The Standup

Scott and Irwin then began going through their check list in preparation for the first - and last - EVA of its kind during the Apollo missions. The two astronauts would don their helmets and gloves, pressurize their suits, and then Scott would open the overhead hatch and remove the docking drogue assembly to perform a Standup EVA (SEVA). This was essentially a site survey to see whether the area was strewn with boulders or was clear enough to employ the Lunar Roving Vehicle.

''One of the reasons for the standup EVA since we were working with the rover,'' Scott said during the interview, ''was that we had been told by the radar people that there were boulders - lots of boulders - at Hadley. Our photos of the area had a resolution only down to 20 meters, so in the photo, you couldn't really tell. So, one reason for the standup EVA was to check the trafficability of the area to see if we could drive the rover. If you are looking at two-, three- or four-foot boulders around, the rover isn't going to be much use. Fortunately, there were none.''

Another reason for the SEVA was to take photographs of the entire surrounding area of the Hadley landing site. Scott was encouraged by what he saw. While there were many small craters, the plain for as far as he could see was free of boulders of any size. As he took photographs with the Hasselblad camera and described the lunar terrain, he spoke in terms of a trained geologist. As he did so, he also dispelled preconceived notions of the Hadley region of the Moon. As previous Apollo missions had proved, and Apollo 15 was already proving, there was no substitute for manned exploration. He described Hadley Delta, he could see the Northern Complex of craters and the inner walls of Pluton Crater and he identified Icarus and Chain Craters. Scott could not see the edge of Hadley Rille but he could see its far side. After finishing the photography and his description of the region for a rapt audience back in Houston, Scott closed out the SEVA by replacing the docking drogue and closing the hatch. They re-pressurized the LM, removed and stowed their suits and broke out their food for their first meal on the Moon. That night the astronauts slept well, eager for the next day's activities.
