It was a pleasure visiting the DOE @ENERGY at Oak Ridge National Laboratory @ORNL and watching the team at work. Oak Ridge plays a central role in producing the Pu-238 that fuels the RTGs and RHUs NASA relies upon for deep-space science missions. Similar to NASA, you cannot walk through these facilities without developing an extreme appreciation for what engineers achieved decades ago, often with little more than a slide rule. There are reactors and facilities first brought online in the 1960s that still provide capabilities extraordinarily difficult and expensive to replicate today. It is another reminder that previous generations knew how to take on the hard problems, the big bold endeavors, and deliver lasting outcomes. With the support of POTUS and the National Space Policy, @NASA will inevitably pursue more fission-powered missions beyond SR-1 Freedom. We will keep pushing the limits of materials science, operating reactors at higher temperatures and with greater autonomy, improving power-conversion efficiency, and enabling missions throughout the outer solar system. SR-1 is just the beginning of the “Nuclear NASA”. We are grateful to @SecretaryWright, @NNSAWilliams, and congressional leadership for working alongside NASA to make this next 'giant leap' capability possible.
