Curiosity rover is expected to land on Mars in search of conditions suited to
past or present Martian life. Live coverage begins on NASA TV
at 03:30 UTC.
But this mission has been years in the making, so if you have a little catching up to do... [more inside]

In the late 1970s the UK's Anglia Television ran a respected weekly documentary series: Science Report.
But when the show was cancelled in 1977, the producers decided to channel Orson Welles in their final episode. The result was Alternative 3
. Over the course of the hour, the audience would learn that a Science Report
investigation into the UK "brain drain" had uncovered shocking revelations: man-made pollution had resulted in catastrophic climate change, the Earth would soon be rendered uninhabitable, and a secret American / Soviet joint plan was in place to establish colonies on the Moon and Mars. The show ended with footage of a US/Soviet Mars landing from May 22, 1962. After Alternative 3 aired, thousands of panicked viewers phoned the production company and demanded to know how long they had left to change planets. [more inside]

NASA May Have Discovered Flowing Water on Mars Dark, finger-like features appear and extend down some Martian slopes during late spring through summer, fade in winter, and return during the next spring. Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in the middle latitudes of Mars' southern hemisphere.

"We have water
," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA
. "We've seen evidence for this water ice before in observations by the Mars Odyssey orbiter and in disappearing chunks observed by Phoenix last month
, but this is the first time Martian water has been touched and tasted."

With all this talk of wars in distant countries, it's easy to forget that there's exciting things going on just 300 million km from your back porch. NASA has provided 90 second videos of the first 90 sols of the Spirit
[5MB .mov] and Opportunity
rovers [5MB .mov].

Life on Mars? Methane has been found in the Martian atmosphere which scientists say could be a sign of present-day life on Mars. It was detected by telescopes on Earth and has recently been confirmed by instruments onboard the European Space Agency's orbiting Mars Express craft. Methane lives for a short time in the Martian atmosphere so it must be being constantly replenished. There are two possible ways to do this. Either active volcanoes, but none have yet been found on Mars, or microbes
. The Independent has it as Methane find on Mars may be sign of life
. The second group to detect signals of methane in the Martian atmosphere is led by Michael Mumma of Nasa's Goddard Space Flight Centre in Maryland, who used powerful spectroscopic telescopes based on Earth. This team is even believed to have detected variations in the concentrations of methane, with a peak coming from the ancient Martian seabed of Meridiani Planum, which is being explored by a Nasa rover. This could indicate a subterranean source of methane which is pumping out the gas, either due to some residual geological activity or because of the presence of living organisms producing it as a waste gas. Asked whether the continual production of methane is strong evidence of a biological origin of the gas, Dr Mumma said: "I think it is, myself personally." As to how...

The Mars Gravity Biosatellite Project
is an unmatched international effort that pools top-notch technical talent from MIT, the University of Washington in Seattle, and the University of Queensland in Brisbane, Australia. The mission is nothing short of groundbreaking. The plan is to build a spacecraft capable of housing a small crew of mice, including pregnant females, which will simulate the gravity of Mars to determine its effects on mammalian development.

Did the Viking landers find life on Mars 25 years ago?
Some scientists think so. I have too much faith in planetary scientists and
the newly minted field of exobiology, to believe this is a just a ploy to
rekindle waning public interest in space exploration. I think this is
genuine 20/20 hindsight coupled with better scientific understandings of life
existing in the extreme hinterlands of possibility. . .

It's official. There was life on Mars!!!
"I am convinced that this is supporting evidence for the presence of ancient life on Mars,'' said Kathie Thomas-Keprta, an astrobiologist at the space center and the first author of a study appearing Tuesday in the Proceedings of the National Academy of Sciences.
