Home Astronaut Edwin E. Aldrin Jr., lunar module pilot, deploys two components of the Early Apollo Scientific Experiments Package on the surface of the Moon during the Apollo 11 extravehicular activity in 1969. A seismic experiment is in his left hand, and in his right is a laser-reflecting panel. Astronaut Neil A. Armstrong, mission commander, took this photograph.

This photograph shows the laser-ranging facility at the Goddard Geophysical and Astronomical Observatory in Greenbelt, Md. The facility helps NASA keep track of orbiting satellites. Both beams shown, coming from two different lasers, are pointed at NASA’s Lunar Reconnaissance Orbiter, which is orbiting the Moon. Here, scientists are using the visible, green wavelength of light.
