■ Thirty-two years after Challenger, two astronauts will carry out Christa McAuliffe’s classes in space.

CAPE CANAVERAL, Fla. — Christa McAuliffe’s lost lessons are finally getting taught in space.

Thirty-two years after the Challenger disaster, two teachers turned astronauts will pay tribute to McAuliffe by carrying out her science classes on the International Space Station.

As NASA’s first designated teacher in space, McAuliffe was going to experiment with fluids and demonstrate Newton’s laws of motion for schoolchildren, but she and six crewmates were killed during liftoff of space shuttle Challenger on Jan. 28, 1986.

Astronauts Joe Acaba and Ricky Arnold will perform some of McAuliffe’s lessons over the next several months. Acaba shared the news during a TV linkup Friday with students at her alma mater, Framingham State University near Boston.

“I can’t think of a better time or a better place to make this announcement,” Acaba said. He and Arnold “look forward to helping to inspire the next generation of explorers and educators.”

Lessons on effervescence, chromatography, liquids and Newton’s laws will be filmed by Acaba and Arnold, then posted online by the Challenger Center, a not-for-profit organization supporting science, technology, engineering and math education.

The center’s president, Lance Bush, said he’s thrilled “to bring Christa’s lessons to life.”

“We are honored to have the opportunity to complete Christa’s lessons and share them with students and teachers around the world,” Bush said in a statement.

On Friday, he thanked Acaba, who along with two station crewmates fielded questions from Framingham State students.

NASA’s associate administrator for education, Mike Kincaid, said the lessons are “an incredible way to honor and remember” the entire Challenger crew.
