Venera 4 (Russian: Венера-4, lit. 'Venus-4'), also designated 4V-1 No.310, was a probe in the Soviet Venera program for the exploration of Venus.The probe comprised a lander, designed to enter the Venusian atmosphere and parachute to the surface, and a carrier/flyby spacecraft, which carried the lander to Venus and served as a communications relay for it.
All Soviet spacecraft that never left Earth orbit were customarily renamed "Kosmos", regardless of the craft's intended mission. The name is also given to other Soviet/Russian spacecraft that are intended to—and do reach Earth orbit. — Venera 4: 4V-1 No.310: Atmospheric probe: 12 June 1967: 18 October 1967 —
(3MV-1 No.4) 2 April 1964: OKB-1 Soviet Union: Flyby/Lander Spacecraft failure Electronics shorted out, communications lost before flyby. [11] Flew past Venus on 14 July 1964. Molniya-M: Venera 2 (3MV-4 No.4) 12 November 1965: OKB-1 Soviet Union: Flyby Spacecraft failure Flew past Venus on 27 February 1966, closest approach at 02:52 UTC.
Venera 4's battery ran out while still slowly floating through the massive atmosphere, and Venera 5 and 6 were crushed by high pressure 18 km (60,000 ft) above the surface. The first successful landing on Venus was by Venera 7 on December 15, 1970 — the first successful soft (non-crash) landing on another planet, as well as the first ...
This is a list of spacecraft powered by non-rechargeable batteries.While most spacecraft are powered by longer-lasting power sources such as solar cells or radioisotope thermoelectric generators, which can provide power for years to decades, some have been powered by primary (non-rechargeable) electrochemical cells, which provide runtimes of minutes to months.
The spacecraft was named Kosmos 96, part of a series typically used for military and experimental satellites in order to cover up the failure. Had it departed Earth's orbit, it would have received the next designation in the Venera series, at the time Venera 4. Kosmos 96 was destroyed when it re-entered the Earth's atmosphere on 9 December 1965 ...
