The video explains Orion's mission to enter a distant retrograde orbit (DRO) around the moon. The spacecraft approaches 60 miles above the moon's surface, and mission controllers fire the service module's engines to achieve the desired orbit. Orion travels for five days to reach the orbit, which is 40,000 miles beyond the moon. Once in DRO, Orion orbits the moon in the opposite direction of the moon's orbit around Earth. This stable orbit allows Orion to remain for six days before returning to Earth.
