EXP 10 STATUS - 28 MARCH 2005

*Expedition 10 Completes Successful Spacewalk 
*International Space Station crewmembers wound up a successful spacewalk 
Monday morning, finishing preparations to welcome the Automated Transfer 
Vehicle (ATV). They closed the airlock hatch at 4:55 a.m. CST (1055 GMT) 
to end their mission's second and final planned excursion outside.

Commander Leroy Chiao and Flight Engineer Salizhan Sharipov installed on 
the Zvezda Service Module the final three antennas of a six-antenna set 
for the ATV, an unpiloted European cargo carrier scheduled to make its 
first trip to the Station early next year.

They also installed a Global Positioning System (GPS) antenna for the ATV.

During this spacewalk, which began at 12:25 a.m. CST (0625 GMT), 
Sharipov and Chiao deployed a small Russian experiment called Nanosatellite.

The spacewalk, in Russian Orlan suits using the airlock of the Pirs 
Docking Compartment, lasted 4 hours, 30 minutes. Sharipov and Chiao 
completed all scheduled tasks about an hour earlier than planned.

Sharipov, designated EV1, or lead spacewalker, made his second 
spacewalk. This was the sixth spacewalk for Chiao, EV2. Both wore suits 
with red stripes. Chiao's suit had a U.S. flag on the shoulder.

After opening the hatch and assembling equipment, Sharipov and Chiao 
moved from the Pirs back to the small-diameter forward end of Zvezda. 
There they installed the three WAL antennas, space-to-space 
communications antennas for the ATV.

Installation of the antennas and their associated cabling took about 2 

Next the spacewalkers deployed the Nanosatellite, the objective of which 
is to develop small satellite control techniques, monitor satellite 
operations and develop new attitude system sensors. Sharipov deployed it 
from the ladder at Pirs at a relative velocity of about one meter per 
second, while Chiao took photos.

Next the crew moved to the large-diameter section of the Service Module 
to install the GPS antenna and its cabling. Their movements to and 
around the rear of the Service Module were coordinated carefully with 
Mission Control Moscow to avoid any possibility of contamination had it 
become necessary to use Russian thrusters there to adjust the 
orientation of the Space Station.

While near the back end of the Service Module the crew inspected a 
remotely operated Russian communications antenna and confirmed its 
location for Mission Control Moscow.

The final task was to inspect and photograph a laser reflector on the 
Service Module's aft end-cone. The reflector helps control the ATV's 
final approach to the Station, and the inspection was the last 
ATV-related activity of the spacewalk.
