Fact sheet
15325 is a regolith breccia collected as part of a large soil (15300) and rake sample (15310). 15306, 15315, 15324 and 15330 are additional large soil breccias from the same rake sample, and there are many smaller fragments from the same sample. They all contain pale green glass beads. Our thin section contains many glass fragments with colourless, orange and mustard yellow beads also being present. Basalt and breccia-in-breccia fragments occur commonly. Rotation 1 shows a glass-rich area which between crossed polars is almost entirely isotropic (apart from a pyroxene fragment). Rotation 2 shows an unusual brown rimmed, partially devitrified glass bead and a small basalt clast.
The sample weighed 57.8 grams before analysis and has not been dated.

The Apollo 15 landing site was in the Apennine Highlands, and close to Hadley Rille — a long, narrow winding valley. Approximately 76 kg of lunar material, including soil, rock, core-tube and deep-core samples, were returned to Earth.
This mission was the first flight of the Lunar Roving Vehicle which allowed the astronauts to venture further from the Lunar Module than in previous missions. During three periods of extravehicular activity, or EVA, on July 31st, and August 1st and 2nd, Scott and Irwin completed a record 18 hours, 37 minutes of exploration, travelling 17.5 miles, in the first car that humans had ever driven on the Moon.
Apollo 15 was launched on 26 July 1971.
