Impossible Sensing

Impossible Sensing is a St. Louis, Missouri-based optical sensing technology company that develops advanced field-deployable sensors for chemical, biological, and environmental analysis. The company's core technology centers on portable Raman spectroscopy and related optical sensing approaches that bring laboratory-grade analytical capability into extreme environments — from deep ocean floor to space.

For space applications, Impossible Sensing develops instruments designed for planetary science and in-situ resource utilization (ISRU) — enabling chemical analysis of extraterrestrial surfaces, atmospheres, and materials. Their compact optical sensors are designed to operate in radiation-exposed, low-power, and mass-constrained spacecraft and lander environments.

The company has been involved in NASA-funded research for developing next-generation Raman spectrometers and optical sensing instruments for planetary exploration. Their approach focuses on making advanced optical sensing accessible outside the laboratory, enabling scientific measurements that were previously impossible in remote or extreme field conditions.
