(2-18-69) After yesterday’s meeting/on the F mission, I have had some second thoughts and prompting by others about using the spacecraft guidance and platform for S-IVB TLI. The following summarizes my position and is to be used as policy in FOD….

F Mission Techniques – LM Checkout
On December 6 we had our first F Mission Techniques meeting dealing with pre-DOI activity. It resulted in a lot of things I never expected, since I thought the timeline and procedures for LM checkout and CSM landing site tracking were pretty well organized and acceptable with just minor tune-up. At this meeting we really…
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…
The LM4 RR/LGC interface may be broken, but that’s okay – sorta
This memo is to document the Data Priority position regarding a recent LM4 systems problem. To wit, it is considered acceptable to proceed with the nominal F mission with a questionable or known interface failure between the rendezvous radar (RR) and the LM spacecraft computer (LGC). It should be emphasized that a properly operating rendezvous…
CSM rendezvous navigation works fine using just VHF ranging
I made an announcement during the F Operations Review which was absolutely flat-out wrong. This memo is to correct that statement and/or just to make sure you know what capability really exists in the CSM for rendezvous navigation….
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:…
F/G Mirror Image Targeting shall use a three-minute delay
As you know, we have established as a standard procedure during Apollo rendezvous having CSM backup LM maneuvers in order to retain the nominal relative motion during this critical mission phase. On the D mission these “mirror image” CSM maneuvers are targeted with TIG delayed one minute after the LM TIG. One minute was chosen…
F/G Rendezvous Mission Techniques – mostly F
As part of F/G Torture Week, we spent Thursday, January 30 on the rendezvous. Overall, I would say this mission phase is in pretty good shape with only a few unresolved items that we know about right now. I would like to tabulate here a bunch of odds and ends we agreed to at this…
F Rendezvous Mission Techniques Clean-up
On April 5 we had what I expect is the last of the F Mission Rendezvous Techniques meetings. We resolved a number of open items which had not been covered before, or which popped up during simulations. This memo is to list them for the record. Some are trivial, some are really quite significant….
