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 influence of the gaseous atmosphere inside the installation for microsphere production on the quality of the microsphere surface is discussed. The heat-exchange environment of a furnace controls the rate of heating of the initial granules, the character of the interaction of the viscous gas environment with the falling liquid hollow sphere, and the rate of cooling of the resultant microsphere. For an Ar:He mixture of gases it is shown experimentally that the change of the component percentage of the gas mix results in a different character in the surface quality of the obtained microspheres. Regions of gas mixture composition are found where the surfaces of polystyrene or glass microspheres have no characteristic defects. These compositions are not the same for glass and polystyrene. We present a physical explanation of these observations.
