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.

Over the past decade there has been a growing interest in the application of a class of gaseous radiation detectors, known generally as micropatterned devices, for radiation protection dosimetry and monitoring. The purpose of this paper is to review the features of micropatterned devices that make them of particular interest and to report on some of the successful applications in radiation protection dosimetry and monitoring of instruments based on these detectors.Micropatterned devices, originally developed within the high-energy physics research community, are of several different types and design. The principal devices that have found application in radiation protection measurement science are gas microstrip detectors, gas electron multipliers, and micromesh gaseous structures. The operation of these devices will be reviewed along with modifications that have been carried out to make them suitable for radiation monitoring and microdosimetry.
