Watch the Falcon 9 and Crew Dragon arrive at the launch pad (members only)

SpaceX and NASA launched a planet-hunting satellite Wednesday from Cape Canaveral, two days after calling off a launch attempt to conduct additional guidance, navigation and control analyses. Liftoff occurred at 6:51 p.m. EDT (2251 GMT), and the first stage of the Falcon 9 rocket successfully landed on a drone ship in the Atlantic Ocean.

SpaceX’s Falcon 9 rocket flew its 300th mission on Thursday Feb. 16, lifting off from Vandenberg Space Force Base in California at 1:34 p.m. PST (4:34 p.m. EST, 2134 UTC) carrying another batch of satellites for the company’s Starlink internet service.

Two more roll-out solar arrays will ride a SpaceX cargo ship to the International Space Station this weekend, continuing a years-long mid-life station upgrade as NASA plans procurement of a final set of new solar wings to fully reinforce the lab’s power supply.
