Live coverage: Falcon 9 soars into space with DSCOVR

A Falcon 9 rocket was raised into position at pad 39A on Sunday for a customary test firing of its nine first stage Merlin engines. The rocket is being readied for a launch Thursday with a Dragon capsule carrying supplies to the International Space Station.

This was the 230th launch of Starlink V2 Mini satellites to date. SpaceX accomplished liftoff of the Starlink 10-21 mission from pad 40 at Cape Canaveral Space Force Station at 11 a.m. EDT (1500 UTC).

Returning home from more than a month in orbit, a SpaceX Dragon supply ship departed the International Space Station and parachuted into the Pacific Ocean on Sunday with nearly two tons of research specimens and hardware, including mice sent up to investigate how spaceflight affects eyesight and locomotion.
