Liftoff!
On Sept. 8, 2016, a United Launch Alliance Atlas V rocket carrying NASA's OSIRIS-REx probe took off from Cape Canaveral's Launch Complex 41 just after 7 p.m. EDT (2300 GMT).
The $800 million mission is sending the OSIRIS-REx spacecraft to the asteroid Bennu, with the probe arriving in 2018 and returning samples of the space rock to Earth by 2023. The mission is the first U.S. asteroid sample-return mission. See more photos of the launch in this gallery, including some views of OSIRIS-REx as it was prepared for flight.
OSIRIS-REx Begins
With its successful launch, NASA's OSIRIS-REx begins a seven-year mission to the asteroid Bennu. The probe is due to arrive at the asteroid in 2018, spend two years studying the space rock and collecting samples, then return to Earth in 2023.

Getting Packed For the Trip
In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, engineers and technicians packed the OSIRIS-REx probe into the payload fairing that goes on top of an Atlas V rocket.
