Space Colonization: The Quiet Revolution - Space.com   The prognosis for space colonization is good, said Edward McCullough, principal scientist for The Boeing Company in Huntington Beach, California. He pointed to numbers of technologies that are on exponential growth curves - that is, showing signs of increasing rapid growth. McCullough estimates that a nominal size of a settlement on Mars would support 1,000 people, with a larger colony housing 10,000 individuals.    
Mars may have a frozen sea  - Nature  Left:  These plate-like features on Mars look strikingly similar to Antarctic pack ice. Click here to see the comparison, and more pictures.  "I was expecting glaciologists to be sceptical of our interpretation," says team member John Murray of the Open University in Milton Keynes, UK. "But when I showed the pictures to an expert on sea ice, he was utterly convinced." The researchers think that the camera has snapped a sea that froze about 5 million years ago, and was then covered by volcanic dust. "Five million years might sound like a long time," Murray says, "but in geological terms it is virtually yesterday. This suggests that pockets of liquid water have existed throughout Mars's geological history." Murray says that the area is likely to be a priority for future studies of Mars, because if there is a deep layer of liquid water below the Cerberus Fossae, life could still exist in it. 

NASA Astrobiologist Identifies 'Extreme' New Life Form - SpaceDaily  Left:  NASA astrobiologist Dr. Richard Hoover takes ice samples from the permafrost deep inside the U.S. Army's Cold Regions Research and Engineering Laboratory near Fox, Alaska. The samples, dating back some 32,000 years, contained living organisms - a previously unrecorded "extremophile" bacterial species identified by Hoover and his colleagues. Their findings were published in January 2005. NASA studies extremophiles - organisms that live and thrive in conditions inhospitable to most life on Earth - to gain insight into the possibilities for life across the cosmos.
