Status: Study 1966.
This vehicle was to be carried to the lunar surface by a Surveyor and capable of traveling freely across the surface.
The mission consisted of measurements of lateral variation of surface and subsurface parameters and investigation of specific lunar structural and morphological problems which would require extreme landing accuracy for a stationary lander. The vehicle was to be operated in lunar day only over a total mission duration of 90 days. To minimize the number of earth stations to be used, the vehicle was operated for 8 hr/day maximum. The total range required was 40 km, which provided for a statistical sampling of an area 3200 m around the landing point. Payload for instruments was only 4 kg.
