A new video from SpaceX shows the spaceflight company's incredible plans for a reusable mega-rocket. The 2.5-minute Falcon Heavy rocket animation shows the spaceflight firm's plans to land the three boosters of its giant rocket back on Earth after launching missions to orbit. The three nine-engine boosters are equivalent to the booster used is used to power the core stage of the Falcon 9 rocket used to launch payloads to space currently. SpaceX representatives expect to start flights of the Falcon 9 Heavy later this year.
