MAVEN Videos
	Ultraviolet Mars Reveals Cloud Formation - 10/17/2016 Images from MAVEN's Imaging UltraViolet Spectrograph were used to make this movie of rapid cloud formation on Mars on July 9-10, 2016. The ultraviolet colors of the planet have been rendered in false color, to show what we would see with ultraviolet-sensitive eyes. The movie uses four MAVEN images to show about 7 hours of Mars rotation during this period, and interleaves simulated views that would be seen between the four images. Mars' day is similar to Earth's, so the movie shows just over a quarter day. The left part of the planet is in morning and the right side in afternoon. Mars' prominent volcanoes, topped with white clouds, can be seen moving across the disk. Mars' tallest volcano, Olympus Mons, appears as a prominent dark region near the top of the images, with a small white cloud at the summit that grows during the day. Olympus Mons appears dark because the volcano rises up above much of the hazy atmosphere which makes the rest of the planet appear lighter. Three more volcanoes appear in a diagonal row, with their cloud cover merging to span up to a thousand miles by the end of the day. These images are particularly interesting because they show how rapidly and extensively the clouds topping the volcanoes form in the afternoon. Similar processes occur at Earth, with the flow of winds over mountains creating clouds. Afternoon cloud formation is a common occurrence in the American West, especially during the summer.

	Investigating the Martian Atmosphere - 9/18/2014 The Martian surface bears ample evidence of flowing water in its youth, from crater lakes and riverbeds to minerals that only form in water. But today Mars is cold and dry, and scientists think that the loss of Mars' water may have been caused by the loss of its early atmosphere. NASA's Mars Atmosphere and Volatile EvolutioN mission, or MAVEN, will be the first spacecraft devoted to studying the Red Planet's upper atmosphere, in an effort to understand how the Martian climate has changed over time.
