00:00:04.667 --> 00:00:10.667
[upbeat music]

00:00:12.533 --> 00:00:14.533
- "OUR WORLD."

00:00:21.233 --> 00:00:22.734
- OH, HEY, EVERYBODY.

00:00:22.734 --> 00:00:25.166
I'M LILY,
AND THIS IS "OUR WORLD."

00:00:25.166 --> 00:00:28.467
I'M JUST LOOKING
AT SOME OLD FAMILY PHOTO ALBUMS.

00:00:28.467 --> 00:00:30.467
I LOVE LOOKING AT PICTURES.

00:00:30.467 --> 00:00:33.633
I ALSO LOVE TAKING PICTURES--

00:00:33.633 --> 00:00:35.734
PICTURES OF MY FAMILY
AND FRIENDS,

00:00:35.734 --> 00:00:37.767
PICTURES OF PLANTS
AND ANIMALS,

00:00:37.767 --> 00:00:41.367
PICTURES OF ANYTHING
THAT CATCHES MY EYE.

00:00:41.367 --> 00:00:42.600
[camera shutter clicks]

00:00:42.600 --> 00:00:44.533
AND WHEN I'M FINISHED
TAKING PICTURES,

00:00:44.533 --> 00:00:46.333
I LIKE TO PUT THEM
ON MY COMPUTER

00:00:46.333 --> 00:00:48.333
AND ADD MUSIC
AND SPECIAL EFFECTS

00:00:48.333 --> 00:00:50.500
AND SHOW THEM
TO ALL MY FRIENDS.

00:00:50.500 --> 00:00:52.300
DID YOU KNOW THAT NASA
TAKES PICTURES

00:00:52.300 --> 00:00:54.400
OF ALL SORTS OF THINGS TOO?

00:00:54.400 --> 00:00:56.967
FARAWAY GALAXIES, PLANETS,

00:00:56.967 --> 00:00:58.900
THE MOON, EVEN EARTH.

00:00:58.900 --> 00:01:01.133
SOME OF MY FAVORITE PICTURES
OF THE EARTH

00:01:01.133 --> 00:01:03.433
WERE TAKEN BY ASTRONAUTS
ORBITING OUR WORLD

00:01:03.433 --> 00:01:05.767
ON THE INTERNATIONAL
SPACE STATION.

00:01:05.767 --> 00:01:09.200
HERE, CHECK OUT THIS VIDEO
I FOUND ON THE NASA WEBSITE.

00:01:09.200 --> 00:01:12.433
THIS IS ASTRONAUT JEFF WILLIAMS
TALKING ABOUT THE VIEW

00:01:12.433 --> 00:01:15.700
AND THE KIND OF PICTURES
ASTRONAUTS TAKE WHEN ON ORBIT.

00:01:15.700 --> 00:01:18.533
- WE DO MANY THINGS
ON BOARD THE SPACE STATION,

00:01:18.533 --> 00:01:20.867
BUT ONE OF THE UNIQUE THINGS
IS TO VIEW THE EARTH

00:01:20.867 --> 00:01:23.266
FROM A VERY UNIQUE
VANTAGE POINT.

00:01:23.266 --> 00:01:28.467
WE TRAVEL AROUND THE EARTH
IN ORBITS THAT LAST 90 MINUTES

00:01:28.467 --> 00:01:31.200
AT 17,500 MILES AN HOUR.

00:01:31.200 --> 00:01:33.600
WE COVER THE MAJORITY
OF THE EARTH.

00:01:33.600 --> 00:01:36.233
THE EARTH IS FULL
OF AN INCREDIBLE ABUNDANCE

00:01:36.233 --> 00:01:40.367
AND VARIETY OF WEATHER
AND TERRAIN.

00:01:40.367 --> 00:01:42.834
- JUST SO YOU KNOW,
"TERRAIN" REFERS

00:01:42.834 --> 00:01:45.567
TO THE FEATURES OF THE LAND.

