00:00:00.000 --> 00:00:00.000


00:00:00.000 --> 00:00:04.000
George Diller/STS-132 Launch Commentator: Firing chain is armed. Sound suppression water system activated.

00:00:04.000 --> 00:00:18.000
T minus 13... 12... 11... 10... nine... eight... go for main engine start... six... five... four... three... two... one... and zero...

00:00:18.000 --> 00:00:27.000
and liftoff of space shuttle Atlantis, reaching the crest of its historic achievements in space.

00:00:27.000 --> 00:00:30.000
Launch Control Center: Houston, Atlantis is in a roll.

00:00:30.000 --> 00:00:34.000
Charles Hobaugh/Capcom:  Roger, roll, Houston.

00:00:34.000 --> 00:00:38.000
Kyle Herring/STS-132 Ascent Commentator: Houston is now controlling. The roll maneuver is complete.

00:00:38.000 --> 00:00:55.000
Atlantis is in a heads-down position on course for a 51.6 degree, 136 by 36 statute mile orbit.

00:00:55.000 --> 00:01:01.000
The three main engines on Atlantis have now been throttled down to 72 percent of rated 
thrust as the orbiter

00:01:01.000 --> 00:01:14.000
prepares to pass through the area of maximum dynamic pressure on the vehicle in the lower atmosphere.

00:01:14.000 --> 00:01:21.000
Engine is now beginning to throttle back up.
Charles Hobaugh/Capcom:  Atlantis you are go at throttle up.

00:01:21.000 --> 00:01:34.000
Ken Ham/STS-132 Commander: Copy, go at throttle up.

00:01:34.000 --> 00:01:38.000
Kyle Herring/STS-132 Ascent Commentator: All three engines looking really good, back at full throttle now.

00:01:38.000 --> 00:01:44.000
At liftoff, the fully fueled shuttle, boosters and external tank weighed 4.5 million pounds.

00:01:44.000 --> 00:01:50.000
It now has burned half of that liftoff weight in propellant.

00:01:50.000 --> 00:01:54.000
One minute, 30 seconds into the flight, all three auxiliary power units that provide hydraulic power to the

00:01:54.000 --> 00:02:02.000
orbiter's systems in good shape as are the fuel cells providing electricity to all of the systems on board.

00:02:02.000 --> 00:02:14.000
Atlantis is already 19 miles in altitude, 
downrange from the Kennedy Space Center 20 miles, traveling 2,500 mph.

00:02:14.000 --> 00:02:20.000
Coming up on staging, the point of which the twin solid rocket boosters burn out and separate from the orbiter.

00:02:20.000 --> 00:02:37.000
