Overview

Spaceium builds fully automated space stations to refuel and repair spacecraft. We have secured $86.1 million in binding commercial contracts and have an additional $230 million in the pipeline. Additionally, we have 1 billion dollars in letters of intent. We have successfully tested our hardware, which will launch to space next year.

Our fully automated space stations will efficiently store and transfer both cryogenic (extremely cold) and non-cryogenic fuels with zero loss during storage and transfer. And they can transfer fuel seamlessly to any spacecraft design using our proprietary modular robotic arm.

Our customers include launch vehicles, orbital transfer vehicles, moon landers, and spacecraft that benefit from increased payload capacity and extended travel capabilities. Our long-term vision is to build service hubs along the space superhighway to connect Earth to Moon and Mars and help humanity to become multi multi-planetary species

Co-Founder & CEO @ Spaceium (S24) I love space and grew up wanting to be an astronaut one day. I co-founded Spaceium to build space infrastructure for a better new space economy. 
 I specialize in orbital mechanics and rocket propulsion systems. Previously, I worked on Aerodynamic models for NASA, built models for interplanetary transfers for an unmanned return mission to an asteroid in real time, and built rocket engines, payload structures, and recovery systems.
