On February 13 we went over our Descent Abort Mission Techniques with the world. In general they were accepted as is. That isn’t to say we didn’t have some lengthy discussions resulting in some improvements and/or changes but we didn’t make any substantial changes to the basic ground rules, philosophy, or overall procedures. I would…

Seventh “D” Mission Rendezvous Mission Techniques meeting
At the seventh “D” Mission Rendezvous Mission Techniques meeting on March 25, we spent most of our time discussing activity in the football rendezvous, specifically, under what circumstances and how to abort. It turned out that the same ground rules and techniques probably apply equally well to the pseudo-TPI maneuver halfway through the rendezvous exercise….
Descent Orbit Insertion (DOI) monitoring and abort procedures are proposed
Something rather interesting came out of Floyd Bennett’s April ?? Descent Mission Techniques meeting that I would like to pass around. It has to do with monitoring the DOI maneuver….
Is display of max g in P-61 any good?
During our lunar landing GSOP review someone commented that the display of max g in P-61 is of no use at all. It was said to be grossly in error for earth orbit reentry and of no value in determining appropriate action during entry from lunar return or following an abort when it is more…
AGS/PNGCS incompatability review – Chapter One
At the January 8 meeting of your CCB I was given the action item of reviewing AGS SCP’s Nos. 34 and 35. Specifically, I was to determine our position on the advisability of making these changes which you tentatively approved at that meeting, and, in particular, we are to satisfy ourselves that the AGS and…
Manual Steering for LM Ascent
Over the years various groups have attacked the problem of if and how the crew can manually steer the LM back into orbit from the lunar surface. These studies were started before GAEC was even selected to build the LM and some analysis is still going on to define the optimum pitch attitude profile, which…
D Rendezvous Mission Techniques
The final review of the D Rendezvous Mission Techniques will be held on Wednesday, January 15, starting at 9:00 a.m., in Room 383, Building 4….
Descent monitoring at MCC
We have reached a plateau in our work on Descent Monitoring, perhaps making it worthwhile to send out this memo. First of all, I don’t think there is any question that Descent is the thing that requires most of our attention between now and the G mission, at least in the empire of Mission Techniques….
“Any time” LM lift off is an unnecessary constraint
No big deal, but I’d just like to point out that I don’t agree with something in the memorandum to TA/Director of Science and Applications, dated March 19, 1968, subject: Operational constraints for the fourth lunar landing mission, which you signed. It stated in part, “It is the opinion of the Flight Operations Directorate that…
Crew monitoring of the LOI maneuver
On August 3 we had an informal meeting to talk about crew monitoring of the Lunar Orbit Insertion (LOI) maneuver. The subject came up in connection with Jim McDivitt’s preparation for the STAC presentation. I’m writing this note because we tentatively agreed on some fairly basic points with regard to how we might use the…
