NASA’s MAVEN (Mars 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.

Why can't we use hydrogen balloons to put instruments at the right levels above earth, I wonder?
Do they think the static fluctuations, including the rifts, can be attributed to the almost total lack of atmosphere, or the lack of magnetic field on MARS, or something else?
Maybe I should read the NASA release.....nope, no answers there, only a near verbatim transcript of the narration.
