STS078-429-017 (20 June-7 July 1996) --- Aboard the middeck of the Earth-orbiting space shuttle Columbia, astronaut Charles J. Brady, mission specialist and a licensed amateur radio operator or "ham", talks to students on Earth. Some of the crew members devoted some of their off-duty time to continue a long-standing Shuttle tradition of communicating with students and other hams between their shifts of assigned duty. Brady joined four other NASA astronauts and two international payload specialists for almost 17-days of research in support of the Life and Microgravity Spacelab (LMS-1) mission.
