Summary

Story summary

Titan may not have an underground ocean, according to Cassini data showing Titan loses 3 to 4 terawatts of heat.
The study led by Flavio Petricca at NASA's Jet Propulsion Laboratory finds Titan's interior consists of thick ice above a rocky core with water pockets.
Surface temperatures reach -290°F, limiting life despite freshwater pockets.
NASA's Dragonfly mission is planned for July 2028 to explore these findings.
