Amazing NASA simulation of Solar Wind Striping the Martian Atmosphere

Video

The following video by NASA’s Scientific Visualization Center simulates the Martian atmosphere being striped by incoming solar wind.

Mars is a cold and barren desert today, but scientists think that in the ancient past it was warm and wet. The loss of the early Martian atmosphere may have led to this dramatic change, and one of the prime suspects is the solar wind. Unlike Earth, Mars lacks a global magnetic field to deflect the stream of charged particles continuously blowing off the Sun. Instead, the solar wind crashes into the Mars upper atmosphere and can accelerate ions into space. Now, for the first time, NASA’s MAVEN spacecraft has observed this process in action – by measuring the speed and direction of ions escaping from Mars. This data visualization compares simulations of the solar wind and Mars atmospheric escape with new measurements taken by MAVEN.

OCO-2 scientists @ JPL find patterns in Carbon Dioxide concentrations

Video

On October 29, 2015 JPL announced that scientists have found patterns in the carbon dioxide concentrations in Earth’s atmosphere. What is most interesting is tha

“…OCO-2 scientists are now beginning to study the net sources of carbon dioxide as well as their “sinks””

 

Another interesting video is this supercomputer model of CO2 levels in Earth’s atmosphere for a whole year (2006):
