Exploring the Unknown 577
3. Operational capability in space.
It is our considered opinion that the LOR mode, which requires the
development of both the C-5 launch vehicle and the rendezvous technique,
provides as comprehensive a base of knowledge and experience for application to
other possible space programs, either military or civilian, as either the EOR mode
or the C-5 direct mode. The decision to delay Nova vehicle is dictated as much
by economic considerations, both fiscal and manpower, as by the technical need.
The realities of our budget do not allow for the almost simultaneous development
of two major launch vehicles. In addition, the redefinition of the Nova for payload
capability considerably in excess of the C-5 will, I am convinced, provide us with a
better national capability in the long run.
The question of evaluating the effects of environmental stress in the
various mission modes is a difficult one. This area is one in which there has been
considerable debate, and we are attempting to place the comparative data on
a more sound scientific basis. I doubt, however, that this can be accomplished
in time to contribute significantly to our present deliberations. Again, it is the
considered opinion of our people that there are no significant differences between
the modes in the area of stress on the astronauts.
[3] I appreciate the interest you and your panels continue to show in our
program. I have passed your comments and the Report of the Space Vehicle Panel
of July 26, 1962, on to Mr. Holmes and Dr. Shea for their consideration. This
constructive criticism by eminently qualified men is of tremendous value, and I
am looking forward to further discussions with you as the results of our present
studies begin to crystallize.
Sincerely,
