During our March 27 Lunar Surface Mission Techniques meeting I think we finally settled how we think the PGNCS should be operated. How many times have I said that before? This memo is to broadcast a few new items that might be of general interest….

Some G Mission Techniques action items
This memo is just a list of action items assigned to MPAD and/or MIT which I remember coming from our recent G descent/descent abort meetings. In addition to reminding those responsible for them, they serve as some sort of indication of what’s going on in this business which you might find interesting….
RLS Determination
On April 2 we had a Mission Techniques meeting to discuss how we should handle the determination of the LMs position on the lunar surface (RLS). Specifically, we were concerned with how to determine its values and, after improved values are determined, when they should be loaded into the spacecraft computer. One obvious conclusion, if…
AGS alignments in lunar orbit and operations on the lunar surface
On April 2 we finally got around to establishing how to operate the AGS on the lunar landing mission. The two basic subjects for discussion were how to handle CDU transient problems when aligning the AGS to the PGNCS in lunar orbit and how to operate the AGS in total while on the lunar surface….
Some things about Ascent from the moon
On April 3 we had an Ascent Mission Techniques meeting – the first in a long time. This memo is mostly to express some rather general observations….
Descent monitoring at MCC
We have reached a plateau in our work on Descent Monitoring, perhaps making it worthwhile to send out this memo. First of all, I don’t think there is any question that Descent is the thing that requires most of our attention between now and the G mission, at least in the empire of Mission Techniques….
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….
Some things about Descent
This memo is to list a few odds and ends dribbling out of our latest Descent Monitoring clambake….
Let’s drop one of the lunar surface RR tests
During our review of the G Mission Lunar Surface Mission Techniques Document on April 10, we came to a conclusion which may interest you. It deals with the need, or really lack of need, for the crew to do some things that are in the current flight plan. Specifically, in the crew LM timeline, we…
How the MSFN and sextant data are used to target DOI and Descent
We had a meeting on April 9 which was extremely interesting to me. We discussed and settled on how the MSFN tracking and sextant landmark observations would be used in the MCC/RTCC to produce optimum DOI and Descent targeting for the LM. The big new factor that had to be taken into account somehow was…
