Lunar Module 7, the Apollo 13 LM, was intended to land at Fra Mauro. After the explosion on board the CSM, Odyssey, survival depended on using the LM as a lifeboat. The crew transferred into Aquarius as power on Odyssey failed, powering up the LM just in time. At 0842 on Apr 14 the LM's DPS engine was fired on a 30 second burn to put the ship back on a free-return trajectory. Two hours after skimming 252 km above the lunar farside, the DPS reignited (a burn called PC+2) for 4 min 30 sec to accelerate the return, as supplies began to run low. At 1315 on Apr 17 the Service Module was jettisoned, leaving the CM attached to the Lunar Module. This was the only time that this configuration (a Command Module/Lunar Module without a Service Module) ever flew. As the SM moved away, the destruction of the side bay was visible to the astronauts. At 1643 the crew, now back in Odyssey, undocked and let Aquarius fly on to its destruction in Earth's atmosphere. The Ascent and Descent stages remained attached up to reentry.
