Evidence of Water Flowing on Mars

NASA has confirmed that there is evidence of flowing salt water on Mars. Using their Mars

Reconnaissance Orbiter, NASA found lines on Martian slopes that resemble flowing liquid and contain

hydrated salts. These lines appear to be seasonal which raises new questions on whether the water is

coming from melting ice or possibly a hidden spring. Of course this discovery has opened up

conversations around the possibility of human colonies on the red planet. But scientists have plenty of

research to conduct before we inhabit Mars.
