Apollo 14 mission. Astronaut Alan Shepard next to the boulder at Station B2. In the Apollo 14 Preliminary Science Report, this boulder is referred to as Big Rock. The upper surface is unusually flat and may represent a fracture surface. The rock is 0.6 meters high and about 1.5 meters long. We can see Shepard's camera with CDR (Commander) written on the side, the tongs under his hoses. Note the dirt on his boots and knees. The picture is taken toward the north. Shepard and Mitchell have come up a small rise and, out in the distance beyond the boulder, we can see a large crater..
