About Apollo 15’s lunar rover »

Mika McKinnon:

Apollo 15 was the first lunar landing mission to use a rover, allowing astronauts Jim Irwin and Dave Scott to explore farther from their landing site while still having time to conduct scientific research. Al Worden stayed in orbit, photographing a quarter of the moon’s surface during his three solitary days in a spacecraft in July 30 to August 2, 1971.

The lunar rover is one crazy peice of hardware.
