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.

Fusion reactor blankets based on an aqueous slurry concept are proposed and examined. Attractive features and disadvantages of aqueous slurries as blankets are reviewed. Calculations to determine the capacity of slurry particles with different diameters to stop recoiling tritons are described. Neutronic calculations are performed to specify slurry blankets that are composed of LiF spherical particles suspended in both light and heavy water. Zircaloy and stainless steel are studied as vacuum wall and structure materials for the slurry designs. It is determined that aqueous slurry blankets are probably capable of breeding tritium (based only on the tritium produced and retained in the solid particles) and are worthy of additional study.
