Joe Knows: Solar winds dried up Mars

We finally have an understanding of how Mars transformed from a once habitable, Earth-like planet into the dry world we see today.

NASA researchers have just announced that Mars' once rich atmosphere was stripped away by solar winds in the early days of the Solar System, causing the planet to dry out.

Using the MAVEN spacecraft, which has been orbiting Mars since 2014... measurements have provided some insight into the gases that were lost from the Martian atmosphere, which include hydrogen, oxygen, and carbon dioxide – all things needed to create a liveable world.

NASA researchers believe that around 4.3 billion years ago, Mars had incredibly deep oceans that held more water than the Arctic Ocean here on Earth.

The big question is could this happen to Earth? These powerful energized Solar winds blast out from the Sun at around a million miles per hour.

Fortunately, a big magnetic field shields us from brunt of the solar winds, so we don't need to panic...unless our planet core begins to cool down...then we may have a problem!
