3. 2. Ion escape from Mars

   Författare :Qi Zhang; Mats Holmström; Xiao-Dong Wang; Shahab Fatemi; Hans Nilsson; David Andrews; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : When the solar wind reaches the Mars obstacle, mass loading by planetary ions slows down the solar wind and raises the bow shock. The Martian atmosphere is undergoing the a scavenging by the solar wind without the protection of a global magnetic field. Atmospheric escape is an important process for the evolution of the Martian climate. LÄS MER
