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.

A 1000-MW(electric) fusion power reactor concept based on electrochemically induced D-Dn, D-Dp, and deuterium-tritium reactions is presented. A D- He reaction is not possible because He is not absorbed in the electrode. The concept of a tube-type fuel cell is presented. The inner surface of the tube is laminated with palladium. The cell provides a large cathode surface and efficient heat transport to the water coolant. The fuel assemblies and bundles of fuel tubes are installed in the pressure vessel. The reactor system is very similar to a pressurized water reactor, though the reactor internals are much simplified due to the elimination of fission fuel pellets and control rods. The spatial power distribution of the reactor core is very flat compared with that of fission reactors.
