On October 4 we met to review a draft of the D Rendezvous Mission Techniques. Although we spent the entire day we didn’t get past page 3 and so it is obvious we are going to have to beef up our effort in order to get all this cleaned up. In fact, I am going…

It’s SUNDISK for Spacecraft 103
This memo is to make absolutely sure you are aware of the horrible decision we had to make, namely that we must use the SUNDISK spacecraft computer program for Command Module 103 as well as 101. Of course, I am bringing this to your special attention since it has obvious influence on how the Apollo…
“D” Rendezvous
A great many things were discussed and resolved at the July 22 “D” Rendezvous Mission Techniques meeting. They will all be fully recorded in the minutes. There were three items, however, I would like to call particular attention to at this time by this memo….
Comparison limits for rendezvous radar test on Apollo 9
Reference: Shannahan, Philip: Rendezvous radar checkout for Apollo 9, OMAB Memorandum 69-FM62-38, Feb. 20, 1969….
D Maneuver Monitoring Mission Techniques
On November 4 we had our first-and-last D Maneuver Monitoring Mission Techniques meeting. In addition to all interested MSC organizations, it was attended by MIT, NR, TRW, and GAEC. We spent the day going through all of the SPS maneuvers both docked and undocked, except for those associated with the rendezvous and the docked DPS…
AGS accelerometers may not work.
Apparently, there is a basic problem in the LM Abort Guidance System (AGS). Although it is not widely known, there is a rumor the accelerometers do not work and it is highly likely G&C Division will elect to procure the AGS accelerometers from another source. Since it is too late to obtain and incorporate them…
Apparently, S/C 103 may fly one month after S/C 101
At his staff meeting on Monday, George Low made a strong point about uncoupling Spacecraft 101 and Spacecraft 103. Apparently, he feels it is likely that 103 will be launched on a Saturn 5 which implies no pad readiness schedule implications. The LM-2 will be available at the Cape early and, apparently, Spacecraft 103 is…
Comments on the AS-207/208 Preliminary Spacecraft Reference Trajectory
TRW Systems released the AS-207/208 Preliminary Spacecraft Reference Trajectory during the first week of May. This report was put together on a compressed schedule, starting from rather hastily defined mission requirements. As a result, there are a number of things about it which were recognized as being in error even before release; however, since we…
Progress Report on Mission Techniques
Since we have not been able to get together this year, except for our short discussion prior to the George Mueller briefing, I thought it might be a good idea to send you a little informal Mission Techniques progress report. I guess our lack of contact is an implicit vote of confidence which I hope…
List of “D/E” Rendezvous open items
On April 8, we had our first weekly “D/E” Rendezvous Mission Techniques meeting. We spent the whole time going through the main flow charts. This memorandum is not really minutes of the meeting, but rather a list of questions and action items. We are assuming that both the “D” and “E” missions will utilize the…
