FM/6 Chief, Rendezvous Analysis BranchAUG 28 196767-FM-T-70FM/Deputy ChiefDoes the landing radar mess up?
This memorandum is to request that you look further into the business of how the use of landing radar observations in the spacecraft computer during descent influences the onboard determination of the final landing point. Hopefully, the landing point is essentially fixed prior to processing of the landing radar data but that may not be the case. It might really foul it up quite a bit. Our problem, of course, is to select the best LM position for use in subsequent real time rendezvous mission planning, that is, lift-off time and plane change required.
