STS-95: John Glenn returns to space

The first American to orbit Earth returns to orbit aboard Space Shuttle Discovery. During a ten-day mission with the SPACEHAB laboratory module installed in the cargo bay, the crew conducts medical experiments with Mercury astronaut John Glenn, comparing his results against the results of identical experiments performed with one of his crewmates, to determine the effect of weightlessness on older space travelers. At the age of 77, Glenn is the world’s oldest space traveler (and is still a sitting member of the U.S. Senate at the time of his flight). Discovery’s crew on her 25th flight is Commander Curtis Brown, Pilot Steven Lindsey, mission specialists Scott Parazynski, Stephen Robinson and Pedro Duque, and payload specialists Chiaki Mukai and John Glenn.
