Mars mystery solved! There’s water!
Ever since 1877 when Italian astronomer Giovanni Schiaparelli viewed Mars through a telescope and saw straight lines that he called canali, people have wondered if liquid water existed on Mars. Water flowing through the “canals” of Mars has been a popular science fiction scenario for decades. In real science, NASA researchers recently concluded that a mighty ocean once existed on Mars, and that the Martian polar caps consist primarily of frozen water ice.
Now NASA has confirmed the presence of liquid water flowing on Mars. The announcement came after scientists viewed images from NASA’s Mars Reconnaissance Orbiter (MRO) showing the strongest evidence yet that liquid water flows intermittently on present day Mars.
