so far, all the life forms we have found still require water to thrive. Sure, they can aestivate for a while in a dry condition, like a virus, but still need waterborne environment or host to propagate and develop. Water is the key to life.

50-100 organisms survived launch, space vacuum, 3 years of radiation exposure, deep-freeze at an average temperature of only 20 degrees above absolute zero, and no nutrient, water or energy source.

I got a feeling that life survives under conditions and places we would never imagine. We just haven't had the opportunity to discover it yet. We need to leave this little rock we live on and I suspect there will be plenty of surprises.

So far, the only place we have seriously looked for life is on a planet which has lots of liquid water.
