Life on Mars?
Researchers are reexamining the data from the Mars Viking mission. Once again they are looking for signs of life, but it’s not the kind the probes were originally designed to find. Most of us have read or heard about researchers recently studying organisms in extreme environments. Any organisms that would have evolved and survived to present day on Mars would have had to adapt to a relatively extreme environment. The researchers believe that organisms on Mars may have developed a water/hydrogen peroxide solution instead of the water/salt solution that organisms on Earth developed.The original test that the Viking probe used would not have detected signs of life if the organisms were made of a water/hydrogen peroxide solution.

We may already have ‘met’ Martian organisms, according to a paper presented Sunday (Jan. 7) at the meeting of the American Astronomical Society in Seattle.
