INTERNATIONAL SPACE STATION
Expedition Two Science Operations
Status Report for Friday, March 30,
On board the orbiting laboratory, the Expedition Two
crew has successfully hooked up the first Space Station science rack.
The umbilical mating Thursday provides the Human Research
Facility rack and its experiments with cooling air and water, electricity,
pressurized gases and vacuum, and data and communications links. Final
activation, power-up and check-out activities are tentatively planned
for next week.
The HRF rack was carried to the station two weeks ago
by Space Shuttle Discovery and installed in the Destiny laboratory module
until it could be connected and brought to life. During the Station
program, it will house a variety of experiments for studying the physiological,
behavioral and chemical changes in human beings caused by space flight.
Aboard the rack are the Gas Analyzer System for Metabolic
Analysis Physiology – GASMAP – and the Ultrasound Imaging System. GASMAP
will be used on future expeditions to periodically assess crew aerobic
capacity by checking heart output, lung diffusing capacity, lung volume,
pulmonary function and nitrogen washout. Ultrasound will provide three-dimensional
images of the heart and other organs, muscles and blood vessels.
The Bonner Ball Neutron Detector and the Dosimetric
Mapping radiation-measuring experiments continue to collect data. Flight
Engineer One Jim Voss today performed a status check on Bonner Ball
to make sure it is functioning correctly.
Radiation is one of the most significant hazards for
humans during long-term space missions. These experiments will measure
the different types of radiation that penetrate the station and help
scientists more accurately predict the crew’s radiation exposure and
develop countermeasures to safely prolong human exposure to radiation
during space travel.
Flight Engineer Two Susan Helms today used the personal
computer in the Human Research Facility rack to fill out a questionnaire
as part of the Interactions experiment. After the mission, this experiment
will provide scientists on the ground with “snapshots” of crew interactions
during various phases of the mission.
The goal of this experiment is to identify and characterize
interpersonal and cultural factors that may impact the performance of
the crew in space. Ground controllers in Huntsville, Ala., also are
participating in the study.
Coming up next week, the crew plans to perform Crew Earth Observations,
transfer radiation data from a pair of dosimeters to the HRF personal
computer for transmission to the ground later, and do some on-board
training on operating the MACE II experiment. The hardware for the EarthKAM
experiment will also be checked out.
Editor’s Note: The Payload Operations
Center at NASA’s Marshall Space Flight Center in Huntsville, Ala., manages
all science research experiments aboard the International Space Station.
The center is also home for coordination of the mission-planning work
of a variety of international sources, all science payload deliveries
and retrieval, and payload training and payload safety programs for
the Station crew and all ground personnel.
