Next: FUNDAMENTAL PHYSICS Up: SCIENTIFIC BACKGROUND Previous: Plasma Environment EXOBIOLOGY Exobiology research aims at understanding the origin of life, which, according to our current scientific knowledge, was coupled on Earth to environmental parameters like the existence of complex organic molecules, liquid water and moderate temperatures. These conditions today apparently do not exist on the other planets and moons of our Solar System. However, the occurrence of organisms in extreme ecological niches on Earth (hot springs, deep sea, hot and cold deserts) demonstrates their adaptive capability. Therefore, it cannot be completely excluded that life once developed on Mars perhaps in regions where liquid water was available. From a biological perspective the existence of liquid water, by itself motivates the question of the origin of life on Mars independent of the presence of a warm or thick atmosphere. From studies of the Earth's earliest biosphere we know that by 3.5 Ga ago, life had originated on Earth and reached a fair degree of biological sophistication. Surface activity and erosion on Earth make it difficult to trace the history of life before the 3.5 Ga timeframe. If Mars did maintain a clement environment for longer than it took for life to originate on Earth, then the question of the origin of life on Mars follows naturally. Another possibility might have been the transport of resistant life forms from Earth to Mars. The theory of panspermia requires the escape of material from Earth without impact on embedded life forms; it has been supported by first calculations and experiments with simulated outer space conditions, such as vacuum, UV-light, and cosmic ray particles, as well as in space experiments (Spacelab-1, LDEF).

Next: MARS EXPLORATION IN Up: INTERMARSNET SPECIFIC OBJECTIVES Previous: Atmosphere-Solar Wind Interactions Exobiology The scientific objectives of exobiological research on Mars include the following steps: Investigate the history of water on the planet. Locate sites where water lain sediments can be found. Search for organic materials in the soil. Search for traces of extinct life (e.g. fossils). Search for possible extant life. Investigate conditions on the surface regarding the survivability of organisms. It is likely that the INTERMARSNET Landers can contribute significantly to the first two of these objectives. In addition the geochemical investigations of the martian soil should help understand the reactive nature of these soils as shown by Viking and the resultant lack of organic materials. Jeffrey E.

Main Page Summary Context Subsurface Lithotrophic Microbial Ecosystems and Exobiology. Microorganisms living deep underground on Earth might help us understand prospects for extraterrestrial life. These warm wet subsurface oases might provide environments for extraterrestrial ecosystems. However, water and heat alone are not enough to support life. Potential extraterrestrial microorganisms would still need sources of carbon and energy. This is one reason why exobiologists are studying microbial ecosystems in extreme environments on Earth. They are searching for a model of how living organisms could obtain carbon and energy on other planets, yet resist the killing conditions found there. An example of such a model ecosystem may exist within deep subsurface aquifers of the Columbia River Basalt group in western North America. Recent investigations suggest that microorganisms in these deep groundwaters that run through volcanic rocks may form an ecosystem that persists without any dependence on the surface biosphere. Sources of energy and carbon for life.
