that coWoulduld shine on mars be able to heat it up alot faster then?

Question

building one right next to it. Basicaly what im asking is if you wanted to terraform mars by heating up the planet wouldnt it make more sense to build a mirror/lens closer to the sun then further away from it. Same could go for if you wanted to do the same for the earth if you had a way to use the energy of course. Maybe by putting something that could absorb and store energy near the earth and have the reflecting mirror/lens send light energy to it. :)

Wouldnt heating up mars itself make its atmosphere expand a lil in itself? But you do have a good point so basicaly all we would need is a way to put life on mars that can turn sunlight into air ect... I guess the easyest way to do that is by sending a lil bacteria factory of some sort there and putting water/light/air into its system and letting it spew out any extra stuff. It could use the ground of mars as a food sorce for the bacteria I would guess. This is probably a day or two away from what we currently have technologicaly capable tho but its a good thought I think maybe im wrong tho.

Answer 1

Heating isn't really the problem here. The real issue is the capability of Mars to *keep* the heat which the sun provides.

The atmosphere of Mars is about 100 times thinner than the atmosphere of Earth- therefore, all of the heat which reaches the planet is not kept very long.

Answer 2

That would take a lot of time though, to create a whole atmosphere. Think of the hole in ours. And i don't know whether the gravity on mars is similar. Does atmosphere need gravity to remain?. The earth version sounds a good idea. But wouldn't it become a weapon too though if controlled by radio.

You seem to have lost your mind.
