A space station is a structure designed for human beings to live on in outer space, for periods of weeks, months, or even years. They are used to study the effects of long-term space flight on the human body and to carry out scientific experiments in space. Space stations do not have a major propulsion system and are unable to land back on Earth, Instead, other vehicles are used to transport crew, equipment and supplies to-and-from the station.
Amazing
Weightlessness can make an astronaut grow several centimeters taller during a long mission in space.
Mir
Mir was a Russian space station, and the largest serving station ever. It was launched in 1986 and
made more than 76.000 orbits of the Earth. The last crew left it in 1999. Mir was built in stages. It weighed 125 tonnes and had six docking ports and two living rooms, plus a bathroom and two small cabins. It was crashed into the Pacific Ocean in March 2001.
Life on board
Some inhabitants of the Mir space station spent more than a year on board. The station experienced
power failures and crashes with ferry craft bringing supplies. The large panels shown here are solar cells used to make electricity from sunlight.
