First Falcon Heavy Launch

First launch of the next-gen SpaceX Falcon Heavy launch vehicle. It’s equipped with a side booster separation system, so when the side boosters run out (using D engines) they will fall away from the center core (using an E engine) and fall back on their own. The launch went perfectly, but we lost all three cores - they’re either a backyard pool or low-earth orbit. Next steps: reuseability and landing legs
