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.

Packed-column experiments with iron dust of 40 to 60 mesh (Fisher 1–57) showed an excellent uptake of pertechnetate ions from alkaline (pH ∼ 8.5) high-nitrate (100 to 250 g/ℓ) solutions at flow rates measured in bed volumes (BVs) of between 0.05 and 0.15 BV/min. The columns worked well until they became plugged by rusting after several hundred bed volumes of solution were flowed through (330 to 900 BV). Similar tests using organic ion-exchange resins, such as Dowex SRB-OH and Reillex HP and Reillex HPQ, and the same alkaline high-nitrate solutions showed breakthroughs after 20 to 50 BV were passed.
