Plans to launch a Navy communications satellite aboard an Atlas 5 rocket early Monday have been interrupted by Tropical Storm Erika, an unpredictable cyclone with its sights on Florida.

This collection of photographs shows the Air Force’s Global Positioning System 2F-12 navigation satellite being encapsulated in the United Launch Alliance Atlas 5 nose cone and hoisted atop the rocket for flight on Friday morning.

Veteran Russian commander Oleg Novitskiy, rookie flight engineer Pyotr Dubrov, and NASA astronaut Mark Vande Hei launched into orbit Friday from the Baikonur Cosmodrome in Kazakhstan at 3:42 a.m. EDT (0742 GMT). The crew members rode a Soyuz capsule in pursuit of the International Space Station, where docking occurred at 7:05 a.m. EDT (1105 GMT).
