NERVA kam über einige Bodentests auf dem Atombombentestgelände in Nevada nicht hinaus. Die Nixon-Regierung beschnitt das Budget des Projektes dramatisch, als Anfang der 1970er Jahre das öffentliche Interesse an der Raumfahrt nach der letzten Mondlandung 1972 zurückging. Nachfolgeprogramm war das 1992 eingestellte Projekt Timberwind.

Spinal disc herniation pressing on one of the lumbar or sacral nerve roots is the most frequent cause of sciatica, being present in about 90% of cases. This is particularly true in those under age 50. Disc herniation most often occurs during heavy lifting. Pain typically increases when bending forward or sitting, and reduces when lying down or walking.
