Earth Search Sciences performed the test flight for an undisclosed client over a U.S. government outdoor field "laboratory" in the Nevada desert.

The work produced evidence of the existence of a mineral that Earth Search officials believe had not previously been identified by the use of remote sensing on the intensively studied field laboratory.

"There are indications that new mineral occurrences were identified for the first time, and on-site validation of those indications would be significant because this field laboratory is one of the most comprehensively studied areas in the world," said John Peel, chief executive officer of Earth Search Sciences. "The information the Probe 1 system gathered on this first commercial mission exceeded our expectations and those of our client."

Peel said Earth Search Sciences doesn't have access to the entire universe of information that has been gathered from the test area but several scientists familiar with the body of work there believe Probe 1's apparent detection of this mineral from an airborne platform is noteworthy.

The surveillance of the field laboratory occurred in late-afternoon light conditions only a few weeks after winter solstice, and Peel said the results open a new "window of opportunity" for remote sensing missions to be conducted globally because of the precision of the information gathered in those conditions.

The project marked Earth Search Science's first commercial application of its proprietary Probe 1 system. Remote sensing, or "hyperspectral imaging," creates ultra high-resolution images of the earth's surface. Analysis of these images can determine the presence of target minerals in geologic formations or evidence of minerals from vegetal "signatures."

Earth Search's Probe 1 instrument can be mounted aboard light aircraft for use in a variety of environments, including remote areas served only by backcountry airstrips.

"Probe 1 established its value in identifying potential mineral deposits during last summer's mission to Kazakstan, and we are pleased to put this breakthrough instrument to work for our clients," said Brian Savage, president of Earth Search Sciences. "This job employing Probe 1 is a significant step for Earth Search Sciences as we grow from a development company to full revenue production."

Earth Search Sciences in 1997 brought to market its Probe 1 hyperspectral imaging system following 10 years of research and development. The instrument was designed and manufactured under contract to Earth Search Sciences by Integrated Spectronics Pty. Ltd., of Sydney, Australia. Concurrently, Applied Signal and Image Technology, of Millersville, Maryland, developed near-real-time processing software for use in computers integrated with Probe 1.

Two more of the Probe 1 instruments are scheduled to be delivered to Earth Search Sciences in 1998.

Satellite Launch To Boost DTH In India
Calcutta, India (SPX) Dec 28, 2005
The successful launch Thursday of India's heaviest satellite from spaceport of Kourou in French Guyana may have boosted the country's space research efforts to yet another level, but it has also lifted the spirits of at least three Direct-To-Home televisions broadcasters, one of which has been waiting for years to launch its services in India.
