Lunokhod 1 (Луноход, moon walker in Russian; Аппарат 8ЕЛ № 203, vehicle 8ЕЛ№203) was the first of two unmanned lunar rovers landed on the Moon by the Soviet Union as part of its Lunokhod program. The Luna 17 spacecraft carried Lunokhod 1 to the Moon in 1970. Lunokhod 1 was the first remote-controlled robot “rover” to freely move across the surface of an astronomical object beyond the Earth.


Lunokhod 1 was a lunar vehicle formed of a tub-like compartment with a large convex lid on eight independently powered wheels. Its length was 2.3 metres (7 ft 7 in). Lunokhod was equipped with a cone-shaped antenna, a highly directional helical antenna, four television cameras, and special extendable devices to test the lunar soil for soil density and mechanical properties. An X-ray spectrometer, an X-ray telescope, cosmic ray detectors, and a laser device were also included. The vehicle was powered by batteries which were recharged during the lunar day by a solar cell array mounted on the underside of the lid. To be able to work in vacuum a special fluoride based lubricant was used for the mechanical parts and the electric motors (one in each wheel hub) were enclosed in pressurized containers. During the lunar nights, the lid was closed and a polonium-210 radioisotope heater unit kept the internal components at operating temperature. Lunokhod was intended to operate through three lunar days (approximately 3 Earth months) but actually operated for eleven lunar days.


We suppose that this date is very important for the history of space exploring. What do you think?

Of course that date it is important. Unmanned probes are the future of space exploration imo. Also they are first to scout places before we even start planning to send humans there. We’ve learned so much thanks to them. They deserve some respect.

The most important thing. Send the pressure cooker first and open a kitchen on the moon. The rest comes only later.

Well, this reminds me my never finished model of Lunochod (too thin “legs”) - time to download new one and make it: question is, how big - 1:43 to fit rest of wheeld models, 1:87 to fit winged ones or original 1:20?

(its for sale!: )
