Hundreds of ships, planes, doctors and technicians stand by to rescue them from error.

Because the best prospects for life would almost certainly exist in the most humid areas, Astronomer Schorn suggests that the first landing be made at the edge of a receding polar cap, where the Martian soil should be as wet as it ever gets...
