Space Science and Applications
Applying space sciences and associated technologies to detect and characterize national security threats
The Space Science and Applications Group (ISR-1) leads a variety of civilian and defense-related programs sponsored by the Department of Energy (DOE), the Department of Defense (DOD), the National Aeronautics and Space Administration (NASA), and other U.S. government agencies.

ISR-1 is composed of scientists and engineers with backgrounds in diverse areas such as Space Physics, Nuclear Physics, and Plasma Physics. They are engaged in pioneering science missions, developing sensors and systems to detect nuclear emissions and measure natural and man-made radiation. By providing satellite-borne gamma-ray, x-ray, and neutron detectors to the U.S. government, ISR-1 supports monitoring of the atmosphere and near-Earth space for nuclear detonations.
