	Life on Mars - Wikipedia, the free encyclopedia
		Mars' polar ice-caps were observed as early as the mid-17th century, and they were first proven to grow and shrink alternately, in the summer and winter of each hemisphere, by William Herschel in the latter part of the 18th century.
		By the mid-19th century, astronomers knew that Mars had certain other similarities to Earth, for example that the length of a day on Mars was almost the same as a day on Earth.
		Since formaldehyde is produced in the oxidation of methane, which occurs on Mars, it is unsurprising that it is detected in the Martian atmosphere.

		Recent data from Mars Global Surveyor suggest that liquid water may exist just below the surface in rare places on the planet, and the 2001 Mars Odyssey will be mapping subsurface water reservoirs on a global scale.
		Therefore, future missions will also be on the lookout for energy sources other than sunlight, since life on the surface of mars is unlikely given the presence of "superoxides" that break down organic (carbon-based) molecules on which life is based.
		Life detection technologies under development will help us define life in non-Earth-centric terms so that we are able to detect in all the forms it might take.

	Life on Mars! It's Official!
		This year has seen the 20th anniversary of the Viking mission to Mars, a mission that failed to find evidence of living things and led subsequent meetings of "exobiologists" to the disappointing conclusion that conditions on the surface of the Red Planet were not conducive to life.
		I found life on Mars seven years ago, says Briton BRITISH scientists can claim to be the first to have found evidence of life on Mars in the wake of sensational new evidence that suggests primitive organisms may still thrive there.
		Scientists were told of the "smoking-gun evidence of life on Mars" by Dr Ian Wright, a member of the Open University team led by Prof Colin Pillinger, joint organiser of the Royal Society meeting.

		Mars is the fourth planet from the Sun, and is the outermost of the “terrestrial” (Earth-like, or rocky) planets.
		Mars appears reddish because much of it is coated with iron oxide minerals (the material that forms rust on Earth).
		Mars' smaller size — approximately one-half the diameter of Earth-- means that Mars loses its internal heat much faster than Earth does.

	New Scientist Breaking News - Life on Mars - but 'we sent it'
		There is life on Mars, a researcher has announced at a conference - unfortunately it is just spaceship-borne contamination.
		"I believe there is life on Mars, and it's unequivocally there, because we sent it," Andrew Schuerger of the University of Florida told the Lunar and Planetary Science Conference in Houston, Texas, recently.
		Schuerger says that of all the space probes sent to Mars, only the two Viking craft in 1976 were adequately heat sterilised.

	Life on Mars: Possible Evidence
		On August 6, 1996, Nasa announced the discovery of evidence for the existence of fossil life on Mars.
		This life is thought to have existed there billions of years ago (the carbonates are estimated at an age of 3.6 billion years), and consist of simple micro-organisms similar to terrestrial bacteria.
		Mars Global Surveyor confirmed this evidence from Mars orbit by photographing various landforms indicating former existence of huge quantities of water on Mars in late 1997 and early 1998.

	Life on Mars? (Site not responding. Last check: 2007-09-17)
		The case for ancient life on Mars looks better than ever after scientists announced that they had discovered magnetic crystals inside a Martian meteorite -- crystals that, here on Earth, are produced only by microscopic life forms.
		The scientists believe that these crystals traveled from Mars in the meteorite, rather than being produced on Earth by bacteria that contaminated the meteorite after it arrived in Antarctica.
		But several facts support a Martian origin, including the deep embedding of the crystals in the carbonate material of the meteorite and the preference of the magnetite-producing bacteria for low-oxygen environments, making it unlikely that such bacteria would live where the meteorite was found.

	Life on Mars?
		The possibility of life on Mars has fascinated many, including the wealthy American astronomer Percival Lowell, who erroneously thought he had discovered hundreds of canals by 1908.
		One of Australia’s most ardent atheistic sceptics proclaimed ‘Mars life’ as a fact, and, without the caution one would expect from a scientist, used it as an excuse to launch another tirade against scientists who believe the universe and life were created.
		These dubious claims about ‘life’ in a rock are a smoke-screen, hiding the fact that true life is only found in the Rock (Isaiah 44:8), and that the only way to eternal life is through the chief Cornerstone, Jesus Christ (Ephesians 2:20, cf.

	Life on Mars
		Speculations on possible life on Mars (and other planets) go back to the first days when the nature of planets as Earth-like bodies was recognized.
		However, in 1997, Viking Life experimentator Gilbert V. Levin claimed that his experiments may have detected evidence for active microbial life on Mars.
		On August 6, 1996, scientist of Nasa and Stanford University announced the discovery of possible evidence for the existence of fossil life on Mars, found in meteorites of probable Martian origin, recovered in Antarctica.

	Apologetics Press - Life on Mars?
		The authors speculate that the bacteria grew in calcium-rich waters that had penetrated the cracks of the rock, and were preserved as the fluid hardened into carbonate.
		Ham, and others, also point out that if there ever was life (or at least, the remains of life) on Mars, then perhaps it was carried there by the solar wind from Earth’s outer atmosphere.
		But this is not the case, and there is no reason to think that life on Mars will solve this most intractable problem of materialistic evolution.

	Online NewsHour: Life on Mars? -- August 7, 1996
		KWAME HOLMAN: The possibility that life once existed on Mars has been substantially bolstered by the discovery of organic compounds in a meteorite that plunged from Mars to Earth 13,000 years ago.
		The scientists estimate a huge asteroid collided with Mars about 15 million years ago and blasted rock from Mars into space, where it wandered until it fell onto an ice field in Antarctica some 13, 000 years ago.
		KWAME HOLMAN: Life on Mars has been considered a possibility ever since it was learned water once existed on the planet’s surface, but landings by Viking spacecraft during the 1970's revealed no sign of life.
