its second year of operation, research aboard the International
Space Station reached a new level of maturity as investigators
in a variety of science disciplines and commercial endeavors
took advantage of its ever-expanding capabilities. Two new
research facilities were added to the five existing ones,
opening possibilities in new science disciplines.
science activities on the station are orchestrated by the
Operations Center at NASA's Marshall Space Flight Center
in Huntsville, Ala. It will soon celebrate its second year
as the command post for science operations aboard the station.
Four -- December 2001 to June 2002 -- performed 27 science
experiments, while Expedition Five -- June 2002 to November
2002 -- participated in 25 science experiments, devoting
more than 1,000 hours to research. In addition, during Expedition
Five, NASA Administrator Sean O'Keefe named Expedition Five
crewmember Peggy Whitson as the first
NASA ISS Science Officer.
Expedition Six crew kicks off the third year of science
operations with NASA ISS Science Officer Don Pettit, who
will oversee 18 experiments.
2 Featured Science Disciplines
Four and Five performed scientific investigations into several
fields of study, including bioastronautics, Earth science,
physical sciences and the development of new space products.
for the first time, the long-term effects on the lungs
of doing spacewalks and living in microgravity for long
Developed and began testing two new training regimens
to lessen the time it takes to physically readapt to Earth's
gravity after spending a long time in space.
Took more than 30,000 images of the Earth.
Obtained the first high-resolution images by astronauts,
with station crews routinely acquiring images of Earth
with resolutions of 6 meters (19.7 feet).
Performed the first materials science experiments in the
Microgravity Science Glovebox and processed 16 samples
in two different furnaces.
the first human liver cells in space to develop earlier
and more reliable drug-candidate screening for patients
in need of liver and kidney treatments prior to transplants.
first station experiment to grow a common agricultural
crop plant from seed to seed.
used the microgravity environment aboard the space station
to test a technique for putting two different drugs in
a tiny, liquid-filled microballoon, as well as putting
a drug and magnetic trigger particles together in the
