Earthbound air travel can be a hassle, even for careful planners. So if you’re heading to the Moon or beyond, it’s time to shift your planning into hyperdrive. Our advice, when there’s no guidebook, no proven vehicle, and your destination is a moving target? Don’t forget to pack your nuclear power bank.

At the University of Rhode Island, I initially enrolled as a candidate for an accelerated track to earn bachelor’s and master’s degrees in mechanical engineering, with a minor in nuclear engineering. My objective was to concentrate on reactor power design and join efforts to make nuclear energy safer, more efficient, and less stigmatized.
My plans changed after I attended a guest presentation on high-performance nuclear thermal propulsion (HP-NTP) led by Michael Houts, manager of NASA Nuclear Research at Marshall Space Flight Center. He posted his email address on one of the last slides, so I took a chance and contacted him about potential research opportunities and thesis work. As it turned out, that one little email ultimately led to four NASA-sponsored design projects at URI—two are complete, and two are in progress—as well as my thesis. My research has been on HP-NTP, specifically the centrifugal nuclear thermal rocket (CNTR) design. In that design, liquid uranium is heated to extremely high temperatures in a cylinder that is rotated between 5,000 and 7,000 revolutions per minute as liquid hydrogen passes through the center of the cylinder, where it is heated and expanded, exiting as a propellant while the liquid uranium is retained by centrifugal force.
