OSIRIS-REx makes last course correction before releasing asteroid sample return capsule – Behind The Black – Robert Zimmerman

OSIRIS-REx’s engineers on September 17, 2023 successfully completed the last course correction necessary before releasing the sample return capsule carrying about nine ounces of material from the asteroid Bennu, set to land in Utah on September 24th.

The spacecraft briefly fired its thrusters Sunday to change its velocity by 7 inches per minute (3 millimeters per second) relative to Earth. This final correction maneuver moved the sample capsule’s predicted landing location east by nearly 8 miles, or 12.5 kilometers, to the center of its predetermined landing zone inside a 36-mile by 8.5-mile (58-kilometer by 14-kilometer) area on the Defense Department’s Utah Test and Training Range….
