Excerpt from the article. … “This is the first discovery of dust or debris at orbital altitudes around Mars,” says Bruce Jakosky, a planetary scientist at the University of Colorado at Boulder and the mission’s principal investigator. “It’s hard to understand how this stuff got here.” To read the full article go to http://www.sott.net/article/294063-Solar-system-wide-climate-change-Astronomy-in-need-of-major-re-write-as-1000-km-high-dust-clouds-and-spectacular-auroras-discovered-on-Mars
