Could life survive on Mars? Yes, expert says


Researchers at McGill's department of natural resources, the National Research Council of Canada, the University of Toronto and the SETI Institute have discovered that methane-eating bacteria survive in a highly unique spring located on Axel Heiberg Island in Canada's extreme North. Dr Lyle Whyte, McGill University microbiologist explains that the Lost Hammer spring supports microbial life, that the spring is similar to possible past or present springs on Mars, and that therefore they too could support life.

The subzero water is so salty that it doesn't freeze despite the cold, and it has no consumable oxygen in it. There are, however, big bubbles of methane that come to the surface, which had provoked the researchers' curiosity as to whether the gas was being produced geologically or biologically and whether anything could survive in this extreme hypersaline subzero environment. 'We were surprised that we did not find methanogenic bacteria that produce methane at Lost Hammer,' Whyte said, 'but we did find other very unique anaerobic organisms - organisms that survive by essentially eating methane and probably breathing sulphate instead of oxygen.'

It has been very recently discovered that there is methane and frozen water on Mars. Photos taken by the Mars Orbiter show the formation of new gullies, but no one knows what is forming them. One answer is that there could be that there are springs like Lost Hammer on Mars. 'The point of the research is that it doesn't matter where the methane is coming from,' Whyte explained. 'If you have a situation where you have very cold salty water, it could potentially support a microbial community, even in that extreme harsh environment.' While Axel Heiberg is already an inhospitable place, the Lost Hammer spring is even more so. 'There are places on Mars where the temperature reaches relatively warm -10 to 0 degrees and perhaps even above 0 C,' Whyte said, 'and on Axel Heiberg it gets down to -50, easy. The Lost Hammer spring is the most extreme subzero and salty environment we've found. This site also provides a model of how a methane seep could form in a frozen world like Mars, providing a potential mechanism for the recently discovered Martian methane plumes.'

British scientists on a new mission to Mars..

London: British scientists on Friday announced the start of work onndon: British scientists on Friday announced the start of work on a new mission to Mars in 2018 that will explore the possibility of life on the planet.


Scientists at the University of Leicester today announced the start of work, in collaboration with industry, on advanced instruments for ExoMars (Exobiology on Mars).

ExoMars is the first mission to attempt to obtain samples at a depth of 1-2 metre below the surface of Mars where they are protected from radiation and oxidants thought

to exist on the surface, and both of which would destroy heavily degrade complex organic compounds.

The scientists from the university are involved in five instruments on board the ExoMars mission, including building the hardware for three of the instruments on board

the craft.


The ExoMars mission is one of the key missions under the remit of the newly formed UK Space Agency.

ExoMars is a European-led robotic mission to Mars, developed by the European Space Agency (ESA) and NASA.

It is part of ESA's Aurora programme for robotic exploration of the Solar System and its aim is to further characterise the chemical, geological and possible biological

environment on Mars in preparation for robotic missions and then human exploration.

Data from the mission will also provide invaluable input for broader studies of exobiology - the search for life on other planets.

The mission to Mars also has major Earth-bound applications with spin-offs in collaboration with industry bringing environmental benefits as well as technologies that can

be applied in the fields of health and crime detection.

Professor Mark Sims said: "ExoMars is a key mission in exploration of the planet Mars. It will attempt to gather samples from a depth 1-2 metre below the surface where

they are protected from radiation and oxidants thought to exist on the surface - both of which would destroy/heavily degrade complex organic compounds".

He said the mission gives the University, and the Space Research Centre(SRC) team in particular, "the opportunity to explore the chemistry and mineralogy of Mars as well

as look at the possibility of life on Mars in the distant past, or even today, and at the same time create world-class science".

NASA Rover Finds Clue to Mars' Past and Environment for Life

ScienceDaily (June 7, 2010) — Rocks examined by NASA's Spirit Mars Rover hold evidence of a wet, non-acidic ancient environment that may have been favorable for life. Confirming this mineral clue took four years of analysis by several scientists.
An outcrop that Spirit examined in late 2005 revealed high concentrations of carbonate, which originates in wet, near-neutral conditions, but dissolves in acid. The ancient water indicated by this find was not acidic.

NASA's rovers have found other evidence of formerly wet Martian environments. However the data for those environments indicate conditions that may have been acidic. In other cases, the conditions were definitely acidic, and therefore less favorable as habitats for life.

Laboratory tests helped confirm the carbonate identification. The findings were published June 3 by the journal Science.

"This is one of the most significant findings by the rovers," said Steve Squyres of Cornell University in Ithaca, N.Y. Squyres is principal investigator for the Mars twin rovers, Spirit and Opportunity, and a co-author of the new report. "A substantial carbonate deposit in a Mars outcrop tells us that conditions that could have been quite favorable for life were present at one time in that place. "

Spirit inspected rock outcrops, including one scientists called Comanche, along the rover's route from the top of Husband Hill to the vicinity of the Home Plate plateau which Spirit has studied since 2006. Magnesium iron carbonate makes up about one-fourth of the measured volume in Comanche. That is a tenfold higher concentration than any previously identified for carbonate in a Martian rock.

"We used detective work combining results from three spectrometers to lock this down," said Dick Morris, lead author of the report and a member of a rover science team at NASA's Johnson Space Center in Houston."The instruments gave us multiple, interlocking ways of confirming the magnesium iron carbonate, with a good handle on how much there is."

Massive carbonate deposits on Mars have been sought for years without much success. Numerous channels apparently carved by flows of liquid water on ancient Mars suggest the planet was formerly warmer, thanks to greenhouse warming from a thicker atmosphere than exists now. The ancient, dense Martian atmosphere was probably rich in carbon dioxide, because that gas makes up nearly all the modern, very thin atmosphere.

It is important to determine where most of the carbon dioxide went. Some theorize it departed to space. Others hypothesize that it left the atmosphere by the mixing of carbon dioxide with water under conditions that led to forming carbonate minerals. That possibility, plus finding small amounts of carbonate in meteorites that originated from Mars, led to expectations in the 1990s that carbonate would be abundant on Mars. However, mineral-mapping spectrometers on orbiters since then have found evidence of localized carbonate deposits in only one area, plus small amounts distributed globally in Martian dust.

Morris suspected iron-bearing carbonate at Comanche years ago from inspection of the rock with Spirit's Moessbauerpectrometer, which provides information about iron-containing minerals. Confirming evidence from other instruments emerged slowly. The instrument with the best capability for detecting carbonates, the Miniature Thermal Emission Spectrometer, had its mirror contaminated with dust earlier in 2005, during a wind event that also cleaned Spirit's solar panels.

"It was like looking through dirty glasses," said Steve Ruff of Arizona State University in Tempe, Ariz., another co-author of the report. "We could tell there was something very different about Comanche compared with other outcrops we had seen, but we couldn't tell what it was until we developed a correction method to account for the dust on the mirror."

Spirit's Alpha Particle X-ray Spectrometer instrument detected a high concentration of light elements, a group including carbon and oxygen, that helped quantify the carbonate content.

The rovers landed on Mars in January 2004 for missions originally planned to last three months. Spirit has been out of communication since March 22 and is in a low-power hibernation status during Martian winter. Opportunity is making steady progress toward a large crater, Endeavour, which is about seven miles away.
