U.S. Sen. John H. Glenn Jr. (D.-Ohio) prepares to rehearse launch readiness procedures on the mid deck of a crew trainer at the Johnson Space Center (JSC). Sharon Jones, involved in crew training, goes over a check list. When the STS-95 payload specialist lifts off aboard the Space Shuttle Discovery in October of this year and later lands in Florida, he will be seated in a temporary mid-deck chair like the one used in this training exercise.
