The place of impact was firstly announced as (coast of Mare Nubium), but later it was estimated as (near crater Copernicus). It was the second Soviet spacecraft to reach the surface of the Moon, following "Luna 2" in 1959. An observatory noted a plume produced by the impact, which was visible for ten minutes.

Exploration of Mars in mid-May 1971 and reached Mars about seven months later. On November 27, 1971 the lander of Mars 2 crash-landed due to an on-board computer malfunction and became the first man-made object to reach the surface of Mars. On 2 December 1971, the Mars 3 lander became the first spacecraft to achieve a soft landing, but its transmission was interrupted after 14.5 seconds. The Mars 2 and 3 orbiters sent back a relatively large volume of data covering the period from December 1971 to March 1972, although transmissions continued through to August. By 22 August 1972, after sending back data
