NASA's Titan Dragonfly will touch down on a field of dunes and shattered ice

It looks like Dragonfly will be searching for organic compounds that could be the seeds for biological life on Titan or at least organic compounds that could lead to abiogenesis in some other environment. Interesting, Titan does not fall within the definition for the CHZ or OHZ. This report shows many large exoplanets now in the CHZ and OHZ where potential exomoons if found, could support life.

CONCLUSIONS In this paper, we present a complete catalog (at time of writing) of planets that orbit within or through the HZ, including the HZ boundaries and the percentage of the orbital period that each planet spends in their star's HZ. Observational metrics for each planet, such as TSM values and RV amplitude, are included to facilitate selection for future follow-up observations."

Here is a report on the HD 45364 system and CHZ and OHZ where possible exomoons could exist and be habitable. New Dynamical State and Habitability of the HD 45364 Planetary System, https://ui.adsabs.harvard.edu/abs/2022AJ....164..163L/abstract

I find it intriguing that astrobiology considers searching for biological life or compounds that could evolve into life on some of the moons of Jupiter or Saturn. These large planets are not in the CHZ or OHZ but exomoons that could be orbiting around giant planets in other star systems in their CHZ or OHZ are considered useful targets for astrobiology studies. It seems we must be flexible in the science modeling for the origin of life, postulated to arise via abiogenesis that could evolve in many different areas and many different conditions.
