Prokaryotic life has dominated most of the evolutionary history of our planet, evolving to
occupy virtually all available environmental niches. Extremophiles, especially those thriving …

NASA's Dragonfly mission will send a rotorcraft lander to the surface of Titan in the mid-
2030s. Dragonfly's science themes include investigation of Titan's prebiotic chemistry …

Titan, the largest satellite of Saturn, is the only one in the solar system with a dense
atmosphere. Mainly composed of dinitrogen with several% of methane, this atmosphere …

Recognizing whether a planet can support life is a primary goal of future exoplanet spectral
characterization missions, but past research on habitability assessment has largely ignored …

We present a one-dimensional coupled ion-neutral photochemical kinetics and diffusion
model to study the atmospheric composition of Titan in light of new theoretical kinetics …

With the exception of in situ atmospheric probes, the most useful way to study the
atmospheres of other planets is to observe their electromagnetic spectra through remote …

A global-mean model of coupled neutral and ion chemistry on Titan has been developed.
Unlike the previous coupled models, the model involves ambipolar diffusion and escape of …

The Electron Spectrometer (ELS), one of the sensors making up the Cassini Plasma
Spectrometer (CAPS) revealed the existence of numerous negative ions in Titan's upper …

The discovery of large (> 100 u) molecules in Titan's upper atmosphere has heightened
astrobiological interest in this unique satellite. In particular, complex organic aerosols …

The photochemistry of N 2 and CH 4 in the atmosphere of Titan leads to a very rich
chemistry which is not well understood. The aim of our study is to improve our understanding …
