The mission

Getting to space is the first problem.
Working there is the next.

Today
01

Propulsion

Legacy systems are toxic, slow, and expensive.

02

Reuse

Every asset launches with a fixed operational life.

03

Reach

The Moon and in-orbit assets stay out of routine reach.

What we do
01

Propulsion

HTP engines for reusable spacecraft.

02

Vehicles

Refuelable vehicles with cislunar range.

03

Logistics

Routing, servicing, and supply across orbits and surfaces.

The hardware

Vehicles for space logistics,
and the propulsion that powers them.

Modern hypergolic propulsion.

A modern alternative to toxic legacy systems, built for repeated operations.

Thrust class 100-500 N
Isp 300 s
Propellant HTP bipropellant
Satellite class >250 kg
Reusable in-space vehicles.

Vehicles built around P78 propulsion. One platform, many missions.
