On electron and ion components of plasma in the antisolar part of near-Martian space

Results of measurements of boundary positions and characteristics of the transition layer behind the Martian bow shock are presented. For the first time, measured characteristics of the plasma formation located behind the inner boundary of the transition layer on the antisolar part of near-Martian space are considered. The possible nature of this formation is discussed and some considerations in favor of its interpretation as the plasma sheet in the Martian magnetospheric tail are presented.
