NASA @ your library” is a new traveling exhibit featuring six iMacs and a plasma-screen theater, which begins a two year tour of US libraries this month. The goal of the interactive exhibit is to use the “cool factor” of space to “interest children in math and science, and to make people aware of the unique benefits of doing science in orbit.” The tour kicks off at Enoch Pratt Free Library in Baltimore, Maryland. Five exhibits will visit a total of 120 libraries, staying a month at each one.
