> now that we have SpaceX You don't have SpaceX. It's a private company. Soon you might not have NASA either. As part of his payment for supporting Trump, more and more of NASA and the Department of Defense will be handed to Musk for his profit. Oligarchs always expect to be paid.

Someone posted a scrollable web page depiction of Musk's worth a while back. The entire NASA budget is insanely small by comparison. To imagine it, I would guess he cares more about what's in his omelet than getting more money from that budget.

Musk is frustrated with government inefficiency, especially with regulatory processes. He has complained multiple times about the approval process for launches and returns.

One government agency, he said, at one point required them to do a study that estimated the chances of a re-entering rocket body impacting a gray whale in the event that it splashed down hard -- personally I agree, that is kind of ridiculous.

You need a huge group of people to even vaguely approach self sufficiency, or multiple generational advances in manufacturing. For example, if you are importing microchips, you are not self sufficient.

If I gave the impression that I thought we could go to Mars, I’m sorry, because I don’t think that realistic at all.

That is the impression I got, but upon re-reading your comment + context I see that I misjudged.

..However, what it looks like you said is that you think NASA wants the public to believe that going to mars is a solution to climate change? Am I reading that right? If so, what makes you say that? If this was SpaceX I might've agreed, but a lot of NASA's resources are spent monitoring the climate on earth to help us tackle climate change, and I can't recall any communication from NASA about how going to mars is a near-term solution to climate change.

If I'm misreading you again, I apologize.

Space Herpes. Definitely Space Herpes. I swear I can’t be the only one who has seen Ice Pirates (1984).

There are dozens of us! DOZENS!

Oh thank the gods… I was worried I was the only one with persistent nightmares about castration engines.

We already know that low-gravity causes all kinds of bone and muscle weakness and even messes with eyesight in a dramatic manner. The scary part is while the bones/muscles can be healed over time, the eyesight problems persist and appear to be irreversible. They have to solve this before trips to Mars will be possible, unless they are going to simulate gravity by constantly (slowly) accelerating half-way there and th…

A constant-acceleration flight profile would also be a lot faster for interplanetary travel, but is impractical for any known or currently plausible reaction engine: the rocket equation strikes again. Ion or Hall-effect thrusters require only electrical power and so can more or less continuously accelerate, but they produce far too little thrust to provide meaningful pseudogravity. Classically, the way to mitigate th…

It's really interesting/odd that spin gravity stations have not been tested out in practice yet. Everyone just wants to do zero G experiments on their station and nothing else.

I think the dual spacecraft with a long cable is really the only practical option, since you get far too much coriolis for it to be bearable otherwise. Remains to be seen if they can make it work with two spacex starships though.

Suni Williams who is still in orbit, has lost a lot of weight. I wonder if it's related to that. Trying to find a commonality. This quote was interesting, not sure exactly how true it is - "Due to changes in metabolism, astronauts consume twice as many calories as an ordinary person: just to maintain their current weight, it takes about 4 thousand calories per day. Williams, doctors suggest, will need about 5 thousan…

Wow really? This could be a huge market for rich people who need a beach body within 3 months. Ozempic + a vacation in space could be a game changer for them.

Lose weight while floating sedately...sounds good to me

This is exactly the kind of headline that would appear 20 minutes into a B-rate sci-fi movie. As we approach Act II, an intrepid young journalist rushes to the hospital to find out what’s really going on… But wait, who is in the black car trailing her?

Pretty much the opening plot to Stranger in A Strange Land

Astronauts have privacy too

Yes. That is absolutely true. The conflict of course is that the point of sending astronauts to space is to learn about the medical effects of the space environment on human bodies. Basically they are participating in a very expensive publicly funded medical trial. So the goals of that need to be balanced against their privacy. I’m not advocating that NASA should publish high resolution pictures of astronauts with pu…

It could be a medical condition entirely unrelated to their mission. If it's unrelated, the astronaut deserves their privacy. If spaceflight made their condition worse in some unexpected way, that should probably be made public. Maybe NASA is just waiting to confirm which option it is?
