00:00:00,000 --> 00:00:04,190

Looking back at Earth from a million miles away,

2

00:00:04,190 --> 00:00:08,370

the Deep Space Climate Observatory will watch the August total solar eclipse

3

00:00:08,370 --> 00:00:12,390

in real time, giving scientists a unique opportunity to study our

4

00:00:12,390 --> 00:00:16,600

solar powered planet. NASA’s Earth Polychromatic Imaging Camera,

5

00:00:16,600 --> 00:00:20,600

called EPIC, will capture images of the moon’s shadow

6

00:00:20,600 --> 00:00:24,700

passing over Earth. A team of scientists will combine data from EPIC

7

00:00:24,700 --> 00:00:28,710

with measurements taken on the ground to learn more about how the sun’s energy

8

00:00:28,710 --> 00:00:32,710

is absorbed and reflected in Earth’s atmosphere.

9

00:00:32,710 --> 00:00:36,720

Clouds affect how much of the sun’s energy reaches Earth, which can be difficult

10

00:00:36,720 --> 00:00:40,820

to calculate without knowing how each cloud blocks, absorbs or transmits light.

11

00:00:40,820 --> 00:00:44,830

Like a giant cloud, the moon blocks out the sun’s energy

12

00:00:44,830 --> 00:00:48,920

during the solar eclipse. Because we already know the exact shape

13

00:00:48,920 --> 00:00:52,930

and makeup of the moon, scientists can use the natural phenomenon to develop

14

00:00:52,930 --> 00:00:56,940

new calculations that could improve estimates of Earth’s energy system

15

00:00:56,940 --> 00:01:00,950

and answer questions about Earth’s climate.

16

00:01:00,950 --> 00:01:04,960

NASA has studied the sun and Earth relationship for more than 40 years.

17

00:01:04,960 --> 00:01:13,974

This year, NASA is launching two instruments to further study Earth’s energy system.
