FC/Acting Chief, Flight Control DivisionJUN 18 196868-PA-T-130APA/Chief, Apollo Data Priority CoordinationCan some pre-DOI activity be move to pre-LOI?
As you are no doubt aware, the crew timeline just prior to Descent Orbit Insertion (DOI) is terrible. This period of activity has grown almost to the point of being unacceptable. This is due to the extensive LM checkout – particularly that requiring telemetry coverage – which unfortunately conflicts with other activities such as making landing site observations.
Pete Conrad had a suggestion the other day which your people are probably in the best position to evaluate. It was his opinion that a lot of the LM checkout could be done prior to Lunar Orbit Insertion (LOI). One thing that makes this attractive is the continuous telemetry coverage we still have at that time. In any case, I would like to suggest that you have your people look into how much of the LM activation and checkout could be done at that time in order to relieve our serious pre-DOI situation.
