3. Explanation of DISCOVERY: The major stated purpose of the
DISCOVERY series will be the development of hardware ultimately useable
for either military or peaceful scientific purposes. Specifically it will be
said to involve the study of stabilization, orbit ejection, recovery techniques,
vehicle separation as related to re-entry, and engine-fuel reliability. All
of these investigations are necessary for the development of space vehicles
and to advance the state of the art in pilotless space operation. Included
in the explanation will be the statement that several of the DISCOVERY
series are to carry biomedical payloads to test environmental conditions
of the upper atmosphere. These flights will be reported as contributing to
the joint NASA/ARPA Man-In-Space program.
4. Additional Explanations:
a. Patrick Air Force Base is crowded and new facilities will
be available at the Pacific Missile Range so launchings will be
conducted from the latter location, Range safety considerations
make it impossible to launch in an easterly direction and take
advantage of the speed of the earth's rotation. To launch in a
westerly direction would be to accept too large a speed penalty.
Accordingly, it is necessary to accept the 165° - 180° direction
of launch which implies a polar orbit.
b. The use of polar orbits will have the further advantage of
permitting an exercise in the near future of the early warning net
established to guard against enemy attack.
c. Later launchings will contain equipment to study solar
power, infra-red early warning and terminal guidance control,
and to conduct model testing of maneuverable space vehicles.
