Earth reflection in the window of the lifeboat LM Aquarius during the critical undocking from the Command Module Odyssey, 11-17 April 1970

Due to the unusual spacecraft configuration resulting from retaining the LM, entry procedures had to be modified. First came the separation of the damaged Service Module. Then the Command Module Odyssey was powered up and the crew transferred back to the CM. The LM was then undocked. (http://www.lpi.usra.edu/lunar/missions/apollo/apollo_13/)

“A most remarkable achievement of Mission Control was quickly developing procedures for powering up the CM after its long cold sleep. They wrote the documents for this innovation in three days, instead of the usual three months. We found the CM a cold, clammy tin can when we started to power up. The walls, ceiling, floor, wire harnesses, and panels were all covered with droplets of water. We suspected conditions were the same behind the panels. The chances of short circuits caused us apprehension, to say the least. But thanks to the safeguards built into the Command Module after the disastrous fire in January 1967, no arcing took place. The droplets furnished one sensation as we decelerated in the atmosphere: it rained inside the CM.”
