SpaceX Crew Dragon caps flawless rendezvous with station docking

A SpaceX Crew Dragon capsule caught up with the International Space Station early Saturday and glided in for a picture-perfect docking, bringing four fresh astronauts to the outpost and setting the stage for four others to return to Earth next week aboard a second SpaceX ferry ship.

Completing a computer-orchestrated rendezvous that began Friday with a launch from the Kennedy Space Center, the "Crew-2" capsule approached the station from behind and below, looping up to a point directly ahead of the lab while both spacecraft streaked through space at more than 17,000 mph. That's fast enough to cover more than 80 football fields in one second, but the rendezvous appeared to play out in slow motion as the Crew Dragon inched closer and closer with a precisely calculated, slightly different velocity.
