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.
The Venera probes provided direct data regarding Venus' surface and atmosphere while also providing important information on electronics lifetime under Venus' harsh conditions. Venera 4 was the first successful probe, and showed that CO 2 is the main component in Venus' atmosphere.
Zond 3MV-1 No.2 [3] (or No. 4A [4]), also known as Venera 1964A in the West, was a Soviet spacecraft, which was launched in 1964 as part of the Zond program. Due to a problem with its carrier rocket third stage, it failed to reach low Earth orbit .
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 ...
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 ...
Venera 4V-2 (Russian: Венера 4В-2) was a series of two identical spacecraft sent to Venus by the Soviet Union, consisting of Venera 15 and Venera 16. [1] Both uncrewed orbiters were to map the surface of Venus using high resolution imaging systems. The spacecraft were identical and based on modifications to the earlier Venera space probes.
The uncrewed Starship spacecraft was apparently destroyed during its first flight launch of 2025 that blasted off from south Texas. SpaceX's Starship spacecraft is apparently destroyed after ...
