Phase Four Secures DARPA Contract for Air-Breathing Electric Propulsion System
The Defense Advanced Research Projects Agency has awarded Phase Four a $14.9 million contract to develop an air-breathing electric propulsion system for satellites in very low Earth orbit. The contract is part of DARPA’s Otter program, which seeks to integrate air-breathing electric propulsion that uses ambient low-density air as propellant, providing satellites with an onboard […]
