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.

Time-dependent neutronics analysis for the ferritic steel first wall of the HIBALL heavy ion beam fusion reactor conceptual design is presented. Neutron target interactions that lead to spectrum softening and neutron multiplication are accounted for. The time-of-flight (TOF) spread of neutrons within each energy group is considered. Neutron slowing down in the INPORT first-wall protection system, which is similar to the HYLIFE concept, is found to significantly affect the time over which the damage occurs in the first wall. In the case of an unprotected wall, the time spread is determined primarily by the TOF spread. The INPORT concept is found to significantly reduce both average and peak instantaneous rates of displacements per atom, helium production, and energy deposition in the first wall.
