The lunokhod missions were primarily designed to explore the surface and return pictures. This complimented the Luna series of missions that were intended to be sample return missions, but were mostly failures. The designs of the rovers were eerily prescient of the Spirit and Opportunity For details of each Lunokhod mission see:
