The hid­den, third layer in the iono­sphere

All About Space - - Mars Express -

Many ex­cit­ing dis­cov­er­ies about the Mar­tian sur­face came in the open­ing years of Mars Ex­press, but this dis­cov­ery con­firmed the pres­ence of a new, third layer in the iono­sphere of the Mar­tian at­mos­phere us­ing its Mars Ra­dio Science Ex­per­i­ment (MaRS).

Si­t­u­ated at an alti­tude be­tween 65 and 110 kilo­me­tres (37 and 68 miles), the MaRS in­stru­ment dis­cov­ered re­gions of higher den­si­ties in charged par­ti­cles such as elec­trons. The lead­ing the­ory be­hind the ori­gin of this layer is thought to be col­li­sions be­tween the iono­sphere and me­te­orites.
