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.

All nuclear plant instrumentation connected at installation points to low-voltage power circuits will be exposed to electric fast transients induced by power switching and lightning. Unwarranted interruption of instrumentation due to transients may result in serious loss through bothersome activation of a plant's engineering safeguards. In this study, in situ responses of a digital wide-range neutron monitor is studied in terms of real-time disturbances during electric transients. Using correlation analysis, a systematic methodology between transient responses and steady-state electromagnetic emission spectra has been developed and justified to be useful for transient isolation. Moreover, results of various on-site approaches to improve the electromagnetic compatibility of safety-related instrumentation are discussed.
