I find the acronym for NASA’s Aerospace Safety Advisory Panel ironic in the extreme.
They really are obsessing about the chutes.
Simplest calculation:I wonder how many G’s the crew would experience during the acceleration described here?

Your math is better than mine. I couldn't be bothered to go back and redo the numbers when it was apparent my ending speed didn't match the quote
(edit: I should also point out how non-linear the actual acceleration will be just due to the rocket equation, i.e. that mass is dropping constantly til the motors burn out, so my numbers are pretty far off)
(and this, folks, is why I never did very well in physics)
I would not describe that statement by Bridenstine that way. I think it’s a slam on SpaceX and it’s over the line. Bridenstine is basically saying that SpaceX is not giving proper attention and resources to Crew Dragon but is instead focusing on Starship. Which strikes me as ridiculous. I’m sure that the Crew Dragon team is doing everything they can to accomplish their objectives and we have no evidence that resources are being diverted to Starship.Yesterday he felt compelled to issue a slight dig.
Indeed!I would not describe that statement by Bridenstine that way. I think it’s a slam on SpaceX and it’s over the line.

Yes, I noticed that, and thought Elon was being very diplomatic in his response.Indeed!
From tonight's talk, Elon said only 5% of resources are directed toward Starship.
I don’t think that is the explanation. His tweet was squarely aimed at SpaceX. I think it is possible that Bridenstine was being directed by a higher authority...what was the point of Bridenstine's tweet? If anything, it allows people, like Eric Berger, to point out how wasteful NASA has been with SLS. I don't know, maybe Brindenstine is playing 8 dimensional chess here and that was the outcome he was hoping for.
Daaaaamn son!In a CNN interview last night, the reporter brought up the Bridenstine statement quoting “Commercial crew is years behind schedule.”
Elon’s tongue-firmly-in-cheek response: “Did he say Commerical Crew or SLS?”
