It would probably throw up enough dust into orbit to prevent anything landing for the next 1000 years :(

- Retric 14y agoThe atmosphere is a little to thin to keep dust around for vary long.
- Jabbles 14y agoI said orbit.
- jonsen 14y agoYou can't throw a thing into orbit. Its trajectory will include the point where thrown.
- sageikosa 14y agoI had to think about this, but much of the dust will not shoot straight up like a column (with no tangential component), but will be shot sideways, conceivably with enough initial momentum to attain orbital speeds (which are lower on Mars than Earth), with less drag to hinder. Don't know if it would be 1000 years, but I'd guess it would coalesce into a ring like structure over time anyway.
- danielweber 14y agoGiven one single impulse from the surface, you will either land back on the planet; or, with enough force, totally escape the planet (called a hyperbolic orbit, I think, which doesn't actually orbit). Even amazing plans to build railguns on mountains to launch things to space requires some kind of secondary thrust to change into a new orbit that won't land back on the planet.
- sageikosa 14y agoA small but finite amount of dust could fall in the range of initially traveling at escape velocity but then slowed to orbital velocity by the scant atmospheric drag. But definitely not 1000 years of opaque orbital debris. Anyway, I would think atmospheric dust storms as the post-impact pressure wave cycles around the plant would make Mars more messy in the hypothetical aftermath than any orbital debris.

- maaku 14y agoThe Moon begs to differ.
- Retric 14y agoThe moon did not show up in earth after a collision, it destroyed the plant that was there, and then the earth and moon formed from the debris cloud. Anyway, orbital mechanics are complex, Mars has 2 moons and the sun plus the solar wind all of which clean up it's orbit which is why it's so clear in the first place. However, it would be possible for Mars to collect this as another Moon which would be vary cool. Or worst case it collides with one of the existing moons and then you get a lot of junk in orbit.
- Retric 14y agoWorst case it hit's one of the existing moons and you end up with a lot of crap in orbit. You would still be able to land easily, it would just make keeping satellites alive for long periods much harder, and significantly increase the amount of dangerous meteors that hit mars. However, if it hits the planet your home free.
