Did Mars Suffer From A Natural Nuclear Explosion?

Mars is the bomb. Or rather, may have been bombed. But not by rogue Martians or those weenusmunchers from Venus. No, it was totally natural. This explosion wiped out all life on the planet and left it a wasteland of red sand. At least, according to one theory:
“The Martian surface is covered with a thin layer of radioactive substances including uranium, thorium and radioactive potassium — and this pattern radiates from a hot spot [on Mars],” Brandenburg told FoxNews.com.
“A nuclear explosion could have sent debris all around the planet,” he said. “Maps of gamma rays on Mars show a big red spot that seems like a radiating debris pattern … on the opposite side of the planet there is another red spot.”
According to Brandenburg, the natural explosion, the equivalent of 1 million one-megaton hydrogen bombs, occurred in the northern Mare Acidalium region of Mars where there is a heavy concentration of radioactivity.
Some are intrigued by the theory but others believe the only way to prove it would be to send a mission to Mars, which are resources better spent elsewhere, like trying to find other intelligent life.
Or we could just invent a time machine and hit it with a nuclear warhead. Problem solved.
