*Expedition 14 Crew*
HOUSTON - The Expedition 14 crew continued work this week on scientific
experiments and increased the bandwidth on the International Space
Station's computer network.
Commander Michael Lopez-Alegria and Flight Engineer Suni Williams spent
time working with experiments that may hold the key to several aspects
of long-duration space flight as NASA looks forward to missions back to
the moon and on to Mars or other destinations.
Each served as test subject and operator for the Anomalous Long Term
Effects in Astronauts' Central Nervous System experiment that examines
how cosmic radiation affects brain waves. As test subjects, they wore an
electroencephalograph cap that records readings of their brain
functions, and over that, a special helmet with Italian-designed
instruments that records the amount and types of cosmic rays passing
through the station. Since cosmic radiation is even more prevalent at
greater distances from Earth, the research could lead to countermeasures
important to the safety and productivity of future explorers.
Lopez-Alegria and Williams also worked with the Nutritional Status
Assessment experiment tracking how their bodies process nutrients in
space and how food supplies are affected by storage in that environment.
Additionally, Lopez-Alegria provided the final samples associated with
the Renal Stone Risk during Spaceflight: Assessment and Countermeasure
Validation investigation, which is looking at the space effectiveness of
a drug used on Earth to prevent kidney stones. Flight Engineer Mikhail
Tyurin worked with three Russian experiments that monitor cosmic rays
and background radiation as they relate to long-duration flights and
documented the condition of the Earth below from the unique vantage
point of the station.
The crew worked on an upgrade to the laptop computer network. The new,
integrated station computer network will be 10 times faster than the
current network, using Ethernet connectivity over a router and either
cables or wireless equipment. This will eliminate drag-through cables
from the U.S. segment into the Russian segment. The work was accelerated
because of the STS-117 launch delay.
They also continued preparations for the undocking and discarding of the
ISS Progress 23 cargo ship, which will be full of trash when it departs
Tuesday, March 27. Russian flight controllers sent commands Friday that
piped the last of the Progress 23 oxygen supplies into the station, and
vented the Progress' propellant and oxidizer lines overboard to ensure a
safe departure. The Progress is scheduled to undock at 1:11 p.m. CDT
next Tuesday.
The station traffic schedule includes next Thursday's relocation of the
Soyuz TMA-9 spacecraft from the Earth-facing port of the Zarya module to
the aft port of the Zvezda Service Module. All three crew members will
undock the Soyuz at 5:25 p.m. and redock at 5:53 p.m. This will make
room for the arrival of the Soyuz TMA-10 spacecraft carrying the
Expedition 15 crew and U.S. spaceflight participant Charles Simonyi. The
new crew is scheduled to launch from the Baikanour Cosmodrome in
Kazakhstan April 7 at 12:31 p.m. and dock with the station April 9 at
2:15 p.m.
Following a week of joint operations, Lopez-Alegria, Tyurin and Simonyi
will climb into Soyuz TMA-9 and head for home April 20. They will leave
Commander Fyodor Yurchikhin and Flight Engineer Oleg Kotov on board with
Williams to start Expedition 15.
