Four fresh crew members bound for the International Space Station will finally enable the "stranded" Starliner astronauts to head for home.

The Starliner saga is a step closer to its end with the launch of a SpaceX vehicle that will relieve the astronauts who flew on the Boeing spacecraft.

The replacements for NASA’s two stuck astronauts launched to the International Space Station on Friday night, paving the way for the pair’s return after nine long months. Butch Wilmore and Suni Williams need SpaceX to get this relief team to the space station before they can check out.
