Fact sheet
15298 is a brown glass matrix breccia, broadly similar to 15295 and 15299 and numerous other breccias returned from this site. The high agglutinate content shows that this breccia, and the others like it, was formed from compressed lunar soil. Rotation 1 shows a pale green glass bead and a fragment of plagioclase feldspar (possibly lunar highlands material). Rotation 2 shows a large breccia-in-breccia (impact melt)fragment and a partially devitrified colourless glass fragment.
The sample weighed 1731 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.
