<p class="MsoNormal"><span style="font-size:13.0pt;font-family:"Georgia",serif">NASA’s MAVEN (<span class="glossarylink">Mars</span> Atmosphere and Volatile EvolutioN) spacecraft has discovered “layers” and “rifts” in the electrically charged part of the upper
atmosphere (the ionosphere) of Mars. The phenomenon is very common at Earth and causes unpredictable disruptions to radio communications. However, we do not fully understand them because they form at altitudes that are very difficult to explore at Earth. The
unexpected discovery by MAVEN shows that Mars is a unique laboratory to explore and better understand this highly disruptive phenomenon.<o:p></o:p></span></p>
