Sputnik Program
Sputnik (Спутник, Russian for "satellite"NOTE: The Russian word "sputnik" can have many meanings: "satellite", "travelling companion", "fellow traveller", etc. However, in astronomy, it means only "satellite".) is a spacecraft launched under the Soviet space program. "Sputnik 1", "Sputnik 2" and "Sputnik 3" were the official Soviet names of those objects, and the remaining designations in the series ("Sputnik 4" and so on) were not official names but names applied in the West to objects whose original Soviet names may not have been known at the time. Spacecraft officially named ''Sputnik'' * Sputnik 1, the first artificial satellite to go into orbit, launched 4 October 1957 * Sputnik 2, the first spacecraft to carry a living animal (the dog Laika) into orbit, launched 3 November 1957 * Sputnik 3, a research satellite launched 15 May 1958 Spacecraft with names containing ''Sputnik'' Being the Russian term for "satellite", the word ''Sputnik'' has appeared in the names of ...

Sputnik 1
Sputnik 1 (; see § Etymology) was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries ran out, and continued in orbit for three months until aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. It was a polished metal sphere in diameter with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth. The satellite's unanticipated success precipitated the American Sputnik crisis and triggered the Space Race, part of the Cold War. The launch was the beginning of a new era of political, military, technological and scientific developments. The word ''sputnik'' is Russian for ''satellite'' whe ...

Kosmos 1
Kosmos 1 (russian: Космос 1 meaning ''Cosmos 1''), also known as DS-2 No.1 and occasionally in the West as Sputnik 11 was a technology demonstration and ionospheric research satellite launched by the Soviet Union in 1962. It was the first satellite to be designated under the Kosmos system, and the first spacecraft launched as part of the Dnepropetrovsk Sputnik programme to successfully reach orbit. History Kosmos 1 was a DS-2 satellite, the first of two to be launched.

Korabl-Sputnik 5
Korabl-Sputnik 5 (russian: Корабль-Спутник 5 meaning ''Ship-Satellite 5'') or Vostok-3KA No.2, also known as Sputnik 10 in the West, was a Soviet spacecraft which was launched in 1961, as part of the Vostok programme. It was the last test flight of the Vostok spacecraft design prior the first crewed flight, Vostok 1. It carried the mannequin Ivan Ivanovich, a dog named Zvezdochka ("Starlet",Siddiqi, p267 or "Little star"), television cameras and scientific apparatus. Background A spacecraft of the design ''Vostok 3KA'' had only been launched once before, which was on March 9, 1961. This mission was called Korabl-Sputnik 4, and it was a complete success.Siddiqi, p.266 Prior to Korabl-Sputnik 4, the two previous missions in the Vostok programme were both launched in December 1960, and both ended in failure. Only days before the launch of Korabl-Sputnik 5, the cosmonaut team, which consisted of 20 men, experienced its first fatality. Cosmonaut candidate Valentin Bond ...

Korabl-Sputnik 4
Korabl-Sputnik 4 (russian: Корабль-Спутник 4 meaning ''Ship-Satellite 4'') or Vostok-3KA No.1, also known as Sputnik 9 in the West, was a Soviet spacecraft which was launched on 9 March 1961. Carrying the mannequin Ivan Ivanovich, a dog named Chernushka, some mice and the first guinea pig in space, it was a test flight of the Vostok spacecraft. Korabl-Sputnik 4 was launched at 06:29:00 UTC on 9 March 1961, atop a Vostok-K carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome. It was successfully placed into low Earth orbit. The spacecraft was only intended to complete a single orbit, so it was deorbited shortly after launch, and reentered on its first pass over the Soviet Union. It landed at 08:09:54 UTC, and was successfully recovered. During the descent, the mannequin was ejected from the spacecraft in a test of its ejection seat In aircraft, an ejection seat or ejector seat is a system designed to rescue the pilot or other crew of an aircraft ...

Venera 1
''Venera 1'' (russian: Венера-1 meaning ''Venus 1''), also known as Venera-1VA No.2 and occasionally in the West as ''Sputnik 8'' was the first spacecraft to fly past Venus, as part of the Soviet Union's Venera programme. Launched in February 1961, it flew past Venus on 19 May of the same year; however, radio contact with the probe was lost before the flyby, resulting in it returning no data. Spacecraft ''Venera 1'' was a probe consisting of a cylindrical body in diameter topped by a dome, totalling in height. This was pressurized to with dry nitrogen, with internal fans to maintain even distribution of heat. Two solar panels extended from the cylinder, charging a bank of silver-zinc batteries. A 2-metre parabolic wire-mesh antenna was designed to send data from Venus to Earth on a frequency of 922.8 MHz. A 2.4-metre antenna boom was used to transmit short-wave signals during the near-Earth phase of the mission. Semidirectional quadrupole antennas mounted on t ...

Korabl-Sputnik 3
Korabl-Sputnik 3 (russian: Корабль-Спутник 3 meaning ''Ship-Satellite 3'') or Vostok-1K No.3, also known as Sputnik 6 in the West, was a Soviet spacecraft which was launched in 1960. It was a test flight of the Vostok spacecraft, carrying two dogs; Pcholka and Mushka ("little bee" and "little fly"; affectionate diminutives of "pchela" and "mukha", respectively), as well as a television camera and scientific instruments. Korabl-Sputnik 3 was launched at 07:30:04 UTC on 1 December 1960, atop a Vostok-L carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome. It was successfully placed into low Earth orbit. The flight lasted one day, after which the spacecraft was deorbited ahead of its planned recovery. The deorbit burn began at 07:15 UTC on 2 December, however the engine did not cut off as planned at the end of the burn, and instead the spacecraft's fuel burned to depletion. This resulted in it reentering the atmosphere on a trajectory which might have permitt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
