Perclorates on Mars

According to the above Yahoo article there are perclorates in the soil of Mars. If these didn't come from rockets associated with the robot(s) landing there then it gives one pause for thought. Did the perclorates come from our ancestors who had to leave Mars because of too much space travel (rocket propelled) polluting the soil with perclorates there and making it uninhabitable on the surface? Could we be making the same mistakes in regard to perclorates here on earth now?

It is very possible that the Asteroid Belt that the Soviet Probe found to be a planet blown up by a thermonuclear war could have been a war between Mars and the Asteroid belt planet. If so, are we descendants from Mars or the Asteroid belt planet that the Soviets discovered blown up from a surface thermonuclear war?

I have always thought it very strange that Western media never picked up on this research by the Soviet Union during the 1970s. The only reason I could figure out it wasn't picked up was Fundamentalist Christian thought and the panic it could have created in the Christian and Muslim world.

The fear this research created in the intelligentsia of the Soviet Union is one of the many divergent reasons the old Soviet Union collapsed. The scientifically educated people of the old Soviet Union didn't want earth to become an asteroid belt too!
