'Great to see our friends arrive,' says stranded NASA astronaut

A pair of astronauts stranded for more than nine months on the International Space Station were a step closer to returning home Sunday after a replacement crew docked with the orbital outpost. 

The astronauts were shown on live TV embracing and hugging their counterparts in zero gravity on the space station shortly after their SpaceX Crew Dragon arrived at 0545 GMT. Stranded astronaut Suni Williams said it was "great to see friends arrive," after a replacement crew docked at the International Space station.
