Mars Rock

I've heard of a theory which I believe was in Discover magazine which
explained how Mars lost a thick atmosphere which could've allowed the liquid
water to form which carved out all the canyons on the planet. They said a
asteroid slammed into Mars and shot debris along with a large chunk of the
atmosphere out into space. Could this be the same impact that caused that
rock containing the fossils to be shot into space and land on Earth? Am I
mistaken or have people simply not put two and two together yet.
