15027 (7) Regolith Breccia
15027 and 15028 are glass-coated breccias found together near the lunar module. Pale green/brown volcanic glass, some fragmental and some forming subrounded or spherical masses are most obvious in thin section (see rotation 2). Many mineral fragments and a few basaltic clasts are also present. Veinlets of impact melt criss-cross the sample although in our thin section they are lacking. Troilite and metallic iron are also present in accessory amounts.
The sample weighed 51 grams before analysis. It 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.
