On April 20 we had our first meeting to establish spacecraft computer program requirements for the AAP missions. Sufficient time will soon have elapsed to permit substantial progress on the action items issued at that meeting making it worthwhile to gather again. Accordingly, you are invited to attend such a meeting at 9:00 a.m., May…

VHF ranging by CSM for ascent monitoring
Attention everyone!! As far as I can tell, everyone wants to get that VHF ranging device on the CM and there’s a big effort going on right now to put together the proposal and justification for it. Most attention to date has been given to its use for rendezvous. It is obvious that it should…

Mission C DAP initialization procedures
In a memo dated November 28, you recommend that “DAP initialization procedures for Mission G be established where either crew input requirements are eliminated entirely, or restricted at most to one inertia update following the largest SPS burn.” I am writing you this note to let you know that what has been planned is entirely…
First 2 hours on the moon is a countdown to launch – simulated or real thing.
Those who participated in the STAC presentation already know this, but perhaps some of you, like me, had not heard. It is currently proposed that on the lunar landing mission the first two hours on the lunar surface will be devoted to spacecraft systems checks and launch preparations which, for all practical purposes, simulates the…
Aborts from powered descent on the lunar landing mission
We spent the entire May 8 Ascent Data Priority meeting discussing mission techniques associated with aborts from powered descent on a lunar landing mission. This discussion led to some pretty simple procedures which are outlined in this memo. They are based on some assumptions which I’ve also listed below. If you feel that they are…
Lunar Rendezvous Mission Techniques
On May 28 we finally kicked off the Lunar Rendezvous Mission Techniques business. Because of the imminence of missions “D” and “E”, we started on those first some months ago. Now I wish we hadn’t because they are so darned complicated. I have a feeling the lunar rendezvous can be finished up quicker than they…
Lunar rendezvous shaping up
On June 26 we took another wack at the “G” Rendezvous Mission Techniques. I think we now have most of the basic things squared away so that we can get into the detail with some confidence. The most significant decisions were:…
