Note that while the cultures were outside the Space Station, they were in containers simulating the conditions of Mars, so it doesn't seem like they were in the vacuum of Space itself, unless I've missed something in the article?
- seabass-labrax 3y agoI think you're right: the atmosphere inside the container was artificial and intended to be equivalent to the atmosphere on Mars, with natural light from the Sun allowed to pass into the container through filters which also emulated the conditions on Mars.
- dotancohen 3y agoIf I'm not mistaken Mars' atmospheric is pressure is less than 1% of the Earth's atmospheric pressure. That is a lot closer to a vacuum than it is to Earth conditions.
- hannasanarion 3y agomore like 4%, but yeah.
- JumpCrisscross 3y ago> Mars' atmospheric is pressure is less than 1% of the Earth's atmospheric pressure 0.0060 atm (0.6%), to be exact [1]. [1] https://en.wikipedia.org/wiki/Atmosphere_of_Mars https://en.wikipedia.org/wiki/Atmosphere_of_Mars
- KronisLV 3y agoFollowing that link, I stumbled upon these two: https://en.wikipedia.org/wiki/Atmospheric_escape https://en.wikipedia.org/wiki/Atmospheric_escape https://en.wikipedia.org/wiki/Future_of_Earth https://en.wikipedia.org/wiki/Future_of_Earth What an interesting, but harrowing existence to be a part of. I don't expect humanity to last that long, but even if we did, then those would be quite the obstacles.
- cyberlurker 3y agoI did not know in 600 million years trees would basically go extinct. Even if it is an incredibly far away time, I wonder what the gradual process will be.
- baxtr 3y agoWhat a depressing thought even if it’s still far away. Life itself started about 3.5 bn years ago. So we’re well beyond the half-time of life on this planet.
- stareatgoats 3y agoInteresting research, but the future has a nasty tendency to deviate from our expectations. The further out, the riskier the assertions.
- seabass-labrax 3y agoIndeed; one of the things I like best about the Ingenuity helicopter (sadly decommissioned only this week) is that it flew at a pressure that, were it on Earth rather than Mars, would be equivalent to twice as high as Concorde's cruising altitude!
