...probably turn out to be the best. During their record 22 hours outside their moonship, Cernan and Schmitt collected some 250 lbs. of lunar rocks, more than any of the ten moonwalkers before them. They set up the moon's fifth scientific station and drove their battery-powered rover across 22.5 miles of the cratered valley. They took more than 2,000 photographs, and turned up what may well be the first positive evidence of relatively recent volcanic activity on the moon. Said Schmitt, the first scientist to walk the moon: "This valley has seen mankind complete his first...
...that he regarded the stark, rock-littered valley as his special turf. "A geologist's paradise, if I've ever seen one," said the Harvard-trained scientist as he and Cernan began their preliminary chores: familiarizing themselves with the terrain, photographing the area and, finally, maneuvering the rover out of its berth in the side of the lunar module. Then, after a fast test spin by Cernan ("Hallelujah, Houston, Challenger's baby is on the road"), the moon car was positioned so that the remote-controlled color television camera mounted on the front end of the vehicle...
Cernan also had reason to be embarrassed. With one swing of his geological hammer, he accidentally clobbered the $13,000,000 moon car, knocking off part of one of its rear fiberglass fenders, which act as shields against the spray of dust churned up by the rover's wire mesh wheels. Cernan tried to reattach the section of fender with gaffer tape. But because of the everpresent, clinging fine-grained lunar dust, it would not stick. As precious minutes ticked away. Mission Control suggested that the astronauts abandon the fender repair work and get on with the more important...
After buckling themselves into the rover the astronauts will continue their first EVA by driving southeast for about one mile to the edge of a 2,000-ft.-wide crater called Emory. It is here that Schmitt hopes to recover fine-grained dark material, called pyroclastics (literally, broken up by fire), which may be a sign of relatively recent volcanic eruptions. If Schmitt's trained eye happens to spot any interesting material between scheduled stops, he will be able to pick it up without leaving his seat in the rover; at hand will be an extension pole with...
...will be ignited by signals from earth after the astronauts leave the moon. Their blasts-which will register on the ALSEP'S geophones and thus provide data about the moon's interior-may well be seen on earth through the remote-controlled TV camera atop the abandoned rover...
