🚨 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.

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

We are targeting no earlier than August 26 for the launch of Polaris Dawn

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 structure is aluminum, which is protected from reentry heating by a durable fabric thermal protection system we invented and refer to internally as ‘Comet.’ The aerodynamic forces pushing on the fin during flight are roughly equal to the weight of a 737 aircraft.  #newglenn @blueorigin

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 forward to that." (1/2)

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 few days as they work through overall studies ahead of an agency readiness review.

Thanks to the pace we’ve been able to launch, we’re able to gather unprecedented levels of flight data and are poised to rapidly return to flight as soon as Saturday, July 27 → spacex.com/launches/mission/…

Just in and it’s a STUNNER: NASA just announced that is has CANCELED the VIPER rover program designed to search for ice on the Moon The $433.5M rover was slated to launch later this year Very disappointing, considering the rover has been built and was moving on to environmental testing. More to come

After a comprehensive review, we are discontinuing development of our VIPER (Volatiles Investigating Polar Exploration Rover) project. We are committed to studying and exploring the Moon, and will pursue other methods to accomplish many of VIPER's goals: go.nasa.gov/3W0WSWI
