's space flight efforts. The Spacehab system provides additional pressurized workspace for experiments, cargo and crew activities. Spacehab modules have supported various Shuttle science missions along with several of the joint Shuttle-Mir missions.

For STS-95, a single-module Spacehab flew in the forward portion of Discovery's payload bay with the crew gaining access to the module through the airlock tunnel system. A variety of experiments sponsored by NASA, the Japanese Space Agency (NASDA) and the European Space Agency (ESA) focused on life sciences, microgravity sciences and advanced technology during the flight.

The Spartan 201-5 free-flyer was deployed and retrieved using the Shuttle's mechanical arm. It was designed to investigate physical conditions and processes of the hot outer layers of the Sun's atmosphere, or solar corona

Since the aging process and a space flight experience share a number of similar physiological responses, a series of experiments sponsored by NASA and the National Institute on Aging was conducted on Glenn during the STS-95 mission. The investigations gathered information which may provide a model system to help scientists interested in understanding aging. Some of these similarities include bone and muscle loss, balance disorders and sleep disturbances. Data provided from Glenn during this mission was compared to data obtained from Glenn's Friendship 7 orbital mission in 1962.
