Commander Helps Managers Plan for Future Computer Repairs



SUBMITTED BY ARTHUR N1ORC - AMSAT A/C #31468

International Space Station Commander Fyodor Yurchikhin carried out 
troubleshooting efforts on Russian segmentís central computer and 
terminal computer on Thursday. This procedure will not impact operation 
of the two channels of each computer that have been in control of 
Russian system operation since the restart on June 15.

The troubleshooting procedure is designed to help Russian mission 
managers further assess their plans for repair of the computer systems, 
including possible replacement of components with new hardware to be 
flown on the next Progress supply ship due to arrive at the station on 
July 24.

Meanwhile, the space shuttle crew that left the station Tuesday received 
an extra day in space. Bad weather forced flight controllers to wave off 
Thursday attempts. STS-117 is scheduled to land at 2:18 p.m. EDT at 
Kennedy Space Center, Fla.

STS-117 left the International Space Station bigger and more powerful 
than it was when they arrived. Atlantis also delivered a new Expedition 
15 crew member to the orbital outpost.

Expedition 15 welcomed its visitors onto the station June 10 shortly 
after Atlantis docked. A few hours later Astronaut Clayton Anderson 
replaced Suni Williams as a flight engineer on the Expedition 15 crew. 
Williams will return to Earth with STS-117, wrapping up a six-month-plus 
stay in space during which she became the new record holder for the 
longest single spaceflight by a woman.

On June 11, the STS-117 crew installed the Starboard 3 and 4 truss 
segment onto the station. The visiting astronauts conducted four 
spacewalks to activate the new truss and its solar arrays. The S3/S4 
also contains a rotary joint that will allow its arrays to track the 
sun. The S3/S4 arrays increase the stationís power generation capabilities.

The STS-117 crew also assisted with the retraction of the Port 6 (P6) 
truss array. The P6 will be relocated from atop the station to the end 
of the Port 5 truss by a future shuttle crew.

The next shuttle mission scheduled to visit the International Space 
Station is STS-118 in August.
