The Planetary Report
Humans On Other Worlds On the Cover: Humans have walked on the surface of only one world besides their own—the Moon. Someday we will return to the Moon, visiting our neighbouring world, Mars, and investigate asteroids that pass near Earth. In this issue we remember those first steps on the Moon and look forward to new journeys to other worlds.
