- Hybrid trajectoryApollo 13 used a hybrid trajectory that launched to a highly elliptical Earth orbit that fell short of the Moon with effectively a free return to the atmospheric entry corridor1. To do this, the service module’s propulsion system provided a 4.6-metre- (15-foot-) per-second velocity change designed to lower the command module’s closest approach to the Moon from 389 km (242 miles) to 109 km (68 miles) and place the craft on a “non-free-return” trajectory2.Learn more:✕This summary was generated using AI based on multiple online sources.

At 30:40:50 into the mission, with the TV camera running, the crew performed a burn to place Apollo 13 on a hybrid trajectory. The departure from a free-return trajectory meant that if no further burns were performed, Apollo 13 would miss Earth on its return trajectory, rather than intercept it, as with a free return.
