Christopher C. Kraft has a Joint Program Development Plan meeting at MIT on February 12. I would just like to pass on to you a couple of things that were interesting to me….

AAP Rendezvous Mission Techniques
In order to help solidify requirements for the AAP CSM computer program we are having a Mission Techniques type meeting on Tuesday, January 27 at 9 a.m., in Room 378 of Building 4. The specific subject to be discussed is the rendezvous phase of the AAP mission. The thing we are particularly anxious to pin…
G Rendezvous Navigation OJT is proposed
CMP Mike Collins called the other day to ask if there is any reason why he should not do active rendezvous navigation between DOI and PDI on the G mission. That is, he would like to run P20 incorporating sextant and VHF ranging data to update the LM state vector in the CMC. His primary…
How do we get and use LM rendezvous radar observations?
There is a lot of concern at the present time regarding the manner in which the LM rendezvous radar data is to be processed onboard the spacecraft. I feel that you should devote as much attention to this as you possibly can since it influences both the formulation of the spacecraft computer program and, to…
Rendezvous maneuver targeting for guidance system backup
During the “D/E” Rendezvous Mission Techniques meeting of April 15, we spent a lot of time discussing the data transmitted from the ground to the spacecraft involving the CSI and CDH maneuvers. This discussion, of course, centered on how the data should be used and led to a tentative conclusion regarding the backup of these…
Descent Aborts and subsequent Rendezvous Mission Techniques
On April 28, 1969 we reviewed the Descent Aborts and subsequent Rendezvous Mission Techniques with the crew and the rest of the world. I think most of this is quite complete and agreeable to everyone concerned, with one major exception. I was shocked and ashamed to find that I had badly misunderstood the situation regarding…
Apollo Mission Techniques Documentation Schedule
Here is another Mission Techniques Documentation Schedule, since the last one is three months old and barely reflects real life any more. The Lunar Orbit Activities Document will almost certainly have to be updated to reflect whatever we learn on the F mission. A June 30 release date for that update will be kinda late,…
Analysis of LM rendezvous navigation is needed
This memorandum is just a reminder for a couple of action items I discussed with you coming from the lunar landing GSOP review August 17. I think it is very important that you really get on with analyzing the performance of the rendezvous navigation in the LM using the radar. Two items you should specifically…
Tweak burns
If you can stand it I would like for you to hear the latest on tweak burns – the trim maneuvers made after LM insertion from a descent abort. I thought we had this settled and on ice a couple of months ago but some things have happened which probably make it logical to revise…
F Rendezvous Mission Techniques
We had our first F Rendezvous Mission Techniques meeting on November 12. We went through the whole thing rather smoothly with very few open items, probably due to all the past work on D and G. Obviously it is a much simpler exercise than the D rendezvous. This memo is to record a few of…
