3 Scientific Breakthroughs That May Change Your Life: Water on Mars, the Missing Link and Cancer Bloodtests

Liquid Water on Mars

After much speculation about life on other planets, NASA is zeroing in on the conditions necessary for life. Findings from the Mars Reconnaissance Orbiter (MRO) seem to show that water does flow currently on Mars. The dark streaks on the MRO flow down slopes similar to mountains or ridges during hotter times, while they retreat during colder months. The flows are a liquid that scientists describe as “briny,” possibly from salt deposits from the surface of Mars. The hydrated salts appear to have chemical signatures that could be a mixture of magnesium chlorate, magnesium perchlorate and sodium perchlorate. The perchlorates are key, since they are able to stop liquids from freezing even at the extreme temperatures of Mars.
