The U.S. Space Force launched its eighth X-37B Orbital Test Vehicle mission on August 21, 2025, from Kennedy Space Center aboard a SpaceX Falcon 9 rocket. The reusable spaceplane will conduct experiments including a quantum inertial navigation sensor designed to enable precise navigation without GPS, and a laser inter-satellite communication terminal to connect with commercial satellite networks in low-Earth orbit. The quantum sensor, developed by Vector Atomic and Honeywell Aerospace under the Defense Innovation Unit, measures atomic rotation and acceleration to support navigation in GPS-denied environments and deep space. The laser communications experiment aims to enhance data transmission speed, security, and resilience by leveraging proliferated satellite networks. The X-37B program, managed by the Air Force Rapid Capabilities Office and the Space Force, has flown since 2010 and serves as a testbed for advanced space technologies. The Falcon 9’s first stage successfully landed at Cape Canaveral after launch. This mission continues the Space Force’s efforts to develop technologies that improve space domain resilience and operational flexibility. (Updated 22 Aug 2025, 23:43 IST; source: link)
