Apollo program was designed to land humans on the Moon and bring them safely
back to Earth. Six of the missions (Apollos 11, 12, 14, 15, 16, and 17)
achieved this goal. Apollos 7 and 9 were Earth orbiting missions to test
the Command and Lunar Modules, and did not return lunar data. Apollos 8
and 10 tested various components while orbiting the Moon, and returned photography
of the lunar surface. Apollo 13 did not land on the Moon due to a malfunction,
but also returned photographs. The six missions that landed on the Moon
returned a wealth of scientific data and almost 400 kilograms of lunar samples.
Experiments included soil mechanics, meteoroids, seismic, heat flow, lunar
ranging, magnetic fields, and solar wind experiments.
All tracks, except track 5, are named after the landing sites of all manned
