The team has received confirmation that OSIRIS-REx's two solar arrays have deployed.
"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 …
Flying high above the southern tip of Australia, the OSIRIS-REx successfully separated from the Centaur upper stage, beginning a seven-year mission to travel to the asteroid Bennu and return a sample to Earth. Next, OSIRIS-REx will "phone home" via the Deep Space Network, and confirm its solar arrays have deployed.
Controllers and mission officials are expecting to see OSIRIS-REx separate from the Centaur in two minutes.
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.
The Centaur's RL-10 engine has cut off for the second and final time. OSIRIS-REx will remain attached for another 15 minutes before it is released at about 8:04 p.m. EDT.
Centaur engine is performing well and tank pressures are stable, according to ULA Telemetry Engineer Marty Malinowski.
The Centaur engine has reignited for its second and final burn in tonight's ascent. This burn lasts six minutes, 50 seconds.

The Centaur and the OSIRIS-REx spacecraft are still joined as they continue in the first coast phase. It's been 26 minutes since the Atlas V rocket carrying OSIRIS-REx lifted off from Space Launch Complex 41. The Atlas V first stage performed well and handed off to the Centaur upper stage, which completed its first of two …
