Experimental Characterization of the Pyridine:Acetylene Co-crystal and Implications for Titan's Surface
Ellen C. Czaplinski, Tuan H. Vu, Morgan L. Cable +3
Titan, Saturn's largest moon, has a plethora of organic compounds in the atmosphere and on the surface that interact with each other. Cryominerals such as co-crystals may influence…
CO2-driven surface changes in the Hapi region on Comet 67P/Churyumov-Gerasimenko
Björn J. R. Davidsson, F. Peter Schloerb, Sonia Fornasier +24
Between 2014 December 31 and 2015 March 17, the OSIRIS cameras on Rosetta documented the growth of a 140m wide and 0.5m deep depression in the Hapi region on Comet 67P/Churyumov-Ge…
Operations for Autonomous Spacecraft
Rebecca Castano, Tiago Vaquero, Federico Rossi +20
Onboard autonomy technologies such as planning and scheduling, identification of scientific targets, and content-based data summarization, will lead to exciting new space science m…
Vertical compositional variations of liquid hydrocarbons in Titan's alkanofers
Daniel Cordier, David A. Bonhommeau, Tuan H. Vu +2
According to clues left by the Cassini mission, Titan, one of the two Solar System bodies with a hydrologic cycle, may harbor liquid hydrocarbon-based analogs of our terrestrial aq…
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.…
The Science Case for a Titan Flagship-class Orbiter with Probes
Conor A. Nixon, James Abshire, Andrew Ashton +36
We outline a flagship-class mission concept focused on studying Titan as a global system, with particular emphasis on the polar regions. Investigating Titan from the unique standpo…
AMBITION -- Comet Nucleus Cryogenic Sample Return (White paper for ESA's Voyage 2050 programme)
D. Bockelée-Morvan, G. Filacchione, K. Altwegg +27
This white paper proposes that AMBITION, a Comet Nucleus Sample Return mission, be a cornerstone of ESA's Voyage 2050 programme. We summarise some of the most important questions s…
No compelling evidence for clathrate hydrate formation under interstellar medium conditions over laboratory timescales
Mathieu Choukroun, Tuan H. Vu, Edith C. Fayolle
A recent article reported experimental observations of methane and CO2 clathrate formation at conditions similar to the interstellar medium (ISM), namely 10-30 K and 10-10 mbar. Th…
The Rosetta mission orbiter Science overview the comet phase
M. G. G. T. Taylor, N. Altobelli, B. J. Buratti +1
The International Rosetta Mission was launched in 2004 and consists of the orbiter spacecraft Rosetta and the lander Philae. The aim of the mission is to map the comet 67P Churyumo…
Equilibrium composition between liquid and clathrate reservoirs on Titan
Olivier Mousis, Mathieu Choukroun, Jonathan I. Lunine +1
Hundreds of lakes and a few seas of liquid hydrocarbons have been observed by the Cassini spacecraft to cover the polar regions of Titan. A significant fraction of these lakes or s…
A Hot Gap Around Jupiter's Orbit in the Solar Nebula
N. J. Turner, M. Choukroun, J. Castillo-Rogez +1
The Sun was an order of magnitude more luminous during the first few hundred thousand years of its existence, due in part to the gravitational energy released by material accreting…
