Sentinel-6B is coasting before 1 additional MVAC burn - the F9 booster that carried the satellite into orbit has returned to a successful landing near the launch site...
Launch less than 15 mins from now if conditions stay green...

Per Reuters: China's CCTV says preps have begun to launch Shenzhou-22 empty to replace space-debris damaged SZ-20 capsule that's still attached to the Tiangong space station. The SZ-20 crew came home in SZ-21's capsule. SZ-21 crew still aboard; need lifeboat + safe ride home. x.com/ReutersScien...

HiPOD: Colorful Bedrock in the Central Uplift of an Impact Crater
This bedrock has greater compositional diversity than the surface layers, because they are from greater depths, older, jumbled, and altered, and very diverse.

Interesting Raptor explosion at McGregor tonight. Seemed to happen during startup - timing we've never seen before.
As always this could be intentional (McGregor's the place they do tests to destruction), or just an unhappy raptor.

Just over eight minutes later, the booster returned to planet Earth, landing on the “A Shortfall Of Gravitas” droneship, stationed downrange in the Atlantic Ocean.
This completes the 563rd mission of a Falcon 9 rocket and is SpaceX’s 150th mission of the year.
