It’s finally launch day for the Falcon Heavy’s first mission, and SpaceX’s heavy-duty rocket platform is due to take off at 3:35 Pacific time. The launch will take a major communications satellite into orbit, and as an encore all three of the first stages will attempt to return to Earth and make soft landings. Success means the inauguration of a new era in spaceflight.

Falcon Heavy was first tested last February, with a dummy payload of a Tesla Roadster and a mannequin dubbed “Starman,” now somewhere past the orbit of Mars. Since then the rocket has gained a few improvements, including a reinforced center core that should help enable it to return safely.
