World's most powerful rocket... The maiden flight of SpaceX's (Private:SPACE) Falcon Heavy is scheduled for 1:30 p.m. from the Kennedy Space Center. Following liftoff, two of the rocket's cores will return to the landing pad, while the third core will land on a droneship at sea. As for the cargo? A cherry red Tesla (NASDAQ:TSLA) Roadster will be launched into a heliocentric deep space orbit while blasting David Bowie's Space Oddity.
