MAVEN data used for award-winning NASA Scientific Visualization Studio video

A 3-D animation created by NASA’s Scientific Visualization Studio using data from the MAVEN mission to Mars is the corporate winner of the inaugural Data Stories video contest sponsored by Science magazine for videos that tell stories about data. The video explains how the solar wind is driving particles from the upper atmosphere of Mars into space, which may have caused the planet to dry out and cool over the eons.

Created from research conducted by the entire MAVEN team, the video also won the People’s Choice award voted on by social media followers.

Scientists have long suspected the solar wind of stripping the Martian atmosphere into space, a process that may have changed Mars from an early, warm and wet environment that might have supported surface life to the cold, arid planet Mars is today.

In October 2014, MAVEN arrived at Mars and began studying its upper atmosphere. The MAVEN team has now identified the process that appears to have played a key role in the evolution of the Martian climate. Data from the orbiter have enabled researchers to determine the rate at which the Martian atmosphere currently is losing gas to space via stripping by the solar wind.
