Is it possible to start 'terraforming' venus, by engeneering plant cells to float around in the upper atmosphere and convert CO2 into O2 over millions of years to bring down temperatures? Obviously they would need Genetic Engineering to survive the acidic upper atmosphere.
no water on Venus
barely a magnetosphere
A venus day is almost half an Earth year.
crust is thin and unstable
no moon, no tidal forces

That's a damn shame, all that land. Sigh.

We'll get to it, there are much easier places in the solar system to terraform.
>>7847194
In all fairness there is no place in the solar system that is a good candidate for terraforming.

Mars, but the best you can hope for is a something where it is like living on top of Mt Everest.
Building O'neil Cylinder Colonies at Lagrange points is a better use of time and resources.

Why not just put up a dome?

Long term effects of low gravity are unknown, we know near zero gravity is very bad for us.

the only reason to live on Mars long term is mining.
If you just need space to put people into an urban environment. Then O'Neil Cylinders are better.
Venus is perfect as a future planet for refugees

no.
you need to harness much more energy than you can in nuclear weapons. Take a dwarf planet like Makemake or Ceres and change its orbit to crash into Venus at the right angle and velocity. So that they both reform into a planet and moon system. Then pray it is spinning and forms a magnetosphere. Then you can start crashing water ice asteroids and comets into it.
This is also going to take millions of years.
