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 study was conducted to establish the tasks and special equipment required to remove and replace a Toroidal Field (T.F.) coil from the FED baseline configuration and to identify critical design features which might require improvement to facilitate maintenance procedures. It was established that nineteen major tasks must be accomplished prior to T.F. coil removal. Four of these tasks were identified as major problem areas of such magnitude that design reconsideration is mandatory if T.F. coil removal and replacement is to be a viable option. Specific recommendations are made to alleviate difficulties and enhance FED maintainability.
