This note is in follow-up to our “D” mission launch window discussion during our Tuesday morning meeting. Essentially, the situation is as I understood it to be at that time. Real time procedures can be and are being established to provide a launch window about two and threequarters hours long by using the earlier propulsion…

Rendezvous meeting reminder
This note is to remind you of our Rendezvous meetings on January 3, 1968. In the morning we hope to discuss Rendezvous on the “C” mission starting at 9:00 a.m. and in the afternoon Rendezvous on the “D” mission starting about 1:00pm….
D Rendezvous Open Items, Action Items or whatever you call them
I’ve reviewed my notes of the D Rendezvous meetings over the last couple of months and have found the following open/action items. I guess most, if not all, are being worked on. But time grows short and so I’m sending this list around to make sure of it. If you know of others, please give…
“C” Rendezvous Mission Techniques Review
Attached is a preliminary version of the “C” Rendezvous Mission Techniques document. It is based on numerous meetings of a MSC working group involving Flight Controller Directorate, Flight Crew Directorate, and Engineering and Development Directorate people and their contractors. Although there are still known flaws and more open items, we have reached a point where…
Propulsion system to be used on the “D” Mission Rendezvous CSI Maneuver
One of the planned rendezvous maneuvers (CSI₁) on the “D” mission is nominally zero. Since it is intended to make this maneuver based on the real time situation, some logic must be established to govern when and how the maneuver would be made. This memo is to describe the proposed logic….
D Rendezvous Mission Techniques Meeting – September 9, 1968
On September 9, we had another D Rendezvous Mission Techniques meeting. Basically what we did there was to discuss the new, simplified rendezvous mission plan and its effect on the work we have done so far. Based on this discussion, I am revising the ground rules and working agreements and will send them out within…

At the June 14 “D” Rendezvous Mission Techniques meeting, I unofficially (I guess) assigned at action item to your people who were there. Specifically, we asked for MIT’s recommended procedure for adjusting the W-matrix during rendezvous navigation in both the LGC and CMC. As a matter of fact, I understand that your people intend to…
D Rendezvous Mission Techniques
This memo is to tell you about the results of the November 25 D Rendezvous Mission Techniques meeting. Except for a number of small clean up items, we spent most of our time talking about how to handle slippage of TPI time and incomplete Insertion and Phasing maneuvers. After an exhausting discussion, I think we…
D Rendezvous Mission Techniques
This memo is to let you know about some things on the D Rendezvous that have been giving us a lot of trouble. The problem we have been having is associated with the football trajectory and how to exit from it gracefully. It seems like most of the significant mission techniques open items deal with…
“D” Rendezvous Mission Techniques Task Assignments for MPAD
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…
