Heavy..

Falcon Heavy has a successful second launch and lands all three cores for reuse.

If only NASA could get off the slow money wasting process of building, maybe one of their rockets would be flying today....

NASA can't seem to be able to take engines already flown in space, boosters that have already flown in space, avionics that have flown in space and put them together in a reasonable time to make a new rocket out of old proven parts..
