Summary

Story summary

NASA's Dragonfly mission to explore Titan, Saturn's largest moon, is planned to launch in 2028.
Researchers from the University of Illinois Urbana-Champaign found that the atmosphere's composition significantly affects heat shield performance during reentry.
In oxygen-rich environments, heat shields undergo steady ablation, while Titan's nitrogen-rich atmosphere causes unpredictable spallation, ejecting material violently.
These effects pose mission risks by disrupting aerodynamics and endangering the spacecraft.
