00:00:02,000 --> 00:00:06,900

Narrator: NOAA is preparing for a milestone satellite launch in 2024.

00:00:06,900 --> 00:00:12,000

GOES-U will be the fourth and final satellite in NOAA’s latest generation of

00:00:12,000 --> 00:00:16,100

geostationary operational environmental satellites called the GOES-R

00:00:16,100 --> 00:00:19,766

Series - the nations’s most advanced weather-observing and

00:00:19,766 --> 00:00:22,766

environmental monitoring satellite system.

00:00:22,766 --> 00:00:28,066

GOES satellites orbit 22,236 miles above Earth’s equator,

00:00:28,066 --> 00:00:31,033

at speeds equal to its rotation.

00:00:31,033 --> 00:00:35,100

This orbit provides continuous coverage of weather systems as they

00:00:35,100 --> 00:00:38,100

develop and move across the Western Hemisphere.

00:00:38,500 --> 00:00:42,800

Narrator: GOES-U, which will be renamed GOES-19 when it reaches

00:00:42,800 --> 00:00:47,366

orbit, will replace the current GOES-16 satellite in the GOES East orbit.

00:00:47,366 --> 00:00:51,800

In this position, GOES-U will continue GOES East’s legacy of keeping

00:00:51,800 --> 00:00:56,633

watch over the contiguous United States, Central and South America, and

00:00:56,633 --> 00:00:59,633

the Atlantic Ocean.

00:00:59,833 --> 00:01:04,733

Like the three other GOES-R Series satellites already in orbit, GOES-U will

00:01:04,733 --> 00:01:08,933

provide near real-time, high-resolution imagery that will deliver critical

00:01:08,933 --> 00:01:14,000

information for weather forecasts, severe weather prediction, lightning detection,

00:01:14,000 --> 00:01:19,266

space weather and tropical cyclones spinning in the Atlantic basin.

00:01:19,266 --> 00:01:22,433

Ken Graham: It’s going to be great when, you know,

when we get into the orbit of GOES-East

00:01:22,433 --> 00:01:26,066

because you’ll be able to see, you know, we start seeing the

continental United States,

00:01:26,066 --> 00:01:29,633

but also out into the Atlantic, to the African coast because if you think

00:01:29,633 --> 00:01:33,933

about it , working at the Hurricane Center as I did, you need to be able to

00:01:33,933 --> 00:01:37,566

see some of the earliest initiation of some of these tropical systems.

00:01:38,466 --> 00:01:42,600

Narrator: And like the rest of the GOES-R Series satellites, GOES-U will

00:01:42,600 --> 00:01:46,400

include the Advanced Baseline Imager, or ABI.

00:01:46,400 --> 00:01:51,133

It is the primary instrument NOAA uses to image Earth’s weather, climate,

00:01:51,133 --> 00:01:55,166

oceans and the environment from geostationary orbit.

00:01:55,166 --> 00:01:58,833

Pam Sullivan: Yeah, ABI really rocks. Um. ABI is the primary camera on

00:01:58,833 --> 00:02:02,966

the GOES-R Series. Umm, and it has a very large focal plane.

00:02:02,966 --> 00:02:07,533

And what that does for the instrument is it can look at very wide areas of Earth.

00:02:07,533 --> 00:02:10,633

And so, because it can do that, it can scan very, very fast.

00:02:10,633 --> 00:02:15,366

What that means for the forecasters is they can look at a storm or other area

00:02:15,366 --> 00:02:18,366

of interest as often as once every 30 seconds.

00:02:18,366 --> 00:02:18,800

Music

00:02:18,800 --> 00:02:21,500

And when you can do it that fast, you know, the forecasters are

00:02:21,500 --> 00:02:24,500

really seeing that data in real time.

00:02:26,700 --> 00:02:29,300

Ken Graham: Yeah, the early detection is everything and having the

00:02:29,300 --> 00:02:32,166

instrumentation, and especially the rapid scan.

00:02:32,166 --> 00:02:34,466

To be able to have information quickly.

00:02:34,466 --> 00:02:36,966

Ah, because we have something that is such a challenge called

00:02:36,966 --> 00:02:40,733

rapid intensification where a hurricane’s just a band of clouds

00:02:40,733 --> 00:02:43,133

becomes a strong system so quickly.

00:02:43,133 --> 00:02:46,500

So, the more information and the more data we get, the quicker

00:02:46,500 --> 00:02:49,900

that we get that information, the better we can do making that forecast and

00:02:49,900 --> 00:02:52,500

getting that information into the models for a better forecast.

00:02:52,500 --> 00:02:55,966

So, having that rapid information and clarity that we’re getting in the new

00:02:55,966 --> 00:02:59,266

instrumentation, it’s just a game changer for the forecasters.

00:03:01,100 --> 00:03:04,666

Narrator: And along with the other GOES-R Series satellites, GOES-U will

00:03:04,666 --> 00:03:09,633

have the Geostationary Lightning Mapper, or G L M. The first operational

00:03:09,633 --> 00:03:13,000

lightning mapper flown in geostationary orbit.

