Barbara Morgan

Barbara Radding Morgan (born November 28, 1951) is an American teacher and a former NASA astronaut. She participated in the Teacher in Space Project as backup to Christa McAuliffe for the 1986 ill-fated STS-51-L mission of the Space Shuttle Challenger. In 1998, eight years after the Teacher in Space Project had ended, she was selected by NASA as an astronaut candidate, training as a mission specialist; astronaut Morgan flew on STS-118 in August 2007.

As such, she became the first teacher (by original career) to go into space.
