It's the moment at which Grace and Ed Corrigan, and their daughter Betsy, realized something was tragically wrong with the space shuttle flight they were in Florida to watch.

Grace and Ed's daughter, New Hampshire teacher Christa McAuliffe, was on board the space shuttle Challenger.

Grace was 94 when she died last Thursday, the Boston Globe says.

“Grace was basically carrying on what Christa would have done herself, had she survived that flight,” said Mary E. Liscombe, director emerita of what is now the Christa Corrigan McAuliffe Center for Integrated Science Learning at Framingham State University in Massachusetts. “She would always talk about Christa’s devotion to teaching and to the children."

After her daughter's death, Mrs. Corrigan said she took stock of her own life.

“Maybe that involves working with schools or teacher organizations or the Girl Scouts,” Mrs. Corrigan said in 1993, after her husband's death. “If I weren’t doing something I felt Christa approved of, I’d feel guilty.”

“The important lesson we can all learn from Christa is to do what you want to do and do it as well as you can. I could have done without the losses in my life, I guess. But everyone suffers some loss along the way. You cannot escape it. Who promised us a rose garden?”
