We make oxygen from moon dirt!
We're working to eventually become the gas station of the solar system by supplying mission-critical resources to enable the permanent presence of humans on the Moon and beyond.
We believe humanity is ready to return to space and stay there permanently.
With launch platforms like SpaceX Starship, NASA SLS, and Blue Origin New Glenn nearing operational readiness, the next challenge is enabling sustainable presence.
Aster aims to support NASA’s vision of establishing a permanent lunar base within the next decade.
Mini-GRU (Miniature Gas Refinement Unit) is Aster’s custom oxygen production reactor using In-Situ Resource Utilization.
Mini-GRU will generate roughly 0.05 grams of oxygen per second, supporting up to four astronauts simultaneously.
CO₂ scrubbers remove carbon dioxide but do not regenerate oxygen.
The full oxygen recycling process requires significant energy. Because of this, NASA often resupplies oxygen on the ISS by delivering water for electrolysis or high-pressure oxygen tanks.
95% of lunar missions land near the equator where water-ice is scarce.
Aster’s regolith approach allows oxygen generation anywhere on the Moon.
Producing oxygen for one astronaut via water-ice requires processing more than two dump trucks of regolith.
Aster’s reactor requires only the volume of a small watermelon.
