(countdown 10, 9 ..) 11 00:00:30,890 --> 00:00:33,890 At Cape Canaveral, the TDRS-K spacecraft sits (countdown 8, 7, 6 ...) 12 00:00:33,910 --> 00:00:36,950 atop an Atlas 5 rocket ready for launch... (countdown 5. 4. 3 ...) 13 00:00:36,970 --> 00:00:40,000 (countdown 2, 1, and) 14 00:00:40,020 --> 00:00:43,050 (countdown LIFT OFF! of the Atlas 5 rocket carrying) 15 00:00:43,070 --> 00:00:46,210 (the next generation of Tracking and Data Relay) 16 00:00:46,230 --> 00:00:49,240 (Satellites - TDRS-K) After a 4-minute burn 17 00:00:49,260 --> 00:00:52,370 the Atlas 5 main engine separates from 18 00:00:52,390 --> 00:00:55,540 the Centaur engine, and drops back to Earth. 19 00:00:55,560 --> 00:00:58,660 Shortly after separation of the main engine, 20 00:00:58,680 --> 00:01:01,680 the protective shield that covers the payload, called the 21 00:01:01,700 --> 00:01:04,760 fairing, separates to reveal the TDRS-K spacecraft. 22 00:01:04,780 --> 00:01:07,930 After boosting the spacecraft 23 00:01:07,950 --> 00:01:10,990 to geosynchronous transfer orbit, the TDRS 24 00:01:11,010 --> 00:01:14,150 spacecraft separates from the Centaur engine. 25 00:01:14,170 --> 00:01:17,200 Shortly after this separation, the two folded 26 00:01:17,220 --> 00:01:20,360 Single Access antenna reflectors are released to take 27 00:01:20,380 --> 00:01:23,370 their natural parabolic shape. 28 00:01:23,390 --> 00:01:26,470 Over the next 11 days, through a series of engine firings 29 00:01:26,490 --> 00:01:29,650 the TDRS on board rocket guides the 30 00:01:29,670 --> 00:01:32,680 spacecraft to its final location in geosynchronous orbit. 31 00:01:32,700 --> 00:01:35,730 Once arriving at this orbit, 32 00:01:35,750 --> 00:01:38,780 the spacecraft starts its deployment sequence by unfolding 33 00:01:38,800 --> 00:01:41,830 the first solar array. Next, 34 00:01:41,850 --> 00:01:44,860 the two single access antennas are deployed and locked 35 00:01:44,880 --> 00:01:48,000 into position. These antennas are designed 36 00:01:48,020 --> 00:01:51,030 to track and communicate with low-Earth orbit satellites. 37 00:01:51,050 --> 00:01:54,140 After the single access antennas are 38 00:01:54,160 --> 00:01:57,180 secured into place, the second solar array starts to 39 00:01:57,200 --> 00:02:00,230 unfold and the SGL 40 00:02:00,250 --> 00:02:03,370 and Omni antennas are deployed. 41 00:02:03,390 --> 00:02:06,440 Once TDRS-K 42 00:02:06,460 --> 00:02:09,610 completes this deployment sequence, its now ready for 43 00:02:09,630 --> 00:02:12,650 a 3 month period of testing calibration before being placed 44 00:02:12,670 --> 00:02:15,770 into service. With this addition of 45 00:02:15,790 --> 00:02:18,800 TDRS-K and the upcoming launches of 46 00:02:18,820 --> 00:02:21,910 TDRS-L and M, NASA has 47 00:02:21,930 --> 00:02:25,090 assured the future of continuous Space to Ground 48 00:02:25,110 --> 00:02:28,240 Communication. 49 00:02:28,260 --> 00:02:31,410 Beep 50 00:02:31,430 --> 00:02:34,510 Beep 51 00:02:34,530 --> 00:02:35,569 Beep
