NASA and the Challenger Center present Christa’s Lost Lessons. Christa McAuliffe was chosen to be the first teacher in space. Due to the tragic space shuttle Challenger disaster in 1986, she did not film the science lessons in space as planned. Educators-turned-astronauts, Joe Acaba and Ricky Arnold, spent the 2017-18 school year aboard the International Space Station for A Year of Education on Station. As a tribute to McAuliffe and her legacy, Acaba and Arnold completed her mission. The demonstrations were filmed aboard the International Space Station and corresponding lessons were developed for classrooms.

Watch the video demonstrations and teach the science lessons of the first educator chosen for the Teacher In Space program.
