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

Venera 4 consisted of a 3.5 meter high main bus carrying a 383 kilogram lander probe with vital instruments encased in a pressure vessel. The probe was designed to withstand high temperatures, pressures, and accelerations. The bus was powered by 2.5 square meters of solar panel "wings" with a span of 4 meters. A cone-shaped omni-directional

The Venera 13 and 14 landers (launched Oct. 30 and Nov. 4, 1981, respectively) analyzed a number of nonradioactive elements in the surface rocks, finding them similar to earthly basalts; the landers also returned colour images of rocky landscapes bathed in yellow-orange sunlight that filtered through the clouds. Venera 15 and 16 (launched June

The Russian Venera 4 was successfully launched towards the planet Venus with the announced mission of direct atmospheric studies. On 18 October 1967, the descent vehicle entered the Venusian atmosphere. Signals were returned by the spacecraft, which deployed a parachute after braking to subsonic velocity in the Venusian atmosphere, until it

Taking advantage of the same launch window to Venus, the Soviet Union launched Venera 4 on June 12, with a goal to study the planet's atmosphere and land a capsule on the planet's surface. After a 128-day flight from Earth, on Oct. 18, Venera 4 released its 844-pound entry probe. The capsule entered the planet's atmosphere on the night

Only four spacecraft have ever returned images from Venus' surface. The world next door doesn't make it easy, with searing heat and crushing pressure that quickly destroy any lander. In 1975 and 1982, four of the Soviet Union's Venera probes captured our only images of Venus' surface. The Veneras, which mean "Venus" in Russian

Venera 4 is the first successful attempt to reach Venus after three failed Soviet missions. Venera 3 came closest, and successfully reached the planet, but communications had already failed, making the mission a failure. Within the next few days, the American spacecraft Mariner 5 is also expected to arrive at Venus.

The Venera 5 spacecraft was very similar to Venera 4 although it was of a stronger design. It comprised a bus with a mass of 1130 kg which held the descent probe. The probe was spherical with a mass of 405 kg and was designed for decelerations as high as 450-g. Venera 5 and 6 were designed with smaller parachutes (15 square meters) than Venera
