This type of phenomenon in the environment of modern Mars could be examined as never before possible, using the combination of spacecraft now at Mars. A study published today and co-authored by CU Boulder scientists looked at observations by NASA's Mars Reconnaissance Orbiter (MRO) during the most recent Martian global dust storm. That 2007 event suggests such storms play a role in the ongoing process of gas escaping from the top of Mars' atmosphere, a process which long ago transformed wetter, warmer ancient Mars into today's arid, frozen planet....
