USAF's X-37B Minishuttle Returns to Space on Atlas 5

摘要

After being delayed a day by bad weather, the U.S. Air Force's second X-37B robotic space plane blasted off from Florida March 5 on a classified mission. The unmanned X-37B minishuttle - known as Orbital Test Vehicle 2 (OTV-2) - lifted off from Cape Canaveral at 5:46 p.m. EST atop a United Launch Alliance Atlas 5 rocket. The space plane was originally scheduled to launch March 4, but cloudy, windy conditions scrubbed two attempts.
