This is from the NASA website (with one or two of my own additions):

Space shuttle Atlantis, its crew of six astronauts and a few insects are headed for space, ready to begin their 11-day mission to the International Space Station. The climb to orbit took about 8 1/2 minutes.
Following a smooth countdown, with no technical issues and weather that steadily improved throughout the afternoon, the shuttle lifted off on time from Launch Pad 39A at NASA's Kennedy Space Center in Florida at 2:28 p.m. EST.

I had not watched  a launch live in a while.  Glad I had an excuse to do so as the Leal butterflies-in-space specialist because it is an impressive sight.
