Then, move the MegaMaid into an orbit around Mars and go from suck to blow. Venus has too much atmosphere, Mars has too little. Win Win.

  It wouldn't do Mars any good. Lacking a magnetosphere, any atmosphere you add will get stripped away by the Sun.

    I’ve read that a large asteroid could be positioned at a particular Mars L point and it would protect the planets atmosphere from being stripped by the sun.

      I've read something similar, but I believe it has to be an asteroid with a magnetic field, whether permanent or electromagnet.

    The atmosphere will be stripped away over a time period of millions of years though.

    The estimate I heard is it would take 100,000 years for the atmosphere to be stripped off. That’s a long long time.
