Relative orientation of the LM and CSM navigation bases
Unless some unexpected problem arises, it is currently planned to align the LM platform on the “D” mission for the docked DPS burns without AOT star observations.

D Rendezvous Mission Techniques
This memo is to let you know about some things on the D Rendezvous that have been giving us a lot of trouble. The problem we have been having is associated with the football trajectory and how to exit from it gracefully. It seems like most of the significant mission techniques open items deal with…
Some Mission D contingency plans
During a recent D mission rules review a couple of interesting things came up that I hadn’t heard of before. You probably ought to know about:…
Should LM RCS jet #10 be disabled for the “D” mission docked DPS burn?
The following paragraph is extracted from MIT’s Spacecraft Autopilot Development Memo #11-68, dated July 24, 1968, by William S. Widnall….
