Apollo 15 Stand-Up EVA

Apollo 15 landed on the Moon at 5:16 p.m. Houston time (22:16 UTC) on July 30, 1971. Two hours later, Commander Dave Scott and Lunar Module Pilot Jim Irwin depressurized the cabin of the Lunar Module and opened the top hatch. Scott then stood on the ascent engine cover, poked his head through the hatch, and for the next 25 minutes described and photographed the terrain of their landing site in the Hadley-Apennine region. This was the stand-up extravehicular activity (SEVA), an opportunity to quickly survey and report on the lunar landscape they'd be exploring over the next three days.

For the 50th anniversary of the Apollo 15 mission, the video presented here uses elevation maps and images from Lunar Reconnaissance Orbiter (LRO) to visualize the Hadley-Apennine terrain. The camera pans across the Apennine mountains and Hadley Rille that border the region, then flies low over the surface to features that were explored up-close by the astronauts. The visuals are matched to audio excerpts of Commander Scott's descriptions during the SEVA.

Because of its unique timing, Apollo 15 was the only mission to include a stand-up EVA. It was also the first of three missions to bring a lunar rover, an electric Moon car that allowed the astronauts to travel a total of 17 miles (28 km) and collect 170 pounds (77 kg) of samples.
