Regolith penetration for placing instruments into ground and regolith-sampling for re-entry or
in-situ analysis play an extremely critical role in searching for alien life and revealing the …

Early Mars climate research has well-defined goals (MEPAG 2018). Achieving these goals
requires geologists and climate modelers to coordinate. Coordination is easier if results are …

Areally extensive exposures of intact olivine/pyroxene‐enriched rock, as well as feldspar‐
enriched rock, are found in isolated locations throughout the Martian highlands. The …

A morphometric and morphologic catalog of~ 100 small craters imaged by the Opportunity
rover over the 33.5 km traverse between Eagle and Endeavour craters on Meridiani Planum …

Aeolian processes have likely been the predominant geomorphic agent for most of Mars'
history and have the potential to produce relatively young exposure ages for geologic units …

Orbitally derived thermal inertia (TI) values of surfaces allow for remote interpretation of rock
and sediment physical characteristics. The evolving local times of the Mars Odyssey …

In recent years, small celestial bodies (SCBs) exploration missions have attracted extensive
attention. For the purposes of space resource exploitation and earth defense, revealing the …

Measuring the physical properties of geological materials is important for understanding
geologic history. Yet there has never been an instrument with the purpose of measuring …

Abstract Using the Mars Exploration Rover Opportunity, we have compiled one of the first
field geologic maps on Mars while traversing the Noachian terrain along the rim of the 22 km …

Interactions between clasts in pyroclastic density currents (PDCs) generate volcanic ash that
can be dispersed to the atmosphere in co-PDC plumes, and due to its small size, is far …
