WFIT Space Update: Maven Launch

WFIT reporter Rick Glasby, explains NASA's Maven Mission.

Features on Mars resembling dry riverbeds and the discovery of minerals that form in the presence of water indicate that Mars once had a thicker atmosphere and was warm enough for liquid water to flow on the surface. However, that thick atmosphere was somehow lost to space. Scientists suspect that over millions of years, Mars lost 99% of its atmosphere as the planet’s core cooled and its magnetic field decayed, allowing the solar wind to sweep away most of the water and volatile compounds the atmosphere once contained.
