Bioengineering Branch

Future human missions beyond low Earth orbit will require the development of technologies that minimize launch mass and resupply costs, while providing a high degree of reliability and self-sufficiency. Currently, the Closed-Loop Environmental Control and Life Support System (ECLSS) on the International Space Station (ISS) consists of subsystems that enable humans to live and work in the space environment.

The Bioengineering Branch (SCB) works collaboratively with other NASA centers to maintain the current ECLSS on the ISS. It is also developing the next generation of regenerative technologies to enable humans to live beyond low Earth orbit for extended periods.  Research expertise and technology development areas include atmosphere revitalization and trace contaminant control, water recovery, and logistics reduction including solid waste management, in situ resource utilization, and synthetic biology.

The ongoing research and development efforts are integral to achieving the ambitious goals of space exploration. By pioneering advanced life support systems and biotechnologies, we are paving the way for sustainable human presence beyond low Earth orbit. In addition, these technologies can be transferred to terrestrial applications to enhance life here on Earth.

Logistic Reduction

The Logistic Reduction group is comprised of subject matter experts dedicated to developing technologies for volume reduction, water and other resource recovery, and the microbial and chemical safening and repurposing of waste materials. Recently, the group has begun examining technologies to optimize solid waste processing systems and their conversion for use in various NASA missions, including the Artemis and Mars missions. 

Synthetic Biology

The Synthetic Biology Group engineers biological systems to provide critical resources for space exploration, including food, life support, and materials. Current efforts include BioNutrients,  CO2-based Manufacturing, Lunar Explorer Instrument for space biology Applications (LEIA), and Space Algae.
