The OSIRIS-REx spacecraft is scheduled to blast off Thursday at 7:05 pm (2305 GMT) from Cape Canaveral Air Force Station, near the Kennedy Space Center in Florida.
"The primary objective of the mission is to bring back 60 grams (2.1 ounces) of pristine carbon-rich material from the surface of Bennu," said Dante Lauretta, principal investigator of the mission and a professor of planetary science at the University of Arizona.

"We expect these samples will contain organic molecules from the early solar system that may give us information and clues to the origin of life."
The Lockheed Martin-made spacecraft will be carried aboard an Atlas V rocket made by United Launch Alliance, a 50-50 joint venture owned by Lockheed and Boeing.
