‘A Terrific Performance’

“What a terrific performance by the combined Atlas V team,” NASA Launch Manager Tim Dunn told NASA Commentator Mike Curie after the OSIRIS-REx spacecraft separated from the Centaur upper stage, signifying the end of tonight’s launch and the start of the asteroid-sampler’s mission to Bennu.

“Not a single anomaly was worked during the countdown,” Dunn said. “That’s almost unheard of — it’s a launch director’s dream.”

He commended the spacecraft, rocket and launch teams whose thorough preparations led to a very successful countdown and launch, sending OSIRIS-REx off on its mission at the first launch opportunity at 7:05 p.m. tonight.
