Stabilizing Earth’s temperature is possible

Stardust was founded on the belief that humanity’s best days don’t have to be behind us,  and that we have the ingenuity to protect the planet we call home.

Temperatures continue to climb, bringing more extreme weather, mass migration, crop failures, and resource conflicts. These are not distant projections. They are unfolding now, accelerating faster than our capacity to respond.

Humanity needs a different solution

Humanity needs a different solution

One that works at a planetary scale. One that can be deployed this decade, not in some distant future. One that buys us time and protects us from overheating.

Throughout all of human history, we have stewarded and shaped our environment and built a world that could sustain billions of people. Humanity fixed the ozone hole, eradicated diseases, and built systems that transformed the world.

The Earth

Proven by nature, perfected by science

Sunlight Reflection Technology (SRT) applies a natural atmospheric process by introducing safe particles into the very high atmosphere to reflect a small portion of sunlight, helping stabilize rising temperatures in a safe, controlled, and reversible way.

Blue Sky

Built on scientific rigor

Our team spans atmospheric physics, chemistry, materials science, aerospace engineering, and environmental policy. Key findings will be published in peer-reviewed literature with our academic collaborators. Our work is grounded in responsible development,  built in partnership with scientific and governance experts to ensure this technology serves humanity, not just those who build it.

The Earth

A responsible approach is essential

The work we do is grounded in our founding mission: to advance the responsible development of sunlight reflection technology. In partnership with external scientific and governance experts, we’ve been developing a set of principles to guide our work and decision-making.
