Significance of Specific Force Models in Two Applications: Solar Sails to Sun-Earth L4/L5 and GRAIL Data Analysis Suggesting Lava Tubes and Buried Craters on the Moon
In the trajectory design process, gravitational interaction between the bodies of interest plays a key role in developing the over-arching force model. However, non-gravitational forces, such as solar radiation pressure (SRP), can significantly influence the motion of a spacecraft. Incorporating …

High-Fidelity Gravity Modeling Applied to Spacecraft Trajectories and Lunar Interior Analysis
… and extent of subsurface features, such as empty lava tubes beneath the mare surface. In addition to their importance for understanding the emplacement of the mare flood basalts, open lava tubes are of interest as possible habitation sites safe from cosmic radiation and micrometeorite impacts. …

Hydrogeomorphology of Lava Rise Pits in The Laki Lava Field, Southeast Iceland
Lava Rise Pits (LRPs) are found within the Laki lava field in Southern Iceland. LRPs naturally occur in pahoehoe lava flows and form when the flow in lava tubes ceases and collapses. The goal of this study was to better understand the hydrogeomorphology of LRPs during the Fall-winter season. Three …

The geophysical evolution of impact basins and volcanic structures on Mercury and the Moon
… and that the tremendous sizes at which lunar lava tubes can be stable open up both new ways of interpreting GRAIL observations of the lunar gravity field and new possibilities for human exploration of the Moon.</p>

Systematics of the Subterranean Amphipod Genus <i>Stygobromus</i> (Crangonyctidae) in Western North America, With Emphasis on Species of the <i>Hubbsi</i> Group
… may not be older than the Pleisiocene. Some lava tubes in Oregon and Washington are even more recent. This explanation may also account for close morphological similarity of <em>hubbsi</em> group species in western North America.</p>

Meccanismi di formazione dei tubi di lava
… proposed to describe two different mechanisms of lava tubes formation. A first model is introduced to describe the development of a solid crust in the central region of the channel, and the formation of a tube when crust widens until it reaches the leve\'es. The Newtonian assumption is considered …
