Spacecraft looking for life on Mars beams back jaw-dropping photos - NewsBreak

SrA Ronald Moore - Mars's atmosphere is about 1% of earths, millions of years ago, Mars inner core cooled and Mars lost it's electromagnetic shield, once that was gone the Sun's solar winds stripped Mars's atmosphere away bit by bit.

There is most likely still microbial life under the surface. During the summer, you can see signs of salt water moisture moving on the surface and there is frozen ice water in craters and at the poles. Summer temperatures can reach 70 degrees Fahrenheit with a record high temperature of 95 degrees F recorded by the Viking Rover in the shade. Estimated soil temperature was 81 degrees. Could be some life, but it would need to handle extreme swings in temperature and solar radiation. Lowest recorded temperatures on Mars was -225 degrees at the poles. Plus Mars doesn't have a large moon to keep its axis stable like Earth.

CPT David Tanner - It would not survive too close to the surface, since Mars has no electromagnetic shield, the surface is bombard with harmful radiation from the sun.

SSG (Join to see) - I agree, would need to be far enough below to avoid the radiation and temp swings. We have life here on earth that can live in ice (-128.6 F) and near boiling vents coming out of the rocks and the sea floor and air temps up to 134 F. Who knows.
