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.

Two vapotrons from the Joint European Torus (JET) actively cooled divertor design have been fitted by the Japan Atomic Energy Research Institute with unidirectional high-conductivity carbon-fiber-composite tiles and have been tested in the JET Neutral Beam Test Bed. The test section showed excellent uniformity and accepted power densities up to 30 MW/m2 for equilibrium pulses. The surface temperature was 1100°C at 20 MW/m2. One tile detached at a power density of 25 MW/m2. A total of just under 300 pulses at power densities mostly between 20 and 30 MW/m2 have been fired onto the test sections without additional failure. The hydraulic parameters were as follows: water inlet temperature, 15 to 20°C; average water pressure in the component, 0.4 and 0.69 MPa; flow velocity, 6.9 and 7.5 m/s.
