Did you know...
... that today is Oldest Human in Space Day? Nearly four decades after he became the first American to orbit the Earth,
Senator John Hershel Glenn, Jr., was launched into space again
as a payload specialist aboard the space shuttle Discovery. 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.
