Luna21-E.jpgLuna 21 and Lunokhod 2: a new "Moon-Walk"104 visiteThe Lunar Rover stood 135 cm high and had a mass of 840 Kg. It was about 170 cm long and 160 cm wide and had 8 wheels, each with an independent suspension, motor and brake. The Rover had two speeds: ~1 km/hr and ~2 km/hr.
Lunokhod 2 was equipped with 3 TV cameras, one mounted high on the Rover for navigation, which could return HR images at different rates (3,2; 5,7; 10,9 or 21,1 seconds per frame). These images were used by a five-man team of controllers on Earth who sent driving commands to the Rover in real time.
Power was supplied by a solar panel on the inside of a round hinged lid which covered the instrument bay, which would charge the batteries when opened. A Polonium-210 isotopic heat source was used to keep the Rover warm during the Lunar Nights.
There also were 4 panoramic cameras mounted on the Rover.
