From the article:
Nearly four decades after he became the first American to orbit the Earth, Senator John Hershel Glenn, Jr., is launched into space again as a payload specialist aboard the space shuttle Discovery on October 29, 1988. At 77 years of age, Glenn was the oldest human ever to travel in space. During the nine-day mission, he served as part of a NASA study on health problems associated with aging.
