Four NASA astronauts have emerged from a 3D-printed habitat in Houston after spending 378 days cut off from the outside world.
The crew exited isolation on Saturday after completing a NASA exercise intended to prepare astronauts for a possible journey to Mars. They had lived inside the 1,700-square-foot (158-square-meter) structure at the US space agency’s Johnson Space Center since Oct. 19, 2025.
Their tasks during the simulated mission included growing crops in simulated Martian soil and communicating with NASA officials under delays recreating those inherent in interplanetary communications.



I mean, yeah? Seems fairly obvious I’m basing things on what I think it would be like for me…was that supposed to be a gotcha or something?
I agree though. And especially astronauts. Maybe that’s the point though…I’m not self disciplined enough to be an astronaut.
Fair to say that 4 randos would struggle? Can we agree on that?
Maybe, maybe not.
But these aren’t “randos” that we are talking about.
Did you miss the part where I said exactly that and agreed with you?
