Video: Weather causes Atlas 5 countdown hold

At NASA’s Kennedy Space Center, workers have finished the pre-launch assembly and fueling of OSIRIS-REx for the asteroid sample return spacecraft for liftoff Sept. 8.

Poised to embark on a 7-year adventure to Asteroid Bennu and back, NASA’s OSIRIS-REx sample return spacecraft was moved to the launch pad today aboard its Atlas 5 rocket for liftoff Thursday evening.

Air Force meteorologists are giving good odds of acceptable weather conditions for the United Launch Alliance Atlas 5 rocket to fly Friday morning from Cape Canaveral to put a Navy mobile communications satellite into orbit.
