NASA and EPA Team to Improve Crop Management
http://www.spaceref.com/news/viewpr.html?pid=16805

Can you see the difference between traditional corn and bio-engineered corn?
NASA technology is beginning to provide the answer in a snapshot.

The technology is called hyperspectral imaging. It uses a special camera to
cut one snapshot into 120 color-specific images. Hyperspectral means getting
many more images within the spectrum of just one picture. Each image shows a
unique characteristic not visible to the human eye.

The hyperspectral camera and its applications were developed by the Institute
for Technology Development at NASA's Stennis Space Center, Miss. The
Institute is one of several NASA Research Partnership Centers managed by the agency's
Marshall Space Flight Center, Huntsville, Ala.

The Environmental Protection Agency (EPA) teamed with NASA to use the
technology to ensure appropriate management practices are used to avoid the
development of resistance in corn pest populations. Pest resistance could severely
limit the continued use of these new varieties of corn. With more than 25 million
acres of corn planted this year, it is physically and economically infeasible
to sample each one. This new technology seeks to provide an active monitoring
capability to inform the grower of pest resistance development. Early use of
hyperspectral imaging provides the ability to distinguish between the two types
of corn and identify pest infestation conditions. Bio-engineered corn has
inserted genes to make the plant resistant to insects.

The EPA is using a small hyperspectral camera mounted on an aircraft. The
aircraft flies at approximately 8,000 feet, imaging the same sites every 10 days
during growing season. The images are put into a computer system, and
data-mining techniques are used to extract information about the corn.

"This effort will enhance NASA's understanding of image processing techniques
to extract knowledge from hyperspectral data sets," said Brian Mitchell of
NASA's Space Partnership Development Program at Marshall. "The research being
conducted with genetically modified plants and plant growth has the potential to
contribute significantly in our ability to grow sustainable and nutritional
crops in space. This could prove vital for long duration exploration missions."

The hyperspectral technology supports the Vision for Space Exploration and
long-term spaceflight goals. The Vision calls for returning the Space Shuttle to
safe flight, completing the International Space Station, human and robotic
exploration of the Solar System.

"This knowledge is vital to future Mars missions," said George May, director
of the Institute for Technology Development. "When we go to Mars, we will have
to grow our own food. This technology enables early detection of stresses in
plants, such as nutrient problems, so corrective action can be taken to
maintain the food supply."

Hyperspectral imaging may be used to treat crew injuries in space. The
Institute is working on a portable, handheld camera to take images of a wound site.
Using that image to identify wound severity and healing progress will allow
doctors to decide the best treatment. The imaging could save precious diagnostic
time, which would also improve healing by ensuring timely and proper
treatment.

Hyperspectral imaging will also detect mold and toxins in spacecraft, a
needed tool during long-duration missions to ensure crews have a clean, healthy
environment.

The patented, portable hyperspectral sensor was inducted into the Space
Foundation's Space Technology Hall of Fame in April. The Space Foundation is one of
the world's premier non-profit organizations supporting space activities,
space professionals and education. The Hall of Fame honors innovative technology,
originally developed for space use, converted for use in commercial products.
