Volatile-rich impacts on nominally airless solar system bodies such as the Moon can give rise to collisional, transient atmospheres, traces of which may be preserved at cold, permanently shadowed regions near the lunar poles. Understanding the physic
The two-phase water plumes arising from the Enceladus South pole and extending hundreds of km from the moon are a key signature of what lies below the surface. Multiple Cassini instruments measured the gas-particle plume over the warm Tiger Stripe re

The Moon and other virtually airless bodies provide distinctive environments for the transport and sequestration of water and other volatiles delivered to their surfaces by various sources. In this work, we conduct Monte Carlo simulations of water va

The New Horizons flyby of the Jovian system yielded multiple images of the erupting Pele-class volcanic plume, Tvashtar. These images include a unique five-frame sequence or “movie” taken over 8 min that revealed short-term dynamical activity in

A novel computational technique was used to simulate eruptions from Io's Tvashtar Catena region to better understand the origin of the visible structure of the gas/particulate plumes observed by the New Horizons spacecraft in its 2007 flyby of the Jo

Io’s volcanic plumes are the ultimate source of its SO2 atmosphere, but past eruptions have covered the moon in surface frost which sublimates in sunlight. Today, Io’s atmosphere is a result of some combination of volcanism and sublimation, but i

We apply the direct simulation Monte Carlo rarefied gas dynamic technique to simulations of Pluto's rarefied upper atmosphere motivated by the need to better understand New Horizons (NH) data. We present a novel three-dimensional DSMC model of the at

Since its discovery, the Enceladus plume has been subjected to intense study due to the major effects that it has on the Saturnian system and the window that it provides into the interior of Enceladus. However, several questions remain and we attempt

A computational investigation of the physics of water vapor plumes on Europa was performed with a focus on characteristics relevant to observation and spacecraft mission operations. The direct simulation Monte Carlo (DSMC) method was used to model th

When the exhaust plume from a descent engine impinges on the lunar surface, loose regolith can erode and become entrained into a high-velocity spray. These processes are simulated in this work by several integrated models: a hybrid continuum–kineti
