During a discussion on the Saturn program, several major problems were brought up:
- The adequacy of the Saturn C-1 launch vehicle for orbital qualification of the complete Apollo spacecraft was in question. Although the C-1 could be used to launch a command module of 5,100 pounds, it was probable that the command module weight would increase to as much as 8,000 pounds, George M. Low of NASA Headquarters, in a critical review of the Apollo program, pointed out that a spacecraft for a circumlunar mission could be constructed within the payload limitation of the C-2 launch vehicle. Both the developmental and production spacecraft could be available to meet the Saturn schedules.
- Much basic research would be needed before the first Apollo flight, In particular, the problem of reentry heating was of great concern. Low noted that a prediction criterion for proton beam events had been developed, making possible safe manned circumlunar flights insofar as the radiation problem was concerned.
- Concern was also expressed as to the possible need and availability of additional personnel to support the Apollo program.
