On September 10, NASA’s OSIRIS-REx spacecraft briefly fired its ACS (attitude control system) thrusters to point itself toward Earth, putting it on course to release its sample capsule, carrying rocks and dust from asteroid Bennu, from 63,000 miles (or 102,000 kilometers) above Earth’s surface on Su
to point itself toward Earth, putting it on course to release its sample capsule, carrying rocks and dust from asteroid Bennu, from 63,000 miles above Earth’s surface on Sunday, Sept. 24.
This graphic shows the Earth return trajectory for the OSIRIS-REx spacecraft and for the sample capsule, after the spacecraft releases it above Earth on September 24. The yellow diamonds indicate the dates of spacecraft maneuvers that slightly adjust its trajectory to get it closer, and then pointing at, and then above Earth.
