Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is carried out mainly by astronomers with telescopes, its physical exploration though is conducted both by uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science. While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to become a reality. The world's first large-scale experimental rocket program was Opel-RAK under the leadership of Fritz von Opel and Max Valier during the late 1920s leading to the first crewed rocket cars and rocket planes, which paved the way for the Nazi era V2 program and US and Soviet activities from 1950 onwards. The Opel-RAK program and the spectacular publ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Race
The Space Race was a 20th-century competition between two Cold War rivals, the United States and the Soviet Union, to achieve superior spaceflight capability. It had its origins in the ballistic missile-based nuclear arms race between the two nations following World War II. The technological advantage demonstrated by spaceflight achievement was seen as necessary for national security, and became part of the symbolism and ideology of the time. The Space Race brought pioneering launches of artificial satellites, robotic space probes to the Moon, Venus, and Mars, and human spaceflight in low Earth orbit and ultimately to the Moon. Public interest in space travel originated in the 1951 publication of a Soviet youth magazine and was promptly picked up by US magazines. The competition began on July 30, 1955 when the United States announced its intent to launch artificial satellites for the International Geophysical Year. Four days later, the Soviet Union responded by declaring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salyut 1
Salyut 1 (DOS-1) (russian: Салют-1) was the world's first space station launched into low Earth orbit by the Soviet Union on April 19, 1971. The Salyut program followed this with five more successful launches of seven more stations. The final module of the program, ''Zvezda'' (DOS-8), became the core of the Russian segment of the International Space Station and remains in orbit. Salyut 1 was modified from one of the Almaz airframes, and was made out of five components: a transfer compartment, a main compartment, two auxiliary compartments, and the Orion 1 Space Observatory. Salyut 1 was visited by Soyuz 10 and Soyuz 11. The hard-docking of Soyuz 10 failed and the crew had to abort this mission. The Soyuz 11 crew achieved successful hard docking and performed experiments in Salyut 1 for 23 days. However, they were killed by asphyxia caused by failure of a valve just prior to Earth reentry, and are the only people to have died above the Kármán line. Salyut 1's mission w ...
