The environment in the Venusian atmosphere isn't actually particularly extreme high up. At 50km up you could walk around outside your vessel in shorts and a breathing mask. I'ts just CO2 instead of N2/O2 and has about 1/10th the amount of water vapor as on Earth. And a little acid but well within industrial safety limits.
- Symmetry 6y agoTo be clear, you don't want to breath the acid for more than 10 minutes but we're stipulating a breathing mask here.
- ta8908695 6y agoFrom the press releases today, the clouds of Venus are upwards of 80% sulfuric acid, and on earth the highest concentration of acid we've observed things living in is 5%. All of the expert testimony I heard described Venus as far to acidic for any life on Earth [0] [0]: https://www.youtube.com/watch?v=y1u-jlf_Olo https://www.youtube.com/watch?v=y1u-jlf_Olo
- Symmetry 6y agoLooking more into it, the problem seems to be that while the absolute amount of acid isn't that high the ratio of H2SO4 to H2O is super high and there just isn't very much of either in the Venus clouds. The absolute amount matters a lot if you're just stepping outside for a bit but ratio is the only important thing for theoretical floating bacteria since they have to get their working fluid somehow.
