Engineers with the Air Force Research Lab’s materials and manufacturing directorate at Wright-Patterson AFB, Ohio, say they have successfully integrated two existing technologies to create a new thermal control system for future satellites. The new active-temperature control system is compact and much lighter than state-or-the-art devices with similar functions, requires very little power, and has minimal data storage requirements. It combines an electrostatic radiator, developed by Sensortek, Inc., of Costa Mesa, Calif., and a heat-flux-based emissivity measuring method created by Advanced Thermal and Environmental Concepts, Inc., of College Park, Md. After testing in a large vacuum chamber, the system was included as part of NASA’s MISSE-6 on-orbit experiment that was carried into space in March by the Space Shuttle Endeavor.

Air Force Changes Rules for Pregnant Aircrew—Again
April 3, 2025
The Air Force is changing its policy for pregnant aircrew, generally reverting to rules set in 2019 that barred female aviators from flying during the first trimester—or from flying in aircraft with ejection seats at all—due to potential risks to the pilot and her unborn fetus.
