Website Lets Users Scout the Red Planet from Home - Space.com  The website called Marsoweb had been designed to help scientists select possible landing sites for the Mars Exploration Rovers. By making the web pages more user friendly, NASA hopes that space enthusiasts will electronically survey the red planetís terrain for interesting geological features. The updated pages offer a number of computer tools. On a global map taken during the Viking mission, users can zoom in on certain spots that were imaged by the Mars Orbiter Camera with a resolution between two and 12 meters per pixel. Included with the visual images are topographical, geologic and thermal inertia maps. The thermal inertia, which quantifies how a material holds and conducts heat, gives researchers an estimate of the granularity of the surface. 
Early Humans Adapted Well To Different Climates - SpaceDaily  Early human ancestors seem to have taken different climates and vegetation types in stride as they evolved from apelike populations in Africa to a worldwide, highly diverse human species. New research supported in part by the National Science Foundation (NSF) demonstrates that hominins (early human species) in what is today northern Africa lived equally well in a relatively warm and dry climate 3.4 million years ago and in a much cooler climate with significantly more rainfall and forest growth slightly later. And the species studied, Australopithecus afarensis, adapted to these dramatic environmental changes without the benefit of an enlarged brain or stone tools, which aided later hominins in adapting to their environments. 

Rocking The Cradle Of Life - SpaceDaily  To find what many consider to be the earliest fossil evidence for life on Earth, one starting point might be to book a flight to the Pilbara region in Western Australia. On arrival in this gold-mining district, the searcher finds strange rock layers, many shaped like egg-cartons. Billions of years ago, these colonies may have formed as microbial reef deposits. Under closer examination, a few of these rocks reveal microscopic segmented shapes that hint at their complex and possibly biological origin. Given that many of these rock layers date back 3.45 billion years, their detailed study has attracted interest in the search for life on early earth.
