If I understand correctly, they reentered nose-first because the service module was acting like a big parachute behind them. (Lots of drag.) No ability to keep the entry shallow using aerodynamic lift, hence the steep (ballistic) entry, over 8G. And because it was decelerating nose first, they were hanging forward against their seatbelts instead of being pushed against their backs. OUCH !!!

@elonmusk @gailalfaratx @yunta_tsai It’s crazy how many lives have been affected by fsd. The trouble is most folks will never know. It’ll just be another Tuesday for them rather than a day when their lives changed for the worse. It’s tough to prove a negative.

A lot of AI engineers have spent their most productive years chasing benchmarks instead of solving useful cases they can relate to. If the car fails to take me home, then I simply fail at my job and can’t go home. That’s it.

@Astro_Clay This is so cool: I asked Grok about the location of your reddish-brown image. It looked at the photo, recognised it as “Roter Kamm Crater” and even gave a Google Maps link. Looks very similar to your hand-held photo from orbit! google.com/maps/@-27.7667…

A few people in the comments have mentioned paragliding. Powered paragliding, where you strap a paramotor on your back or use a trike if you don’t like running, is probably the cheapest form of powered aviation on the planet. It’s quite weather/wind dependent, but fun-wise, compares favorably with my C150 days. Flying low and slow is where they excel… like a sci-fi jetpack. A 737 captain friend who owns a helicopter and a Beechcraft Bonanza, says his paramotor is the most fun of them all! I understand that it’s a different world from GA, into which you’ve invested a lot of time/money/effort. But just throwin’ it out there! Photo of me around 2008.

I’m obsessed with VTOL aircraft, but always nervous flying in helicopters because I’m acutely aware of the MANY potential failure points, each with FATAL consequences: So I’m very excited about the potential for these eVTOLs. Control via differential RPM over a distributed lift system, with associated redundancy… LOVE IT.

Even small content creators can afford to buy jets, but the cost to operate these makes them dubious deals.

@JasonGibsonMath @Astro_Clay That’s a good point. I actually was about to say the same thing when I saw your post. The movie “Interstellar” portrays that isolation well. Delayed video clips from loved ones are like digital postcards… nothing like live interaction.

Thanks for sharing your experience! I think it’s really interesting to contemplate multi year trips to other planets. I think it’s even going to be harder because real-time communications with family is going to be impossible without significant delay. The human element here is going to be the most difficult problem to solve I think.

I have often noted, in many forums, that the biggest psychological challenge I faced during my long-duration spaceflight was being separated from my wife and young children. It was tough—being so “far away” (distance-wise, I was but 240 miles away) from family hits hard, especially when daily routines on Earth keep moving forward without you. I often compared a months-long mission to the flow of a football game, as the game has a natural rhythm and momentum that mirrors the ups and downs of orbit. During the “first quarter” after all of the pre-game warm-up, you, the team (crew), and the crowd are into it and everyone is excited. Then comes the second quarter. Things calm down a little bit and everyone gets into a rhythm/flow until halftime. Then, at the beginning of the third quarter, all bets are off and it can become more chaotic as unexpected issues pop up, systems act up, or workloads spike. It may take some time to lock back in to your previously-found rhythm. The fourth quarter is much more intense. Everyone is fighting for their desired outcome. Tensions mount, things become more critical, and tasks must be accomplished before you return home (the game ends). It’s a good analogy to my long spaceflight. During my five-month expedition, milestone tasks and events, such as spacewalks or piloting the robotic arm, were spread out over the months, giving me new things to accommodate my focus and look forward to. It provided a sense of achievement, and helped to reset my mental clock.

@zanehengsperger And so I went to Cernan and astronauts from all of the Apollo missions and got their signatures of tribute to SpaceX. It was a birthday gift to Elon and hangs the entryway at SpaceX HQ. Armstrong made 60 Minutes publish a retraction too. Details: steve.blog/2012/07/11/the…

when spacex was getting started, the first and last men to walk on the moon testified before congress against it. gene cernan told congress commercial space companies "do not yet know what they don't know." he said the boeings and lockheed martins were "the folks who have been working on everything we've done for the last 50 years. they know how it can be done." neil armstrong said he was "not confident" the newcomers could achieve their goals. together with jim lovell they warned it would put america on "a long downward slide to mediocrity." spacex now launches more rockets than every country on earth combined. the experts will always tell you it can't be done. build it anyway!

It’s mind-blowing to think that this system will let you take measurements at centimeter-level accuracy, without relying on base stations. As a user of RTK GPS for drone 3D mapping, I’m at the mercy of the availability of nearby base stations. (For those unfamiliar, the base station knows its position accurately, so the system says to your unit “Hey, the GPS is giving a wrong position by exactly this amount, so adjust your measurement accordingly!”) Clever system, but what a breakthrough to bypass the need for bases altogether!

Today we opened our satellite manufacturing facility—alongside @RepKevinMullin and partners across the space and tech ecosystem. From this facility, we’ll produce and deploy a constellation of 250+ American-made satellites over the next five years—at a total cost lower than a single traditional GPS satellite on orbit today.

@Astro_Clay Actually, that’s an interesting question: I wonder how loud was it in the shuttle cabin, and what kind of frequency? I imagine there would be a lot of white noise, predominantly at the low end. Probably a lot of it would come from the vibrating hull itself.

@DJSnM It warms my heart seeing it being cherished and preserved like this. Very different to what happened to Buran, abandoned in a hangar in Kazakhstan that collapsed and destroyed it.

I know a lot of space fans are still on the space coast and planning to go to KSC Visitors center, which is absolutely worth your time. And as 'Mr Manley' I just want to make it perfectly clear that it's perfectly acceptable to get teary eyed when visiting Atlantis. (but if you're really sensitive about your masculinity or, just don't have time for the big reveal you can always enter via the gift shop to soften the impact)
