Venera 12 was launched on 14 September 1978 at 02:25:13 UTC. [3] After separating from its flight platform on 19 December 1978, the Venera 12 lander entered the Venus atmosphere two days later at 11.2 kilometres per second (7.0 mi/s). During its descent, the lander employed aerodynamic braking followed by parachute braking, ending with ...
Venera 1 was launched on 12 February 1961. Telemetry on the probe failed seven days after launch. It is believed to have passed within 100,000 km (62,000 mi) of Venus and remains in heliocentric orbit. Venera 2 launched on 12 November 1965, but also suffered a telemetry failure after leaving Earth orbit.
On February 12, 1961, the Soviet spacecraft Venera 1 was the first flyby probe launched to another planet. An overheated orientation sensor caused it to malfunction, losing contact with Earth before its closest approach to Venus of 100,000 km.
Venera 13 (Russian: Венера-13 'Venus 13') was part of the Soviet Venera program meant to explore Venus. Venera 13 and 14 were identical spacecraft built to take advantage of the 1981 Venus launch opportunity. The probes were launched five days apart, with Venera 13 launching on 30 October 1981 at 06:04 UTC and Venera 14 launching on 4 ...
The SIGNE 2 detectors were simultaneously flown on Venera 12 and Prognoz 7 to allow triangulation of gamma ray sources. Before and after Venus flyby, Venera 11 and Venera 12 yielded detailed time-profiles for 143 gamma-ray bursts, resulting in the first ever catalog of such events. The last gamma-ray burst reported by Venera 11 occurred on ...
From 1961 to 1984, the Soviet Union developed the Venera probes for surface mapping by radar. The Venera 4 (on October 18, 1967) was the first lander to make a soft landing on Venus (also the first for another planetary object). The probe operated for about 23 minutes before being destroyed by the Venusian atmosphere.
Venera 7 (Russian: Венера-7, lit. 'Venus 7') was a Soviet spacecraft, part of the Venera series of probes to Venus . When it landed the Venusian surface on 15 December 1970, it became the first spacecraft to soft land on another planet and the first to transmit data from there back to Earth .
