Tragic US astronaut Christa McAuliffe’s lost school lessons are finally going to be taught in space.

Thirty-two years after the teacher died in the Space Shuttle Challenger disaster, a pair of teachers turned astronauts on the International Space Station will pay tribute to Ms McAuliffe by carrying out her science classes.

As Nasa’s first designated teacher in space, McAuliffe was going to experiment with fluids in orbit and demonstrate Newton’s laws of motion for schoolchildren. She and six crewmates were killed after an explosion during lift-off on January 28 1986.

Astronauts Joe Acaba and Ricky Arnold will perform some of Ms McAuliffe’s lessons over the next several months.

Mr Acaba will share the news during a TV link-up with students at Ms McAuliffe’s alma mater, Framingham State University near Boston.

He will return to Earth at the end of February, while Mr Arnold heads into space up in March.
