A youthful Titan implied by improved impact simulations
Shigeru Wakita, Brandon C. Johnson, Jason M. Soderblom +1
The small number of impact craters found on Titan suggests that its surface is relatively young. Previous work estimated its surface age to be between 200 and 1000 Myr. This estima…
Impacts into Titan's methane-clathrate crust as a source of atmospheric methane
Shigeru Wakita, Brandon C. Johnson, Jason M. Soderblom +5
Titan is the only icy satellite in the solar system with a dense atmosphere. This atmosphere is composed primarily of nitrogen with a few percent methane, which supports an active,…
Modeling the formation of Selk impact crater on Titan: Implications for Dragonfly
Shigeru Wakita, Brandon C. Johnson, Jason M. Soderblom +3
Selk crater is an 80 km diameter impact crater on the Saturnian icy satellite, Titan. Melt pools associated with impact craters like Selk provide environments where liquid w…
Methane-saturated layers limit the observability of impact craters on Titan
Shigeru Wakita, Brandon C. Johnson, Jason M. Soderblom +2
As the only icy satellite with a thick atmosphere and liquids on its surface, Titan represents a unique end-member to study the impact cratering process. Unlike craters on other Sa…
Science goals and new mission concepts for future exploration of Titan's atmosphere geology and habitability: Titan POlar Scout/orbitEr and In situ lake lander and DrONe explorer (POSEIDON)
Sébastien Rodriguez, Sandrine Vinatier, Daniel Cordier +61
In response to ESA Voyage 2050 announcement of opportunity, we propose an ambitious L-class mission to explore one of the most exciting bodies in the Solar System, Saturn largest m…
The Case for Non-Cryogenic Comet Nucleus Sample Return
Keiko Nakamura-Messenger, Alexander G. Hayes, Scott Sandford +22
Comets hold answers to mysteries of the Solar System by recording presolar history, the initial states of planet formation and prebiotic organics and volatiles to the early Earth.…
