Four astronauts strapped into their SpaceX Crew Dragon spacecraft Monday and rode along for an automated maneuver to relocate the capsule to a different docking port outside the International Space Station. The relocation maneuver, which concluded with a link-up with the new docking port 7:08 a.m. EDT (1108 GMT), was the first of its kind for a Crew Dragon spacecraft.

Rocket Lab’s second flight-ready Electron rocket has arrived at its launch base in New Zealand for the company’s first mission to deliver commercial satellites into orbit.

With this launch, SpaceX is now one flight shy of tying the total number of Space Shuttle missions from this historic launch pad. This was the 81st flight of a Falcon rocket compared to the 82 total shuttle flights. Liftoff of the Starlink 6-51 mission happened at 5:26 p.m. EDT (2126 UTC).
