hi i'm nasa kennedy's jim cawley and

2
00:00:10,629 --> 00:00:04,480
this is kennedy countdown

3
00:00:12,950 --> 00:00:10,639
[Music]

4
00:00:14,789 --> 00:00:12,960
nasa's landsat 9 satellite launched on

5
00:00:17,189 --> 00:00:14,799
the united launch alliance atlas v

6
00:00:18,790 --> 00:00:17,199
rocket from space launch complex 3 at

7
00:00:20,630 --> 00:00:18,800
vandenberg space force base in

8
00:00:22,150 --> 00:00:20,640
california on monday

9
00:00:23,990 --> 00:00:22,160
built to monitor the earth's land

10
00:00:27,029 --> 00:00:24,000
surface the satellite will join its

11
00:00:28,790 --> 00:00:27,039
sister satellite landsat 8 in orbit

12
00:00:31,029 --> 00:00:28,800
working in tandem the two satellites

13
00:00:33,030 --> 00:00:31,039
will collect images spanning the entire

14
00:00:35,270 --> 00:00:33,040
planet every eight days

15
00:00:38,310 --> 00:00:35,280
landsat 9 is a joint mission between

16
00:00:40,069 --> 00:00:38,320
nasa and the u.s geological survey

17
00:00:43,830 --> 00:00:40,079
nasa's launch services program at

18
00:00:46,069 --> 00:00:43,840
kennedy space center managed the launch

19
00:00:47,670 --> 00:00:46,079
teams at kennedy performed model tests

20
00:00:49,430 --> 00:00:47,680
on the space launch system in the

21
00:00:51,110 --> 00:00:49,440
vehicle assembly building

22
00:00:52,709 --> 00:00:51,120
the tests helped determine the natural

23
00:00:55,029 --> 00:00:52,719
frequencies of the recently stacked

24
00:00:55,990 --> 00:00:55,039
rocket before launch of the artemis-1

25
00:00:58,150 --> 00:00:56,000
mission

26
00:00:59,910 --> 00:00:58,160
the data also will be used to help steer

27
00:01:02,150 --> 00:00:59,920
the rocket during flight

28
00:01:04,469 --> 00:01:02,160
to identify the sls's natural

29
00:01:05,990 --> 00:01:04,479
frequencies the team placed about 300

30
00:01:08,789 --> 00:01:06,000
sensors on the rocket and mobile

31
00:01:10,950 --> 00:01:08,799
launcher to detect record and transmit

32
00:01:13,750 --> 00:01:10,960
the information along with hydraulic

33
00:01:15,670 --> 00:01:13,760
shakers in seven locations on the rocket

34
00:01:18,310 --> 00:01:15,680
additional tests will be completed as

35
00:01:20,310 --> 00:01:18,320
nasa prepares for artemis one the first

36
00:01:22,789 --> 00:01:20,320
integrated test of the rocket and orion

37
00:01:24,710 --> 00:01:22,799
spacecraft

38
00:01:36,790 --> 00:01:24,720