00:03:13,333 --> 00:03:18,533

GLM identifies the location, frequency and extent of lightning over the

00:03:18,533 --> 00:03:22,966

Americas and surrounding waters, which can help forecasters understand

00:03:22,966 --> 00:03:27,233

how thunderstorms and tropical cyclones may be changing in intensity.

00:03:27,233 --> 00:03:32,266

And since its inclusion as a part of the GOES-R Series satellites, GLM has

00:03:32,266 --> 00:03:34,900

continued to provide new insights.

00:03:35,266 --> 00:03:38,666

Pam Sullivan: We found it could actually distinguish between sort of your

00:03:38,666 --> 00:03:42,500

average lightning strike and the ones that are more dangerous, the ones

00:03:42,500 --> 00:03:46,500

that are continuing current, and those are very long lightning strikes that

00:03:46,500 --> 00:03:49,200

are most likely to cause a fire.

00:03:49,333 --> 00:03:52,900

Ken Graham: Having technology in the GOES satellite, whether it’s

00:03:52,900 --> 00:03:57,166

GOES-R or GOES-U and future technology, early detection is everything.

00:03:57,166 --> 00:04:01,066

And we think about a satellite, the first thing you think of is, is a cloud.

00:04:01,066 --> 00:04:05,300

We see more than clouds. And, and the lightning detection is a key to some

00:04:05,300 --> 00:04:07,933

of our early warnings for the fire weather community.

00:04:07,933 --> 00:04:12,400

So, a lightning strike in, in a dry area in a time of that year could cause a fire,

00:04:12,400 --> 00:04:16,633

that’s an indicator to us that, that there could be a potential fire started..

00:04:16,900 --> 00:04:20,366

Narrator: Along with the suite of instruments on board NOAA’s other

00:04:20,366 --> 00:04:24,300

GOES-R Series satellites, GOES-U will carry something new when it

00:04:24,300 --> 00:04:27,300

launches. A critical space weather instrument called the

00:04:27,300 --> 00:04:31,166

Compact Coronagraph-1, or CCOR-1.

00:04:32,200 --> 00:04:36,300

CCOR-1 will be the third solar instrument on the satellite and it will image

00:04:36,300 --> 00:04:39,300

the outer layer of the Sun’s atmosphere.

00:04:39,866 --> 00:04:43,500

Elsayed Talaat: The compact coronagraph is a solar telescope that blocks

00:04:43,500 --> 00:04:46,866

the disc of the Sun, so the, the main ball of the Sun. So that we can look at

00:04:46,866 --> 00:04:50,733

the fainter outer atmosphere of the Sun called the corona.

00:04:50,733 --> 00:04:53,733

And that’s where extreme space weather events originate.

00:04:54,500 --> 00:04:58,733

Narrator: Being able to monitor the Sun’s corona helps scientists detect and

00:04:58,733 --> 00:05:03,233

characterize coronal mass ejections that can spark geomagnetic storms

00:05:03,233 --> 00:05:08,366

here on Earth. Those are the costliest type of space weather events and can

00:05:08,366 --> 00:05:13,433

widepsread damage to power grids, satellites, and communication and

00:05:13,433 --> 00:05:16,433

navigation systems.

00:05:17,266 --> 00:05:20,500

Elsayed Talaat: It’s very important for us to measure space weather effects

00:05:20,500 --> 00:05:24,133

and be able to model and provide warnings, forecasts, and alerts..uh.

00:05:24,133 --> 00:05:27,933

For space weather, uh, to protect our technological society.

00:05:27,933 --> 00:05:32,566

Basically, extreme space weather can touch all aspects of our economy

00:05:32,566 --> 00:05:35,866

and life and property here on Earth.

00:05:36,766 --> 00:05:39,100

I’m extremely excited about the compact coronagraph that we’re going to

00:05:39,100 --> 00:05:43,400

fly on the GOES-U satellite. This is a game-changer for our forecast

00:05:43,400 --> 00:05:47,000

capabilities here at NOAA in the Space Weather Prediction Center.

00:05:47,266 --> 00:05:52,600

Having that data allows us to more reliably predict when these large solar

00:05:52,600 --> 00:05:56,700

storms are going, or how they propagate towards Earth and whether or not

00:05:56,700 --> 00:06:00,700

they’re going to, uh, affect us here on Earth in a significant way.

00:06:01,600 --> 00:06:05,366

Narrator: With CCOR-1 and six other high-tech instruments on board,

00:06:05,366 --> 00:06:10,333

GOES-U will continue NOAA’s legacy to help scientists and forecasters

00:06:10,333 --> 00:06:14,466

understand, monitor and predict our changing environment,

00:06:14,466 --> 00:06:17,466

from the oceans to outer space.

00:06:19,300 --> 00:06:23,733

The GOES Series of satellites supports NOAA’s mission to provide secure,

00:06:23,733 --> 00:06:27,966

and timely access to global environmental data and information from

100

00:06:27,966 --> 00:06:32,200

satellites and other sources to promote and protect the Nation’s security,

101

00:06:32,200 --> 00:06:36,766

environment, economy, and quality of life.
