Farthest distance from Earth traveled by humans

In April 1970, the crew of NASA’s Apollo 13 mission achieved the farthest distance from Earth ever reached by humans during their journey around the Moon. On 15/04/1970, astronauts James A. Lovell Jr., Fred W. Haise Jr., and John L. “Jack” Swigert Jr. reached a maximum distance of approximately 400,171 kilometers (248,655 miles) from Earth while traveling along a free-return trajectory. Apollo 13 was launched on 11/04/1970 with the objective of landing on the Moon. However, on 13/04/1970, an oxygen tank in the service module exploded, causing a major in-flight emergency and forcing the crew to abandon their planned lunar landing. Mission control redirected the spacecraft onto a free-return trajectory, a path that would loop around the Moon and naturally bring the crew back toward Earth without requiring major propulsion. As the spacecraft passed behind the Moon, the crew reached their maximum distance from Earth, setting a record that remains unmatched. During this phase, they operated under limited power and life-support conditions, using the lunar module as a lifeboat. The trajectory ensured that despite the failure, the spacecraft would continue its path back to Earth. Apollo 13 safely returned on 17/04/1970, with the crew splashing down in the Pacific Ocean. Although the mission did not achieve its original goal, it demonstrated the effectiveness of mission planning, spacecraft design, and ground support in handling critical situations during deep-space travel.
