Space.com reports that "a huge satellite blasted off Tuesday night in a dazzling launch for a mission to help improve the U.S. military's tactical communications capabilities."
"The U.S. Navy's Mobile User Objective System-3 satellite, or MUOS-3, streaked into orbit during a spectacular night launch of an Atlas V rocket from Florida's Cape Canaveral Air Force Station at 8:04 p.m. EST (0104 GMT on Jan. 21). MUOS-3 will eventually maneuver to geosynchronous orbit, about 22,000 miles (35,400 kilometers) above Earth."
"As its name suggests, the 7.5-ton (6,800 kilograms) MUOS-3 is the third Mobile User Objective System spacecraft to reach orbit. MUOS-1 and MUOS-2 launched in February 2012 and July 2013, respectively, also atop Atlas V rockets."
