*Station Reboost Sets Stage for Upcoming Events*

Expedition 15 spacewalk


The Expedition 15 crew had a light-duty day Tuesday following Monday's 
successful station reboost and a 7-hour, 41-minute spacewalk.

During Monday's spacewalk, Flight Engineer Clay Anderson jettisoned a 
1,400 pound, refrigerator-size ammonia reservoir known as the Early 
Ammonia Servicer (EAS) by pushing it opposite of the station's direction 
of travel.

Anderson and Commander Fyodor Yurchikhin also installed a television 
camera support or stanchion, reconfigured a power supply for an antenna 
assembly, and performed several get-ahead tasks.

The docked ISS Progress 25 cargo craft fired its thrusters Monday for 
about 21½ minutes, raising the International Space Station’s orbit. This 
reboost, along with a reboost performed Friday, provides the proper 
phasing for the upcoming Progress 26 launch and docking. The two 
reboosts cleared the station from the orbit of the jettisoned EAS and 
provides flight day three rendezvous opportunities when space shuttle 
Endeavour arrives on mission STS-118.

The Progress 24 cargo craft will undock from the Pirs docking 
compartment on Aug. 1, burning up in the Earth’s atmosphere as it 
deorbits. Progress 26 is scheduled for launch on Aug. 2 and will reach 
the station on Aug. 5. Two days later on Aug. 7, space shuttle Endeavour 
is targeted for launch with a station rendezvous and docking planned for 
Aug. 9.
