Problem
Satellites in Very Low Earth Orbit (VLEO) require propellant to counteract atmospheric drag, limiting their lifespan and necessitating frequent refueling or deorbiting. Traditional chemical propulsion systems rely on finite fuel reserves, adding significant weight and cost to satellite missions.
Solution
Viridian Space is developing Air-Scooping Electric Thruster (ASET) technology that enables satellites to operate in VLEO by collecting atmospheric oxygen and using it as propellant. This innovative approach provides a virtually limitless fuel supply, extending satellite operational life and enhancing capabilities for various applications. By eliminating the need for large onboard propellant reserves, ASET technology reduces satellite weight and launch costs, while also enabling new mission profiles such as in-orbit servicing and active debris removal. The ASET system intakes atmospheric particles, compresses them, and then uses electrical energy to ionize and accelerate the propellant, generating thrust.
Target Audience
The primary target audience includes satellite manufacturers, operators of Earth observation and communication satellite constellations, and companies involved in in-orbit servicing, assembly, and manufacturing (ISAM).
