NASA Says Mars Atmosphere Was Peeled Away By Solar Wind

were you aware of THIS?

This may have BIG implications about the planet’s history.

Colonizing Mars is actually being discussed and is this a good idea?  The red planet has fascinated astronomers for centuries.  It is in a sense the most similar to ours in the solar system, and now astronomers are certain it actually has an atmosphere in the past which would make it very similar to our planet.  Here is a bit more on the statement from NASA:

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.

Solar winds blast out from the Sun at around a million miles per hour (about 1.6 million km/h), and fortunately Earth is protected from these by our magnetic field. But although Mars used to have a magnetic field, it lost it as its planet cooled down billions of years ago, and that allowed the ions in its atmosphere to effectively be blown away.

Let’s check out some cool videos with sweet pics of Mars on the next page

    From our understanding, it’s because of the following: Mars was a small planet…it’s core was small, so over time, it lost its magnetic field (from a spinning iron core). With the loss of the magnetic field, it lost its ability to protect the planet from the solar wind. The solar wind stripped off the atmosphere. No atmospheric pressure, no liquid water.

    im not as smart as you but irons onlu magnetics when coppers wrapped arount it with an electrical current how would an iron core be magnatized?

    all wrong – the Earth has a relatively large moon and as it orbits the planet it expands the Earth’s magnetosphere and that is what shields the surface of the planet from solar wind

    It’s proven that we have a magnetic field, and that that is what does indeed protect the earth. So there’s spinning iron at the core. Or, the earth is being fed through ” Birkland ” Currents of electrons ala the “Electric universe” theory.

    Has it been researched as to whether the solar wind (or solar eruption/ejection) has had any effect on the weather and or climate?
