I'd personally be more interested in colonizing Venus. What would happen if we construct a large disc and put Venus in the shadow of it? It would cool over time and we could assess what to do then. Perhaps it still has a dyanmo in its center? Active plate tectonics? Water in unexpected places? Venus is very similar to Earth's size, much closer than Mars, and if we could cool it down and terraform it, a better Earth 2 than Mars.
Plus a version of such a disc might come in handy for Earth, if we cannot get warming under control.
- bilsbie 3y agoI’m thinking genetically engineer organisms to transform most of the co2 to a stable solid form. Maybe floating organisms that can live in the cooler upper atmosphere. Only catch is we’d need to provide a lot of water. I don’t think the atmosphere has much.
- javajosh 3y agoBuilding a disc to shadow venus is possible today. I don't think we currently have the ability to create the organisms you describe.
- SV_BubbleTime 3y ago>Building a disc to shadow venus is possible today. News to me. Just ignoring all the reasons this seems unlikely. Wouldn’t it be constantly pushed away from the sun towards Venus?
- cgriswald 3y agoI read a paper (that I can't seem to find now) that suggested putting such a sunblock up to freeze out all the CO2, then covering the CO2 with 'tarps' and putting the oceans on top of the tarps to lock all the CO2 in place.
- Kostic 3y agoBulletproof but not a vulcanoproof solution.
- Kostic 3y agoKurzgesagt had a nice video about that[0] (and the Mars terraforming as well[1]). [0] https://m.youtube.com/watch?v=G-WO-z-QuWI https://m.youtube.com/watch?v=G-WO-z-QuWI [1] https://m.youtube.com/watch?v=HpcTJW4ur54 https://m.youtube.com/watch?v=HpcTJW4ur54
