Completed TRL 3 (started at 2, targeting 3)
The need for reliable, high capacity, radiation tolerant nonvolatile memory exists in many Human space flight applications. Most projects rely on COTS hardware for a data storage system with very little assurance of radiation performance. The goal of this idea is to develop a high capacity nonvolatile memory system that is radiation tolerant. The concept uses commercially available nand-flash devices that are built with certain radiation immunity. To enhance radiation performance this concept incorporates error detection and correction. The concept is based on technology already explored by the Advanced Space Suit project. The purpose is to complete the work already started by the Advanced Space Suit project using available components. The first phase will prototype a design of the nand-flash memory array board interfaced to the error detection and correction algorithm implemented on an FPGA development board. Radiation testing will be performed by the JSC EV-5 radiation group.
Reliable, high capacity, radiation-tolerant nonvolatile memory is needed in many space applications such as: TA04 Robotics, Tele-Robotics, & Autonomous Systems; TA05 Communications & Navigation; TA07 Human Exploration Destination Systems; TA06 Human Health, Life Support, & Habitation Systems; TA09 Entry, Descent, & Landing Systems
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
