A United Launch Alliance (ULA) Atlas V rocket launches the SILENTBARKER/NROL-107 mission, a joint National Reconnaissance Office (NRO) and U.S. Space Force (USSF) capability to improve space domain awareness.
In plain terms, it will form a watchdog type of satellite formation to search for and monitor threats from other countries, able to track objects as small as a basketball, watching their position and movement. The payload this rocket carried was heavy enough to demand ULA's most powerful engine configuration, the Atlas V 551. It was a sight to behold from the Gantry, a mere 2.3 miles from the launch pad site.
