Paragon Space Development Corporation

Paragon Space Development Corporation is a Tucson, Arizona-based aerospace engineering company specializing in environmental control and life support systems (ECLSS), thermal control, and fluid systems for human spaceflight and robotic space missions. Founded in 1993 by former University of Arizona and Biosphere 2 researchers, Paragon brings deep expertise in closed-loop life support technologies that keep humans alive in the harsh environment of space.

Paragon's portfolio spans the design of water recovery systems, carbon dioxide removal systems, thermal radiators, and integrated ECLSS for spacecraft and habitat applications. The company has contributed to ISS systems, NASA's Orion spacecraft, commercial crew vehicles, and lunar surface habitat concepts. Paragon also develops life support for spacesuits — a critical capability as NASA and commercial operators develop next-generation EVA suits for ISS maintenance and lunar surface operations.

As humanity prepares to return to the Moon and eventually travel to Mars, Paragon's expertise in regenerative life support — systems that recycle water, oxygen, and manage thermal loads for long-duration missions — positions the company as an essential partner for deep space human exploration. Paragon's work ensures that crews can survive and thrive far beyond Earth's protective environment.
