What is Momentus?

Momentus is a space infrastructure company focused on providing in-space transportation and other services. Their primary technology involves using water plasma propulsion systems (microwave electrothermal thrusters or MET) to move satellites between different orbits after they've been initially deployed. This allows for more flexible satellite deployment, optimized orbits, and extended mission lifespans. They aim to become a key player in the space logistics and infrastructure market.
