FLOWN TO THE LUNAR SURFACE ꩵFOR USE IN EMERGENCY DURING APOLLO 11&n♌bsp;

This Apollo 11 LUNAR SUR🐻FACE FLOWN checklist sheet details emergency liftoff procedures in the event ꩵNeil Armstrong and Buzz Aldrin had to curtail their historic mission to the Moon.  

BUZZ ALDRIN’s pr⭕ovenance letter reads:  

“Accompanying this letter is a tinted sheet numbered SUR-65 and SUR-66 from the Apollo 11 LM Lunar Surface Checklist, Part No. SKB32100074-363, S/N 1001. The checklist was carried to the Moon on the flight of Apollo 11 during July 16 to 24, 1969. Then the entire checklist, including this sheet, was carried to the surface of the Moon in Lunar Module Eagle ♑during the first lunar landing on July 20, 1969. This sheet lists procedures for one of the most difficult emergency conditions that could occur on the Moon – EMERGENCY LIFT-OFF.  

If conditions arose where Neil Armstrong and I had to make an immediate lift-off from the Moon, we would have referred to this sheet. SUR-65 advises if time permitted, that we don our space suit helmets and gloves. We would then configure our ascent batteries, set various water and oxygen values, then close all circuit breakers except for the ones listed. Next we would run a P27 which was a computer program to revise our lunar lift-off time and then activate our AGS or Abort Guidance Section of our navigation system. The final steps were to al🍨ign our PGNS or Primary Guidance and Navigation Section with the landing site coordinates, current mission time, and our Reference Stable Member Matrix (REFSM𝔉MAT) and Gravity values.  

Side SUR-66 lists additional steps required for an emergency lift-off such as computer inputs of our Inertial portion of the Coupli꧟ng Data Unit (ICDU) angles. Then we would initialize our AGS with a series of computer verb commands and noun values. Needless to say, these were all a very complicated series of steps Neil and I would have performed in order to safely leave the lunar surface Fortunately, we did not have to implement these procedures. Events after our lunar landing were all successful, including an over 2 hour lunar surface exploration period during July 20 and 21, 1969.  

The complete checklist for lunar surface activities was a vital document to the success of our mission. It provided information on steps requi🍌red to operate equipment associated with the fওirst lunar landing.  

This sheet has been in my private collection since 1969. I have written on side SUR-65: ‘Carried in Eagle to the Lunar Surface’ and signed it along the right side. I have also written on SUR-66 ‘Carried in Eagle to the Lunar Surface on Apollo XI’ and signed it🅠 al𝓡ong the right side. BUZZ ALDRIN.”
