What: Members of the news media and public are invited to watch live, online coverage of the 2012-13 NASA Student Launch Projects “launchfest,” the agency’s annual engineering and science challenge for students across the country. On Sunday, April 21, more than 600 students, representing 56 middle schools, high schools, colleges and universities in 26 states, will launch sophisticated rockets of their own design — complete with working science payloads — into the skies over North Alabama.
