When NASA’s MAVEN mission begins its journey to the Red Planet later this year, it will be equipped with a special instrument to take the planet back in time. That instrument is the Neutral Gas and Ion Mass Spectrometer, a network of electrically charged rods that will measure the charged gas particles—or ions—making up Mars’ upper atmosphere.
Hundreds of individual lava flows are seen frozen in time on the flanks of Olympus Mons, the largest volcano in the Solar System.
An international team of researchers studying data beamed back by NASA's Mars Reconnaissance Orbiter have observed seasonal changes on far-northern sand dunes on the Red Planet caused by warming of a winter blanket of frozen carbon dioxide.
