    Study Notes

    • NASA has evidence of flowing water on Mars, which appears as dark, narrow streaks on the surface of the planet.
    • The streaks appear during the warmer months and fade the rest of the year.
    • The streaks consist of wet soil and are at least 300 feet long.
    • The chemical signature of salt compounds combined with water was detected.
    • The salt compounds prevent water from freezing at extremely low temperatures.
    • The 2015 finding could have major implications for the possibility of microscopic life forms on Mars.
    • The only way to determine whether there's life on Mars is to collect rocks and soil from the planet for analysis on Earth.
    • Liquid water could potentially be used for drinking and for creating oxygen and rocket fuel.
    • The source of the water remains a mystery, but it could be melting ice, an underground aquifer, water vapor from the thin Martian atmosphere, or some combination of these.
    • Scientists will continue to study the Red Planet to answer questions about its potential for life and the origin of liquid water.
