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.

A hot-dip process developed in FZK, was applied to produce a hydrogen permeation barrier on MANET steel. The formation of the alumina layer is a two step process. The hot-dip aluminizing method produced first an intermetallic layer of FexAly by immersing the specimens in molten aluminium at 1073 K for 10 min. Secondly, by its exposure to an oxygen containing gas (1223 K, 10 and 30 h) the alumina layer is formed on the intermetallic layer. The last step is to form a fully martensitic phase (δ-ferritic free structure) by a specific heat treatment (1348 K, 30 min fast cool; 1023 K, 2 h).The oxide layer and bulk material were characterized by optical metallography, Vickers microhardness measurements, scanning electron microscope (SEM) with energy dispersive X-ray analysis (EDX), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD) on the surface. A permeation reduction larger than three orders of magnitude was obtained in the sample that has undergone a 30 h exposure in air at 1223 K.
