The purpose of the rendezvous was to demonstrate the CSM's ability to match orbits with and rescue a LM after an aborted lunar landing attempt, or following liftoff from the lunar surface. This was to occur on the second day; but by the end of the first, Schirra had reported he had a cold, and, despite Slayton coming on the loop to argue in favor, declined Mission Control's request that the crew power up and test the onboard television camera prior to the rendezvous, citing the cold, that the crew had not eaten, and that there was already a very full schedule.
