Attendees of the 2010 Tom Joyner Family Reunion stand in line to receive an autograph from NASA astronaut Leland Melvin at the Gaylord Palms Convention Center in Orlando, Fla. To encourage student attendees to focus on pursuing careers in science, technology, engineering and mathematics (STEM), NASA featured some of its greatest legends and trailblazers during a panel discussion at the reunion event.

NASA's Education Office sponsored the panel discussion and educational activities as part of the agency's "Summer of Innovation" initiative and the federal "Educate to Innovate" campaign. Photo credit: NASA/Amanda Diller
