First Time The Largest SpaceX Rocket Will Employ Such Boosters

When SpaceX next launches a Falcon Heavy booster, currently set for June 22, it will use two previously-flow engine cores. The flight, part of the DOD's Space Test Program-2, will be the first time Falcon Heavy has flown on re-used boosters, and the third Falcon Heavy flight overall.

The website Inverse reports that the launch is currently set for 11:30 p.m. EDT from Launch Complex 39-A at the Kennedy Space Center.

The two side boosters will be the previously-flown engines. They were used to launch the Arabsat-6A satellite in April. The cores, which are the more powerful "Block 5" variant of the booster, landed back at the Kennedy Space Center after the launch.

The mission for the U.S. Air Force and Missile Space Center will carry 24 satellites into space. SpaceX says the mission is "among the most challenging launches" in the company's history with three deployment orbits and a propulsive passivation maneuver. The mission is expected to last a total of about six hours.

Along with deploying the satellites, the mission will gather data for future National Security Space Launch missions, and demonstrate the reliability of the reusable boosters to the Missile Systems Center.
