Attached is an MIT memo I thought you should see. It proposes that the MCC update the gyro compensation terms in the spacecraft computers whenever they are detectably wrong. One benefit, of course, is the possibility of eliminating a bunch of IMU alignments. But more important, it keeps the system right….

Mission Techniques Documentation Schedule
Some people have asked me for a schedule of when the various Mission Techniques books will be coming out. I can’t remember who they all were so I’m sending it to everyone. I’ll update it in a couple of months….
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….
Some more trivia for the F mission
With regard to docked DPS burns we should remember that the LUMINARY program used on F is the same as the SUNDANCE program to be used on D, which due to scaling problems or something barely recognizes that the DPS is running when it is at only 10 percent thrust in the docked configuration. Accordingly,…
Spacecraft separation procedures
I blundered into something the other day which is probably none of my business but is interesting, so I thought I would bring your attention to it. Some time before Apollo 10 the trajectory flight controllers assembled a “Cookbook” of spacecraft separation recipes condensed from the myriad of proposals and recommendations that have been floating…
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’….
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…
Let’s have no unscheduled water dumps on the F mission
During a recent Data Selection Missions Technique meeting we were informed that the CSM has some sort of automatic water dump system. It was even rumored that it might be enabled on the F mission while the crew is sleeping during cis-lunar flight. The memo is to inform everyone than an unscheduled water dump can…
