physical and mechanical properties of the surface soil were studied at more than 500 points along the route, and analyses of its chemical composition were made at 25 points.The joint processing of the television pictures of the terrain, telemetric information and the study of the physical and mechanical properties of lunar soil and its chemical composition made it possible to evaluate the topographic and morphological features of the moon's surface in the explored area. Besides that, cosmic X-rays were also measured systematically for a considerable space of time to look more deeply into the radiation on the Moon. The lunar rover stopped functioning after its isotope source of heat energy became exhausted. Its successful performance from November 17, 1970, to October 4, 1971, had confirmed that its design and testing methods were reliable and correct.
(37) The lunokhod's trouble-free operation was a triumph of automation and a milestone in the study of the Moon. Future achievements in exploring this celestial body and other planets are hard to conceive without automatic probes similar to Luna-16 and Lunokhod-1.

THE "MARS" MISSIONS
(1) The first Mars-bound probe was launched on November 1, 1962. Thereafter space technology has made impressive advances. Soviet space vehicles soft-landed on the Moon and Venus and brought back samples of lunar rock. Others continuously explore near-earth and near-lunar space.
(2) On May 19 and May 28, 1971, the Mars-2 and Mars-3 automated probes were fired. The orbital vehicles were put into two markedly different areo-centric orbits on November 27 and December 2 respectively for the purpose of probing the planet itself and its environs. The minimum distance between the planet and both probes was approximately 1,500 km; the maximum distance for the Mars-2 probe was 25,000 km, and for the Mars-3 - over 200,000 km.
(3) A capsule containing the Soviet national emblem was sent to the
surface of Mars by the Mars-2 while it was near the planet,          :
,   (4) The Mars-3 descent module landed between the regions called
Electris and Phaethontis. The signals of its panoramic television ca-2 meras were received at a specified time over two independent channels.;;
The signal was clear, without interference, but soon transmission ceased. .
(5) The reason for this is impossible to determine. The failure may have been due to the conditions at the landing area which are completely unknown, or else it nay have been caused by the dust storm that was sweeping the planet at the time.                ,'
(6) The fact that a soft-landing has been made on the surface of Mars opens up prospects for exploring the planet by direct methods in the near future,
