SpaceX Satellites Conduct First Laser Data Exchange for US Military

Two SpaceX satellites equipped with Tesat terminals have successfully conducted a laser data exchange, marking a significant achievement for the U.S. Space Development Agency (SDA). This event, which took place on September 3, 2024, is the first demonstration of military-grade optical communications in space using the required standards for SDA satellites. The satellites established a communication link in under 100 seconds and maintained it for several hours. This test involved two of SpaceX's four satellites, which also feature Leidos infrared sensors. The successful exchange is a crucial step in the SDA's Proliferated Warfighter Space Architecture (PWSA) program, aimed at enhancing military communications and surveillance through a network of small satellites. The Tranche 0 deployment includes contributions from SpaceX, Lockheed Martin, York Space, and L3Harris. The SDA's director, Derek Tournear, emphasized the importance of this test, noting that previous attempts did not meet current standards. Additionally, all four satellites have successfully detected rocket launches, including the re-entry of SpaceX's Starship in June.
