in geosynchronous orbit, including cold gas thrusters, electric propulsion, and a global position receiver. A second LDPE was launched on 1 November 2022 on a Falcon Heavy rocket as part of the USSF-44 mission, and it carried three separable payloads and three hosted payloads. The separable payloads included Alpine, a cubesat from Millennium Space Systems to demonstrate GEO small satellite designs and leverage commercial GEO communications; LINUSS, a Lockheed Martin project consisting of two 12U cubesats to test GEO satellite servicing; and Tetra-1, an SSC small satellite designed as a pathfinder for innovative methods of space vehicle design and on-orbit Tactics Techniques and Procedures development. The hosted payloads included: Mustang, a small sized communications experiment; Xenon, a commercial off-the-shelf component maturation for flight at GEO; and Energetic Charged Particle-Lite, an SSC space weather sensor. A third LDPE was launched on 15 January 2023 on a Falcon Heavy as part of the USSF-67 mission, and it carried five hosted payloads. Among those, two belonged to the Space Systems Command: Catcher, a prototype sensor to provide local space domain awareness insights, and WASSAT, a sensor consisting of four cameras to search for and track other spacecraft and space debris. The other three payloads have been provided by the Space Rapid Capabilities Office and included two prototypes for space situational awareness missions and one to test encrypted space-to-ground communications.
