In other news, DRS will produce short and very long wavelength IR focal plane array sensor modules to support the Wide-Field Infrared Survey Experiment satellite in the NASA Medium Explorer program. The project will result in a stellar infrared map that is more than a thousand times more detailed than previous surveys. DRS received the $5.4 million contract from the Space Dynamics Laboratory of the Utah State University Research Foundation in North Logan. Its Sensors and Targeting Systems unit in Cypress, Calif., will fabricate the devices.
