The International Space Station grew today when STS-117 and Expedition 
15 crew members attached the Starboard 3 and 4 truss (S3/S4) segment. 
The new truss was attached at 2:28 p.m. EDT.

The S3/S4, which is 45 feet long and weighs 35,678 pounds, was attached 
to the end of the Starboard 1 truss segment by crew members using the 
stationís robotic arm. The S3/S4 contains a new set of solar arrays that 
will increase the stationís power-generation capabilities.

The STS-117 crew will conduct three spacewalks to activate the S3/S4. 
The first spacewalk began at 2002 UTC Monday and lasted until 0217 UTC 
The new solar arrays are slated to be deployed Tuesday.

Late Sunday, NASA Astronaut Clayton Anderson joined the Expedition 15 
crew, replacing Flight Engineer Suni Williams. Anderson arrived at the 
station as a member of Space Shuttle Atlantisí crew. Atlantis docked to 
the station at 1936 UTC Sunday.

He and Williams officially changed crews when his custom-made seat liner 
was swapped out in the Soyuz spacecraft docked to the station. Williams 
is wrapping up a six-month stay aboard the station. She will return to 
Earth on Atlantis, which is slated to undock June 19. Anderson is 
scheduled to leave the station this fall.
