1968.09.16 - Changes in the Apollo Program Specification

Apollo Program Director Samuel C. Phillips formally notified ASPO Manager George M. Low at MSC and Saturn V Program Manager Lee B. James at MSFC of changes in the Apollo Program Specification. As agreed on during the MSF Management Council meeting on August 6, the Apollo payload interface was set at 46,040 kilograms (with a flight geometry reserve of 137 kilometers per hour). Also, the present spacecraft loading philosophy allowed a total spacecraft weight of 46,266 kilograms for lunar missions having less than maximum flight geometry requirements.

Phillips repeated his earlier statement that he was prepared to relax some flight constraints to achieve the best possible balance on each space vehicle. (Although with recent changes in Saturn V loading, residuals, and J-2 engine thrust, apparently few if any of these constraints would have to be relaxed.)
