I wanted to share some updates:

– The primary factor driving the launch timing for Polaris Dawn is the splashdown weather within Dragon's limits. Unlike an ISS mission, we don’t have the option to delay long on orbit, so we must ensure the forecast is as favorable as possible… pic.twitter.com/3cKEjjVqvC

…from a common blood-pressure medication? I should try that.
Dubious Medical Norms
Medicine is much less scientific than they would have you believe.
A Rare Event
I noted several years ago that SpaceX had made landing boosters routine, so much so that it was news not when they landed, but when they failed. On this morning’s flight, there was news.

It was a long-lived booster, with twenty-three flights under its belt. It will be very interesting to see what caused it, and if it was fatigue. When I was at the Cape three weeks ago, I was told that the original goal for reuse was ten flights, but with multiple boosters exceeding twenty, the new goal was forty. We’ll see if there is some life-limiting issue that can’t be maintained around.
[Late-morning update]
This is ridiculous.
This statement from the FAA says it’s requiring an investigation stemming from the Falcon 9 booster hard landing last night. “A return to flight” would come after a completed investigation, so it looks like Polaris Dawn may have to wait a while longer if I’m reading this all… pic.twitter.com/aiUjfeVCdb

I could understand their saying “No RTLS until you figure out what happened.” But to stand down launches over a landing failure? How can they justify that?
[Afternoon update]
Bob Zimmerman is less than impressed as well.
Where No Woman Has Gone Before
It looks like Polaris Dawn is finally about to launch.
Everyone has noted that this will be the highest-altitude flight since Apollo, but all of the Apollo astronauts were men. Menon and Gillis will hold the altitude record for women after this, until a woman goes to the moon (which may or not be on Artemis, given the ongoing boondoggle).
Lord help us, the new cost estimate of NASA’s Mobile Launcher-2 project is now a mind-boggling $2.7 billion.https://t.co/KE7WZEtcQ5

[Update a while later]
Bob Zimmerman has thoughts on the latest SLS fiasco.
[Wednesday-afternoon update]
I weep when I consider what *actual useful* space hardware we could have for $2.7B. https://t.co/USS3NwXBFx

Ukraine’s Invasion Of Russia
I agree that the most significant aspect of this is that there have still been no nukes. I wonder if Putin is concerned that either they’re no longer functional, or that he can’t trust his underlings to use them.
Rapid Reusability
Now that’s what I call turnaround:

Is it an auto-immune disease?
I think we’re going to discover that many diseases are auto-immune diseases, and that may be the key for dealing with them.
