Chosen to be the first teacher in space, McAuliffe and seven others were killed when the Space Shuttle Challenger broke apart just after launch on January 28, 1986.

Ricky and his NASA colleague, Astronaut Joe Acaba, were both educators before becoming astronauts. Separately, they 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 while they were in space. You can now watch the video demonstrations and teach the science lessons of the first educator chosen for the Teacher In Space program:

The lessons were completed thanks to a partnership between the Challenger Center--a 501(c)3 organization created by the families of the the Challenger crew to continue the crew's educational mission--and NASA.
