GROCERIES FROM THE SPACE PROGRAM?
What can the space program offer the grocery store? Plenty. Let
me relate the ways.
First, look at the benefits already showing up here on Planet
Earth from the space program: the most pervasive being the use of
communications satellites in the Clarke Belt (named after visionary
and science fiction writer Arthur C. Clarke who in 1945 "invented"
the theory). That "parking lot" over the equator, located at an
altitude of 22,300 miles, carry the geostationary satellites that
bring the world a great deal of the nightly news and carry a high
percentage of overseas telephone calls. Remote satellite sensing
(via Landsat 5 that orbits the earth every 14 hours and sees
everything every 14 days - at an altitude of 570 miles and always at
the same local daylight time)) is already used extensively in
assessing crop potential, disease, plant condition, soil types, water
content, insect infestations and plant stress. Other benefits are
appearing in ceramics, high heat-resistant moving auto parts, houses,
cutlery, robotics and sensing equipment. Now some of the early work
in "space farming" is starting to look promising. Take fish.
Fish, can't live out of water. Right? Wrong. It depends where
they live. The only reason fish die out of water is because their
lungs collapse from earth's gravity when they are removed from the
flotational qualities of water. You even "weigh" less in water.
In the weightlessness of space fish could live in mist. A 100percent humid, zero-gravity atmosphere, inside a space station could
provide more beneficial "new age" environment for space travellers.
We could have a new evolving aero-aquatic species, not of those who
swim beneath the seas but those who swim between the stars.
Dr. Thomas Heppenheimer, of the NASA scientific team, and
aerospace engineer was the first to come up with this idea and
suggests that farming in space may be a major benefit of the space
program. Dr. Heppenheimer and his colleagues believe that 10,000
people in space could be adequately fed on a mere 61 hectares (151
acres). The reason? Crop yields would be 10 times greater than on
earth. 24-hour-a-day sunlight, a continous year-round growing
"season", exact control of water, plant nutrition, temperature and
carbon dioxide designed for each type of growing organism. All this
without such harmful things as storms, hail, draught, frost, rodents,
weeds, pests and diseases in the earthly environment that reduce food
production. Such crops as corn could be 40 times more productive
than on earth.
Under the regid requirements of space, productivity means survival
(as it is becoming to mean on earth) hence goats would produce the
dairy products as they deliver twice as much milk as cows. Other
spin-offs may be from the field of genetic engineering. Experiments
considered too dangerous on earth could more safely be carried out in
the biological isolation of space.
Benefits from such research could be as revolutionary, as that on
European milk-maids, which caused Britain in 1853 to start compulsory
vaccination - starting us on the route to vaccine (named after
"vacca", the Spanish word for cow) therapy and pasteurization.
What may prove even more beneficial, is what we have learned from
researching for food in space: that there are more than 80,000 edible
plants in the world and we are currently, on a world-consumption
basis, eating less than four percent, just 3,000 of them. Alone, the
big Three: wheat, rice and corn are providing half our protein and
calories. Twenty-four other cereals supply another 45 percent. What
the potato and the tomato did for the diet habits of Europeans 300
years ago will be duplicated and demanded during the late Nineties
and the early years of the Third Millennium as we learn how to use
and distribute widely some of these other 77,000 edible plants.
Watch grocery shelves start to display an even wider variety of
wholesome foods for your dining table.
