About Mars but let’s consider the search for life in our solar system, more generally. Ideally, we would look everywhere but this is, of course, far beyond our abilities: exploring a square meter on another planetary body is already a great challenge.
We need to figure out where life can reside in order to know Switzerland Mobile Number List where to look for it. For this, we expose microbes to extreme environments and look at how they deal with it. Then we can see where in space survivable conditions exist.
I agree, it does not give a clear-cut answer: all living forms we know have evolved on Earth, and might have become more resistant under different circumstances. But there are not that many other options and it gives us, at least, a lower boundary. That is the third objective of BIOMEX: stretching life’s limit to know where to look for it.
Can life hitch a ride on a rock?
What makes us think life on Mars will look anything like life on Earth? After all, couldn’t life on Mars have features that we cannot even imagine, as suggested by numerous writers? That’s not that likely.
The thing is: if life ever existed on Mars, it is probably related to life on Earth. Large amounts of material have been transferred from Earth to Mars, and vice-versa, by impacts from asteroids or comets. And asteroid impacts on Earth and Mars are quite common – calculated on a geological time scale, so no, there’s no need to invest in an underground bunker.
