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.

This paper validates a technique to add statistical noise to a computed radiography (CR) image in order to simulate accurately how the same image would appear if taken at a reduced tube current. To that end, a noise addition simulation software has been developed in order to create lower-dose pediatric CR selecting the desired lower X-ray tube current.The effect of different tube current settings (in milliampereseconds) on image quality has been evaluated using the CDMAM 3.4 phantom, and the obtained results show good agreement between the simulated and real images in terms of noise measurement. The new CR images allow medical researchers to study how lower dose affects the patient diagnosis without taking new images.The developed algorithm will be used in future medical research on determining the minimum tube currents necessary for adequate diagnoses.
