Spargo Space Information

Spargo Space builds refueling infrastructure for the orbital economy. Spacecraft today launch with a fixed propellant budget. When the tank runs dry, the mission ends — regardless of the value of the asset still on orbit. Spargo is ending the era of the single-tank spacecraft. Our system pairs two capabilities that only work as one: 1) The depot. A 2,000 kg storable-propellant depot (hydrazine/MON-3) using industry-standard interfaces, positioned where operators need margin, not where launch schedules put it. 2) The approach. A patent-pending advisory autonomy stack for rendezvous, proximity operations, and docking. A vision-language model provides advisory perception and guidance while a deterministic safety layer retains sole control authority — intelligence in the loop, safety in command.
