ice and people (Score 1)

Finding water in it's solid form taking up percentages of the soil instead of topping out at maybe one percent is amazing. This puts a whole new perspective on the whole hydrosphere of Mars. If they also find ice in the northern hemisphere it would be even better. (for humans the northern hemisphere is much more practical, less storms, lower overall elevation [radiation] more evidence of recent liquid water)
Now all we need is geothermal water, greenhouse gasses, a spacecraft that can accellerate continuously at 1 g for half the ride and brake at 1 g for the other half (creating a 40 hour journey to Mars) and the planet is ours..moahhh ha ha ha.... oops sorry about the last part.
