Key Benefits

The high-performance engine enables the design of a small and lightweight Orbital Transfer Stage (OTS) due to both its performance and the high bulk density of LOX/LNG fuel, which is over twice that of LOX/LH2 fuels. This level of performance and dense propellants allow delivery of a reliable, long-life, light-weight, and low-cost OTS with key performance parameters:

• Powered by a high-performance full-flow staged combustion engine.

• Throttleable from 30% to 100% thrust.

• Autogenous pressurization with unlimited zero-g restarts. 

• Access to all cislunar orbits.

Applications

NASA

Mjölnir has the potential to be an expendable NASA OTS evolving into a lunar lander and a fully reusable OTS. From LEO a 3,000 lb gross OTS can deploy a 400 lb payload to GEO and over 200 lbs to any location in cislunar space, including Earth escape velocity. 

​

Military

A 3,000 lb OTS also has potential military applications by enabling responsive military space domain awareness throughout cislunar space.

​

Commercial

The OTS has a small form factor optimized for launch inside the fairing of venture-class vehicles.

​

The Mjölnir engine will be available for OTS, lunar lander, or related capabilities in 2024.
