NASA and the science education Challenger Center released a video Tuesday of astronaut-educator Ricky Arnold performing, aboard the International Space Station, one of the experiments Christa McAuliffe developed for the ill-fated space flight aboard the shuttle Challenger, before the spacecraft exploded during the launch in 1986, the Associated Press reports.
McAuliffe was a high school science teacher from Concord, New Hampshire, but she never got to teach from space, having perished just 73 seconds after liftoff on January 28, along with with her six crewmates.

The center’s June Scobee Rodgers, widow of Challenger commander Dick Scobee, thanked Mr Arnold during a TV linkup for making McAuliffe’s lessons “come to life.”
The first lesson demonstrated how a mixture separates into its individual parts. He used chromatography paper, water, food coloring and a felt pen.
