Astronaut Alfred M. Worden, command module pilot of the Apollo 15 mission, floats in space outside of the spacecraft during his transearth extravehicular activity (EVA). This picture was taken from a frame of motion picture film exposed by the 16mm Maurer camera mounted on the hatch of the Command Module. During his EVA Worden made on inspection of the Service Module's Scientific Instrument Module (SIM) bay and retrieved the film cassettes from the Panoramic Camera and Mapping Camera. The EVA occurred when the spacecraft was homeward bound approximately 171,000 nautical miles from Earth.
