Dragonfly, a Pu-fueled drone heading to Titan, gets key NASA approval
Curiosity landed on Mars sporting a radioisotope thermoelectric generator (RTG) in 2012, and a second NASA rover, Perseverance, landed in 2021. Both are still rolling across the red planet in the name of science. Another exploratory craft with a similar plutonium-238–fueled RTG but a very different mission—to fly between multiple test sites on Titan, Saturn’s largest moon—recently got one step closer to deployment.
On April 25, NASA and the Johns Hopkins University Applied Physics Laboratory (APL) announced that the Dragonfly mission to Saturn’s icy moon passed its critical design review. “Passing this mission milestone means that Dragonfly’s mission design, fabrication, integration, and test plans are all approved, and the mission can now turn its attention to the construction of the spacecraft itself,” according to NASA.

The FUSECRAC code, a modification of the CRAC code, was developed to estimate public health effects from released fusion radioactivity both for safety studies and for comparison of the hazards associated with candidate structural materials. This paper summarizes the key motivations, problems, and results of the FUSECRAC comparison. The evolving CRAC code is a product of the Reactor Safety Study and represents the state of the art in fission accident consequence assessments. It was found that potential public health effects from accidental releases of 316 SS are two orders of magnitude higher than from V-15Cr-5Ti or TZM per unit volume of activated first wall released. The probabilities for releases among these materials were not addressed here.
