Read the passage from The Race to Space:
Countdown to Liftoff
So instead of turning around, NASA decided to
continue to the moon, take one orbit around it, and then
use the gravity from the moon to "slingshot" 13 back to
Earth. This would take longer, which was bad because
the astronauts had limited food and water, but it
would use less power and fuel and give 13 the best
chance of getting back.
