NASA's space shuttle Challenger launched from the Kennedy Space Center at Cape Canaveral on its 10th mission on Jan. 28, 1986. It exploded 73 seconds after liftoff, claiming the lives of all seven people onboard: Gregory Jarvis, Judith Resnik, Dick Scobee, Ronald McNair, Mike Smith, Ellison Onizuka and Christa McAuliffe. NASA remembered the fallen Challenger astronauts, as well as the crews of Apollo 1 and the space shuttle Columbia, in its Day of Remembrance ceremony Thursday. Many gathered at the Kennedy Space Center to remember astronauts killed in the line of duty, and other ceremonies were held at NASA centers around the country.
