The many reports of the explorations of Mars looking for water seem to be motivated by mere curiosity. Even if water is found on Mars, the lack of a Martian magnetic field would expose any life on Mars to the ravages of radiation from space. The high-velocity sandstorms would also be adverse to any life on Mars. In light of these facts, it seems that the current explorations of Mars lack direction and purpose.
