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.

The effective tritium recovery system should be designed to recover tritium from DT reactor blanket sweep gas in a form easy to transfer to the main fuel cycle. The cryosorption method using a porous adsorbent at the temperature of liquid nitrogen is one of the candidate processes for extracting tritium from hydrogen-swamped helium sweep gas because it has advantages of a large recovery capacity of gaseous tritium and good releasability of recovered tritium to the next process. In order to quantify the performance of the cryosorption method in recovering hydrogen isotopes from hydrogen-swamped helium sweep gas flow, the adsorption capacity and separation factor for multicomponent hydrogen isotope mixtures in helium on molecular sieve 4A (MS4A), molecular sieve 5A (MS5A) and activated carbon at 77.4 K were measured.
