Apollo 15 was the first mission to use a lunar rover. One of the mission destinations was Rima Hadley. This sinuous rille, a river-like channel, is about 80 miles or 120 km in length and rises about 1,200 ft. or 370 m from the landing site. I created this composite of the side of Rima Hadley from images from NASA’s Project Apollo Archive. David Scott and James Erwin were the lunar crew, with Alfred Warden remaining in orbit.
