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.

Previous experimental work led to the development of a kinetic model that can be used to quantify iodine sorption behavior on a stainless steel surface. The kinetic model, based on the mechanism proposed in earlier work, consists of four chemical reactions. The model has reproduced the time-dependent adsorbed iodine concentration data on the coupons observed under various atmospheric conditions and different cycles of loading and purging. The iodine adsorption kinetics were then incorporated into a mass transport equation to simulate iodine sorption behavior from a flowing air stream through a length of stainless steel tubing. Discussed are the model, the simulation results, and their implications regarding the calibration of iodine transmission through long stainless steel sampling lines used for radiological monitoring of airborne iodine in a reactor containment building following an accident.
