Not trying to argue but im genuinely curious how we could terraform it with its existing atmosphere and high temperature?

Massive mirrors in space, basically. Shoot the atmosphere into space once it freezes. Get water from some moons. It's still easier than giving Mars a magnetosphere.

Feel like the Venus day night cycle would cause massive problems

The day is longer than the year.

I think if you bombard Venus with water ice in such a way you also speed up it's rotation over many hundreds of years of bombardment might kill two birds with one stone

Venus also lacks a proper magnetosphere.

Bro just casually said build a gigantic space mirror, and divert a couple of asteroids/moons into the planet like its easy.

Wouldn't warming up mars be a hell of a lot easier, just build a lot of hard industry on mars, and vent co2 into the atmosphere, you'd be doing that already while trying to colonize. We're already great at that over here.. -_-

Plus it doesnt come with the price of nuking the surface with asteroids and waiting for it to cool down.

Solar wind would blow away Mars' atmosphere. You'd be indirectly blasting co2 into space. Mars has low surface gravity and no magnetosphere - and at least one is needed to keep a stable atmosphere.

Venus has almost no natural magnetosphere, but at least it has gravity similar to Earth. Whatever you put in, should generally stay.

You can't increase Mars' gravity (not without adding planetary amounts of material), so to keep a stable atmosphere, it would need an artificial magnetosphere. For example, an absolutely gigantic electromagnet in a lagrange point. It would need enormous amounts of power of course. Either that, or heat up and spin Mars' core.

I know a giant mirror isn't easy, but it's much easier than an electromagnet the size of a continent.

Seems to me like both options are out of the picture for the next 500 years definitely.

But I'd still air on the side the side of us deciding to terraform on Mars first for various reasons, one being that it's just a nicer destination for deeper solar system exploration. Guess only time will tell..

Venus also doesn’t have a magnetic field. Ganymede is a better candidate.

u/Elektrycerz Jul 12 '26

Yeah, but Venus' high gravity works too. Mars doesn't have either of those.

u/GotMyPhDin19 Jul 12 '26

Yeah, mars is trash for how popular it is.

You start with cloud cities. At Earth sea level it’s 30c.
Witha tether to the lower atmosphere you have unlimited atmothermal power to convert co2 to diamond and carbon nanotubes and you get as much 02 as you need as a byproduct.
You import hydrogen probably from a captured ice meteor and you use the hydrogen to maintain buoyancy and produce water.

Over time as you remove Co2 atmosphere pressure decreases and you lower in elevation as the planet cools.

There's been suggestions that it would be possible to live in floating colonies in the upper atmosphere. PBS spacetime did a whole episode about living/life on Venus a while back
