Group Plans to Bring Martian Sample to Earth
sm62704 (mcgrew) writes "New Scientist has a story about IMARS (the International Mars Architecture for Return Samples) planning to bring samples of Martian soil to earth. The robotic mission would be a needed precursor to manned trips to the red planet. Also, international cooperation is necessary since the US has already nixed bankrolling manned Mars missions."
With about 0.35g, they may just send a Mars Rover with a mechanical arm and also send pieces to build a catapult. In six months or so, the rover builds the catapult and uses it to throw a piece of ground back.
The only problem could be the rover exceeding his expected lifetime thirteen times and burying us in Mars pieces.
