U.S. launches yet another secret satellite yesterday

"The fleet of U.S. spy satellites has just welcomed a new member.

The NROL-47 spacecraft soared into Earth orbit today (Jan. 12), riding atop a United Launch Alliance (ULA) Delta IV Medium rocket that lifted off from California's Vandenberg Air Force Base at 5:11 p.m. EST (2211 GMT, 2:11 p.m. local California time).

NROL-47 will be operated by the National Reconnaissance Office (NRO), which builds and manages the United States' spy satellites. NRO missions tend to be hush-hush, and NROL-47 is no exception; no details have been released about the satellite's planned activities. [The Secret NROL-47 Spy Satellite Launch in Photos]"
