EVERY ORBIT ON TIME

Express delivery from rideshare drop-off to operating orbit

Constellation roll-out as a service: we book the rideshare launch, integrate your satellites into our own transfer vehicle and release each one in its operating orbit. Rideshare cost, dedicated precision – flown on methalox propulsion we develop and build ourselves.

Taxi or train?

The difficult choice constellation operators face.

Two routes to orbit exist today – the taxi and the train – and neither delivers what a constellation actually needs.

Constellation satellites only earn revenue in their operating plane and altitude. A dedicated small launcher is the taxi: it delivers exactly that orbit, door to door, but at a price per kilogram that challenges constellation economics. A heavy-launcher rideshare is the train: cheap per seat, but it drops every payload at the same station – a standard orbit far from where the constellation needs it.

Today they pick one and pay for the other: in cash, or in months spent reaching the right orbit.

What operators actually wantRideshare cost + dedicated precision

Last-mile transfer

The best of both approaches.

MULE – our Multi-Orbit Logistics Vehicle – rides to the drop-off orbit as one payload among many, then flies the last mile on its own methalox propulsion. One contract covers the launch slot, integration and delivery: rideshare cost, flexible deployment, low time to market.

01Rideshare launch

A cheap ride to a standard drop-off orbit, shared with dozens of other payloads.

02Last-mile transfer

Our MULE OTV carries your satellites from the drop-off orbit to their operating plane and altitude.

03Operating orbit

Deployed in weeks instead of months, without paying for a dedicated launch.

Why it works · the propulsion behind MULE

Commercially viable in-space logistics is fundamentally a propulsion problem: kilometres per second of Δv, high thrust for rapid transfers, and both at a cost constellation operators can sustain. No such system existed, so we built it – the Cryogenic Propulsion Module.

Cryogenic performance with storable readiness

The Cryogenic Propulsion Module architecture.

The CPM integrates resonance ignition, multi-phase cooling, self-pressurizing tanks and passive zero boil-off into one flight unit. Each subsystem enables and improves the others – together they form an architecture that maximizes simplicity without compromising on performance. Every DeltaOrbit product is derived from this module.
