Scientists in China say they have discovered that a type of moss would survive on Mars.
Syntrichia caninervis is type of moss usually found in regions such an Antartica or the Mojave desert.
But now, scientists has been found that it can survive Mars-like-conditions including drought, high levels of radiation and extreme cold.
I have wondered why we haven't just started trying to populate/pollute Mars with some kind of giga-greenhouse dropped from space and plastic grocery bags.
