Infrastructure for a Multi-Orbit Economy

Our refuellable orbital transportation vehicles deliver to any orbit, on demand, moving the industry to a responsive, affordable multi-modal logistics system.

Logistics 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.

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.

Use your propellant for your mission, not to orbit raise

Smallsat delivery to any orbit, on your schedule

On-orbit assembly; logistics for next-gen space assets

Defense

Large asset (10,000kg) delivery to GEO at dramatically reduced cost

Unprecedented space vehicle deltaV

Space movement and maneuver, decoupled from launch

Pre-positioning, reconstitution, repositioning, and resupply

Civil

Affordable, on-demand cislunar and interplanetary smallsat delivery

Novel mission architectures enabled by decoupled transport

Maximize science payload – Argo provides the deltaV

ESPA-class spacecraft to GEO and Lunar orbits

How it Works

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.
