Attached is a list of action items associated with our work on “D” Rendezvous Mission Techniques. Would you please see that all those assigned to MPAD are covered by proper Task Assignments (I expect that most of them already are). Specifically, items 2, 3, 4, 7, 9, and 11 are probably OMAB’s jobs and item…

Seventh “D” Mission Rendezvous Mission Techniques meeting
At the seventh “D” Mission Rendezvous Mission Techniques meeting on March 25, we spent most of our time discussing activity in the football rendezvous, specifically, under what circumstances and how to abort. It turned out that the same ground rules and techniques probably apply equally well to the pseudo-TPI maneuver halfway through the rendezvous exercise….
D Rendezvous Mission Techniques
The final review of the D Rendezvous Mission Techniques will be held on Wednesday, January 15, starting at 9:00 a.m., in Room 383, Building 4….
DPS Modeling
It might be worthwhile for you or your people to look into the DPS modelling in the RTCC. The “D” mission includes several maneuvers with manual throttling. Improper modeling of these burns may have some effect on the operation, although, offhand I would not think so….
Mission D Maneuver Monitoring Document
Included in the D mission are some special propulsion and guidance system tests. They consist of unique maneuvers which are not discussed in either the Rendezvous or Entry Mission Techniques Documents. They required development of special mission techniques which are documented in the attached book….
D Rendezvous Ground Rules and Working Agreements update
Attached are the ground rules and working agreements updated based on our September 9 Mission Techniques meeting. They reflect the new, simplified D Rendezvous exercise – primarily changes in the football trajectory and the “insertion maneuver” plus a bunch of things we were able to delete. As noted in my last report of this subject,…
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…
Rendezvous maneuver targeting for guidance system backup
During the “D/E” Rendezvous Mission Techniques meeting of April 15, we spent a lot of time discussing the data transmitted from the ground to the spacecraft involving the CSI and CDH maneuvers. This discussion, of course, centered on how the data should be used and led to a tentative conclusion regarding the backup of these…
D Mission LM PGNCS IMU drift checks
This memo is to backup a telephone conversation with Will Fenner. I hope it doesn’t just add confusion but I thought it might be worthwhile to put into writing my latest with regard to the D Mission LM PGNCS IMU alignments and gyro drift checks. I am pretty sure if limits are approached or slightly…
Notes from the MIT program development plan meeting of April 12
A few things came out of our program development plan meeting at MIT on April 12 that might be worth recording for my memory and your information….
