ARMSTONG AND CREW RETURNING HOME.
ALDRIN REFLECTS ON MISSION.
Flown Apollo 11 Flight Plan sheet, page 3-113/3-114, a single sheet printed recto and verso. NASA/MSC, July 1, 1969. 8 x 10½ inches. Extensive notations by Neil Armstrong. With a Typed Letter Signed by BUZZ ALDRIN.
BUZZ ALDRIN'S signed provenance letter reads in part: "Enclosed with this letter is a sheet numbered 3-113 and 3-114 from the Apollo 11 Flight Plan, Part No. SKB32100080-350, S/N 1001. It is part of the entire document that was carried to the Moon in Command Module Columbia on the first lunar landing mission during July 16 to 24, 1969. This sheet is from the detailed timeline section and covers from hour 157 to the beginning of hour 161 in the mission.
The previous day, July 21, Neil Armstrong and I had left the lunar surface after an approximately 22 hour stay and surface excursion. Once we completed rendezvous, we started preparations to return home to Earth. Our Transearth Injection (TEI) engine burn had to work. If it did not, Neil, Michael Collins, and myself would remain in lunar orbit, never to return.
The TEI burn did work and we were able to get several hours rest afterwards. At about 147 hours into the mission, Mission Control gave us a wake-up call. After the post sleep activities, we prepared for and completed the MCC5 (Mid Course Correction) burn number 5 to refine our trajectory back to Earth. The burn accomplished exactly what we and Mission Control wanted, a precise placement to our entry corridor into the Earth's atmosphere. We had some open time as noted on page 3-113. We had just completed a television transmission to viewers on Earth and were beginning to get set for our upcoming sleep period. Neil Armstrong marked through and checked off the steps associated with our hatch tunnel and logged that we changed out a carbon dioxide filter at '159:31' in the mission. We did have a chance to reflect on the accomplishments of the past few days - making the first lunar landing, the first lunar surface excursion, lift-off from the Moon, the lunar orbit rendezvous, and the start of our return home.
Page 3-114 shows we were having our evening meal plus preps for our sleep period. Neil Armstrong recorded our radiation exposure of: 'CDR - 11020, CMP - 10022, LMP - 09024' and logged in the On Board Readout box: '37.0 --->, 51, 63, 63, 59.' The first three numbers, all the same, were the battery values and the last four were Reaction Control System values. Neil then checked off over ten steps in our Presleep Checklist. We had clearly circled and pointed to the EMS CK (Entry Monitor System) check out. We did this prior to the sleep period and Neil wrote: 'O. K. (0.1)' and checked it complete. This system would be used during our reentry into the earth's atmosphere....
This page has been in my private collection since 1969. I have written on page 3-113: 'Flown to the Moon' and signed that page. I have also written on page 3-114: 'Carried to the Moon on Apollo XI' and signed my name along the bottom of that page."
Additionally, a copy of the flight plan cover is enclosed.
