NASA's Technology Transfer Program is seeking inquiries from companies interested in obtaining licensing rights for the Passive Porous Tube Nutrient Delivery System (KSC-TOPS-73), a technology designed to enhance plant growth in microgravity environments. This innovative system addresses the challenges of delivering air, water, and nutrients to plant roots without the need for active pumping, which is currently required in existing methods used on the International Space Station. The licensing rights may be granted on either an exclusive or nonexclusive basis, and interested parties can submit their applications through NASA’s Automated Technology Licensing Application System (ATLAS) at the provided link. It is important to note that NASA does not provide funding in conjunction with these licenses, and no follow-on procurement is expected from this notice. For further inquiries, companies can contact NASA’s Technology Transfer Program via email at Agency-Patent-Licensing@mail.nasa.gov.
