We investigated the feasibility of using carbon nanotube (CNT) technology for applications in extreme radiation environments that can be encountered in NASA missions. Total ionizing dose (TID) experiments, carried out to 10 Mrad doses, revealed high radiation immunity of the CNT technology. The failure mechanisms were identified and attributed to the CMOS elements and not to the CNT technology itself. With known ''hard-by-design'' methods, CNT technology can be successfully used to >10 Mrad TID.
