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 conceptual designs of the supplemental heating systems for a tenth of a kind, commercial tandem mirror reactor have been developed. A high power ECRH system at 60GHz maintains the thermal barrier in each endcell and a second low power system at 71GHz increases the magnitude of the potential peak. The sloshing ion distribution in the plug is produced by a 475KeV negative ion neutral beam. An ICRH system provides a hot plasma in the anchor region for pressure weighting of the geodesic curvature, thus ensuring stability.
