In Situ Neutron Spectroscopy on the Martian Surface : Modeling the Hydra Instrument for Different Mission Scenarios
1. Introduction: Planetary neutron spectroscopy has proven to be highly successful in remotely detecting and measuring the abundance of water on planetary surfaces such as Mars and the Moon [1,2]. Because of the central role played by water on Mars and the need to make in situ measurements of water abundances for landed missions, neutron spectroscopy is also being investigated as a technique fo...
متن کاملAutomatically Identifying Minerals from Martian Orbit
Introduction The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) is a very high resolution near infrared spectrometer currently orbiting Mars on board the Mars Reconnaissance Orbiter (MRO). Since each mineral has a unique spectral signature, it is possible to use the measurements from this instrument to identify minerals on the surface of Mars. This project describes a method[1] to...
متن کاملDevelopment of an Ultracompact Neutron Spectrometer for Identifying Near- Surface Water on Mars
Introduction: One of the major goals of the Mars science program is to identify exact locations of near-surface water or hydrated minerals on Mars. Evidence is mounting that Mars may have contemporary near-surface groundwater activity. Though very water-poor by terrestrial igneous standards, the SNC meteorites were found to contain evaporite minerals suggestive of groundwater activity within th...
متن کاملSurvey for Life-related Species during a Planetary Surface Exploration; System Type I – Uv Stimulated Fluorescent Sensor
Introduction: The widely accepted minimum requirements for life on Earth include the presence of water and accessible sources of carbon. We assume that the same criteria must hold for putative life on past or present Mars. The evidence for CO2 and H2O at or near the Martian surface, carbon in Martian meteorites, aqueous alteration, and probable hydrothermal activity [1,2,3,4] suggest that condi...
