On Aug. 14, 2017, a SpaceX Dragon spacecraft was launched atop a Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center. It was a commercial resupply mission delivering supplies to the International Space Station. Four days later, the agency’s Tracking and Data Relay Satellite-M lifted off on a United Launch Alliance (ULA) Atlas V from Space Launch Complex 41 at Cape Canaveral Space Force Station.
