SpaceX’s third Falcon Heavy rocket took off from the Kennedy Space Center in a predawn launch Tuesday, delivering two dozen research and weather observation spacecraft into orbit on a marathon three-and-a-half mission for the U.S. Air Force. The mission included the successful landing of the Falcon Heavy’s two side boosters back at Cape Canaveral, and a SpaceX recovery boat netted part of the rocket’s payload fairing for the first time.

The deal comes roughly two months after Firefly inked a deal with Lockheed Martin for up to 25 launches in a similar timeframe. The first Alpha launches under this new contract would launch no earlier than 2027.
