How much to terraform Mars with nukes?

terraforming is a meme, mars core is dead so it's impossible

A question here. Why does venus lack magnetic field when turds like mercury and even ganymede do? Is the high crust temperature fucking with the whole dynamo thing?

>How much to terraform Mars without magnetic fields?
It would take millions of years for Solar wind to destroy the atmosphere.

>MUH FLOATING CITIES
Not only would terraforming Venus be far FAR harder than doing it to pretty much any other planetary body in the solar system but even getting to venus is harder than it is to get to other places since you have to have an enormous amount of delta v to decelerate sunward.

>Is the high crust temperature fucking with the whole dynamo thing?
Yeah most likely, no/little convection.