00:01:45.567 --> 00:01:48.900
- AND WE NEVER TIRE
OF LOOKING AT THAT TERRAIN,

00:01:48.900 --> 00:01:50.934
MAKING OBSERVATIONS,

00:01:50.934 --> 00:01:53.400
MAKING PHOTOGRAPHY
OF THE TERRAIN,

00:01:53.400 --> 00:01:54.600
OF THE DIFFERENT MOUNTAINS

00:01:54.600 --> 00:01:56.433
AND THE GLACIERS
AND THE DESERTS,

00:01:56.433 --> 00:01:57.700
WEATHER PATTERNS,

00:01:57.700 --> 00:02:01.934
THE HORIZONS,
THE SUNSETS AND SUNRISES.

00:02:01.934 --> 00:02:05.934
IT'S JUST AN INCREDIBLE VARIETY
OF THINGS TO VIEW

00:02:05.934 --> 00:02:08.166
ON THE EARTH
FROM THE ISS.

00:02:08.166 --> 00:02:10.500
- WOW, WHAT AMAZING PICTURES
OF EARTH.

00:02:10.500 --> 00:02:13.233
AND THE ASTRONAUTS
PASS OVER ALL THOSE PLACES

00:02:13.233 --> 00:02:15.100
IN JUST A FEW MINUTES.

00:02:15.100 --> 00:02:16.800
IT WOULD TAKE ME A LONG TIME

00:02:16.800 --> 00:02:19.000
TO GET FROM GLACIERS
TO THE DESERT.

00:02:19.000 --> 00:02:21.066
WHAT ELSE DO YOU THINK
THE ASTRONAUTS CAN SEE

00:02:21.066 --> 00:02:22.400
FROM ON ORBIT?

00:02:22.400 --> 00:02:25.000
LET'S FIND OUT.

00:02:25.000 --> 00:02:26.333
- WE CAN SEE CITIES.

00:02:26.333 --> 00:02:30.066
WE CAN SEE LARGE BRIDGES
AND STRUCTURES

00:02:30.066 --> 00:02:31.500
AND THAT SORT OF THING.

00:02:31.500 --> 00:02:34.400
WITH A LARGE LENS LIKE THIS,
JUST HANDHELD PHOTOGRAPHY,

00:02:34.400 --> 00:02:36.333
WE CAN SEE THINGS
LIKE THE PYRAMIDS,

00:02:36.333 --> 00:02:38.200
THE DETAILS IN CITIES.

00:02:38.200 --> 00:02:42.400
I LOVE TO CAPTURE
THE VERY CONGESTED CENTERS

00:02:42.400 --> 00:02:46.166
OF EUROPEAN CITIES THAT GO BACK
TO THE MEDIEVAL DAYS

00:02:46.166 --> 00:02:49.300
OR THE DETAILS OF A RIVERBED

00:02:49.300 --> 00:02:52.734
AS IT RISES AND FALLS
DURING THE SEASONS OF THE YEAR

00:02:52.734 --> 00:02:54.433
OR THE DETAILS OF A GLACIER.

00:02:54.433 --> 00:02:57.967
ANOTHER EXAMPLE WOULD BE
THE DETAILS OF SAND DUNES

00:02:57.967 --> 00:03:01.934
AND THE INCREDIBLE VARIETY
OF GEOMETRIC SHAPES

00:03:01.934 --> 00:03:04.000
OF THOSE SAND DUNES
AROUND THE WORLD.

00:03:04.000 --> 00:03:07.367
WE CAN ALSO CATCH THINGS
LIKE OCEAN CURRENTS,

00:03:07.367 --> 00:03:11.000
ESPECIALLY WHEN THE SUN
IS REFLECTING OFF THE OCEAN

00:03:11.000 --> 00:03:13.667
OR THE WATER BELOW
AS WE PASS OVER.

00:03:13.667 --> 00:03:15.266
SO ALL OF THAT JUST--

00:03:15.266 --> 00:03:19.400
IT PROVIDES
A VERY RICH SUBJECT MATTER

00:03:19.400 --> 00:03:20.834
FOR VIEWING THE EARTH.

