This may seem like a trivial matter – however, before any confusion arises let’s firmly establish the means of identifying revolutions in lunar orbit by number. Specifically, unless there’s some good reason for choosing another way:…

C’ Mission Techniques
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…
Data Priority meetings schedule
In order to get a little bit more orderly in our conduct of the Trajectory Control Data Priority business, it’s evident that we must schedule meetings on a pre-established, periodic basis. Accordingly, the Ascent and Descent meetings will take place on alternate Tuesday afternoons; Rendezvous meetings will be held of Wednesdays, one mission in the…
Crew monitoring of the LOI maneuver
On August 3 we had an informal meeting to talk about crew monitoring of the Lunar Orbit Insertion (LOI) maneuver. The subject came up in connection with Jim McDivitt’s preparation for the STAC presentation. I’m writing this note because we tentatively agreed on some fairly basic points with regard to how we might use the…
Notice of a catch-all Apollo 12 Mission Techniques meeting
We have scheduled a Mission Techniques meeting on Monday, September 15, 1969, to go over the Apollo 12 flight for the “last” time. Although most of the discussion will probably deal with the landing and rendezvous phases, we would like to clean up all open items regardless of mission phase….
Recommendation to retain the Two-Stage Lunar Orbit Insertion (LOI) Maneuver
This memorandum documents the results of our review of the two-stage LOI maneuver which you requested as a result of a recent OMSF suggestion that it might be preferable to return to a single burn plan. Participation in this review involved all operational elements of MSC concerned in this matter. The conclusions are unanimous….
External Delta V for LOI
In a December 15 memo (67-PA-T-121A), I indicated that we were going to perform LOI using two maneuvers. I also stated that pending results of some studies then underway we expected to use the External Delta V guidance mode for these maneuvers rather than Lambert steering. The primary reason for doing this was to make…
F and G cis-lunar midcourse correction scheduling
This memo is to make sure everyone is aware that we are scheduling the final midcourse corrections before LOS and Entry differently than on C’….
F and G Lunar Orbital operations – mostly pre-DOI LM activation stuff
On January 10 we had an F and G Mission Techniques meeting dealing mostly with Lunar Orbital operations, which I would like to record with this thing….
Apollo Mission Techniques Documentation Schedule
Here is another Mission Techniques Documentation Schedule, since the last one is three months old and barely reflects real life any more. The Lunar Orbit Activities Document will almost certainly have to be updated to reflect whatever we learn on the F mission. A June 30 release date for that update will be kinda late,…
