Armstrong remained with NASA, serving as deputy associate administrator for aeronautics until 1971. After leaving NASA, he joined the faculty of the University of Cincinnati as a professor of aerospace engineering. Armstrong remained at the university for eight years. Staying active in his field, he served as the chairman of Computing Technologies for Aviation, Inc., from 1982 to 1992.
Helping out at a difficult time, Armstrong served as vice chairman of the Presidential Commission on the space shuttle Challenger accident in 1986. The commission investigated the explosion of the Challenger on January 28, 1986, which took the lives of its crew, including school teacher Christa McAuliffe.
Despite being one of the most famous astronauts in history, Armstrong has largely shied away from the public eye. He gave a rare interview to the news program 60 Minutes in 2006. He described the moon to interviewer Ed Bradley, saying “It’s a brilliant surface in that sunlight. The horizon seems quite close to you because the curvature is so much more pronounced than here on earth. It’s an interesting place to be. I recommend it.” That same year, his authorized biography came out. “First Man: The Life of Neil A. Armstrong” was written by James R. Hansen, who conducted interviews with Armstrong, his family, and his friends and associates.
Armstrong and his first wife divorced in 1994. He spent his final years with his second wife, Carol, in Indian Hill, Ohio. He died at age 82 on August 25, 2012, several weeks after undergoing heart surgery.
