00:00:01.050 --> 00:00:03.100
Did you know you can see penguin poop from space?

2
00:00:03.100 --> 00:00:04.080
That’s right!

3
00:00:04.080 --> 00:00:07.010
Pink piles of poop from those cute flightless birds.

4
00:00:07.010 --> 00:00:08.770
There it is right there!

5
00:00:08.770 --> 00:00:10.250


6
00:00:10.250 --> 00:00:13.900
I’ll have a krill burger with a side order of squid fries please!

7
00:00:13.900 --> 00:00:17.890
Astronauts get to see Earth from the International Space Station every day!

8
00:00:17.890 --> 00:00:18.680
Hello, there!

9
00:00:18.680 --> 00:00:19.520


10
00:00:19.520 --> 00:00:22.060
You know what else gets to Earth from space every day?

11
00:00:22.060 --> 00:00:24.390
Our amazing fleet of satellites!

12
00:00:24.390 --> 00:00:25.230


13
00:00:25.230 --> 00:00:28.560
Hi, my name is Jessica Merzdorf and I’m a NASA science writer.

14
00:00:28.560 --> 00:00:31.880
I write about earth science and satellite missions including

15
00:00:31.880 --> 00:00:32.900
Landsat!

16
00:00:32.900 --> 00:00:36.910
Landsat has been taking pictures of Earth for almost 50 years!

17
00:00:36.910 --> 00:00:39.560
Not, like, pictures that your phone takes.

18
00:00:39.560 --> 00:00:43.650
These are technically 'images,' created by a bunch of encoded bits of data.

19
00:00:43.650 --> 00:00:44.500


20
00:00:44.500 --> 00:00:48.170
From space, we can see changes to the Amazon rainforest,

21
00:00:48.170 --> 00:00:50.110
growing cities like Las Vegas,

22
00:00:50.110 --> 00:00:52.820
the shifting path of the mighty Mississippi river,

23
00:00:52.820 --> 00:00:54.860
and even penguin poop.

24
00:00:54.860 --> 00:00:56.960
Our planet is changing all the time:

25
00:00:56.960 --> 00:01:00.220
From our massive glaciers, to your own neighborhood!

26
00:01:00.220 --> 00:01:04.890
So…if you had the chance, what would you like to see with Landsat?

27
00:01:04.890 --> 00:01:05.960
[beep]

28
00:01:05.960 --> 00:01:11.130
Hi NASA, I would like to ask you a question.

29
00:01:11.130 --> 00:01:16.750
What is under the surface of a volcano?

30
00:01:16.750 --> 00:01:18.270
That’s a great question.

31
00:01:18.270 --> 00:01:22.390
Lots of times there’s a chamber of lava under the surface of a volcano.

32
00:01:22.390 --> 00:01:24.650
Here’s a picture - sorry, image

33
00:01:24.650 --> 00:01:27.830
Landsat took of Kilauea in Hawaii as it’s erupting.

34
00:01:27.830 --> 00:01:32.750
With our special technology on Landsat, we can see the heat coming out of the volcano.

35
00:01:32.750 --> 00:01:36.760
Here’s an image of Mount St. Helens Landsat took in 1979.

36
00:01:36.760 --> 00:01:41.040
And here’s the same volcano right after it erupted in 1980.

37
00:01:41.040 --> 00:01:45.100
Look how the blast from the explosion knocked down the surrounding trees.

38
00:01:45.100 --> 00:01:45.680


39
00:01:45.680 --> 00:01:47.200
Amazing, right?

40
00:01:47.200 --> 00:01:47.980


41
00:01:47.980 --> 00:01:51.100
Now it’s your turn to tell us where you would like to explore!

42
00:01:51.100 --> 00:01:54.180
What others changes do you want to see as they happen on Planet Earth?

43
00:01:54.180 --> 00:01:56.920
Let us know and you could get your question answered

44
00:01:56.920 --> 00:01:59.870
by one of our super smart scientists!

45
00:01:59.870 --> 00:02:02.900
So…where do you want to go?!

46
00:02:02.900 --> 00:02:06.528
