready to fly, pending regulatory approval. Additional booster catch testing and Flight 6 vehicle testing is planned while waiting for clearance to fly
NASA continues to face significant cost increases and schedule delays as it develops the more powerful version of its Space Launch System heavy-lift rocket known as Block 1B. Read the full audit report: oig.nasa.gov/office-of-insp…
🚨 Slingshot Orbital Alert 🚨 Following China's launch of 18 G60 satellites on August 6th, Slingshot is tracking over 50 pieces of space debris that pose a significant hazard to LEO constellations below 800 km altitude.

Truly a wild Starliner press conference: -- NASA finally went into detail about a SpaceX contingency plan for bringing Butch and Suni home -- People within NASA do not agree on which path to take -- They need to decide by mid-August on how to move forward bloomberg.com/news/articles/…
Good morning, Dave
This forward module validation test is fun to see. Our four fins on New Glenn are about the size of a car—roughly 16 feet long at the base and sticking out 6.5 feet from the body of the rocket. They’re responsible for steering the rocket on ascent and descent. Most of the

Cygnus NG-21: At ISS crew wakeup today, Mike Barratt asked mission control if the onboard Cygnus capture timeline for Tuesday was still good or if a revision was expected. The MCC CAPCOM replied, "it's a good timeline for tomorrow." Barratt: "OK, superb, we're really looking
NASA and Boeing's careful parsing of their work on Starliner has walked the line of transparency, but if the agency did just lie to reporters about the July 14 study, as @SciGuySpace reports here, it will be a major blow to its credibility. arstechnica.com/space/2024/08/…
A homepage I am sure the staff of the @WSJ has been dreaming of publishing:
Preliminary results from the July 27 #Starliner tests show all the tested thrusters are back to preflight levels based on thrust and chamber pressure. For additional details about the test: go.nasa.gov/3zWHTFN
The #Starliner crew and ground teams completed a test of the spacecraft’s reaction control system thrusters today. The jets were fired for short bursts, one at a time, to provide data for analysis of the systems. Teams will evaluate the results of the test firings over the next
