A STTR Phase I contract was awarded to Physical Sciences in August, 2022 for $249,994.0 USD from the U.S. Department of Defense and United States Air Force.
Physical Sciences Inc. (PSI) is partnering with Brookhaven National Lab (BNL) and Tethers Unlimited Inc. (TUI) to combine PSI’s patent-pending passive cathode coatings and devices developed for spacecraft electrostatic discharge mitigation with TUI’s flight-proven, TRL9, tether-based deorbit system. The synergy of these technologies will rapidly result in a passive high altitude electrodynamic tether deorbit system capable of deorbiting satellites in
