Class: Planetary. Type: Lunar. Nation: USA.

The Surveyor Block II spacecraft was imagined as an unmanned scout that could reconnoiter a specific lunar landing site for Apollo and assist the manned Lunar Module in making a precise touch down. A number of possible active and passive landing aids were considered, including: a Surveyor deployed transponder; an active radio homing device; a passive radar device (corner reflector); visual markers. In the end the concept, similar to one using the LK and Lunokhod in the Soviet Union, was abandoned.
