I absolutely love hearing stories from astronauts about how quickly they adapt to microgravity and how easy it is to forget when they come back. Things like stories of them suddenly letting go of stuff they are holding on earth and expecting it to float there, or reaching out to grab on to a wall to stop themselves while walking down a hallway.

I've heard a couple of similar stories from people who spend a lot of time in VR and forget that the rules don't transfer back. One guy smacked his head into the fridge door trying to look inside it because he forgot that he would actually collide with the door.

Now that you mention that i've absolutely felt that from VR! In my case it was because I got so used to the ability to point at something, "grab" it in the distance, then float it to my hand, that I tried to do it at one point to a can of soda in real life and felt really dumb!

Mars is more livable than the moon because it has atmospheric CO2, (more) water, and a better mineral story. The goal of a Moon base is not living there, it's building from a place near to Earth but outside the gravity well. Martian atmosphere and water are a pie in the sky. If we're unable to build a base in the Moon, how are we supposed to do it in Mars? If we can do it in the Moon, it would be incredibly useful fo…

Or, as I always say when this comes up, start with a base on the top of Mt Everest. Much more similar to Mars, and definitely cheaper to try. With all the challenges of no breathable air, storms, inhospitable rocky terrain, bleak environment.

If this seems ridiculous or impossible, then that's the state of our Mars colony ambitions as well.

Have there been precious studies that look at generic changes in astronauts? This article is great but it feels like everyone mentioned in it is making a lot of statements on an extremely limited sample size.

Yeah, so far there were just estimations. Even this is still in a wayI mean my gf's father has a twin and they were mirror image of each other but then in less than 5 years both became so different that you can hardly even tell that they are related in any way. If there will be few more twins to repeat this project then a more generic result could be gathered.

There is already an undersea base for training astronauts for the ISS. There is also the ISS, which is already a significantly more challenging environment than Everest. Although it would be nice to have scientific outposts in all of these places, one must bear in mind that these things are very expensive, so the cost/benefit of the scientific value has to be weighed carefully. The cheapest option is not always the best value.

A lunar space station called LOP-G (lunar orbital platform gateway) is presently planned, and although it is a "smaller step" it is being widely attacked for not being useful.

Maybe the reality is that all the science fiction stories have got it wrong all these times: that we have to genetically engineer different humans to traverse interplanetary (and in the far future, interstellar) distances and to live in alien worlds, so that we have less in common with them, physiologically, than we have with, say, the Cro Magnons.

For interstellar distances I'd go with Greg Egan's Diaspora and Accelerando by Charlie Stross and assume that interstellar distances could only be achieved with uploaded minds - bags of meat and fluid being far too big, slow and delicate for the energies and distances involved.

I heavily played GTA: Vice City during the time I learned how to drive. After I got my driver's licence, I remember one instance where I clearly noticed how my brain drifted into GTA mode while I was driving through town. I had to actively remember myself that this is a real environment and that I cannot just drive over the street lamp post without anything happening. I talked to a classmate about this and he had had…

I'm surprised you developed connections between the two - I've been playing computer games a longtime, and find the cognitive load and muscle memory of real world activities to be markedly different than something like GTA, but I only was playing Need for Speed 2 as I learned to drive, so maybe that didn't quite meet the realism requirements, not to say Vice City is some VR masterpiece, but it was credible in its day…

if you drive down a straight road in a quiet town at constant speed and don't have to shift, I don't think the cognitive load is much bigger than driving around in GTA. After all, you are basically just scanning the environment in front of you for obstacles. It also seems to go both ways: when I returned to playing GTA after a few months, I was driving much more carefully in the game.

I guess outline.com doesn't work on NYT any more. Copy/paste here?

Do what you got to do, but I'd like to take a moment to say I signed up for an online subscription. Journalism is important and I'm ok with a couple bucks a month to support it.

I'm really not looking forwards to VR driving games, then.

For real, though, apparently there was a notable increase in young driver deaths when all the kids who grew up on Gran Turismo started driving for real. A whole generation had been trained on some level that crashing had no serious consequences.

Now I remember my Need For Speed strategy of holding down the accelerator and bouncing off walls to go around corners.
