Australian scientists who modeled conditions on Mars to examine how much of the Red Planet was habitable said that “large regions” could sustain life. Charley Lineweaver’s team, from the Australian National University, compared models of temperature and pressure conditions on Earth with those on Mars to estimate how much of the distant planet was livable for Earth-like organisms. While just one percent of Earth’s volume — from core to upper atmosphere — was occupied by life, Lineweaver said their world-first modeling showed three percent of Mars was habitable, though most of it was...

The 520 days of isolation for the Mars500 crew will end on 4 November, when the hatch of their ‘spacecraft’ is opened for the first time since June last year. Scientists eagerly await the final samples as the crew count the hours to liberty. During the 17-month simulated Mars mission, the...

The existence of an ancient, frigid ocean on Mars that was surrounded by glaciers could explain the unusual minerals found making up the northern lowlands of the Red Planet, a new study suggests. These findings add new evidence to the idea that ancient Mars was once cold and wet, not cold and...

U.S. scientists say they’ll recreate conditions on Mars in a laboratory to see if microbial life might exist in salt droplets observed on the red planet. A NASA project led by the University of Michigan will begin three years after beads of liquid brine were first photographed on one of...
Lava, not water, said cause of Mars beds
posted by admin
A U.S. researcher says large, river-like channels seen on Mars were created not by water but by massive, fast-moving lava flows of a type we don’t see on Earth. Geoscience Professor David Leverington at Texas Tech University says what we interpret as the largest ancient riverbeds on Mars most likely were created by low-viscosity lava flows that ravaged the planet’s surface. Leverington says recent high-resolution photographs and mineralogical data support his theory for why lava is a much more likely culprit for creating the largest class of the outflow channels and canyons, some of which stretch up to 1,800 miles. The channels...

Claims of water on Mars have been made before, but a new discovery of potential liquid water on the Red Planet’s surface last week is still making waves in the science world. What differentiates the new find from previous discoveries is the fact that it’s the strongest evidence yet...
NASA Invaded Red Planet with Viking Mars Landing
posted by admin
On Mars Day every year, people celebrate the first spacecraft to successfully land on Mars — NASA’s Viking 1, which touched down on the Red Planet 35 years ago. The craft that landed July 20, 1976, the first of many visitors to Mars, had been designed to work for 90 days, but it continued gathering data for more than six years. In doing so, Viking 1 helped answer many questions about the nature of Earth’s neighbor, but it also left behind a mystery that remains tantalizingly unsolved to this very day: Is there evidence of life on Mars? Before Viking 1 arrived, scientists had no high-resolution images of the Martian surface....

NASA scientists are seeing new evidence that suggests traces of water on Mars are under a thin varnish of iron oxide, or rust, similar to conditions found on desert rocks in California’s Mojave Desert. Mars could be spotted with many more patches of carbonates than originally suspected....
