Artificial Earth Satellite Socks
Description: Molniya (Russian: Молния; IPA: [ˈmolnʲɪjə] ( listen), "Lightning") was a military communications satellite system used by the Soviet Union. The satellites were placed into highly eccentric elliptical orbits known as Molniya orbits, characterised by an inclination of +63.4 degrees and a period of around 12 hours. Such orbits allowed them to remain visible to sites in polar regions for extended periods, unlike geostationary satellites in geosynchronous orbits with a 24-hour orbital period.[1] The Molniya program was authorized by a government decree in late 1960. The first launch took place on June 4, 1964 and ended in failure when the 8K78 booster core stage lost thrust 287 seconds into launch due to a jammed servo motor. The next...
Description: Sputnik 1 was the first artificial Earth satellite. The Soviet Union launched it into an elliptical low Earth orbit on 4 October 1957, orbiting for three weeks before its batteries died, then silently for two more months before falling back into the atmosphere. It was a 58 cm (23 in) diameter polished metal sphere, with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable even by radio amateurs,[6] and the 65° inclination and duration of its orbit made its flight path cover virtually the entire inhabited Earth. This surprise success precipitated the American Sputnik crisis
