This note is to inform everyone that the AS-502 spacecraft computer program ropes will be made precisely the same as those for AS-501. Specifically, it is MIT assembly Solarium 55. You recall Solarium 54 was our original AS-501 A-release, but it was necessary to make a modification in one of the rope modules to correct…

Uplink will be on LM-4
A decision was made yesterday which I am sure will make a lot of people happy. ASPO has finally decided to equip the LM-4 with a digital uplink. Obviously, the associated computer programs must be added to the AS-504 LM program. I assume that these are the same as those developed for AS-208 and should…
Procedures needed for the AS-503 TLI maneuver
This note is to back up our telephone conversation (2/5/67) in which I requested you to prepare our recommendation as to how the AGC should be used during the simulated translunar injection maneuver on AS-503. It’s certain the crew will want to monitor the progress of this large SIVB maneuver, even though it’s controlled by…
No special spacecraft computer programs are to be developed for AS-208B and AS-503
The decision has bean made by the Apollo Program Manager that unique computer programs need not be developed for missions AS-208B (LM) and AS-503 (CM). This decision was brought about due to concern that effort on these programs would affect development of the main line programs. It is certainly consistent with numerous other actions taken…
Significant modifications currently planned in the Apollo Spacecraft Computer Programs
Quite a number of decisions have been obtained from the Apollo Program Manager affecting the development of the AS-258 and AS-504 spacecraft computer programs which I am recording here for my own later reference. As usual, I will send it along to you on the chance that you might be interested….
AS-504 Spacecraft Computer Programs will be able to support earth orbital and lunar missions
At one time I had sort of expected that we would have to maintain two basic programs for each of the Apollo spacecraft – one for earth orbital operations and one for lunar operations. The former would probably be a refinement of the AS-258 programs and the latter of the AS-504 programs. Further investigation, primarily…
Why is it everyone who loves radar wears a white hat?
In one of these notes eight or ten months ago, I commented that it seems to me the Apollo command module really does not have an operational rendezvous capability. In response to that, I was told to “think positive” and that’s what I’m doing for main line Apollo. However, it would be unfortunate if we…
State vector update situation for AS-501 and AS-502
The AS-501 and 502 missions have been designed to update the state vector (position and velocity) in the Apollo Guidance Computer (AGC) with a state vector from the Manned Spaceflight Tracking Network (MSFN) prior to the Saturn (S-IVB) out-of-orbit burn and again prior to the second Spacecraft Propulsion System (SPS) burn. If these updates are…
Justification for SCAMA circuit to MIT/Boston
This memorandum is to provide justification for the addition of a SCAMA circuit between Houston and MIT/Boston and two additional telephones in Building 30, MSC….
Latest on the AS-206 spacecraft computer program
During the January 11 program development plan meeting at MIT, a couple of things came up regarding the AS-206 program that are probably worth recording here….
