Armalite radar--used as proximity warning device for aircraft.

Miniature electronics and bearings--used for portable radio and
television; excessively small roller, needle and ball bearings used
for such equipment as air-turbine dental drills.

Epoxy missile resin--used for plastic tooling, metal bonding,
adhesive, and casting and laminating applications.

Silicones for motor insulation and subzero lubricants--used in new
glassmaking techniques for myriad products.

Ribbon glass for capacitors--used widely in electronics field.

Radar bulbs--used in air traffic control equipment.

Ribbon cable for missiles--used in the communications industry.

Automatic gun cameras--used in banks, toll booths, etc.

Fluxless aluminum soldering--used for kitchen utensil repair,
gutters, flashings, antennas, electrical joints, auto repairing,
farm machinery, etc.

Lightweight hydraulic pumps--used in automated machinery and
pneumatic control systems.

Voice interruption priority system--used for assembly line
production control.

Examples such as the foregoing, it might be pointed out, do not
generally emphasize an area in which space exploration is making
one of its greatest contributions. This is the creation of new
materials, metals, fabrics, alloys, and compounds that are finding
their way rapidly into the commercial market.

Less demonstrable but equally (and perhaps more) significant areas
which may expect to benefit from space exploration are set out
beginning on page 35.

which cause weather can be learned from meteorological satellites such
as these. Even a slight increase in the accuracy of weather prediction
will be worth millions of dollars annually.]

FOOD AND AGRICULTURE

An extremely difficult problem bound up with space travel of any
duration is that of food. Astronauts will not be able to take large
supplies of food on their voyages and probably will have to reuse what
they do take. Learning how to do this is no easy matter. Some doubt if
it can be done. Others are optimistic.

The body of scientists now working directly on space feeding and
nutrition is working effectively at a rate only attained by high
motivation. But this motivation suffices and their efforts will
ultimately provide
