Potential NASA Commercial Applications: NASA applications include missions to remote locations and orbits where there is a low level of solar input. Low intensity sunlight affords the benefit of a lower rejection temperature and improved cryocooler performance, for the same cold end temperature, and permits a decrease in system size and power draw. Only a third the power draw is predicted for the 35-K cold end case. Serendipitously, this agrees well with the drop in power generation due to dim solar light on remote missions. Taken together, the effects favor employing smaller cryocooler systems specifically designed for reduced rejection temperatures and system envelopes.
