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 modules of a low impedance electron-beam (e-beam) machine were developed to pump a 200-J, 70-ns KrF laser from both sides. The laser was designed as the power amplifier of a picosecond, terawatt excimer laser system, which will be applied to a basic physical research on extreme ultraviolet lasers. Each driving circuit of the e-beam diode was a 2.8.-Ω double parallel plate Blumlein with a 500-kV rail gap as the main switch. The energy deposited in the 42-ℓ laser gain region was measured by several diagnostics to determine the energy transfer efficiency and the spatial uniformity of energy deposition with the guide magnetic field of 1 kG. The triggered operation of 500-kV rail gaps, which is essential for amplifier system synchronization, was realized by the ultraviolet laser irradiation along the rail-gap axis with reduced switching time and jitter of 20 and 1.9 ns, respectively.
