The previous International Space Station (ISS), the Russian MIR property was built by the Soviet Union and its fall on Earth was scheduled in 2001 over the Pacific Ocean, which is the only way to financial and corporal power to finish that station. "
THE FIRST STEP
The first step of the International Space Station began in 1995 and involved only travel to the then existing space station, Mir, Russian ownership.There were more than two years of continuous stay and eleven links between various ferries and the MIR. As they passed the tests was gaining knowledge in technology, scientific research and space operations worldwide.
The MIR space station float in space for approximately fifteen years some 390 miles high with an inclination of 51.6 degrees. At the end of its useful life 86 325 laps completed around the Earth during that time Mir was the place where important studies were performed with advanced technology to investigate human beings stay for long periods in space. Normally the crew consisted of 2 or 3 astronauts and / or cosmonauts, but sometimes it was host for more than a month to more than 6 people at once.
Some of the research in the MIR includes the study of life in space, effects of microgravity, space technology experiments and detailed observations of the Earth.
NASA even used the MIR to prepare their astronauts for long stays in orbit, we must remember that the Mir astronauts received dozens of nations. NASA activities on Mir included the following missions: STS-60, STS-63, STS-71, STS-74, STS-76, STS-79, STS-81, STS-84, STS-86, STS -89, and STS-91, each docked with the Mir, all with a view to prepare the construction of the International Space Station.
