Three triangular space frame legs constructed of thin walled aluminum tubing connected by a central body consisting of a variety of solid boxes and stalks with panels and other objects projecting from it. Hydraulic shock absorber-equipped landing legs are hinged to each of the three lower corners; the legs terminate in circular crushable aluminum honeycomb footpads. A tubular mast at the apex of the frame supports a rectangular solar panel and a square high gain antenna. Two tubular booms attached to frame end in small, conical, low gain antennas. A selection of instrument boxes, vernier rockets and their fuel containers, and the TV camera are attached to the periphery of the frame. A long scissors-jack like arm that works the soil mechanics sample scoop is hinged horizontally and vertically to the frame.
