How far did the Artemis II crew travel from Earth compared to Apollo 13?

The Artemis II crew traveled approximately 268,554 miles (432,194 kilometers) from Earth, surpassing Apollo 13's previous record of 248,655 miles (400,171 kilometers) set in 1970. This new distance record was achieved during the Artemis II mission's lunar flyby trajectory, which took the Orion spacecraft beyond the Moon's orbit into a distant retrograde orbit (DRO). Unlike Apollo missions that followed free-return trajectories around the Moon, Artemis II's path was specifically designed to test spacecraft systems in deep space environments while maintaining communication with Earth. The increased distance demonstrates advancements in navigation, life support, and radiation protection technologies that enable longer-duration missions. This milestone is crucial for NASA's Artemis program, which aims to establish sustainable lunar exploration and eventually send humans to Mars, requiring capabilities to operate farther from Earth than ever before.
