The OSIRIS-REx spacecraft traveled nearly 4 billion miles in 6 years to bring a piece of an ancient asteroid to earth for study.
LITTLETON, Colo. — Scientists with Lockheed MartinThey helped make space engineering history by retrieving a piece of a 4.5-billion-year-old asteroid named Bennu.
It was a punishing descent through the earth’s atmosphere, but a successful landing – a true tribute to its builders. The capsule and the spacecraft,that carried it on a six-year, four-billion mile journey were both built in Colorado. The TAG maneuver was used to collect the asteroid bits in October 2020. OSIRIS-REx fired its thrusters to nudge itself out of orbit around Bennu. It extended the shoulder, then elbow, then wrist of its 11-foot sampling arm, known as the Touch-And-Go Sample Acquisition Mechanism , and transited across Bennu while descending about a half-mile toward the surface.
Crews from Lockheed Martin have been rehearsing for that moment for months. After landing, the probe was flown by helicopter to a remote clean room and prepared for scientific analysis.
