The research of John Brandenburg suggests that Mars was once teeming with life, cut short by the detonation of two massive nuclear weapons. As a nuclear scientist, he is keenly aware of the effects of nuclear explosions and has discovered such tell-tale signs on Mars.

He suggests that the greatest memorial we can erect for the lost Martian civilizations is to resurrect the biosphere and bring life back to Mars.
