Watch the Falcon Heavy fire up its engines

SpaceX’s Crew Dragon spacecraft closed out a six-day test flight in low Earth orbit Friday with an on-target splashdown in the Atlantic Ocean, and officials hailed the ship’s performance before it flies with astronauts for the first time later this year.

A SpaceX-owned Dragon cargo craft left the International Space Station on Friday and flew back to Earth for a parachute-assisted splashdown in the Pacific Ocean with a dozen mice and more than 3,000 pounds of experiment specimens and space hardware.

Another 60 Starlink satellites are ready for launch Wednesday to beam Internet signals to future SpaceX consumers as the company seeks regulatory approval to deploy thousands more spacecraft at lower altitudes than originally planned.
