Search for life on Mars.
A multi-user integrated suite of instruments designed to optimize the search for evidence of life on Mars is described. The package includes: -Surface inspection and surface environment analysis to identify the potential Mars landing sites, to inspect the surface geology and mineralogy, to search for visible surficial microbial macrofossils, to study the surface radiation budget and surface oxi...
متن کاملMineralogical biosignatures and the search for life on Mars.
If life ever existed, or still exists, on Mars, its record is likely to be found in minerals formed by, or in association with, microorganisms. An important concept regarding interpretation of the mineralogical record for evidence of life is that, broadly defined, life perturbs disequilibria that arise due to kinetic barriers and can impart unexpected structure to an abiotic system. Many featur...
متن کاملMorphological biosignatures and the search for life on Mars.
This report provides a rationale for the advances in instrumentation and understanding needed to assess claims of ancient and extraterrestrial life made on the basis of morphological biosignatures. Morphological biosignatures consist of bona fide microbial fossils as well as microbially influenced sedimentary structures. To be recognized as evidence of life, microbial fossils must contain chemi...
متن کاملStudies in the search for life on Mars.
The ability of living organisms to survive extraterrestrial conditions has implications for the origins of life in the solar system. We have therefore studied the survival of viruses, bacteria, yeast, and fungi under simulated Martian conditions. The environment on Mars was simulated by low temperature, proton irradiation, ultraviolet irradiation, and simulated Martian atmosphere (CO2 95.46%,...
متن کاملLife in the Atacama: Science and Technology Pathways to the Robotic Search for Life on Mars
Introduction: Whether life ever existed on Mars or survived profound climate changes is unknown. However, all recent missions have returned evidence that thin films of liquid water or ground ice are present under current conditions [1]. Their presence supports the hypothesis that the martian subsurface could have provided a suitable refuge to life as surface conditions became hostile. Life migh...
