Phase and distance are astronomical estimates for the current UTC time. Primary phase times below come from the U.S. Naval Observatory.
SIX CREWED LANDINGS
All six sites are on the Moon’s near side and are shown schematically.
Armstrong and Aldrin made humanity’s first landing on another world.
A precision landing near the robotic Surveyor 3 spacecraft.
Shepard and Mitchell sampled ejecta from the Imbrium impact.
The first Lunar Roving Vehicle explored mountains and a winding rille.
A geologic expedition into the Moon’s ancient highland terrain.
The final Apollo landing included geologist Harrison Schmitt.
Ice survives in permanently shadowed polar craters, while SOFIA also detected water on sunlit terrain.
Laser measurements show it recedes from Earth by roughly 3.8 centimeters each year.
With little moisture to damp vibrations, some lunar seismic events continue for many minutes.
