A docked Progress 25 cargo craft will fire its thrusters on July 21 and
23 raising the International Space Station’s orbit. The reboost provides
the proper phasing for an upcoming Progress 26 launch and docking. The
Progress firing also clears the station after the Early Ammonia Servicer
(EAS) is jettisoned during a July 23 spacewalk and provides flight day
three rendezvous opportunities when space shuttle Endeavour arrives on
mission STS-118. In advance of the reboost, the crew is testing the
command and data telemetry of the Russian computers.
The Progress 24 cargo craft will undock from the Pirs docking
compartment on Aug. 1 and burn up in the Earth’s atmosphere. 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.
The Expedition 15 crew is also preparing for the July 23 spacewalk.
Commander Fyodor Yurchikhin and Flight Engineer Clay Anderson are
familiarizing themselves with the SAFER (Simplified Aid for EVA Rescue)
jetpacks they will wear on their U.S. spacesuits.
During the spacewalk one of Anderson’s tasks is to jettison the
1,400-pound EAS. Flight Engineer Oleg Kotov is reviewing Canadarm2
procedures as he prepares to become the first cosmonaut to solely
operate the robotic arm during Monday’s spacewalk.
