International Space Station Flight 2A.1
The SPACEHAB double module
is a pressurized, mixed-cargo carrier which supports various quantities,
sizes, and locations of experiment hardware. It augments the orbiter
middeck by providing a total cargo capacity of up to 4,536 kilograms
(10,000 pounds) with the ability to accommodate powered payloads.
This double module contains systems necessary to support the habitat
for the astronauts, such as ventilation, lighting and limited power.
For STS-96, the double
module carried internal and resupply cargo for station outfitting.
The flight crew had a number of duties in the SPACEHAB during the
mission, such as activation/deactivation, monitoring and in-flight
maintenance of SPACEHAB subsystems.
The SPACEHAB was activated
for the crew to begin on-orbit experiments shortly after Space Shuttle
Discovery entered orbit.
The Integrated Cargo Carrier
will carry a number of cargo items to be transferred to the station,
including Strela, an external Russian cargo crane, the SPACEHAB
Oceaneering Space System Box, a logistics items carrier, and the
ORU Transfer Device, a U.S.-built crane that will be stowed on Unity
for use during future ISS assembly missions.
The Student Tracked Atmospheric
Research Satellite for Heuristic International Networking Equipment
(STARSHINE) is a Rocky Mountain NASA Space Grant Consortium/Utah
State University sponsored ejectable satellite. The STARSHINE satellite
is a 42-centimeter (19-inch) hollow sphere covered by over 800 polished
International student volunteer
tracked this optically reflective spacecraft during morning and
evening twilight intervals for several months, calculating its orbit
from shared observations and deriving atmospheric density from drag-induced
changes in its orbit over time.
Vibration Forces Experiment
The Shuttle Vibration Forces
(SVF) experiment provided flight measurements of the vibratory forces
acting between an aerospace payload and its mounting structure.
This was accomplished using commercially available triaxial force
transducers and three Wide-band Stand-Alone Acceleration Measurement
Devices that were built by Johnson Space Center in Texas and funded by the Jet Propulsion Laboratory in California for this application.
The force transducers were incorporated into four custom brackets
that replaced the existing brackets used to attach the 1.5-meter
(five-foot) standard canister to the side wall GAS adapter beam.
The SVF payload is self-contained,
battery-powered and does not require any crew interface. The SVF
was automatically activated at liftoff, and operated for about 100
seconds. STS-96 was the second flight of the SVF experiment.
Integrated Vehicle Health Monitoring-HEDS
The Orbiter Integrated Vehicle
Health Monitoring- HEDS Technology Demonstration (IVHM HTD) demonstrated
competing modern, off-the-shelf sensing technologies in an operational
environment to make informed design decisions for future orbiter
Technologies tested included
hazardous gas detection, cryogenic line pressure sensing, structural
strain/temperature determination, thermal flow meter leak detection,
Hall Effect current sensing, accelerometers for pump vibration sensing,
VME bus architecture, flash card memory and neural networks.
NASA planned to fly two
HTDs on the same orbiter on successive flights with incorporation
of additional sensors between flights. The IVHM HTD was mounted
on a GAS Beam in the orbiter payload bay.
