Unlike the Ranger missions, which had hard impact
landings on the Moon, Surveyor 1 is the first U.S spacecraft to
make a soft landing. Settling down at a site called Flamsteed in
Oceanus Procellarum, Surveyor 1 sends back 11,240 pictures of the
lunar surface, revealing details as small as 2 millimeters (1/12th
inch). The lander operates until January 7, 1967.
