Two Harvard scientists have found that the dark areas of Mars rise six to nine miles above the brighter deserts, contradicting the standard theory that Mars is an almost smooth planet.
In the traditional view, the dark areas of Mars are considered lowlands, with bright sectors a mere mile or so higher. But Carl E. Sagan, assistant professor of Astronomy, and James B.

Some of the space fledglings may be assigned to a NASA orbiting laboratory, which is planned for flights of as long as 30 to 90 days sometime in the 1970s. However, the group's 18 to 24 months of exhaustive training will be principally aimed at following up the...
