Special Notice: NATIONAL AERONAUTICS AND SPACE ADMINISTRATION is seeking inquiries from companies interested in obtaining license rights to commercialize, manufacture, and market cryogenic selective surfaces. These surfaces, developed as thermal control coatings, have the potential to reflect essentially all solar radiation in the space environment. They can be used to keep cryogenic fuel and oxidizers cold enough for long-term storage in space and support the operation of low-temperature devices and systems on spacecraft. Interested parties can submit a license application through NASA's Automated Technology Licensing Application System (ATLAS). For more information, visit the NASA Technology Transfer Portal. No follow-on procurement is expected from this notice.
