Following NASA’s strict planetary protection protocols, my engineers have placed me in an orbit around Ceres that should remain stable for decades. I’ll continue to circle as a satellite around one of the worlds I studied for so long. That’s no moon. That’s me.

As we fire the engines, we change the orientation of the spacecraft so that the thrust is continuously directed in the optimal direction to maneuver from any orbit to another orbit.
