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 program established a number of precedents in space exploration, among them being the first human-made devices to enter the atmosphere of another planet (Venera 3 on 1 March 1966), the first to make a soft landing on another planet (Venera 7 on 15 December 1970), the first to return images from another planet's surface (Venera 9 on 8 ...
Capsule of Venera-4 in Memorial Museum of Astronautics. The descent capsule of Venera 4 entered the atmosphere of Venus on October 18, 1967, making it the first probe to return direct measurements from another planet's atmosphere. The capsule measured temperature, pressure, density and performed 11 automatic chemical experiments to analyze the ...

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.
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 ...
After Venera 4's failure to reach the surface of Venus intact, the next 3MV probes (Venera 5 and 6) were strengthened again, this time to withstand a 450-g (compared to the 300-g entry of Venera 4) re-entry due to the 1969 launch window's higher velocity. The V-70 design took this further, with the capsule being slightly more egg-shaped.
2), and discovered that Venus's atmosphere was considerably denser than Venera 4 's designers had anticipated. [224] In an early example of space cooperation the data of Venera 4 was joined with the 1967 Mariner 5 data, analysed by a combined Soviet–American science team in a series of colloquia over the following year.
