Life once existed on Mars, Australian scientists say
Australian scientists believe they have found evidence that life once existed on Mars.
They have found that microscopic fossils of primitive bacteria-like organisms in a Mars meteorite match characteristics of bacteria found in mud in Queensland.
The research is published today in the Journal of Microscopy.
One of the scientists, Dr Tony Taylor from the Australian Nuclear Science and Technology Organisation, says he expects his work will spark intense debate.
"The fossils that we have in the meteorite are the original material - the only difference is that you need a very high-powered electron microscope to image them, to see them and basically whenever we find these fossils here on Earth, no one ever questions they were made by bacteria," he said.
"The only difference is that it was in a meteorite from Mars."
Dr Taylor says he has found enough evidence of life on Mars to warrant a manned mission to the red planet and that more samples must now be collected from Mars for further investigation.
"We've now got enough evidence to warrant a sample retrieval mission and I believe it's going to be a matter of developing the technology to get authentic pieces of Mars back here on Earth where we can subject them to the really high-tech high resolution instruments that you can't possibly put on Mars," he said.

This should motivate a few more people about going to Mars.
