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.

One of the primary objectives of the Tritium Systems Test Assembly is to demonstrate that the technologies associated with the DT fuel cycle for a fusion reactor can be operated safely and operated with minimal environmental impact. During the design and construction phase, safety analyses were performed to investigate the effects of normal operations, of component failure, of operational failures, and of failures induced by natural phenomena. The effects on operation personnel, the general public and the environment were determined. Major releases of tritium were found to be highly improbable (<10−6/year) since they require a compound failure of primary and secondary containment, along with either a breach of the building or a failure of the room cleanup system. The effects from normal operations and high probability failures were also determined to be minimal.
