Suni Williams and Barry Wilmore were initially supposed to stay on the ISS for only one week, but they have now been in space for nearly three months.

Two Russian cosmonauts and an American astronaut on Thursday returned to Earth aboard a Soyuz space capsule after spending six months at the International Space Station.
      
Yelena Serova -- the first female Russian cosmonaut to have spent time on the ISS -- landed along with Alexander Samokutyaev and Barry Wilmore in snowy Kazakhstan just after sunrise.
