Polar water ice clouds and dust aerosols seasonal mapping using CRISM EPF data

Thursday, July 21 2011 - 2:17 pm, PDT
We propose to use Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) emission phase function (EPF) measurements in the Martian poles (regions poleward of 55° latitude) to map dust and water ice aerosols and surface albedos as a function of season using CRISM data.

Analysis of Phoenix Optical Microscopy Images to Understand Soil Processes on Mars

Wednesday, May 18 2011 - 4:44 pm, PDT
We plan a systematic study of the Phoenix OM images with the objective of better understanding the geology producing these grain morphologies in the northern plains of Mars.

Mars Simulation Measurements (MSM): Survivability of Organic Molecules Adsorbed on or Occluded in Minerals under Ionizing Radiation

Friday, September 10 2010 - 2:37 pm, PDT
This proposal requests funds to determine the protective role of minerals on adsorbed organic molecules against radiation effect under conditions that simulate Mars environments. Organic material could have been delivered to Mars from space via meteorites, comets and small interplanetary dust particles. Endogenous formation of organic material may also be considered as a possibility.

Dune Morphology and Atmospheric Models: Implications for Present-Day Martian Aeolian Activity

Monday, August 16 2010 - 3:56 pm, PDT
It has long been unclear whether the many sand dune fields on Mars are actively evolving in the present climatic era. Recent evidence of sand avalanching and active sustained saltation has been identified in high resolution images. In particular, we report the first clear indications of ripple migration over dark dune slopes observed from orbit. We propose a comprehensive study that will specifically address this knowledge gap, via the careful analysis of high-resolution spacecraft imagery over the majority of the planet (between 60° N and 60° S). In fact, even the preliminary investigation of a small sampling of such imagery has already yielded evidence of recent sand avalanching on dark dune slip faces and the first clear indications of ripple migration (superposed on the dark dunes) observed from orbit. Such morphological indications provide unprecedented details of sustained saltation on Mars. This newly found activity refutes the commonly held belief that dunes on Mars are inactive in the present-day wind regime. Such a provocative topic deserves immediate, detailed study to determine how current dune activity provides unique ground truth for today's weather patterns on Mars.

Imaging Data of Slope Streaks on Mars: Changes, Fading, Resurfacing, and Dust Transport

Thursday, August 05 2010 - 10:36 am, PDT
Dark slope streaks represent one of the most dynamic geological processes currently affecting the Martian surface.

Integrated Field Science and Exploration Activities in a Relevant Underwater Environment - Lessons for the Human Scientific Exploration of the Moon and Mars

Tuesday, March 23 2010 - 4:29 pm, PDT
The described work will provide high-fidelity science, science operations, mission operations, and technology constraints to help NASA plan for future human exploration of the Moon, Mars and other planetary bodies.

Type 2 MMAMA Proposal: Integrated Field Science and Exploration Activities in a Relevant Underwater Environment

Wednesday, September 09 2009 - 10:58 am, PDT
A multi-disciplinary underwater study to understand the factors influencing microbialite morphogenesis in Lake Pavilion, British Columbia. This study is also used to identify the human factors in exploration of a foreign environment, providing useful information for the design of human missions to the Moon and Mars.

Characterization of Martian Surface Mineralogy

Thursday, May 28 2009 - 10:39 am, PDT
Analysis of data collected from the Mars Reconnaissance Orbiter.
