LAUNCH DATE: October 29, 1998
COST: $400 million
OVERVIEW: John Glenn will make his return to space
aboard the space shuttle Discovery as a payload specialist.
It will be his second trip into space; his first was spent
inside a 9-foot by 7-foot compartment of the Friendship 7
ship. He spent four-and-a-half hours in space and became the
first U.S. astronaut to orbit the Earth.
His mission aboard Discovery is scheduled to last 10 days.
Glenn had pushed for the assignment so he could study aging
in space. The human research on this mission will be
conducted by NASA and the National Institute on Aging, a
division of the National Institutes of Health. The research
was peer reviewed by independent scientists and includes
studies on sleep disorders, muscle atrophy, balance, and
clinical evaluations of blood and heart function.
NASA has previously flown astronauts up to 61 years old.
Glenn underwent a range of medical tests conducted by NASA
physicians and by independent consultants. They all found
him medically qualified for space flight. According to NASA
flight surgeons, Glenn's fitness level is excellent.
