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.

Damage caused by neutrons in the first wall of fusion reactor is studied in detail for two different structural materials (Type 316 stainless steel and Nimonic PE-16) in the Princeton fusion power plant design. The first-wall neutron spectrum is calculated by the ANISN code, and a dosimetric analysis is performed for both materials. Moreover, a complete study of damage (swelling and creep) during reactor life is done for Type 316 stainless steel. On the basis of a 1% creep strain, the lifetime of a Type 316 stainless steel first wall is calculated to be ∼2 yr, compared with the ∼22-yr lifetime obtained for Nimonic in the Princeton design. In this way, the economic advantage of a superalloy, compared to stainless steel, has been confirmed.
