As quoted in "I Touch the Future —" : The story of Christa McAuliffe (1985) by Robert T. Hohler, p. 155; this was on a t-shrit which she brought on her shuttle baggage, but the expression might not have originated with her.
(RESPONSE) Though the expression might not have originated by Christa, she endorsed it and repeated it as captured on a YouTube video, https://www.youtube.com/watch?v=uZfKrXp-ghM , starting at the 7:39 mark. (Christa was speaking before various media microphones, including one microphone belonging to WJYY radio, a Concord, NH, station where Christa lived.) Also, in the biography of Christa by her mother, Grace Corrigan, the expression is attributed to Christa by former student (1975), Roger Chapan, who quoted Christa as saying: “I teach; I touch the future.” (See A Journal for Christa: Christa McAuliffe, Teacher in Space by Grace George Corrigan, 1993, ISBN 0-8032-1459-6, page 162) Regardless of who originated the expression (and it may very well have been Christa), it was Christa McAuliffe who popularized it and indelibly etched it into the minds of everyone in the world with her tragic passing.
