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.
