On August 29, 2005, Hurricane Katrina made landfall along the Gulf Coast. Five years later, NASA revisits the storm with a short video that shows Katrina as captured by satellites. Before and during the hurricane's landfall, NASA provided data gathered from a series of Earth observing satellites to help predict Katrina's path and intensity. In its aftermath, NASA satellites also helped identify areas hardest hit.
