Cyber Defense Subsidiary Techsphere Signs Space Act Agreement with NASA.

ST. PETERSBURG, Fla. -- Cyber Defense Systems, Inc. (OTCBB: CYDF), a designer and developer of next generation unmanned aerial vehicles (UAV's), and its wholly owned subsidiary Techsphere Systems International, Inc. (TSI), a designer, developer and manufacturer of manned and unmanned airships, announced today the signing of a Space Act Agreement between Techsphere Systems International (http://www.techsphere.us) and The National Aeronautics and Space Administration (NASA) Langley Research Center (www.nasa.gov/centers/langley/about/index.html).

This agreement partners NASA, TechSphere Systems, Unitech, LLC (www.unitechcorporation.com), Applied EM, Inc. (www.appliedem.com) and RTI International (www.rti.org) to conduct a study for the purpose of developing a microwave sensor conceptual modeling tool to enhance the existing Langley Research Center vehicle analysis tools to enable the sensor/vehicle to be jointly developed from the science requirements. This Innovative Partnership Project will provide an assessment of ongoing airship technology development and support the validation of existing Langley Research Center modeling. Lightweight conformal "paint-on" antenna concepts will also be studied to predict its overall performance.

"This is a wonderful opportunity for us to contribute to an exciting and innovative partnership supported by NASA," said Mike Lawson, President of Techsphere Systems International.

"This Space Act Agreement, sponsored by NASA's Innovative Partnership Program, will help achieve NASA's goals of utilizing High Altitude platforms for gathering of hard science for the betterment of our Earth," stated Wes Lawrence, Deputy Chief of the Electromagnetics and Sensors Branch of NASA Langley Research Center.

After the commencement of this agreement, periodic reports will be completed summarizing Techsphere Systems (TSI) airship flight operations and computer modeled test results for Cyber's M.A.R.S. airship design. The flights conducted and planned in the near future will provide aerodynamics information from the results of Aerosphere airship flight tests. This information will be used with Langley Research Center System Analysis models and the assessment of the Airship technology as a stepping process to achieve an overall high altitude capability in the 60,000 to 70,000 foot altitude regime. This will allow predicted station keeping capability for NASA remote sensing applications.

"We are very pleased to be partnered with NASA and thrilled to offer our products and expertise to further develop an already outstanding model established by NASA's Langley Research Center," commented Mr. Billy Robinson, CEO of Cyber Defense Systems Inc.
