After months of calibration, the Lunar Reconnaissance Orbiter is providing lots of interesting new insights into the moon.  Scientists had expected that the permanently shadowed craters would hold signs of hydrogen, a indicator of ice deposits.  In a surprise, the LRO has found evidence of hydrogen both inside & outside the craters with some craters having no hydrogen at all.

The LRO also found that these permanently shadowed craters are the coldest places in the solar systems.  Readings show that temperatures in these craters never rise above 33 kelvin or minus 400 degrees Fahrenheit.  For more information, see the NASA website.
