Low earth-orbiting satellites, such as Aqua, usually see any place on Earth no more than once a day. This daily sequence of color images from the MODIS instrument on Aqua shows the Gulf of Mexico during the period of Hurricane Katrina, from August 23 to August 30, 2005. The gaps in the MODIS imagery occur between successive orbits, about 90 minutes apart, and are filled in in this animation using high-resolution visible imagery from GOES-12.
