1
00:00:08,050 --> 00:00:04,020
Intro dynamic music.

2
00:00:08,070 --> 00:00:12,080
Rob Baltrum: Ok, so we are here in the clean room at Ball Aerospace looking at the NPP spacecraft.

3
00:00:12,100 --> 00:00:16,140
What you are looking at is the Nadir deck, essentially, the instrument

4
00:00:16,160 --> 00:00:20,160
or the Earth-facing deck, where all the instruments and the Earth-facing antennas are located.

5
00:00:20,180 --> 00:00:24,180
Every orbit, we collect an orbit's worth of data for about a 101

6
00:00:24,200 --> 00:00:28,200
minutes and we fly over Svalbard, Norway. We downlink the data.

7
00:00:28,220 --> 00:00:32,200
The large instrument here you see basically at the

8
00:00:32,220 --> 00:00:36,250
front is the VIIRS instrument. That does the visible Infrared

9
00:00:36,270 --> 00:00:40,290
Radiometer Suite. VIIRS is the visible instrument collecting

10
00:00:40,310 --> 00:00:44,320
visible event data. The

11
00:00:44,340 --> 00:00:48,360
next instrument, which is currently under a bag and being purged for cleanliness

12
00:00:48,380 --> 00:00:52,380
reasons is the CrIS instrument. That's the Cross-track

13
00:00:52,400 --> 00:00:56,410
Infrared Sounder.

14
00:00:56,430 --> 00:01:00,430
Just behind that is the ATMS microwave

15
00:01:00,450 --> 00:01:04,440
sounder and those two instruments are primarily the weather data-collecting

16
00:01:04,460 --> 00:01:08,470
instruments. The instrument

17
00:01:08,490 --> 00:01:12,510
just above ATMS, that's the CERES

18
00:01:12,530 --> 00:01:16,550
instrument and basically it does Earth radiation budget

19
00:01:16,570 --> 00:01:20,580
measurements, it's a continuing data measurement.

20
00:01:20,600 --> 00:01:24,620
And then the instrument that Jim is looking at right now

21
00:01:24,640 --> 00:01:28,660
now is the OMPS sensors. Two sensors, nadir sensor

22
00:01:28,680 --> 00:01:32,680
and then a limb sensor. That does ozone measurements. So, those are the 5

23
00:01:32,700 --> 00:01:36,700
instruments that make up the instrument suite on the NPP

24
00:01:36,720 --> 00:01:40,710
mission. The other side is basically looking out at deep space,

25
00:01:40,730 --> 00:01:44,720
away from the Earth. That's where all of the spacecraft components are located.

26
00:01:44,740 --> 00:01:48,770
The batteries, the electronic boxes, our altitude sensors

27
00:01:48,790 --> 00:01:52,810
are all located on that deck. The spacecraft is just a

28
00:01:52,830 --> 00:01:56,840
big host for the science instruments

29
00:01:56,860 --> 00:02:00,870
because at the end of the day the mission is get the science data.

30
00:02:08,910 --> 00:02:04,890
Energetic music.

31
00:02:16,940 --> 00:02:12,920
Music fades out.
