...probes, Mars 2 and 3. But some U.S. observers have concluded from the size of the spacecraft-which weighed about 8,000 Ibs. more at lift-off than their American counterpart-that the Russians may be attempting an actual touchdown on the Martian surface, perhaps landing an automated Mars rover similar to their highly successful Lunokhod I, which roamed the moon for ten months. (The first U.S. Mars landing mission will not be launched until...

...Astronauts Dave Scott and Jim Irwin. After driving past a group of craters called the South Cluster, they made their way up a 7° slope toward the mountainous Apennine Front, and approached an imposing 12,000-ft. peak called Hadley Delta. The astronauts stepped out of the rover and began to select rocks, describing each to the fascinated geologists back in the science support room in Houston. One rock looked like "green cheese"-until Scott raised his gold-tinted visor and saw that it was really gray...
After returning to the rover, Astronauts Scott and Irwin drove to Hadley Rille, a long, winding, 1,200-ft.-deep canyon whose origin has long been the subject of scientific debate. While the rover's remote-controlled TV camera followed them with its big-brotherly eye, the astronauts walked slowly down the rille's gently sloping near side. On the almost vertical far wall, they spotted at least two major layers of material. Even more interesting to the scientists in Houston was the astronauts' report that the second major layer contained at least ten subordinate layers...
...little later, Scott was on his knees again, intentionally. Using a hammer, he chipped a large chunk off a big, lava-like boulder sitting on the rille's ledge. Then he tucked the piece under his arm like a football and galloped enthusiastically back to the rover. Scientists in Houston shared Scott's exuberance. He had apparently snared a valuable chunk of the moon's bedrock...
