(2009-05-15)The new vision for space exploration will focus on sending humans to the moon and eventually to Mars. This endeavor presents new challenges that are critically different from the past experience with robotic missions to ...
-
(2021-04-22)The United States and other nations plan to return humans to the surface of the Moon in this decade. On the horizon, the United States plans to send humans to the surface of Mars. Multiphase fluid systems, including boiling ...
-
(2018-06-22)The Martian atmosphere is dominated by the presence of irregularly shaped dust aerosols. These aerosols affect the vertical temperature profile and initiate dynamical responses on local, regional, and global scales. In ...
-
(2013-07-22)Martian clouds and dust play an important part of the radiative transfer and energy balance budget. To assist in fully understanding the impact of clouds and dust, the complete diurnal cycle needs to be characterized. One ...
-
(2023-07-24)Lassen Volcanic National Park (LVNP) is composed of a variety of environments such as acid-sulfate, and chloride-rich hot springs, fumaroles, and mud pots. This variation in geochemistry may host a high diversity of ...

(2013-07-10)Uncertainties persist regarding the assessment of the carcinogenic risk associated with galactic cosmic ray (GCR) exposure. The GCR spectrum peaks in the range of 300 MeV/n to 700 MeV/n and is comprised of elemental ions ...
-
(2018-07-17)Although life has existed on earth for at least 3.8 billion years, biogeochemical ‘fossils’ left behind by microbial life before the Great Oxygenation Event are contentious. The Mars 2020 rover will target Noachian age ...
-
(2011-10-21)The sources and sinks of energy for transient waves in the Martian atmosphere are investigated, applying diagnostic techniques developed for the analysis of terrestrial baroclinic waves to output from a Mars General ...
-
(2012-02-14)How the dust cycle works on Mars is a key atmospheric issue, as the dust cycle is arguably the dominant cycle in the current Martian climate. In addition, how much is known about the Martian planetary boundary layer is ...
-
(2012-07-11)Atmospheric opacity, otherwise known as optical depth, is the measurement of the amount of radiation reaching the surface through the atmosphere. The spatial and temporal patterns in optical depth tell us about the aerosol ...
-
(Texas A&M University, 2004-09-30)Rock glaciers play a significant role in the alpine debris transport system. For practical and engineering considerations, identifying the internal structure and its relationship to surface characteristics is significant ...
-
(2017-05-09)Dust aerosols in the Martian atmosphere play a fundamental role in determining the behavior of atmospheric circulations at all spatial scales and are well-known as a tracer of boundary layer dynamics. Vertical variations ...
-
(2017-05-08)Carbonates are found in meteorites collected from Antarctica. The stable isotope composition of these carbonates records their formation environment on either Earth or Mars. The first research objective of this dissertation ...
-
(2016-08-17)Dust in the Martian atmosphere influences energy deposition, dynamics, and the viability of solar powered exploration vehicles. The Viking, Pathfinder, Spirit, Opportunity, Phoenix, and Curiosity landers and rovers each ...
-
(2017-05-09)A comprehensive assessment of the energetics of transient waves is presented for the atmosphere of Mars using the Mars Analysis Correction Data Assimilation (MACDA) dataset (v1.0) and the eddy kinetic energy equation. Each ...
-
(2022-12-09)In order to determine how sediment transport and alteration processes change the composition of sediment relative to source rock, Icelandic, basaltic fluvial and aeolian sediments were analyzed from the Þórisjökull glacial ...
