Televised News Briefing: Dynamic Mars Over Time

Live Ustream Webcast: Tuesday, Dec. 10, 11:30 a.m. PST

There has been a continual spacecraft presence at Mars since 1997. The longevity of spacecraft missions examining the Red Planet has enabled detection and examination of changes on multiple time scales. Active processes include planet-encircling dust storms about every three to four Mars years, evolution of the polar caps, fresh impacts, migrating sand, and a suite of processes on slopes, some of which may involve liquid water. The distribution of shallow ice is much better known, with implications for recent climate change. The longer the observations continue, the deeper the understanding grows about active processes on Mars.
