1968.02.08 - Decision to forego a second unmanned Apollo LM flight using LM-2


Grumman President L. J. Evans wrote ASPO Manager George M. Low stating his agreement with NASA's decision to forego a second unmanned LM flight using LM-2. (Grumman's new position - the company had earlier strongly urged such a second flight - was reached after discussions with Low and LM Manager G. H. Bolender at the end of January and after flight data was presented at the February 6 meeting of the OMSF Management Council.) Although the decision was not irreversible, being subject to further investigations by both contractor and customer, both sides now were geared for a manned flight on the next LM mission.

However, Evans cited several spacecraft functions not covered during the LM-1 flight that would have to be demonstrated before attempting a lunar mission, notably control by the primary navigation and guidance system of the descent propulsion system burn as well as control of stage separation and firing of the ascent propulsion system. To demonstrate these functions fully, he said, some modifications in mission plans for the next two manned flights might be necessary.
