Chang-Diaz, Franklin (1950-...), a United States astronaut, became the first Hispanic American to travel in space. On Jan. 12, 1986, Chang-Diaz began a six-day flight on the space shuttle Columbia. The other members of the crew were astronauts Charles F. Bolden, Jr., Robert J. Cenker, Robert L. Gibson, Steven A. Hawley, George D. Nelson, and Congressman Bill Nelson of Florida. During the mission, Chang-Diaz helped release a telecommunications satellite and participated in astrophysics experiments. He has since flown in five other space missions. Few other astronauts have completed as many missions.
