The Aqua satellite orbits the Earth every 99 minutes in a polar, sun-synchronous orbit. The MODIS instrument on Aqua observes reflected light from the Earth in 36 spectral frequencies. These observations can be processed to show many properties of the Earth's surface, from temperature and phytoplankton measurements near the surface of the ocean to fire occurrences and land cover characteristics on the land surface.
The MODIS observations start out divided into 5-minute sections called granules, and this animation shows about 4 days of MODIS granules processed to look like true-color photographs of the planet's surface.

Four days of Aqua MODIS true-color granules during the period of Hurricane Katrina, from August 27, 2005 through August 30, 2005.
