      Well you should listen to Pete. (Though I would hazard a guess that it depends quite a bit on which bit of Mars you try to eat.)

      personally, I haven’t licked Mars so I had a look on the internet and I think Pete is right. Scientists saw what looked like water flowing down crater walls on Mars in images/ time lapse videos taken by the Reconnaissance Orbiter so they checked it out. They used something called an Imaging Spectrometer to work out what this liquid was made of and it turns out it’s REALLY salty water. Scientists think they saw the water during summer time on Mars when it gets warm enough for the salty water to thaw a wee bit because Mars is normally so cold water (even very salty water) would be frozen.

      In short, I haven’t licked Mars but it’s probably salty 🙂
