SUMMARY: The space shuttle Atlantis lifted off from Cape Canaveral this morning, carrying seven astronauts and headed for the International Space Station. Liftoff occurred at 2044 GMT (4:44pm EDT), four days late because of a leaky fuel line on the shuttle's launch pad. The shuttle is expected to dock with the station on Wednesday, and astronauts will begin the first of four spacewalks to install a new truss that will serve as a backbone for the station.
