“…27), a stable brine should exist (Chevrier et al, 2009). At the PHX and MSL landing sites, instruments measured the temperature and relative humidity during multiple diurnal cycles (Zent et al, 2010;Gómez-Elvira et al, 2012). Other instruments on board these spacecraft have confirmed the presence of Ca(ClO 4 ) 2 in the regolith (Glavin et al, 2013;Kounaves et al, 2014b); therefore, Fig.…”

“…All data were collected during the northern summer on Mars. The data from MSL (4.59°S, 137.44°E) represent two diurnal cycles (Sols 15 and 17 of the mission, L s = 157°) as measured by REMS at the floor of Gale Crater (Gómez-Elvira et al, 2012). There were no measurements of relative humidity at either Viking landing site, but the Viking 1 (22.5°N, 50.0°W) values plotted in Fig.…”

Stability diagram for the Ca(ClO 4 ) 2 -water system overlaid with diurnal martian temperature and relative humidity data from several different missions (Savijärvi, 1995;Gómez-Elvira et al, 2012;Rivera-Valentin and Chevrier, unpublished data). Comparison with the Ca(ClO 4 ) 2 stability diagram indicates the occasional formation of a liquid phase, although the brine formed does not qualify as a Special Region due to the low temperature and water activity.…”

A New Analysis of Mars “Special Regions”: Findings of the Second MEPAG Special Regions Science Analysis Group (SR-SAG2)

et al. 2014

A committee of the Mars Exploration Program Analysis Group (MEPAG) has reviewed and updated the description of Special Regions on Mars as places where terrestrial organisms might replicate (per the COSPAR Planetary Protection Policy). This review and update was conducted by an international team (SR-SAG2) drawn from both the biological science and Mars exploration communities, focused on understanding when and where Special Regions could occur. The study applied recently available data about martian environments and about terrestrial organisms, building on a previous analysis of Mars Special Regions (2006) undertaken by a similar team. Since then, a new body of highly relevant information has been generated from the Mars Reconnaissance Orbiter (launched in 2005) and Phoenix (2007) and data from Mars Express and the twin Mars Exploration Rovers (all 2003). Results have also been gleaned from the Mars Science Laboratory (launched in 2011). In addition to Mars data, there is a considerable body of new data regarding the known environmental limits to life on Earth-including the potential for terrestrial microbial life to survive and replicate under martian environmental conditions. The SR-SAG2 analysis has included an examination of new Mars models relevant to natural environmental variation in water activity and temperature; a review and reconsideration of the current parameters used to define Special Regions; and updated maps and descriptions of the martian environments recommended for treatment as "Uncertain" or "Special" as natural features or those potentially formed by the influence of future landed spacecraft. Significant changes in our knowledge of the capabilities of terrestrial organisms and the existence of possibly habitable martian environments have led to a new appreciation of where Mars Special Regions may be identified and protected. The SR-SAG also considered the impact of Special Regions on potential future human missions to Mars, both as locations of potential resources and as places that should not be inadvertently contaminated by human activity.

Wireless Sensor Systems for Space and Extreme Environments: A Review

et al. 2014

View full text Add to dashboard Cite

Using wireless sensor network (WSN) for building new sensing and actuating applications in space and extreme environments (SEEs) can fuel a new application paradigm if it can be adopted into a new strategy. This complementary contribution from the Guest Editors carries an important message of breaking away from conventional WSN research and developments and adopting a heterogeneous agile unconventional wireless sensing (UWS) approach deployment. For this, we urge the use of lightweight WSN known as wireless sensor systems (WSS) to develop optimized solutions for SEE. This paper also discusses some critical technologies of WSS-SEE and includes three key aspects of a new approach to examine: 1) the characterizes of SEE; 2) potential applications of UWS; and 3) heterogeneously nature of the applications. A further clarification for deployment of UWS is demonstrated using a table with six groups of typical application areas from the recent publications media. Index Terms-Wireless sensing, wireless sensor systems, WSN, space, extreme environments, unconventional wireless sensing (UWS), heterogeneous sensor systems.

“…The Telltale wind indicator is a mechanical anemometer used in the Phoenix mission, Computational Fluid Dynamics analysis under Martian condition were performed to see the wakes sources [6]. Recently, CFD simulations have shown the Mars Science Laboratory Rover wind perturbation on RAMS (Rover Environmental Monitoring Station) wind measurement [7]. A study of how best to place an anemometer in planetary lander mission has been done by [8].…”

The DREAMS (Dust characterisation, Risk assessment and Environment Analyser on the Martian Surface) sensor suite is designed to investigate Martian meteorology and atmospheric electric properties at the ExoMars 2016 EDM (Entry, Descent and landing demonstrator Module) landing site. The DREAMS package will provides wind speed and direction measurement by means of MetWind hot-film anemometer and near surface temperature by means of MarsTem resistance thermometer sensor. The aim of this work is to investigate and quantify the flow distortion due to the lander and meteorological mast shape and the temperature perturbation due to the buoyant thermal plume from lander. The results of the thermal and Computational Fluid Dynamics (CFD) of the lander will be presented. Moreover, preliminary design of environmental simulation wind tunnel is presented.
