A number of people who know about the rendezvous radar (Myron Kayton, Richard Broderick, etc.) came to our little Lunar Rendezvous Mission Techniques meeting October 2 and assuaged our anxieties regarding the possibility of poor shaft angle measurements when the line-of-sight to the command module passes close to the lunar horizon. According to the data…

Lunar orbit revolution counter for C’
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’ Lunar Orbit – Navigation and Block Data
On Thursday, November 7, we gathered with the C’ Flight Crew and everyone else who was interested in the lunar orbit Operations On that flight. At this meeting we cleaned up a lot of loose ends primarily dealing with the lunar orbit navigation and with block data. This memo is to report the new things…
Odds and ends about lunar landmark tracking
This memo is just to pass on some numbers which I found interesting when reviewing the lunar landmark orbit determination procedures. It is not intended as an argument “for” or “against” using landmark tracking by the command module for navigation….
F mission lunar orbit attitude sequence
This belated memo is to describe the results of our March 10 Mission Techniques meeting on the F mission lunar orbit attitude sequences as well as I can remember them….
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…
Spacecraft computer program orbital integration
This is just another little golden nugget for your files….
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….
CSM Rescue Mission Techniques are complete and clean
On June 9 we had our final Mission Techniques meeting on CSM Rescue. I am pleased to report that this stuff appears to be in very good shape. After much hard work by many people, the CSM rescue rendezvous plans shake down to only two basic profiles. Each of these has minor modifications to account…
No real time landing site data processing is planned on C Prime
In a meeting with Flight Software Branch and Flight Control Division personnel, we concluded that we would not process landing site observations obtained in lunar orbit on the C’ in real time in the RTCC unless directed otherwise….
