===Soyuz=== {{Main|Soyuz (spacecraft)}} [[File:Soyuz-TMA descent module.jpg|thumb|right|150px|The Soyuz spacecraft, with reentry capsule (Descent Module) highlighted]] In 1963, Korolev first proposed the three-man Soyuz spacecraft for use in Earth orbit assembly of a lunar exploration mission. He was pressured by Soviet premier [[Nikita Khrushchev]] to postpone development of Soyuz to work on Voskhod, and later allowed to develop Soyuz for space station and lunar exploration missions. He employed a small, lightweight bell-shaped reentry capsule, with an orbital crew module attached to its nose, containing the bulk of the mission living space. The service module would use two panels of electric [[solar cell]]s for power generation, and contained a propulsion system engine. The [[Soyuz 7K-OK|7K-OK model]] designed for Earth orbit used a {{convert|2810|kg|lb|adj=on}} reentry module measuring {{convert|2.17|m|ft|sp=us}} in diameter by {{convert|2.24|m|ft|sp=us}} long, with an interior volume of {{convert|4.00|m3|ft3|sp=us}}. The {{convert|1100|kg|lb|adj=on}} spheroidal orbital module measured {{convert|2.25|m|ft|sp=us}} in diameter by {{convert|3.45|m|ft|sp=us}} long with a docking probe, with an interior volume of {{convert|5.00|m3|ft3|sp=us}}. The total spacecraft mass was {{convert|6560|kg|lb}}. Ten of these craft flew crewed after Korolev's death, from 1967 to 1971. The first ([[Soyuz 1]]) and last ([[Soyuz 11]]) resulted in the first in-space fatalities. Korolev had developed a {{convert|9850|kg|lb|adj=on}} [[Soyuz 7K-LOK|7K-LOK]] variant for use in the lunar mission, but this was never flown crewed. The Russians continued to develop and fly the Soyuz to this day.
