Kreios Space Tests Air-Breathing Satellite Propulsion System
TL;DR. Kreios Space plans an in-orbit test for its air-breathing electric propulsion system, designed to maintain satellites in very low Earth orbit. - The system collects atmospheric gases as propellant, eliminating the need for onboard fuel tanks for VLEO operations. - This technology could enable satellites to fly closer to Earth, delivering higher-resolution images and stronger signals. - The first mission, using a Kongsberg NanoAvionics microsatellite, is scheduled for 2028.
- Kreios Space developed an air-breathing electric propulsion system for satellites.
- The system uses atmospheric gases as propellant to counter drag in very low Earth orbit (VLEO).
- It aims to allow satellites to operate longer and more efficiently at altitudes between 100 to 400 kilometers.
- The first in-orbit test mission is planned for 2028 using a microsatellite.
