On February 1 a bunch of us who had been working on operational procedures associated with lunar landmark tracking got together with some of the Lunar Mapping people who have the responsibility for selecting and precisely locating the lunar landmarks to be used. This was a rather refreshing get together since, as strange as it…
Fourth Mission “C” Rendezvous Mission Techniques meeting
As a result of our deliberations today (February 16) I think we have finally determined what to do about delta V residuals on the NCC₁ maneuver. Previously, it had been stated that we would probably trim out small values but, in order to save RCS, would allow larger values to propagate to the subsequent maneuvers,…
We will start Data Priority Mission Techniques meetings on the Mission “E” Rendezvous.
Just as the deadline proclaims—we will have our first “E” Rendezvous meeting at 10:00 a.m. on Monday, March 4, 1968, in Room 390, Building 4. It will be a short kickoff affair with emphasis on getting up to date on the mission and flight plans as they exist today….
Apollo 13 Odds and Ends Meeting
This memo is to notify you of an Odds and Ends Mission Techniques meeting for Apollo 13 on December 5, 1969, starting at 9 a.m., Room 378 of Building 4. Very likely it will be the last big get together we will have for that mission. Generally, subjects to be discussed result from the effect…
“C” rendezvous open item clean up
Paul Kramer, Phil Shaffer, Duane Mosel, Ed Lineberry, and myself spent the morning of May 7 trying to close our major open items remaining on the “C” mission rendezvous. These items were:…
Rendezvous radar will be available during critical mission phases.
Something rather astounding happened at the Apollo Spacecraft Software Configuration Control Board meeting on Tuesday, January 30. It was so shocking the word spread like wildfire! But just in case you have not already heard, it looks like we are going to get rendezvous radar data on the downlink during the critical LM powered flight…
Two-stage LOI looks good after C’
Just like in other fields of endeavor, it always seems possible to use actual flight results to prove how smart you were before the flight. I am writing this note to crow about how C’ proved we “done right” in planning a two-stage LOI….
Third Mission “C” Rendezvous Mission Techniques meeting
Based on our two previous meetings, TRW had prepared the first version of the mission techniques flow diagrams for the “C” Mission Rendezvous. This meeting on February 2 was devoted to going through that flow. As usual, in spite of the fact we thought we had everything all worked out, we ran into numerous items…
Apollo 12 Newsletter
So many things have changed – some subtly, some considerably – that I thought a newsletter might be useful. It is written particularly for those of you who have not been directly involved in preparation for Apollo 12….
Lunar Reentry Mission Techniques meeting
On February 1 we had another meeting on lunar reentry mission techniques. Almost all of our discussion dealt with the final midcourse maneuver prior to entry. As you know, midcourse maneuvers are currently planned to occur approximately 12 hours after TEI which is near the sphere of influence of the moon and about 15 hours…
