Lost · Partial success
A Venus lander launched from a Tyazheliy Sputnik, whose entry body contained a radio communication system, scientific instruments, electrical power sources and medallions bearing the coat of arms of the U.S.S.R. Contact was lost on 16 February 1966, thought to be due to overheating; the spacecraft continued on to Venus and released its lander probe autonomously, which entered the atmosphere and reached the surface on 1 March 1966. NSSDCA calls that impact the first time a spacecraft reached the surface of another planet, and records that no planetary data could be returned.

Chronology
Mission timeline
Launch
Launched towards Venus from a Tyazheliy Sputnik
NSSDCA's launch/orbital information page gives the launch date and time as 1965-11-16T04:19:00Z, recorded at minute precision because the page prints a whole minute with zero seconds. The two NSSDCA pages disagree on the launch time by six minutes and the disagreement is recorded rather than resolved: the master catalog records that Venera 3 launched on 16 November 1965 at 04:13 UT from Baikonur Cosmodrome. The record follows the launch/orbital information page, which is the page that publishes launch times for every other record in this segment.
EarthMilestone
Mid-course correction performed
The master catalog records that a mid-course correction was performed on 26 December 1965.
Loss of contact
Contact lost, thought to be due to overheating
The master catalog records that on 16 February 1966 contact with Venera 3 was lost, that the loss was thought to be due to overheating of the spacecraft, and that the communications systems had failed before planetary data could be returned.
Impact
The lander reached the surface of Venus
The master catalog records that the spacecraft continued on to Venus and released its lander probe autonomously, which reached Venus, entered the atmosphere, and reached the surface on 1 March 1966, and that estimates of the impact site put it in an area between 20 N and 30 S latitude and 60 to 80 E longitude, with impact at approximately 06:56 UT. The launch/orbital information page prints 1966-03-01 under the heading Decay Date. Recorded at day precision because the page hedges the time itself with the word approximately.
