Live coverage: International Space Station crew lands in Kazakhstan

Finally on the cusp of launching people to the edge of space, Blue Origin plans to use a suborbital test flight of its New Shepard booster and crew capsule Wednesday to rehearse boarding and recovery procedures for future missions with paying passengers.

NASA’s first space-worthy Orion capsule blasted off atop a Delta 4-Heavy booster rocket for a two-orbit, four-hour shakedown cruise in orbit. Liftoff occurred at 7:05 a.m. EST (1205 GMT), with splashdown in the Pacific Ocean at 11:29 a.m. EST (1629 GMT).

The launch of a Russian Earth observation satellite aboard a Soyuz rocket has been rescheduled for Sunday after a countdown Saturday stopped less than 20 seconds before liftoff.
