Wet Chemistry Experiment at Mars (wetchem)
Introduction: NASA is developing strategies for several in-situ missions to Mars in the next few decades to explore and quantitatively assess potential habitability on Mars. Some of these missions will be designed to specifically search for biosignatures on Mars. Much of the present practice in the development of new detection technologies and instrumentation for astrobiology follows the model ...
متن کاملA cold and wet Mars
Water on Mars has been explained by invoking controversial and mutually exclusive solutions based on warming the atmosphere with greenhouse gases (the ‘‘warm and wet’’ Mars) or on local thermal energy sources acting in a global freezing climate (the ‘‘cold and dry’’ Mars). Both have critical limitations and none has been definitively accepted as a compelling explanation for the presence of liqu...
متن کاملPOLAR MARS BIOHABITABILITY ASSESSMENT OF THE WET CHEMISTRY ANALYSIS ON THE 2007 PHOENIX MARS SCOUT MISSION. S.M.M.Young,
Introduction: The 2007 Phoenix Mars Scout lander launched on 4 August 2007 and landed on 25 May 2009 at the northern polar latitude of 68.22°N, and longitude 234.25°E (areocentric) [1]. The landing site was a field of sand wedge polygonal terrain [2,3]. For 152 sols the mission made extensive atmospheric and ground measurements. Analyses included interacting with and excavating the Mars regolit...
