Since we have gotten the uplink capability in the LM, some things have been done to make it possible to load the erasable memory in the spacecraft computer while in flight, but possibly not enough….
PIPA Surprise
Since I was surprised at what Gunter Sabionski told me and, in turn, almost everyone I have told has been surprised, perhaps you too will be surprised to learn that the least significant increment output by the CSM accelerometer is equivalent to 0.2 fps! (The LM is considerably better, the value being 0.03 fps per…
A lengthy status report on lunar point landing including some remarks about CSM DOI
It is clear that lunar point landing capability is absolutely necessary if we are to support the exploration program the scientists want. That is, mission success intrinsically depends upon it. (The current definition of “point landing” is for the LM to touchdown on the lunar surface within 1 kilometer of a point referenced to specific…
Guidance system oriented ground rules for TLI Go/No Go
This memo is to document the guidance system oriented ground rules we intend to apply in the development of mission techniques for making the Translunar Injection (TLI) Go/No Go decision, unless directed otherwise. Effective immediately, it is intended that all RTCC computer programs, MCC displays and decision limit lines, crew and ground procedures and timelines,…
Results of “C” Mission Rendezvous Review meeting – April 22, 1968
At your request, I set up a meeting on our current “C” mission rendezvous problems with participation by all organizations interested in this activity. The attached attendee list will show you they were well represented. Our basic purpose was to determine current status of the situation and to recommend where to go from here with…
F Rendezvous Mission Techniques Clean-up
On April 5 we had what I expect is the last of the F Mission Rendezvous Techniques meetings. We resolved a number of open items which had not been covered before, or which popped up during simulations. This memo is to list them for the record. Some are trivial, some are really quite significant….
Status report on Apollo 13 Mission Techniques – or “Go for CSM DOI”
Based on the September 23 Mission Techniques meeting, it appears that the command module DOI type mission should be adopted for Apollo 13. At this meeting we reviewed all facets of this approach and could find none that would keep us from going this way; on the other hand, the advantages appeared to be substantial….
Fifth “C” Mission Rendezvous Mission Techniques meeting
We had another “C” Mission Rendezvous Mission Techniques meeting on February 23. We resolved a few things and reworked the flow charts some more at this meeting….
Apollo rendezvous guidance computer program options
The purpose of this memorandum is to inform you of two special features of the Apollo spacecraft rendezvous guidance computer programs you may not be aware of since we just added them to the system….
ALEXANDER’S Rent-A-Car, Inc.
This is an unsolicited evaluation of ALEXANDER’s rental car service at Boston. The service these people have provided has been so much better than that which we previously had that I’m prompted to write this note. The people are consistently friendly, helpful, and prompt about pick up and delivering to the terminals. And the cars…
