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 effects of incorporating additional qualities of insoluble dissolution fines containing noble metals together with the fission product feed solutions were investigated for application to the French T7 vitrification facility at La Hague. Three types of tests were conducted: nonradioactive laboratory tests, radioactive laboratory tests, and industrial-scale tests in a prototype vitrification unit. The laboratory test results showed that the quality of R7T7 glass containing from 1.5 to 4 wt% of platinoids is fully equivalent to that of standard R7T7 glass without platinoids. These findings were confirmed on glass casting samples containing 0 to 3 wt% of platinoids from a full-scale industrial vitrification prototype facility. Recent tests in which video cameras have been used to visualize the molten glass and model simulations of glass properties and of melting pot behavior suggest that industrial operating conditions can be optimized to produce glass with platinoid concentrations approaching this limit value.
