Which astronauts have lived on the Space Station? What's next? When ISS is completed it will cover an area as big as a football pitch and weigh tonnes. It would have been impossible to build ISS on the ground and then launch it into space in one go; there is no rocket big enough or powerful enough. To get round this problem the Space Station is taken into space piece-by-piece and gradually built in orbit, approximately km above the Earth's surface.

Although the bulk of research done on the station is focused on learning more about surviving in space, experiments outside of the space station are peering into the cosmos and attempting to learn more about the environment in which spacefaring humans might live.
One of these instruments, called NICER , is studying neutron stars, stellar corpses that are the densest objects in the known universe. Another, the Alpha Magnetic Spectrometer , is a particle physics experiment that is attempting to snare and analyze cosmic rays, the most fundamental components of the cosmos, to better understand the origins of the universe. In recent years, U. Back on Earth, teams are simulating these environments and studying the psychological challenges associated with isolation, in an attempt to better understand who might be best suited for space flights of even longer duration.
Until , astronauts were ferried to the station by the U. After the U. Piloted by NASA astronauts Doug Hurley and Bob Behnken, this crucial test flight departed the station in early August, ending in a safe and successful splashdown off the western coast of Florida. Now, astronauts can once again launch into orbit from U. For now, plans include operating the space station through at least , although that timeline could be extended.

Thursday's mishap began about three hours after the multipurpose Nauka module had latched onto the space station, as mission controllers in Moscow were performing some post-docking "reconfiguration" procedures, according to NASA.
The module's jets inexplicably restarted, causing the entire station to pitch out of its normal flight position some miles above the Earth, leading the mission's flight director to declare a "spacecraft emergency," U.
Slideshow: Images from space. An unexpected drift in the station's orientation was first detected by automated ground sensors, followed 15 minutes later by a "loss of attitude control" that lasted a little over 45 minutes, according to Joel Montalbano, manager of NASA's space station program. Flight teams on the ground managed to restore the space station's orientation by activating thrusters on another module of the orbiting platform, NASA officials said.
In its broadcast coverage of the incident, RIA cited NASA specialists at the Johnson Space Center in Houston, Texas, as describing the struggle to regain control of the space station as a "tug of war" between the two modules.
