What went wrong when Apollo 13 went into space?

During the Apollo 13 mission, an oxygen tank in the service module exploded due to a combination of a design flaw and improper handling of the tank during pre-launch testing. This explosion caused a loss of electrical power and cabin heat, along with a depletion of vital resources. The crew and mission control had to quickly devise a plan to safely return to Earth, relying on the Lunar Module as a lifeboat to conserve resources. Despite the critical situation, the mission ultimately returned the astronauts home safely.
