As I understand it, there has been a desire or requirement to have the capability of surviving a cryo-tank failure at any time in the lunar mission. After C’, it was decided to keep the IMU powered up throughout all lunar missions even though it might be at the cost of having the backup cryos….

How to land next to a Surveyor – a short novel for do-it-yourselfers
As you know a decision has been made for the H mission to land next to Surveyor III. Considerable amount of work has already been spent in figuring out how to perform a so-called point landing, but a number of computer program and procedure changes are required which cannot be implemented prior to this mission….
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…
Invitation to an Apollo 13 Lunar Orbit Mission Techniques meeting
“The time has come” the walrus said, “to talk of many things.” This classic quotation apparently now applies to the Apollo 13 lunar orbit mission techniques and this walrus is suggesting Tuesday, September 23. Bob Lindsay has subjected his flight plan to three iterations already and it’s shaping up nicely; the FOD guys have a…
We don’t have to change LUMINARY much for point landing but there’s gold in them hills!
On September 12 we had a spacecraft computer program requirements meeting for Apollo 13. We called it because there were a lot of proposals floating around which had been advertised as “needed for point landing.” On the other hand, these programs must be released for rope manufacture on about November 15 and so there obviously…
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….
Apollo Spacecraft Software Configuration Control Board meeting number 32
On October 9 Chris Kraft convened the first Software Configuration Board meeting since June 5 at MIT. We had a real pot full of PCR’s to discuss, some of which were approved for Apollo 13, some for 14, and some were put in a category in which MIT was to continue development to a point…
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…
Apollo 13 Mission Techniques are in good shape
On December 5 we had what I expect to be our last full-blown Mission Techniques meeting for Apollo 13. This memo is to tell you about it….
LM IMU drift checks prior to descent for Apollo 13 and up
We are making some fairly substantial changes to the way we are aligning and checking the drift of the LM IMU before descent on the Apollo 13 mission. Just for the record I would like to document what it is we are doing and why….
