Organic host analogues and the search for life on Mars

摘要: Mars analogue sites represent vital tools in our continued study of the Red Planet; similar physico-chemical processes that shape a given environment on Earth allow researchers to both prepare for known Martian conditions and uncover presently unknown relationships. This review organic host analogues – mimic putatively low content examines specific locations present particular Mars-like obstacles biological processes. Low temperatures, aridity, high radiation oxidizing soils characterise modern-day Mars, while acid–saline waters would have presented their own challenges during planet's warmer wetter past. By studying each these hurdles life Earth, scientists can instruments headed identify best approaches with which look signatures. As use becomes increasingly sophisticated, will work terrestrial exhibiting multiple are tailored distinct mineralogical physical characteristics locations. Making ways enhance search signs past or Mars.
