SpaceX again successfully landed its Falcon 9 rocket on a drone ship at sea after launching it into space from Florida early Friday. The landing marks the third time SpaceX has recovered the booster post-launch and the second time the unmanned rocket has landed intact on the ship. SpaceX had previously said that it was unlikely the Falcon 9 would make the landing as it would be “subject to extreme velocities and re-entry heating.” The successful mission sent a Japanese communications satellite into orbit. CEO Elon Musk celebrated by posting on Twitter, “Woohoo!!”
