EXP 9 COMPLETES SPACEWALK



Submitted by Arthur - N1ORC - Amsat #31468

EXP 9 CREW DID A FANTASTIC JOB OF COMPLETING ALL THEIR DUTIES IN A 
SPACEWALK THAT LASTED 5 HOURS 39 MINUTES.. I HAVE TAPED A PORTION AND 
WILL PLAY IT OVER OUR LOCAL AMSAT NET ON THE WALTHAM REPEATER 146.640 ON 
THURS NITE AT 8:30  PM EDT.

* Expedition 9 Crew Restores Gyro Power*
The Expedition 9 spacewalkers successfully replaced a Remote Power 
Controller Module (RPCM) in the International Space Station's S0 Truss 
and are making their way back to the Pirs Docking Compartment.

A circuit breaker in the RPCM failed in late April and caused a loss of 
power in Control Moment Gyro (CMG) 2. There are four CMGs that control 
the ISS' orientation, located in the Z1 Truss.

This is Expedition 9's second spacewalk at the Station. The first 
occurred on June 24. The objective of today's spacewalk was carried over 
from the first spacewalk after it was cut short due to an equipment 
problem in a spacesuit. This is the 54th spacewalk conducted at the 
Station and the 29th based out of the Pirs Docking Compartment
