SMALL SPACECRAFT TECHNOLOGY INITIATIVE
CTA Spacecraft
Industry and universities will use data coming from both Smallsats to assess market potential and development for a number of possible commercial applications. CTA's Smallsat combines a very high resolution optical element with stereo imaging and cloud editing capabilities, and includes separate instruments to map global sources and distribution of pollutants in the atmosphere.
1. Potential applications in Urban Planning include:
*Detect and determine growth patterns, population, and city expansion;
*Determine optimum urban siting for public facilities such as airports, convention centers, power plants, and the like;
*Assess and project future requirements for regional urban transportation infrastructures including roads, rail and waterway systems, mass transit, and large and small airfields;
*Assist utilities in assessing the status of existing systems and possible future sites for electrical, cable TV, telephone lines, water and sewer, and energy pipelines.
2. Potential applications in disaster management include:
*Assess damage following disasters and to plan mitigation efforts in the wake of disasters such as floods, tornadoes, hurricanes, earthquakes, and others.
3. Potential applications in other commercial areas include:
*Assess land use and existing infrastructure for developers and construction companies;
*Provide risk assessment information for the insurance industry;
*Provide potential land sitings for businesses based on urban growth patterns and transportation data ranging from fast food franchises to shopping malls located anywhere throughout the globe;
*Provide individual tree counting for the timber industry.
4. Science applications include:
*Demonstrate viability of getting X-ray emission data from the sun using low mass, moderately-cooled instruments for possible future Discovery missions;
*Provide continuous global coverge of pollutant sources and their distribution in the atmosphere.

SMALL SPACECRAFT TECHNOLOGY INITIATIVE
TRW Spacecraft
The TRW spacecraft data will be used to assess and qualify commercial opportunities and value-added information for industries and local, state and regional government organizations.
1. Potential applications in agriculture include:
*Assist in crop stress management due to heat, drought and storm damage;
*Determine crop maturity and the optimum time for harvesting-especially for high-water value crops such as peas, melons, tomatoes and other fruits and vegetables;
*Provide the farmer with pinpoint pesticide and fertilizer requirements down to the square yard-with potential to lower farmer costs by 75 percent;
2. Potential applications in forestry and land management include:
*Determine the health and variety of forest species;
*Determine tree diseases and insect infestations which may be affecting stands;
*Determine the effects of harvesting;
*Assist forest managers by providing verification of ground-truth databases;
*Provide tracking information on seasonal watershed changes;
3. Potential applications in environmental assessment and compliance include:
*Providing data which can be used to enforce compliance with existing environmental regulations;
*Monitor rivers and other watershed areas for evidence of pollution or illegal runoff;
*Monitor the progress of EPA Superfund cleanup sites;
*Monitor urban and rural areas for evidence of illegal or toxic waste dumping;
*Provide the EPA and other local and regional organizations and companies with an assessment of how well cleanup and compliance activities are working;
*Assist analysis and assessment of global warming concerns by providing information about leaf and forest canopy chemistry;
*Measure the effect of oil spills, pollution in the oceans, pipeline integrity, water contamination, coastal dumping, wetland degradation, and other water ecosystems.
4. Potential applications in other industrial areas include:
*Monitor the ocean color to help fisheries find prime fish harvesting areas;
*Explore for minerals and precious metals based on geological assessment from space;
*Help state, federal, and international law enforcement officials by providing information about illegal drug crops growing in remote locations.
5. Science applications include:
*Measure astrophysical components of extreme ultraviolet cosmic background with improved resolution compared with prior instruments;
*Provides high spectral and spatial data to complement planned EOS instruments and directly supports science applications for plant and ocean biology, geology and polar climatology
