The space shuttle Atlantis launched Friday evening on a mission to the International Space Station. Atlantis lifted off from Launch Complex 39A at the Kennedy Space Center at 7:38 p.m. EDT reaching orbit about eight minutes later. Weather cooperated for the launch and there were no major technical issues during the countdown. The main purpose of the STS-117 mission is to install a new truss segment and solar panel to the station. The mission will also feature the rotation of one ISS crew member, with Clay Anderson replacing current ISS astronaut Sunita Williams.
