Live coverage: Atlas 5 blasts off with Navy satellite

United Launch Alliance’s final Delta 2 rocket is now on display at the Kennedy Space Center Visitor Complex in Florida, a monument to an industry workhorse that helped build the GPS navigation satellite fleet and enabled a new era of Mars exploration.

An 11-hour practice countdown was completed Friday at Cape Canaveral’s launch complex 41 for the planned launch of an Atlas 5 rocket and Boeing’s Starliner capsule later this month. The rocket was loaded with super-cold liquid oxygen and liquid hydrogen in a full dress rehearsal for launch day.
