Three essential pieces of equipment on any moon landing appear in this image.
The Lunar Rover, which has been likened to "a spacecraft on wheels," carried a
navigation computer, communication systems, tools, maps, and, of course,
astronauts. Though it traveled at a top speed of just seven mph, at each
bump the wire-wheeled vehicle (shown here with Lunar Module pilot Charles Duke)
took flight because of the moon's low gravity, which is but one-sixth that on
Earth. To the rover's right is the Lunar Module, giving a good sense of how
difficult it is to judge distances on the moon. To the rover's left, out in
the middle distance, stands a square, black object: the Apollo Lunar Surface
Experiments Package. One of the instruments in the ALSEP was a seismometer,
which recorded everything from meteor strikes to the crash landings of spent
Lunar Modules and Saturn boosters. The panorama was taken by Commander John Young.
