1 00:00:00,000 --> 00:00:01,000 \h 2 00:00:02,470 --> 00:00:10,803 Mike Curie/STS-133 Launch Commentator: Go for main engine start. We have main engine start. 2 . . . 1 . . . booster ignition. 3 00:00:11,860 --> 00:00:12,180 And the final liftoff of Discovery! A tribute to the dedication, hard work and pride of 4 00:00:17,340 --> 00:00:21,606 America's space shuttle team. The shuttle has cleared the tower. 5 00:00:31,060 --> 00:00:37,060 Josh Byerly/STS-133 Ascent Commentator: Discovery now making one last reach for the stars. 6 00:00:55,710 --> 00:00:58,356 Discovery's engines are now throttling down as the orbiter passes through the area of 7 00:00:58,730 --> 00:01:03,663 maximum pressure reducing the stress on the shuttle as it goes supersonic. 8 00:01:13,780 --> 00:01:14,820 Charlie Hobaugh/STS-133 CAPCOM: Discovery, Houston, you are go at throttle up. 9 00:01:17,940 --> 00:01:20,873 Steve Lindsey/STS-133 Commander: (Inaudible) 10 00:01:23,700 --> 00:01:25,549 Josh Byerly/STS-133 Ascent Commentator: Commander Steve Lindsey acknowledging 11 00:01:25,550 --> 00:01:31,416 the call from CAPCOM Charlie Hobaugh as Discovery's three main engines throttle back up. 12 00:01:33,290 --> 00:01:40,156 Lindsey is joined on the flight deck by Pilot Eric Boe and Mission Specialist Al Drew and Nicole Stott. 13 00:01:44,060 --> 00:01:47,260 Mission Specialist Mike Barratt and Steve Bowen. 14 00:01:47,940 --> 00:01:49,830 Discovery's three main engines are burning fuel at a rate that would drain an average swimming pool in about 25 seconds. 15 00:01:54,050 --> 00:01:54,600 The engines, combined with the solid rocket boosters, produce more than 7 million pounds of thrust. 16 00:02:00,100 --> 00:02:02,723 One minute, 50 seconds into the flight, we're standing by for separation of the twin solid rocket boosters. 17 00:02:04,610 --> 00:02:12,476 Discovery now traveling 2,695 miles an hour. It's altitude 24 miles. Downrange from the Kennedy Space Center 29 miles.
