Composite of photographs from the Apollo 15 mission, 1971

Today is Moon Day, commemorating the day in 1969 that Neil Armstrong first set foot on the Moon. Eleven other astronauts have gone on to follow in his bootsteps, including Commander David Scott and Lunar Module Pilot James Irwin during the Apollo 15 EVA 3 mission in 1971. We’ve stitched together their historic photos on the Moon’s surface to create this composite panorama of their landing site, where they spent three days conducting research. (If only they had selfie sticks back then.) Look for the ‘play’ button on our homepage to hear actual transmissions between the crew and mission control.
