Attached are a list of ground rules and working agreements I compiled from my notes taken at the September 13 and 14 Mission Techniques meetings and the September 20 Lunar Abort meeting, all on the C’ mission. This list is far from complete. Basically, these items are only the changes and additions to the material…

C’ Contingency Review
We went through the draft of the C’ Contingency Mission Techniques document on October 22, and I must say I was impressed with its quality. It seemed to me the Flight Analysis Branch, the Apollo Abort Working Group, and TRW had done a good job of putting this together. The final version will be distributed…
Cis-lunar spacecraft navigation for C’
We are still thrashing around trying to figure out what to do with regard to cis-lunar spacecraft navigation for the C’ mission. It is not clear whether a couple of things are really necessary or not. If we could get rid of them, it would simplify things. Unfortunately, we aren’t confident it is safe to…
Use of DPS for lunar mission aborts
The other day Carl Huss and some of the flight Analysis Branch people gave an internal briefing on Apollo aborting procedures for the lunar landing mission starting with the translunar injection (TLI) maneuver. One thing that impressed me was the large number of situations in which dependence is given to using the Descent Propulsion System…
C’ Mission Techniques clean up – Translunar and Transearth
On November 8 we went over the Translunar and Transearth phases of the C’ Mission Techniques – pretty well cleaning all this up, I think. The following paragraphs describe the more significant decisions and agreements reached. They deal with block data, onboard navigation, and returnto-earth with no communications….
C’ Spacecraft Navigation Mission Techniques
It appears we have completed basic development of C’ Spacecraft Navigation Mission Techniques both for Cis-Lunar and Lunar Orbit. Documentation of these techniques will be distributed in the near future. No further meetings will be called specifically for their subjects. Whatever open items come up will be handled in our weekly C’ Mission Techniques Reviews,…
F and G mission cis-lunar and abort plan
On January 8 a gang of us FOD types got together to develop a proposal on how we should use the LM for cis-lunar and lunar orbit aborts. In other words, how should the C’ techniques be modified due to having the LM DPS available to backup or use in place of the SPS. A…
F/G cis-lunar midcourse correction mission techniques
This memo is to document the cis-lunar midcourse correction mission techniques we agreed to January 27 and 28 at the F and G Mission Techniques meetings. The translunar maneuvers are based on the following assumptions and guidelines:…
Guidance system oriented ground rules for TLI Go/No Go
This memo is to document the guidance system oriented ground rules we intend to apply in the development of mission techniques for making the Translunar Injection (TLI) Go/No Go decision, unless directed otherwise. Effective immediately, it is intended that all RTCC computer programs, MCC displays and decision limit lines, crew and ground procedures and timelines,…
