SpaceX launched another batch of U.S. spy satellites from California's central coast tonight (Jan. 9).
A Falcon 9 rocket lifted off from Vandenberg Space Force Base tonight at 10:53 p.m. EST (7:53 p.m. local California time; 0353 GMT on Jan. 10) on the NROL-153 mission for the U.S. National Reconnaissance Office (NRO).
NROL-153 was the seventh launch servicing the NRO's "proliferated architecture," which the agency has described as consisting of "numerous, smaller satellites designed for capability and resilience."
We don't know much beyond that, as the NRO tends to be tight-lipped about its orbiting assets. However, the proliferated architecture satellites are thought to be "Starshield" craft — modified versions of SpaceX's Starlink internet satellites featuring some high-tech reconnaissance gear.

The previous six proliferated architecture missions also flew on Falcon 9 rockets from Vandenberg, between May and December of last year.
The Falcon 9's first stage came down for a landing on the SpaceX drone ship named "Of Course I Still Love You" in the Pacific Ocean about eight minutes after liftoff tonight as planned.
It was the 22nd launch and landing for this particular booster, according to a SpaceX mission description.
The rocket's upper stage, meanwhile, continued carrying its clandestine satellites to orbit. We don't know when or where exactly they will be deployed; SpaceX's mission description does not provide that information.
