‘A Night for Celebration’

Liftoff of the Atlas V carrying NASA's OSIRIS-REx spacecraftNASA’s first asteroid sampling mission launched into space at 7:05 p.m. EDT Thursday from Cape Canaveral Air Force Station in Florida, beginning a journey that could revolutionize our understanding of the early solar system.

A United Launch Alliance Atlas V boosted NASA’s OSIRIS-REx spacecraft, short for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer, onto a path to the asteroid Bennu. Shortly after the spacecraft separated from the launch vehicle, controllers on the ground received welcome news from orbit: the spacecraft’s solar panels had deployed and it was healthy.

“The OSIRIS-REx spacecraft is happy and healthy,” said Rich Kuhns, OSIRIS-REx program manager for Lockheed Martin Space Systems in Denver. “We started the journey with a phenomenal launch on the Atlas V, it delivered us right where we needed to be, separated where we said we would – and since then, it’s been knocking out milestone after milestone.”

“Tonight is a night for celebration – we are on the way to an asteroid,” said Ellen Stofan, NASA’s chief scientist. “We’re going to be answering some of the most fundamental questions that NASA works on.”

OSIRIS-REx Powered Up, Communicating

OSIRIS REx’s solar arrays are providing power and the spacecraft is communicating with controllers on Earth, according to Geoffrey Yoder, acting associate administrator of NASA’s Science Mission Directorate in Washington.

“Everything is working thus far,” Yoder reported. “It’s a great day for the space program.”

This concludes live countdown coverage, but stay tuned to NASA TV for a post-launch news conference scheduled for 9 p.m. at NASA’s Kennedy Space Center in Florida.

‘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.

Second Coast Phase Continues

The OSIRIS-REx spacecraft remains attached to the Centaur upper stage following the ride to space that began with liftoff from Space Launch Complex 41 in Florida at 7:05 p.m. EDT. The spacecraft is due to separate from the Centaur at about 8:04 p.m.
