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.

Damping of small-scale fast magnetosonic waves (FMSWs) in large tokamak plasmas due to cyclotron absorption by a small group of resonance alpha particles (products of the thermonuclear fusion) is determined on the basis of a nonlocal approach. Such a nonlocal approach for the separate modes of a FMSW gives the same expression for the damping coefficient (except for special cases) as obtained in the local approach, although the distribution of high-frequency fields in the cyclotron resonance range may differ greatly. The cyclotron absorption of these waves by alpha particles may be essential, and it competes with electron Cherenkov absorption and cyclotron absorption by ions of other species during plasma heating and maintenance of the current in reactor tokamaks by means of FMSWs.
