![]() The complex orbital maneuvers during the June 2019 mission for the military’s Space Test Program were required to place 24 satellite payloads into three distinct orbits. On the most recent Falcon Heavy mission, the rocket’s upper stage completed four burns over three-and-a-half hours on a demonstration flight sponsored by the Air Force. The rocket’s upper stage will fire several times to place the satellites into position more than 22,000 miles above the equator. The upper stage flight profile will include a coast lasting more than five hours between burns, making the USSF-44 mission one of SpaceX’s most demanding launches yet. The Falcon Heavy is expected to deliver the satellites on the USSF-44 mission to a high-altitude geosynchronous orbit. The TETRA 1 satellite alone would account for a small fraction of that mass. In the request for proposals for the USSF-44 launch, the Air Force told prospective launch providers to assume the combined mass of the two payloads is less than 8,200 pounds, or about 3.7 metric tons. But that was four years ago, and the Space Force has not released any updates to the final number of satellites assigned to the flight. The original procurement statement the Pentagon released to prospective launch providers for the USSF-44 mission indicated the mission would launch with two spacecraft. Military officials have released no additional details about TETRA 1’s mission. Built by Millennium Space Systems, a subsidiary of Boeing headquartered in El Segundo, California, the small spacecraft is designed to “prototype missions and tactics, techniques and procedures in and around geosynchronous Earth orbit,” Space Force officials said. One of the payloads assigned to launch on the USSF-44 mission is a microsatellite named TETRA 1. The Space Force has released little information about what the Falcon Heavy rocket will carry into orbit on the the USSF-44 mission. A military spokesperson told Spaceflight Now the USSF-44 payload issues are now resolved, without offering additional details. The USSF-44 mission was originally scheduled to launch in late 2020, but has been nearly two years by issues with the Space Force payload assigned to fly on the rocket. The long gap between Falcon Heavy launches has been caused by payload delays. The launch is expected to occur in daylight in the morning hours, but the Space Force has not officially released the launch time for the USSF-44 mission, the fourth flight of a SpaceX Falcon Heavy rocket and the first since June 2019. SpaceX ground teams at pad 39A will prepare the pad for the Falcon Heavy, which has a different configuration than the Falcon 9 with three Falcon rocket boosters connected together to triple the launcher’s total thrust. The Falcon Heavy rocket mission, codenamed USSF-44, is expected to be the next launch from Launch Complex 39A at Kennedy following the liftoff Wednesday of a Falcon 9 rocket and a Dragon capsule carrying a crew of four to the International Space Station.
