This Is Why Mars Is Red And Dead While Earth Is Blue And Alive

This Is Why Mars Is Red And Dead While Earth Is Blue And Alive

“Both Mars and Earth had early atmospheres that were heavy, massive, and extraordinarily rich in CO2. While Earth’s carbon dioxide got absorbed into the oceans and locked up into carbonate rocks, Mars was unable to do the same, as its oceans were too acidified. The presence of sulfur dioxide led to Martian oceans that were rich in sulfuric acid. This led to geology of Mars we’ve discovered with rovers and landers, and pointed to a different cause — the solar wind — as the culprit in the mystery of the missing Martian atmosphere.

Thanks to NASA’s MAVEN mission, we’ve confirmed that this story is, in fact, the way it happened. Some four billion years ago, the core of Mars became inactive, its magnetic field disappeared, and the solar wind stripped the atmosphere away. With our magnetic field intact, our planet will remain blue and alive for the foreseeable future. But for a smaller world like Mars, its time ran out long ago. At last, we finally know why.”

For most of the 20th century, we knew that Earth had a carbon dioxide-rich past for its atmosphere, but that those atmospheric molecules were deposited into the ocean and precipitated or fossilized out as carbonate rocks like limestone and dolomite. We assumed that Mars, which once had a thick atmosphere and a water-rich surface, lost its atmosphere the same way. But landers and rovers changed all of that, discovering very little in the way of carbonate rocks, meaning that there must have been a different process at play to strip the Martian atmosphere away.

It wasn’t until NASA’s MAVEN mission that we knew for sure! Come learn why Mars is red and dead while Earth is blue and alive today.

My wife screamed "you haven't listened to a single word I've said, have you?!"

What a weird way to start a conversation..

BMW’s Self Driving Motorcycle

BMW developed a self-driving version of its R1200GS, a motorcycle that it spent more than two years developing. The motorcycle, sans rider, can start, accelerate, lean into turns and stop all on its own. The company explained that it created the self-driving motorcycle not for consumers but to learn more about how it can implement new safety features.

Stefan Hans, a BMW safety engineer says “The prototype helps us to expand our knowledge about the vehicle’s dynamics so that we can classify the rider’s behavior and determine if a future situation will become dangerous or not, If so, we can inform, warn or intervene directly.” The bike will be used to develop new safety systems aimed at supporting inattentive drivers.
