Spargo Space Information

Spargo Space is building the infrastructure backbone for in-space refueling. We develop AI-enabled, refuellable orbital propellant depots and the autonomous docking systems required to service them. Our focus is infrastructure-scale logistics: repeatable, high-throughput propellant storage and transfer that enables sustained spacecraft operations without reliance on single-use propulsion margins. Space missions are fundamentally constrained by onboard propellant. This drives conservative mission design, shortened lifetimes, and inefficient architectures. Most refueling efforts focus on small demonstrations or one-off servicing. We are building scalable logistics infrastructure. Spargo Space is developing 2000 kg orbital fuel depots capable of storing and transferring hydrazine and cryogenic propellants at operational scale. These depots are paired with closed-loop autonomous rendezvous, proximity operations, docking, and propellant transfer systems designed for repeatability, fault tolerance, and minimal ground intervention. Our core technologies include long-duration propellant storage, hydrazine and cryogenic-compatible docking and transfer interfaces with thermal isolation and robust sealing, AI-augmented GNC for autonomous RPOD under degraded sensing, and modular architectures supporting multiple vehicle classes and mission profiles. Near-term applications include life extension for spacecraft in LEO and cislunar space, logistics support for stations and orbital platforms, refueling nodes for tugs and servicers, and enabling higher-energy missions without dedicated launch stages. We treat autonomy as a core operational requirement. Our systems are engineered for repeated docking cycles, standardized interfaces, and scalable propellant throughput. Our mission is to make propellant a service, not a constraint, and enable persistent operations in Earth orbit and beyond.
