Mercuries Temperature

Mercury has temperature ranges from over 400°C at noon (hot enough to melt solid zinc) to less than -150°C at night.

Tough at these temperatures you think you could find ice. Though scorched by the burning heat of the Sun any exposed frozen water would instantly be evaporated.

Recently however, a lunar probe found evidence that ice is stored in craters in the north and south poles on the Moon. This data suggests that deep craters near Mercury's poles may also contain ice deposits.
