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.

May be wrong about what? that mars is a leaky bucket.
Even if you could raise the temp on mars, which you cannot, to get liquid water, the water would quickly evaporate into space.
