The Space Science Division conducts a broad-spectrum RDT&E program in solar-terrestrial physics, astrophysics, upper/ middle atmospheric science, and astronomy. Instruments to be flown on satellites, sounding rockets and balloons, and ground-based facilities and mathematical models are conceived and developed. Researchers apply these and other capabilities to the study of the atmospheres of the Sun and Earth, including solar activity and its effects on the Earth’s ionosphere, upper atmosphere, and middle atmosphere; laboratory astrophysics; and the unique physics and properties of celestial sources. The science is important to orbital tracking, radio communications, and navigation that affect the operation of ships and aircraft, utilization of the near-space and space environment of the Earth, and the fundamental understanding of natural radiation and geophysical phenomena.

Geospace Science & Technology Branch (7630)


Objective: Conduct research to observe, understand, model, and forecast the geospace environment and its connections to its lower and upper boundaries, toward facilitating and advancing functional capabilities for the Navy/Marine Corps and other agencies.

High-Energy Space Environment Branch (7650)


Objective: Advance the understanding of the high-energy environment through the development and deployment of advanced detectors, simulation of the environments and operations concepts, and interpretation and theoretical modeling of the observed phenomena, thereby address priority S&T goals of DoD, NASA and other civilian agencies.

Solar and Heliospheric Physics Branch (7680)


Objective: Develop improved heliospace environment understanding, awareness, sensors, forecast capabilities, and monitoring tools that predict operational impacts and enable real-time threat warning; and transition these developments to support the Navy/Marine Corps and other agencies.
