NASA’s first mission to visit a near-Earth asteroid, the OSIRIS-REx, has executed the first of a series of exercises to slow down the spacecraft’s speed to put it on course for its scheduled arrival at the asteroid Bennu in December.

The spacecraft’s main engine thrusters fired in a braking maneuver designed to slow the spacecraft’s speed relative to Bennu from approximately 491 meters/second to 140 meters/second, NASA said in a statement on Wednesday.

The mission team will continue to examine telemetry and tracking data as they become available and will have more information on the results of the first “Asteroid Approach Manoeuvre” (AAM-1) over the next week, the US space agency added.
