SPS Burn Rules cue card

Apollo 13 Flown "SPS (Service Propulsion System) Burn Rules" Quick Reference Checklist Cue Card Directly from the Personal Collection of Mission Commander James Lovell, with Signed LOA. A 6" x 3.375" (overall) heavyweight printed card, dated March 16, 1970, odd-shaped and with three pieces of Velcro on the verso for mounting on the instrument panel. This card lists procedures for: SPS Burn Rules; SPS Press Lt; Premature Shutdown; and Engine Does Not Shutdown. The SPS engine was used to place the Apollo spacecraft into and out of lunar orbit and to make mid-course corrections between the earth and the moon. When the oxygen tank exploded in the CSM during the Apollo 13 mission, it was suggested to use the powerful SPS engine to execute a direct abort burn causing the spacecraft to come around the front side of the moon and getting back home within a day and a half. The flight controllers ruled out using it, partly because it required more electrical power than was available and partly because no one knew whether the service module had been structurally weakened by the explosion. If it had, an SPS burn might have been dangerous. A great piece of history. Excellent.

Included with this lot is a signed Letter of Certification from Lovell on his company letterhead stating, in full: "I hereby certify that this Apollo 13 SPS Burn Rules Checklist was on board the Apollo 13 spacecraft. It was put on the instrument panel for reference when needed. Apollo 13 perilous flight took off on April 11 and returned safely on April 17, 1970. This placard is from my personal collection of space artifacts and has been in my possession since the mission."
