STENNIS SPACE CENTER, Miss. – The visitor center at NASA's John C. Stennis Space Center, StenniSphere, has unveiled its latest permanent exhibit: Science on a Sphere, a 68-inch global presentation of planetary data of the past, present and future. StenniSphere is the third NASA visitor center to offer Science on a Sphere, a computer system that uses four projectors to show dynamic, revolving, animated views of Earth’s and other planets’ atmosphere, geography and more. Science on a Sphere was developed by NOAA about five years ago. Stennis is the 36th site to house the exhibit. (Source: NASA, 05/23/09)
