Researchers remotely unlock mysteries of water on Mars

A mission to Mars requires an estimated six-month voyage from Earth, but researchers at the University of Houston and the Lunar and Planetary Institute (LPI) have found a way to study its landscape without having to take ...

Mars' dust storms may produce peroxide snow

The planet-wide dust storms that periodically cloak Mars in a mantle of red may be generating a snow of corrosive chemicals, including hydrogen peroxide, that would be toxic to life, according to two new studies published ...

Radioactive Crystals Help Identify and Date Ore Deposits

Reddish-brown crystals of a radioactive mineral called monazite can act as microscopic clocks that allow geologists to date rock formations that have been altered by the action of high-temperature fluids, a process that frequently ...
