Today’s Pathfinder episode features AstroForge cofounder and CEO Matt Gialich. The CA-based startup is developing technology to mine asteroids for platinum group metals. The company plans to use an uncrewed spacecraft to extract and refine the metals directly on the asteroid before returning to Earth with a sellable metal.

Why platinum? The platinum group metals have unique physical and chemical properties that make them critical to everything from catalytic converters to electronics. According to Gialich, the US has a dwindling supply of platinum group ore reserves, and Russia and China control a significant supply of global stocks. But there’s hope in the heavens: a single one-kilometer-diameter M-type (primarily composed of metallic iron and nickel) asteroid could contain more platinum than has been mined in the history of humanity, Gialich said.

So far…AstroForge launched a refinery demo this spring and plans to launch a prospecting mission in October where they will physically go to an asteroid to map and monitor the surface. Future missions will include excavation and finally mining.

A sneak peek…Mo and Matt discuss:

The history of landing on asteroids
The basics of asteroid mining
The economics of mining off-planet
Legal and regulatory considerations

And much more…
