Logisitics FOR THE
INDUSTRIAL SPACE AGE

Space transportation today is a series of bespoke, high-stakes launch “missions”. Argo is changing that.
‍
Our refuellable transportation spacecraft deliver to any orbit, on demand, moving the industry to responsive, low-cost intermodal logistics from LEO through cislunar space.
Explore Capabilities
Any Payload. Any Orbit.

Orbital Logistics

Satellite and other asset deployment, on-orbit sustainment and movement – bringing logistics to the space domain. Argo provides the lowest-cost delivery service to GEO and cislunar space by leveraging LEO launch, novel spacecraft design, high-performance water propulsion, and in-space reusability.
‍
Post-launch payload pickup decouples asset delivery from launch, enables reuse of our transport vehicles, and provides unprecedented flexibility, low cost, and reliability. Argo orbital logistics provides the foundation to build next-generation space architectures and enable sustainment functions in space.

Mission FLow

01
Launch

Your satellite or other asset launches to LEO on any launch vehicle, minimizing cost and maximizing schedule flexibility.

Launch integrated to Argo spacecraft, or independently.

02
ON-Orbit Pickup

Argo transport vehicle in LEO captures your asset after launch. Full launch vehicle fairing volume and mass capacity – small or large – can be used for payload.

Optional Capability
03
TRansit + Delivery

Dual-mode propulsion transports your asset to GEO, cislunar, or any destination orbit, efficiently and on schedule.

Mission Completed
04
Return + Refuel

Argo vehicle returns to LEO for refueling and reuse, driving down cost and enabling next-gen logistics.
