New crew arrives at International Space Station

Four astronauts, launched by SpaceX for NASA, arrived at the International Space Station on Wednesday night.The astronauts arrived at the space station just 16 hours after a predawn liftoff from Kennedy Space Center that thrilled spectators.

SpaceX has now launched five crews for NASA and two private trips in just under two years. Elon Musk's company is having an especially busy few weeks: It just finished taking three businessmen to and from the space station as NASA’s first private guests.A week after the new crew arrives, the three Americans and German they’re replacing will return to Earth in their own SpaceX capsule.
