SpaceX's Falcon Heavy Rocket Set to Launch! SpaceX's super sized Falcon Heavy rocket has a new launch date in spring 2016. It will be the world's most powerful operational rocket, capable of launching  53,000 kg into low-Earth orbit. In history, it only comes short of the Saturn V rocket, which powered NASA's Apollo missions to the moon. SpaceX originally promised to launch the rocket for the first time in 2013 but it was pushed back to this year. The process of SpaceX plan's to recover the stage one rocket boosters by landing them back on Earth after launch was spectacularly demonstrated in a video rendering earlier this year.  Take a look!
