If you thought SpaceX was already making a fuss over the capabilities of both its existing Falcon 9 rocket and the upcoming Falcon Heavy, you haven't seen anything yet. The company has posted updated specs showing that both vehicles are more powerful than previously thought. A Falcon 9 is now known to be capable of hauling 50,265lbs to low Earth orbit, up from just shy of 29,000 pounds. The Falcon Heavy, meanwhile, will carry 119,930lbs instead of the previously promised 116,845lbs. Elon Musk chalks up the improved figures to more thorough testing -- SpaceX hasn't upgraded the hardware, at least not yet.
