|Astronauts Pay a Visit to Surveyor 3
A little more than two years after it landed on the moon with the goal of paving the way for a future human mission, the Surveyor 3 spacecraft gets a visit from Apollo 12 Commander Charles Conrad Jr. and astronaut Alan L. Bean, who snapped this photo on November 20, 1969. Image credit: NASA
After Surveyor 1's initial studies of the lunar surface in 1966, Surveyor 3 made further inroads into preparations for human missions to the moon. Using a surface sampler to study the lunar soil, Surveyor 3 conducted experiments to see how the lunar surface would fare against the weight of an Apollo lunar module.
The moon lander, which was the second of the Surveyor series to make a soft landing on the moon, also gathered information on the lunar soil's radar reflectivity and thermal properties in addition to transmitting more than 6,000 photographs of its surroundings.
