What was the first space station?
Like many other first surveys of the universe, the first space station was opened by the Soviet Union. Like several other stories about the universe, it ended in tragedy. Salyut 1 was launched on April 19, 1971, just two years after the Americans landed on the moon, was 15.6 x 4 meters (51.18 x 13.12 feet) with a 99 cubic meter (3,496.15 cubic tracks) of the interior - similar to the size of a school bus. The space station had a dry weight of 18,425 kg (40 620 pounds) and was launched from the Baikonur Cosmodrome in today's Kazakhstan.
The purpose of Salyut 1 was to put the first device for long -term research and observation in orbit. It was designed both as evidence of the concept for space stations in general and for experiments and observations that satellites could not function themselves. Salyut is one of the nine cosmic stations that have ever been inhabited since November 2007.
The space station had four sections, three of which were tiscuccared. It was the main compartmentT, transmission compartment, auxiliary compartment and storage compartment. Like all the space stations so far run, the crew was launched, and the crew arrived later through a separate vehicle.
Unfortunately, the use of a new space station has been problematic from the beginning. Soyuz 10 was launched on April 23, 1971 and planned to be the first visit to the space station in history. Although the capsule physically anchored the station, the connection was not safe enough to allow the hatches to open without risking the vacuum leakage. The hatches inside Soyuz seemed to be stuck. The astronauts were forced to return to the ground without entering the station. As another complications, toxic vapors flooded the reentry capsule, which caused one of the cosmonauts to be slapped, although all three eventually survived the suffering of any other injuries.
Second attempt to visit the station, Soyuz 11, was theLess successful. The capsule was launched on June 6, 1971 from Baikonur, the capsule became a station and three cosmonauts got in and became the first people to visit the space station. They stayed there for 22 days, at that time the record for the duration of space. Cosmonaut Viktor Patsayev became the first person to use a telescope in space.
The disaster happened during the reentry. After an apparently normal reentry, he opened the capsule recovery team and found that all astronauts were dead. The error was monitored to the respiratory valve between the descending module and the orbiting module. Some explosive screws, which were supposed to shoot gradually, instead fired at the same time disruption to the valve seal. The pressure was lost to 168 kilometers (104 miles) and cosmonauts stewed when the air escaped from the cabin. They could be rescued if they had pressure suits on descent, as is nowstandard for all operations in orbit and reentry.
Three astronauts who died remain the heroes of the universeNot enthusiasts everywhere. Their death emphasizes the danger of space travel and the need to develop extremely safe systems than it will be possible to take most of humanity steps into space.
