1
00:00:06,500 --> 00:00:11,180
A big idea is coming to life.

2
00:00:11,180 --> 00:00:16,400
It’s the PACE Ocean Color instrument...OCI...

3
00:00:16,400 --> 00:00:24,000
…designed to measure intensity of light

4
00:00:24,000 --> 00:00:18,000


5
00:00:18,000 --> 00:00:20,400
…across many bands of the 

6
00:00:20,400 --> 00:00:24,800
electromagnetic spectrum.

7
00:00:24,800 --> 00:00:28,690
OCI is a one-of-a-kind instrument

8
00:00:28,690 --> 00:00:31,030
and NASA engineers are building it now.

9
00:00:31,030 --> 00:00:33,460
The most advanced ocean color instrument ever, 

10
00:00:33,460 --> 00:00:37,000
OCI will collect data to to address essential scientific

11
00:00:37,000 --> 00:00:41,000
questions about our oceans and atmosphere.

12
00:00:41,000 --> 00:00:44,200
This is the engineering model to test the system 

13
00:00:44,200 --> 00:00:49,430
that will ultimately be built to fly on PACE.

14
00:00:49,430 --> 00:00:49,500
Engineers will test the model

15
00:00:49,500 --> 00:00:53,300
and those tests will inform the construction

16
00:00:53,300 --> 00:00:59,000
of flight hardware.

17
00:00:59,000 --> 00:01:03,000
Science needs new tools

18
00:01:03,000 --> 00:01:03,800
to answer big questions.

19
00:01:03,800 --> 00:01:04,000
When it launches

20
00:01:04,000 --> 00:01:08,000
The PACE mission will be an Earth science leader

21
00:01:08,000 --> 00:01:11,000
and OCI will provide first-of-its-kind

22
00:01:11,000 --> 00:01:14,800
ocean observations as well as

23
00:01:14,800 --> 00:01:16,000
capabilities to monitor atmospheric aerosols

24
00:01:16,000 --> 00:01:20,000
and clouds, continuing essential data records

25
00:01:20,000 --> 00:01:24,096
and extending our capabilities for a new generation.
