John Batchelor and I welcomed back Dr. David Brain who is part of the NASA MAVEN team to discuss the recent findings regarding the solar wind as causing the loss of the Martian atmosphere over billions of years. Dr. Brain discussed the findings for the Martian upper atmosphere, he explained the solar wind, the channel which most of the atmosphere seemed to use to disappear, plus he talked about the various stages and ages of the geologic history of Mars. We talked about the conditions needed for surface water, the early Martian history and its cooling which would cause it to lose its magnetic field in the first place. John asked several questions comparing the early history of Mars with Earth, especially regarding magnetic fields, the magnetosphere and shielding from the solar wind. I asked Dr. Brain to explain the solar wind so we would all know what the solar wind is and how it fluctuates. This is an information packed 11-12 minutes, don’t miss it.
