It looks it might be time for us to leave earth.
NASA scientists have discovered evidence of flowing water on Mars.
We have always known that there was loads of ice there but never before had we thought of flowing water.
Now before you get carried away, we are not talking gushing fountains here. Just trickles that leave stains. These streaks happen when temperature is about -23 degrees Celcius. Salts lower the freezing point of water by the way in case you are all about the O degrees.
Why is this important?
Well it helps us by giving an indication of where life might be. Also it could mean that future human expeditions there will know where to collect water to survive.
We’re planning colonies there already.
