This is a stand for a 1:72 scale model of the National Aeronautics and Space Administration's Nova rocket. The Nova was originally proposed as the first launch vehicle for lunar landing missions. After production of the Saturn V began to perform that mission, a more powerful Nova was proposed to be a follow-on to launch crewed missions to Mars. However, no Nova progressed beyond the design stage. The manufacturer and donor of the model and stand are unknown.
