Apollo 13 launch cover with a KSC handcancel postmark.
Launched on April 11, 1970, the mission was soon aborted after an oxygen tank exploded two days later, crippling the Service Module (SM) upon which the Command Module (CM) depended.
"Houston, we've had a problem..." - Swigert and Lovell reported the service module explosion incident at 9:08 pm on Apr 13, 1970.
Ken Mattingly was originally slated to be the Command Module Pilot. Seven days before launch, Charles Duke contracted German measles from one of his children. This exposed both prime and backup crews, who trained together. Mattingly was found to be the only one of the other five who had not had German measles as a child and thus was not immune. Three days before launch, at the insistence of the Flight Surgeon, Swigert was moved to the prime crew. Mattingly never contracted the German measles.

Parkes radio telescope was used during the Apollo 11 mission, but it was not committed to the Apollo 13 mission. When the explosion occurred, Mission Control in Houston needed Parkes to receive weak signals from Apollo 13 and relay them to Houston. The staff at Parkes prepared the telescope for spacecraft reception in less than six hours. NASA’s three Apollo tracking stations in Australia – Honeysuckle Creek, Tidbinbilla and Carnarvon, successfully maintained the link with Apollo 13 but with the addition of Parkes, the control centre received 20% more data from Apollo 13.
Despite great hardship caused by limited power, loss of cabin heat, shortage of potable water, and the critical need to jury-rig the carbon dioxide removal system, the crew returned safely to Earth on April 17.
