Who We Are: Space Kinetic is a dual use space technology startup building a completely new architecture for space operations - one that brings the advantages of proliferated drone technology (low-cost, operationally flexible, attainable, distributed) to space missions while reducing the ecosystem''s reliance on consumable fuel. Our goal is to move away from one-to-one space architectures - where each satellite in a constellation has one (or a small # of) primary payloads attached to the bus -- and unlock a 'one-to-many' system, where each satellite has a large number of payloads which can be deployed from their host spacecraft at high velocities without firing a thruster.
