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.
