Anybody know of any references that talk about how to determine your delta v budget to deal with launch velocity errors and mid-course corrections?
It will be interesting to find out what their price is. Falcon 9 launch is $15 million a seat if you fly 4, $20 million if you fly 3. Dragon refurbishment cost is unknown, but this could cut the cost to $40 million (ish) a seat. Probably will fly on Resilience...

This is one I've been working on for a while. Thanks to @SciGuySpace for posting the scorecard that I used in this part. It was one long video but it needed to split into parts. youtu.be/7mm3eLrFlf8

I am hoping that Starliner will fly and fly safely. Mostly because I'm tired of the endless "will they or won't they" plot line. I don't mind a little suspense, but 4 years is too many years.

Does it seem weird to you that a company that wants to "enable millions of people to live and work in space" has spent $0 sending people to live and work in space?
This is obviously cool to watch. Note the huge stabilizing arms around the nozzle to keep it from flexing all over the place, like this: youtube.com/watch?v=hDCCBg…

I'm confused that people are asking why SpaceX is optimizing Starship instead of just flying it when that is exactly what they did with Falcon 9 V1.0 - uprated the engine and stretched the overall vehicle.

@eager_space This is actually a very well written document. Which is incredibly uncommon for manual, in my experience. It talks about lessons learned, trade-offs, best practices, etc. Most manuals are half full of text like "WARNING: battery may produce voltage."
None of your damn business
@peterrhague You people with the constant whining about government surveillance and bureaucratic oversight. What the fuck are you people doing in your daily lives that you feel such overwhelming pressure on your freedom from the governments?
@Pottertesla @eager_space @NASASpaceflight The patina the falcon 9 develops landing over and over again, making it look like something out of star wars, gives it character. This little skid mark makes it look like it shit its pants.
@eager_space @Rainmaker1973 > And what if it's windy? Even with conventional gear, you need very low wind to spray certain (expensive and/or dangerous) chemicals anyway, so there's that.
@eager_space @Rainmaker1973 That's the least of their worries :) *picks up blow dart gun*
@eager_space boeing decided to reuse that material from the previous flight of the starliner. @NASASpaceflight asked this question in q&a boeing replied that they thought of painting it but decided not to because "it gives it character".
This is not great for Artemis II happening in September 2025.

Government doesn’t fund SpaceX, they offer contracts and SpaceX consistently offers the best pricing, launch availability, and reliability. SpaceX is textbook natural monopoly because every other launch company was so focused on thinking what they were trying to do was impossible
@HOUSTANI2033 At this point the goverment shouldnt be funding spacex. SpaceX should be profitable with starlink and thats not even including all the falcon9 rideshares and Commerical missions. We need the funding to go to smaller launchers so SpaceX doesent have monopoly
It’s actually weird how cheap wind turbine blades are. They’re about $10/kg, compared to around $1000/kg for an airplane. The “idiot index” is low. They’re made with VARTM (Vacuum Assisted Resin Transfer Molding) instead of AFP and autoclaves. They use fiberglass mostly.
@eager_space I hope all goes well, but I have 0 excitement for this mission. It's gotten so bad that a a friend of mine forgot Starliner existed...
