摘要: In the Martian ionosphere dominant solar ionization products are O/sup +/ and CO/sub 2//sup +/. These ions rapidly converted to O/sub by ion neutral reactions resulting in as ion. As has a lower potential, each reaction results approximately 1.2 eV of energy be shared products. The kinetic given will affect temperatures. Calculations have been made heating rates temperatures which result from degradation these energetic for various production distributions conditions similar those encountered Viking 1. It is shown that thermalization can greatly increase above 200 km compared calculated using only ambient electron source. effect small horizontal magnetic fields, predicted current wind interaction models on thermal balance was also investigated. fields act restrict conductivity thus upper altitude combination themore » field provide partial agreement with 1 measurements.« less
