Apollo Spacecraft Software Configuration Control Board meeting number 32
On October 9 Chris Kraft convened the first Software Configuration Board meeting since June 5 at MIT. We had a real pot full of PCR’s to discuss, some of which were approved for Apollo 13, some for 14, and some were put in a category in which MIT was to continue development to a point…
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…
Cis-lunar state vector updating procedure change
A lot of you won’t care – but I want to make sure that those that need to know, do. It deals with state vector updates from the MCC to the CSM during cis-lunar flight on the G mission….
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…

Apollo spacecraft guidance navigation modes currently planned for AS-503 and AS-504
I am afraid there is a bit of confusion as to what navigation modes are being provided in the AS-503 and AS-504 Apollo spacecraft computer programs. I am sure I have contributed to this confusion myself, and the purpose of this memorandum is to try and clear it all up….
C’ maneuvers – SPS versus RCS crossover
Neil Townsend (EP2) informed me by phone – and will supply written confirmation – that the minimum duration SPS burn for C’ should be no less than 0.5 seconds. We had been assuming something smaller. According to MPAD (Otis Graf, FM7) this makes the crossover point between use of the RCS versus the SPS engine:…
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’….
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…
