Scoop – SpaceX has had some recent changes to leadership of its rocket business, with a pair of VPs and a senior director leaving the company, sources told CNBC:
cnbc.com/2021/11/22/elo…
VP of propulsion Will Heltsley has left, sources said, having been with the company since 2009 – Heltsley was taken off Raptor due to a lack of progress, demonstrating the intense pressure given the engine's importance to Starship.

On the SpaceX mission and launch operations team, VP Lee Rosen and senior director Ricky Lim both left – with Rosen having been there since 2013 and Lim since 2008.

A handful of other long-time employees left after SpaceX closed its purchase offer on Friday, timing which people familiar with the matter indicated was in part tied to employees’ stock vesting schedules.

Tonight SpaceX is scheduled to launch the DART mission for NASA – a first of its kind planetary defense test, with a spacecraft that will intentionally smash into an asteroid:

"This is just the coolest mission."
cnbc.com/2021/11/23/spa…
The DART spacecraft was built by @JHUAPL, with @RedwireSpace contributing the navigation system and two roll-out solar arrays, while @ASI_spazio built the LICIACube satellite that will image the collision.

Here's a video overview: cnbc.com/2021/11/23/spa… $RDW
@JHUAPL @RedwireSpace @ASI_spazio After launching, the DART spacecraft will spend 10 months traveling to a pair of asteroids, Didymos and Dimorphos.

Then, in September or October of 2022, DART will smash into the smaller Dimorphos at about 15,000 miles per hour:

The U.S. Court of Federal Claims releases its opinion on the Blue Origin HLS lawsuit ruling, saying that the company "does not have standing because it did not have a substantial chance of award" and, even if it did have standing, "it would lose on merits:"
This opinion is the context to the judge's ruling in Blue Origin's lawsuit earlier this month:
The administrative record for this case was 135,000 pages, and Blue Origin argued that still "documents were missing."

Elon Musk says that SpaceX hopes to complete work on the Starbase launch pad and launch tower "later this month," with more tests in December and "hopefully" an orbital Starship launch attempt in January.
Musk: "In order for life become multiplanetary we'll need maybe 1000 ships or something like that."
Musk emphasizes that NASA selected Starship for the HLS program: "Because of the mass transport capabilities ... to actually have a permanently occupied base on the Moon."

NASA's Inspector General projects the Artemis 1 mission will not launch until "summer 2022," while delays on the HLS program and new spacesuit development mean it will be "several years" later than expected until the agency lands astronauts on the Moon: oig.nasa.gov/docs/IG-22-003… Image
The OIG report comes a week after NASA officially delayed Artemis III, the crewed lunar landing, to 2025:
IG also projects the first four SLS missions with Orion will cost NASA "$4.1 billion per launch." Image
