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.

Nuclear fuel must be of high quality before being placed into service in a reactor. Nuclear fuel vendors currently use manual inspection for quality control of the nuclear fuel pellets before they are inserted into the zirconium fuel rods and bundled into assemblies. The feasibility of automating the pellet inspection process using artificial neural networks is examined to improve accuracy, speed, and cost; to reduce employee radiation doses; and to provide defect statistics to the fuel manufacturer. Sample nuclear fuel pellets (252 pellets) are photographed and scanned, and appropriate feature extraction techniques are developed and applied to the scanned images. The extracted features are then used as inputs to a backpropagation neural network. The results indicate that a backpropagation neural network is capable of classifying pellets as good (passing) or bad (failing) with high accuracy.
