The influence of upper boundary conditions on molecular kinetic atmospheric escape simulations
S. R. Carberry Mogan, O. J. Tucker, R. E. Johnson
Molecular kinetic simulations are typically used to accurately describe the tenuous regions of the upper atmospheres on planetary bodies. These simulations track the motion of part…
A tenuous, collisional atmosphere on Callisto
Shane Carberry Mogan, Orenthal Tucker, Robert Johnson +7
A simulation tool which utilizes parallel processing is developed to describe molecular kinetics in 2D, single-and multi-component atmospheres on Callisto. This expands on our prev…
Persephone: A Pluto-System Orbiter and Kuiper Belt Explorer
Carly Howett, Stuart Robbins, Bryan J. Holler +40
Persephone is a NASA concept mission study that addresses key questions raised by New Horizons' encounters with Kuiper Belt objects (KBOs), with arguably the most important being "…
On the Effect of Magnetospheric Shielding on the Lunar Hydrogen Cycle
Orenthal J. Tucker, William M. Farrell, Andrew R. Poppe
We examine how water is produced globally over the lunar surface as it orbits in/out of the magnetotail. Due to the interaction of the solar wind (SW) with Earth's magnetic field,…
Lifetime of a transient atmosphere produced by Lunar Volcanism
Orenthal J. Tucker, Rosemary M. Killen, Robert E. Johnson +1
Early in the Moon's history volcanic outgassing may have produced a periodic millibar level atmosphere (Needham and Kring, 2017). We examined the relevant atmospheric escape proces…
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…
