From 1981 to 2011, the United States focused on reusable space shuttles. Many successful shuttle launches completed scientific and military space missions during this time. However, the space shuttle program was marred by two major tragedies. On January 28, 1986, the space shuttle Challenger exploded 73 seconds after liftoff. All seven people on board died, including a teacher named Christa McAuliffe. McAuliffe would have been the first civilian in space. The second tragedy occurred on February 1, 2003. The shuttle Columbia was returning from a 16-day research mission when it disintegrated while reentering Earth’s atmosphere. The seven-person crew died.
