Home > Sputnik 7

Sputnik 7 was the first Soviet attempt at launching prode to explore Venus. The probe was successfully launched into Earth orbit with a SL-6/A-2-e launcher. The launch payload consisted of an Earth orbiting launch platform ( Tyazheliy Sputnik 4 ) and the Venera probe . The fourth stage (a Zond rocket ) was supposed to launch the Venera probe towards a landing on Venus after one Earth orbit but ignition failed, probably due to a faulty timer, and the spacecraft remained in Earth orbit. Because of its large size (6483 kg), the mission was originally thought by non-Soviet observers to be a failed manned mission, and later was described as a test of an Earth orbiting platform from which an interplanetary probe could be launched.

Sputnik 1Sputnik 1 was the first artificial satellite to be launched into orbit, on October 4, 1957. The satellite had a weight of about 83 kg (184 pounds). It had two radio transmitters and is believed to have orbited Earth at a height of about 250 km (150 miles)Sputnik programThe Sputnik program was a series of unmanned space missions launched by the Soviet Union in the late 1950s to demonstrate the viability of artificial satellites. The name "Sputnik" ("") comes from Russian where it means "satellite" or "fellow traveller".Sputnik 2Sputnik 2 was the second spacecraft launched into Earth orbit, at 19:12:00 on November 3, 1957, and was the first spacecraft to carry biological material. It was a 4 meter high cone-shaped capsule with a base diameter of 2 meters. It contained several com
