Mr. C. C. Kraft announced at his Monday morning meeting that the EMS will be used for controlling reentry on the “C” mission in the event of a G&N failure regardless of when that failure occurs. This was decided over his mild objection at George Low’s CCB meeting last week….

Sextant Rendezvous Navigation Review
As noted in the attached memorandum, I would like to request your active participation in a meeting on April 25 to review for “C” mission operational personnel the work your people have done on CSM sextant rendezvous navigation. I think, in order in insure proper use of the CSM G&N during the spacecraft 101 flight,…
Proceed button
Looks like we’re approaching the final chapter in the proceed button story. As I understand it, all manned Apollo spacecraft will have computers wired such that the standby button serves the dual purpose of standby function, as before, and a proceed function duplicating Verb 33 Enter. At least, that is the current intention. Apparently there…
Apollo 205/101 reentry procedures
ASPO’s Systems Engineering Division wrote a memo outlining general procedures to be used by the Spacecraft 101 crew following a G&N controlled deorbit burn and also specifying that an automatic reentry would definitely not be performed. You forwarded that memo to me questioning whether our Data Priority Coordination group had looked into this subject and,…
Third Trajectory Control Data Priority Meeting for Spacecraft 101
At 9:00 a.m. on December 20, 1967, in Room 966, Building 2, there will be a Trajectory Control Data Priority meeting to review the detailed logical flow charts prepared at MSC defining the retrofire and reentry phase of the S/C 101 mission. Appropriate comments shall be incorporated and they will be reissued as configuration controlled…
“C” Mission Retrofire and Reentry Mission Techniques meeting
On Friday morning, July 19, we had a “C” Mission Retrofire and Reentry Mission Techniques meeting to clean up some open items. It is evident that a distribution of correction pages to our previously distributed Mission Techniques document will be inadequate and it is our current plan to republish the whole book. Some of the…
“C” Rendezvous W-Matrix
This memorandum is to inform everyone in writing that MIT has now agreed with MPAD that it is acceptable to use the same values of the W-Matrix when reinitializing (after three marks of the last batch of marks between NSR and PTI) as are used initially. That is, it is not necessary for the crew…
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…
Good news on “C” mission SPS burns
The following is a verbatim copy of a note to me from Rick Nobles…
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…
