1. What Is The Farthest Distance Humans Have Traveled From Earth?
The farthest distance humans have traveled from Earth is approximately 248,655 miles (400,171 kilometers). This record was set during the Apollo 13 mission in 1970.
Apollo 13 Launch
During the ill-fated Apollo 13 mission in April 1970, the spacecraft swung around the Moon at an altitude of 158 miles (254 kilometers) above the lunar surface. This trajectory resulted in the crew reaching a maximum distance of 248,655 miles from Earth. This remains the farthest any human has ever traveled.
2. Why Did Apollo 13 Travel So Far?
Apollo 13 traveled so far due to its planned trajectory around the Moon.
2.1 Planned Lunar Orbit
The mission was originally intended to land on the Moon, but an oxygen tank explosion forced the crew to abort the landing. The spacecraft used the Moon’s gravity to slingshot back towards Earth, which resulted in the record-breaking distance.
2.2 Emergency Return Trajectory
The decision to loop around the Moon was made to conserve resources and ensure a safe return to Earth. According to NASA’s mission logs, this trajectory was the most efficient way to bring the astronauts home.
3. What Were The Apollo Missions?
The Apollo missions were a series of spaceflights undertaken by NASA between 1961 and 1972 with the goal of landing humans on the Moon.
3.1 Apollo 11
