At Interstellar Lab, our mission is to build a future full of life, on Earth and beyond.
We believe in a world where technology enables humans to live in harmony with nature, where biodiversity thrives and expands, and
where terrestrial life becomes multi-planetary.
To build this future, we design autonomous biospheric systems to grow plants with precision, on Earth and in Space. Our AI-powered
BioPods and BioCapsules leverage biosciences to reproduce and optimize growth conditions for a wide variety of high-value plants.
On Earth, we pioneer molecular and biofarming, boosting the production of metabolites and bioactive compounds while offering
sustainable, traceable, and high-quality natural ingredients to the beauty, fragrance, pharmaceutical, and nutraceutical
industries.
In space, we collaborate with agencies and private companies to develop biofarming units that advance life science research in
microgravity and lay the foundation for future biofactories in space, enabling innovative terrestrial applications and
long-duration space missions.
