Legal The unique mission of the Space Science Institute (SSI) is to integrate scientific research with education and public outreach. Our research program includes earth science, space physics, planetary science, and astrophysics. SSI’s National Center for Interactive Learning (NCIL) develops science and technology exhibits for museums, science centers, and libraries; develops educational websites and software interactives; provides professional development for formal and informal educators; and conducts learning research and evaluation for the education community. NCIL programs are aligned with the national education standards in science, math, and technology. http://www.nc4il.org/ http://spacescience.org/   National Science Foundation http://www.nsf.gov NSF’s Upper Atmospheric Research Section, the Geosciences Directorate, and the Informal Science Education Program provided support for the project.   NASA’s Living With A Star Program http://lws.gsfc.nasa.gov/   Site translated into Spanish by Marina LaGrave, CT.
