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…

C’ Mission Techniques – mostly Entry
On Friday, November 15, we had the last C’ Mission Techniques meeting I expect we will ever have. It was mostly devoted to entry although, of course, some other odds and ends were discussed….
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…
Proposal to add something nice to the F mission
If it makes sense, I would like to start a campaign to add some actual powered descent into the F mission with an abort about 300 seconds after PDI or whenever it is that the DPS can return the LM to the desired orbit. Could you people please give me a list of the benefits…
Progress Report on Mission Techniques
Since we have not been able to get together this year, except for our short discussion prior to the George Mueller briefing, I thought it might be a good idea to send you a little informal Mission Techniques progress report. I guess our lack of contact is an implicit vote of confidence which I hope…
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:…
July 19 “C” Rendezvous Mission Techniques meeting
Although most of the things discussed in our Friday, July 19 “C” Rendezvous Mission Techniques meeting are not of general interest, there were a couple of things I would like to let you know about….
List of “D/E” Rendezvous open items
On April 8, we had our first weekly “D/E” Rendezvous Mission Techniques meeting. We spent the whole time going through the main flow charts. This memorandum is not really minutes of the meeting, but rather a list of questions and action items. We are assuming that both the “D” and “E” missions will utilize the…
Status evaluation meeting – “C” Mission Rendezvous
As most of you are probably aware, we have a special “C” Mission Rendezvous meeting scheduled for April 22, starting at 9:00am in room 966 of Building 2. This memorandum is to define its purpose as I understand it. It is also to inform you that another somewhat related meeting which had been scheduled or…
