Exploration of Planets Past, Present, and Future Habitability

Wednesday, January 07 2009 - 3:59 pm, PST
Planetary habitability is the measure of a planet's (or a satellite’s) potential to develop and sustain life. While life beyond the Earth is still uncertain, planetary missions show that conditions for habitability (i.e. water, energy, nutrients) were met in the past, and still possibly today in specific environments on Mars and on several moons of the outer solar system. Central to our investigation is the notion that habitability evolves with time. For instance, some planets could have been habitable in the past and may not be anymore; the Earth, that is not only habitable but has developed life, has seen its broad range of habitats change over geological times through climate cycles and planetary-scale catastrophes (e.g., asteroid and comet impacts) that were followed sometimes by near complete extinctions and the redistribution of habitats and dominant species. Currently, Global Warming is showing how rapidly habitats and species can disappear following climate change. Yet, humanity’s ability to explore and understand its environment can have positive consequences, which is in the case of our planet, to reduce human-induced biodiversity loss, and for other planets, to explore and engineer apparently sterile worlds (e.g., the Moon and Mars) to make them habitable and productive for future generations.

Revealing the Clays on Mars
