![]() If you let go of an object, it will float away. Actually living in space was another matter.Ĭontemporary space stations don’t spin to provide gravity. ![]() Yuri Gagarin’s voyage around Earth in 1961 proved humans could survive in space.

The ISS now consists of 16 modules: four Russian, nine US, two Japanese, and one European. What survived likely ended up under 5000 meters of water at the bottom of the Pacific Ocean. Mir was brought down in 2001, and broke up as it plummeted through the atmosphere. Mir was still in orbit when the first modules of the International Space Station were launched in 1998. ![]() The Soviet station Mir, launched in 1986, was the first to be built with a core to which other modules were added later. All of these were tube-shaped structures. The USA launched its first space station, Skylab, in 1973. The first space station was the USSR’s Salyut 1 in 1971, followed by another six stations in the Salyut programme over the next decade. Instead of spheres or wheels, real space stations turned out to be cylinders. The spinning wheel was championed by rocket scientist Wernher von Braun in the 1950s and featured in the classic 1968 film 2001: A Space Odyssey. In 1929, Hermann Noordung theorised a wheel-shaped space station that would spin to create “artificial” gravity. Inside were 13 spherical living chambers. The first fictional space station was Edward Everett Hale’s 1869 “ Brick Moon”.

This is 43% of all the people who have ever travelled in space.Īs future missions to the Moon and Mars are planned, it’s important to know what people need to thrive in remote, dangerous and enclosed environments, where there is no easy way back home. It has hosted 241 crew and a few tourists from 19 countries. The ISS is a collaboration between 25 space agencies and organisations. Twenty straight years of life in space makes the ISS the ideal “natural laboratory” to understand how societies function beyond Earth. The orbiting habitat has been continuously occupied ever since. November 2 marked 20 years since the first residents arrived on the International Space Station (ISS). A selfie taken by NASA astronaut Tracy Caldwell Dyson looking out of the ISS Cupola.
