Orbital photo of the Hadley-Apennine site; Apollo 15 landing site is marked with a circle.
Hadley–Apennine is a region on the near side of Earth’s Moon that served as the landing site for the American Apollo 15 mission, the fourth manned landing on the Moon and the first of the “J-missions”, in July 1971. The site is located on the eastern edge of Mare Imbrium on a lava plain known as Palus Putredinis. Hadley-Apennine is bordered by the Montes Apenninus (often referred to as “Apennine Front”), a mountain range, and Hadley Rille, a meandering channel, on the east and west, respectively.
Data obtained from the composition of soil samples collected on Apollo 15 show that most (about 90%) of the samples from the Apennine Front are brown-glass breccias, and approximately 60–70% obtained from the mare surface are basalt. Although the basalts seem to vary in their texture, their ages appear to be approximately the same. Most of the samples obtained on the Apennine Front are KREEP (potassium, rare-earth elements, phosphorus) materials, anorthosites, recrystallized norite, or recrystallized breccia.
What’s that little figure in front of the plaque?
