The Phoenix Lander shown spitting out water
on the NBC Nightly News.

After the recent find of ice crystals on Mars,
the Mars Lander Phoenix today went one step
further. Taking some of the ice crystals it
had discovered, the rover heated the ice and
then ingested the resultant water into a special
on-board analyzer.

Upon which it promptly spat the water out.

Martian water, it seems, tastes like crap.

So I guess that Mars and Earth are a lot
alike after all.
