For the past several months there has been considerable discussion regarding the question of whether we should perform the lunar orbit insertion (LOI) maneuver as a single burn or if it should be made in two steps. This is an important matter to resolve since it has impact on RTCC program development, guidance systems targeting,…

Reentry from lunar missions
On January 12 a group of Flight Crew, Flight Control and Mission Planning guys got together to talk about the lunar reentry and some rather interesting things came out which I am recording here for my records and your amusement….
C’ Transearth Midcourse Correction (MCC) and Entry Mission Techniques
On September 13, we conducted a review of the Transearth MCC and Entry Mission Techniques for a lunar mission. Although, originally developed for an F or G type mission, the discussion was almost completely devoted to C’. Participation included all interested MSC organizations (including the C’ flight crew) as well as representatives from North American,…
Results of September 17 Apollo Spacecraft Software Configuration Control Board (ASSCCB) meeting
The first three hours of this marathon meeting were devoted to implementation of the descent program in LUMINARY. The currently approved plan is to implement the one-phase descent scheme proposed by Floyd Bennett and his merry crew. However, MIT has been directed to implement it in such a way that it would be possible to…
F Rendezvous Mission Techniques
We had our first F Rendezvous Mission Techniques meeting on November 12. We went through the whole thing rather smoothly with very few open items, probably due to all the past work on D and G. Obviously it is a much simpler exercise than the D rendezvous. This memo is to record a few of…
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…
Some decisions regarding lunar landmark tracking on the F and G missions
We had an Ad Hoc Mission Techniques meeting on January 9 to talk over lunar landmark tracking. In particular, we wanted to discuss what we thought had been learned from the C’ mission and what we want to do on the F and G missions. This memo is to outline all that briefly. The specific…
Operations required for communication loss on F and G are sure better than on C’
I think we have pretty well established how to handle a communication loss situation on the F and G missions. In effect, we have defined which Block data must be sent and what onboard cis-lunar navigation needs to be carried out. In both cases, of course, it is possible to cut back substantially from the…
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….
