Stardust is developing a full-stack solution to reflect minute amounts of sunlight: a safe, measurable, adjustable, and fully reversible system to stabilize Earth’s temperature.

Its mission is to develop a real, actionable option to mitigate near-term catastrophic warming.

Stardust particles are made of components which are abundant in nature, chemically inert in the stratosphere, and safe for humans and ecosystems.

The particles naturally return to Earth's surface over time and recycle safely back into the biosphere.​The company is developing a fully-integrated system for tunable deployment that includes high-altitude deployment capability, atmospheric monitoring sensors, and predictive modeling.
