SpaceX Capsule Docks at ISS to Help Stranded Astronauts

There was sheer joy as the spacecraft that will carry stranded astronauts docks at the international space station. It's the first step in bringing home astronauts Suni Williams and Butch Wilmore. Through their 9-month ordeal as space castaways, Williams and Wilmore have stayed positive. They turned Christmas in space into a candy cane tossing party. Williams and Wilmore even staged a zero-gravity Olympics.
