Mission Objectives:
Click here for Additional Info on STS-95
The primary objectives include conducting a variety of science experiments
in the pressurized SPACEHAB module, the deployment and retrieval of the
Spartan free-flyer payload, and operations with the HST Orbiting Systems
Test (HOST) and the International Extreme Ultraviolet Hitchhiker (IEH)
payloads being carried in the payload bay.
The SPACEHAB module being flown on STS-95 is provided by SPACEHAB Inc. a
private company which provide single or double module Spacehabs to support
NASA'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 will fly 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) will focus
on life sciences, microgravity sciences and advanced technology during the
flight.
The Spartan 201 free-flyer that will be deployed and retrieved using the
Shuttle's mechanical arm and is designed to investigate physical conditions
and processes of the hot outer layers of the Sun's atmosphere, or solar
corona. While deployed from the Shuttle, Spartan will gather measurements of
the solar corona and solar wind. Information collected during this mission
will lead to a much better understanding of the solar winds that directly
influence orbiting satellites and weather conditions on Earth which in turn
impact television and phone communications. This is a reflight of the
Spartan payload flown on Mission STS-87 in November 1997 which developed
problems shortly after being deployed from the Shuttle.
The Hubble Space Telescope Orbiting Systems Test (HOST) platform is carrying
experiments to validate components planned for installation during the third
Hubble Space Telescope servicing mission and to evaluate new technologies in
an earth orbiting environment. There are four experiments on the HOST
platform. The NICMOS Cooling System will allow zero-g verification of a
Reverse Turbo Brayton Cycle Cooler which should allow longer life operation
than the current dewar system. (2) The HST 486 Computer will allow the
identification of any radiation susceptible parts in the DF-224 replacement
and demonstrate hardware and software responses to Single Event Upsets
(SEU's). (3) Solid State Recorder will compare on-orbit operation of the
flight spare solid state recorder with the current HST unit. (4) Fiber Optic
Line Test will use the same 4 kbps data stream that is sent to the orbiter's
Payload Data Interrogator (PDI) and will be routed to a laptop computer for
post-flight comparison.
The International Extreme Ultraviolet Hitchhiker (IEH) payload involves a
half dozen different experiments mounted on a support structure being
carried in Discovery's payload bay. The six experiments that make up the IEH
payload are (1) Solar Extreme Ultraviolet Hitchhiker (SEH) payload that will
obtain EUV and FUV fluxes that are required when studying the Earth's upper
atmosphere; (2) Ultraviolet Spectrograph Telescope for Astronomical Research
(UVSTAR) payload designed to measures EUV fluxes which can be used to form
images of extended plasma sources (ex. Jupiter, hot stars, etc.); (3)
STAR-LITE payload which will make observations of extended and diffused
astrophysical targets; (4) CONCAP-IV payload designed to grow thin films via
physical vapor transport; (5) Petite Amateur Navy Satellite (PANSAT) payload
which is managed by the Department of Defense Space Test Program and
involves a small deployable satellite that will store and transmit digital
communications to PANSAT ground stations; and (6) a Get-Away Special (GAS)
payload which is still TBD.
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 will be conducted during the STS-95
mission. The investigations will gather 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. Space biomedical researchers and gerontologists believe more
research in these areas could help older people live more productive and
active lives, and could reduce the number of individuals requiring long-term
medical care in their later years.
