Mars lost its magnetosphere 4 billion years ago, so the solar wind interacts directly with the Martian ionosphere, keeping the atmosphere thinner than it would otherwise be by stripping away atoms from the outer layer. Both Mars Global Surveyor and Mars Express have detected these ionised atmospheric particles trailing off into space behind Mars.

You may be wrong about that - and I think you are - Craig makes an excellent point.
Nevertheless, I think I may agree that it is slightly futile to bombard mars with comets in hopes of habitation. I fail to see how putting ice on an iceberg will help you grow an apple tree. Mars is frozen. It will remain so until it has an atmosphere and quite a substantial atmosphere at that. There's probably a clever way to overcome that problem, I just can't think of it.
