SpaceX just aced a critical Air Force test of its Falcon Heavy rocket

On Tuesday afternoon—a little more than 12 hours after the launch of a Falcon Heavy rocket from Kennedy Space Center in Florida—the US Air Force's Space & Missile Systems Center declared that all had gone well with the complicated mission. "All satellites are on orbit and have made contact," the Air Force unit tweeted.

SpaceX had a lot on its plate with Tuesday morning's launch, which occurred at 2:30am ET (06:30 UTC). Once again, the company recovered the two side-mounted Falcon 9 first stage boosters at a landing site along the Florida coast. But for the second time out of three Falcon Heavy launches, SpaceX was unable to land the center core on a drone ship in the Atlantic Ocean. This is perhaps understandable because, due to mission requirements, the center core used in Tuesday's launch had to shed more energy than any previous launch—its attending drone ship was positioned more than 1,200km away from the launch site.
