One of the possible actions which has been identified to help our spacecraft computer program development schedule is to fly the AS-503 mission with the AS-278 programs. I have indicated in previous memoranda that in order to do this we would probably have to add several routines to the AS-278 program to make it applicable…

More on Program Development
On October 5th, we had the second of our weekly all day program development plan meetings at MIT. Most of our attention was given to the open items on the AS-278 program which I will discuss later, but first I would like to pass on some general comments regarding the work at MIT. Based on…
LGC program requirements and mission constraints on alternate mission AS-278B
Following our AS-206 spacecraft computer program status review at MIT pm October 6th, we launched into a discussion of the AS-278B mission and its demands on the guidance system. This alternate mission, you recall, is one in which the LM and command module are launched separately followed by a CSM active rendezvous. The LM would…
Rendezvous terminal phase guidance program in the Apollo spacecraft computer
On July 7, 1966, a team of MSC and MIT “experts in rendezvous” (including Paul Kramer, Ed Lineberry, John Dablen, and Norm Sears) met at MIT to discuss and review the preliminary Guidance System Operation Plan (GSOP)which MIT has unofficially distributed, covering the terminal phase and External ΔV programs for the AS-207/208 mission. This meeting…
Automatic rendezvous braking maneuver
As you know, MIT is currently designing the command module and lunar module computer programs without provision for automatic braking maneuvers. There has been some thought to reversing this direction. However, Don Cheatham, Aaron Cohen, and I agreed today to proceed as we are for the AS-207/208 programs–that is, do not provide automatic braking maneuvers…
AGC program status for AS-278
I guess enough things have happened affecting the status of the programs for the AS-278 mission that I ought to issue another status report. According to MIT, work is progressing along basically on schedule. The major effort is currently in Ed Copps’ area where coding of the program is going on which should be completed…
Spacecraft computer program requirements for AS-207/208, AS-503, and AS-504
On May 13 and 14, 1966, a flock of MSC people met with MIT people in Boston to discuss the spacecraft computer program requirements for missions AS-207/208, AS-503, and AS-504. This memorandum is probably one of several on the subject you will be getting in the near future. My main purpose is to describe the…
