Senator Glenn arrived at KSC on Jan. 20 to tour KSC operational areas and to view the launch of STS-89 later this week. Glenn, who made history in 1962 as the first American to orbit the Earth, completing three orbits in a five-hour flight aboard Friendship 7, will fly his second space mission aboard Space Shuttle Discovery this October. Glenn is retiring from the Senate at the end of this year and will be a payload specialist aboard STS-95
