In this photo, Alan Shepard takes his first steps on the moon's Fra Mauro highlands during the 1971 Apollo 14 mission, and scans the lunar horizon. While Shepard is most remembered for hitting a golf ball on the moon, he also helped collect almost 100 pounds of moon rocks, and conducted several seismic experiments to investigate the region's "moonquakes." Shepard says the public tends to forget that it was "a hell of a good flight. Someone says, 'Oh yeah, you were the third to land on the moon--but didn't you play golf up there?' I probably should've known that was going to happen."
