Universe Today: Early this morning a Soyuz spacecraft returned three astronauts to Earth from the International Space Station (ISS). After nearly six months in space, Alexander Samokutyaev, Andrey Borisenko, and NASA flight engineer Ronald Garan touched down safely in the southern steppes of Kazakhstan. For the next two months the ISS will be maintained by the three remaining astronauts, until the next three-person crew will arrive. Flights to and from the ISS were disrupted after a freighter carried by a Soyuz rocket crashed to Earth in August. Russia has been working to determine exactly how and why the rocket crashed.
