Christa McAuliffe was set to become the first private citizen to travel to space when she boarded the Challenger space shuttle on January 28, 1986. That dream was cut tragically short when the shuttle exploded 73 seconds after liftoff, killing all seven passengers onboard. Now, 32 years later, part of McAuliffe's mission will finally be realized. As SFGate reports, two NASA astronauts are teaching her lost science lessons in space.

Before she was selected to join the Challenger crew, McAuliffe taught social studies at a Concord, New Hampshire high school. Her astronaut status was awarded as part of NASA's Teacher in Space Project, a program designed to inspire student interest in math, science, and space exploration. McAuliffe was chosen out of an applicant pool of more thanĀ 11,000.

Once in orbit, McAuliffe had planned to conduct live and taped lessons in microgravity for her students and the world to see. Though that never happened, she left behind enough notes and practice videos for astronauts to carry through with her legacy 32 years later. On Friday, January 19, astronaut Joe Acaba announced that he and his colleague Ricky Arnold will be sharing her lessons from the International Space Station over the upcoming months. The news was shared during a TV linkup with students at Framingham State University where McAuliffe studied.

McAuliffe's lost lesson plan includes experiments with Newton's laws of motion, bubbles, chromatography, and liquids in space, all of which will be recorded by Acaba and Arnold and shared online through the Challenger Center, a nonprofit promoting space science education.

It will be the first time students will get to see the lessons performed in space, but it won't be the only footage of the lessons available on the internet. Before the doomed Challenger flight, McAuliffe was able to practice her experiments in NASA's famous Vomit Comet. You can watch one of her demonstrations below.
