"This month our expert panel take an in-depth look at Mars and the future of space travel," says the BrisScience PR, "While attempting to answer the age-old question… are we alone in the universe?"
"The possibility of life on Mars is small but not non-existent," he revealed, "The Martian atmosphere removes very little of the radiation from the sun and the temperatures are extremely low, as is the pressure. Anything alive on Mars would probably have to live below the surface.
"Unfortunately, Perchlorates in the Martian ground mean the water found on Mars is extremely salty and far too toxic for any microbial life we have seen on Earth. However, extremophiles, creatures that live in habitats of extremes (temperature, pressure, salinity etc.) keep being found that push back the limits of what we consider liveable. So maybe a Martian microbe might surprise us. We have to send more probes, and then humans, to check and make sure."
