Dr. Killien next introduced Dr. York, who, he indicated,
would discuss various illustrative space science programs designet.
to achieve the objectives of space science. which had just been outlined,by Dr. Purcell.
Dr. York spoke first, using a chart, of the vehicles which
would be used in the exploration of outer space. The first usabie
vehicles would be the IRBMs--JUPITER and THOR--with added stages.
Such vehicles would be available late in 1958 or early in 1959.
They would eventually be able to carry a pay-load (instrumentation,
etc.) weighing 500 pounds.
Later on in the process, Dr. York indicated that ICHM vehicles would become available for space exploration. Either TITAN
or ATLAS could be used, perhaps in 1961, with a third stage added
to them. The pay-load carried by these vehicles would be much
larger than that which the IREMs could carry. The pay-load for an
earth satellite could be as large as 6500 pounds if fluorine were
used for fueling, or 3800 pounds if the ICBM were fueled with liquid
oxygen (lox). For a moon-hit or a Mars-hit, a pay-load of 2150
pounds with fluorine and 1000 pounds with lox could be carried.
Dr. York cautioned that even an ICEM venee= notcute
ficiently powerful to get a man to the moon. To do
we wo
have to construct a very large new rocket with a weight of 1.5 million pounds gross. He estimated the cost of developing such a new
rocket as lying somewhere between $500 million and $1 billion.
After describing the various sample or illustrative space
science and exploration programs, Dr. York turned to the subject of
the approximate costs of such programs. The cost of any effective
space exploration program would begin at $275 million a year, and
would be likely to reach a cost of $650 million a year by 1965.
Such figures, moreover, said Dr. York, were minimal.
Dr. York pointed out that a probing of the planet Mars,
which might be achieved by the UnitedStates in 1962, would probably be the first achievement we could count on doing before the
Russians, because they were so far ahead of us in big boosters.

In bringing the report to a close, Dr. Killian, followed
by Secretary Quarles, stressed the security aspects of the informstion which had been provided for the Council, most particularily with
respect to the final portion of Dr. York's presentation. Dr. Killian
