描述Dune crater Station 4 boulders AS15-87-11779HR.jpg
English: Basalt boulders on south rim of Dune crater, Hadley-Apennine, the moon. Taken at Geology Station 4 on the Apollo 15 mission. This is cropped to mimic Figure 3-23 of the Apollo 15 Preliminary Science Report (NASA SP-289, 1972), which has the following caption:
Much of the activity at station 4 was devoted to the boulders shown in this photograph. These boulders are basalts and represent material excavated during the formation of Dune Crater. The crew reported that vesicles were abundant in the boulders at this location and that some vesicles were as large as 9 cm in diameter. The abundance and size of the vesicles in these boulders suggest that this basaltic material cooled on or very near the lunar surface (AS15-87-11779).
