If 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!
