Salt Lake City, UT – NASA calls it the "A Train." It's a group of specialized satellites orbiting the earth in formation. Two of them, Cloudsat and Calipso, will be launched Friday, April 21st, from Vandenburg Air Force Base in California. University of Utah Associate Professor Jay Mace will be there for the launch.
