The private spaceflight company SpaceX has just announced a brand new, and gigantic, rocket. The Falcon Heavy will be 22 stories high, and have a cargo capacity of 117,000 pounds. The company has already arranged deals with NASA for resupplying the International Space Station with its Falcon 9 rocket and Dragon capsule. The Falcon Heavy, though, is intended for launching huge payloads into orbit for both government and commercial concerns. And this rocket will be able to do it cheaper than anyone else, by far.
