INTERNATIONAL SPACE STATION STATUS REPORT: SS07-14

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.
