This informative video has some more thorough background on the topic.
Here is a bit more information on the space device that has taken the pics and collected the data. Without this detailed information NASAS would not have been able to model things out in such fashion:
NASA’s MAVEN spacecraft is flying high above the Red Planet with a battery of sensors. While previous Mars orbiters have peered down at the planet’s surface, MAVEN is spending part of its time gazing at the stars, looking for subtle changes in their color as they dip through the limb of Mars and set below the horizon. Such stellar occultations reveal what the atmosphere is made of, and how its composition varies with altitude. MAVEN’s observations are providing the most detailed picture of the Mars upper atmosphere to date, helping scientists understand how Mars turned from a warm and wet planet in its youth, into the forbidding desert that we see today.
And lastly, here is a discussion by Elon Musk the SpaceX founder on colonizing Mars. Did you ever think you would hear something like this?
Elon Musk talk about the future of private space exploration, including his long-term goal for SpaceX to “develop the technology necessary to transport large numbers of people and cargo to Mars, ultimately with the goal of establishing a self-sustaining civilization on Mars.

why didnt that happen to earth were closer to the sun
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?
Yes..old news

War with Phaeton
Yes I did.
From my understanding Mars was a planet full of life that was moon to a planet that is now the Keiper Belt?
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
Earth has a magneto sphere because of its iron core. The solar wind is deflected. It also creates the Aurora.
soung like theories my friends
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?