00:03:20.834 --> 00:03:24.734
- BOY, I CAN'T WAIT UNTIL
I GROW UP AND CAN WORK AT NASA.

00:03:24.734 --> 00:03:27.500
DO YOU KNOW THERE ARE PEOPLE
WORKING THERE RIGHT NOW

00:03:27.500 --> 00:03:29.867
WHO STARTED OUT IN PROGRAMS
AS STUDENTS?

00:03:29.867 --> 00:03:32.200
MAYBE I'LL GET A JOB
IN MISSION CONTROL

00:03:32.200 --> 00:03:34.033
SO I CAN BE
ONE OF THE FIRST ONES

00:03:34.033 --> 00:03:35.967
TO SEE THOSE NEAT PICTURES.

00:03:35.967 --> 00:03:40.133
- NOW, WE'RE NOT THE ONLY ONES
THAT CAN SEE THE PHOTOGRAPHY

00:03:40.133 --> 00:03:42.767
AND THE VIEW OUT THE WINDOW
FROM ISS.

00:03:42.767 --> 00:03:44.100
YOU CAN TOO.

00:03:44.100 --> 00:03:45.800
THERE'S A COUPLE OF WAYS
YOU CAN DO IT.

00:03:45.800 --> 00:03:50.567
ALL OF THE PHOTOGRAPHY WE TAKE
IS PRESENT ON THE INTERNET,

00:03:50.567 --> 00:03:52.367
AND YOU CAN FIND IT
BY SEARCHING

00:03:52.367 --> 00:03:55.100
FOR "ASTRONAUT
EARTH PHOTOGRAPHY,"

00:03:55.100 --> 00:03:57.100
AND THEN GO INTO THAT DATABASE
AND SEARCH THAT

00:03:57.100 --> 00:04:01.133
FOR PERHAPS AREAS
AROUND WHERE YOU LIVE.

00:04:01.133 --> 00:04:03.233
- OOH, I SHOULD BOOKMARK
THAT SITE.

00:04:03.233 --> 00:04:06.100
I'LL BET THERE'S TONS
OF BEAUTIFUL PICTURES ON THERE.

00:04:06.100 --> 00:04:09.266
- WE ALSO HAVE A STUDENT PROGRAM
CALLED EARTHKAM,

00:04:09.266 --> 00:04:13.967
AND I ENCOURAGE YOU TO GO
ON NASA.GOV AND FIND EARTHKAM

00:04:13.967 --> 00:04:17.500
AND SEE WHAT PRODUCTS
THAT STUDENTS AROUND THE WORLD

00:04:17.500 --> 00:04:20.433
HAVE TAKEN
BY PROGRAMMING A CAMERA,

00:04:20.433 --> 00:04:24.700
A CAMERA THAT WE PUT
IN A WINDOW HERE.

00:04:24.700 --> 00:04:26.667
IT'S A CAMERA JUST LIKE THIS,

00:04:26.667 --> 00:04:30.166
AND IT OFTEN HAS
THIS LENS ON IT,

00:04:30.166 --> 00:04:32.100
A 180-MILLIMETER LENS.

00:04:32.100 --> 00:04:35.100
WE PUT IT IN THE CAMERA,
CONNECT IT UP TO A COMPUTER,

00:04:35.100 --> 00:04:37.233
AND THE STUDENTS
THAT PARTICIPATE IN EARTHKAM

00:04:37.233 --> 00:04:38.767
ARE ABLE TO PROGRAM THE TIME

00:04:38.767 --> 00:04:40.934
THAT THEY WANT THE CAMERA
TO TAKE A PICTURE,

00:04:40.934 --> 00:04:42.867
AND THEY CAN PREDICT
WHERE THE ISS,

00:04:42.867 --> 00:04:44.633
WHERE THE INTERNATIONAL
SPACE STATION,

00:04:44.633 --> 00:04:47.000
WILL BE OVER LAND
AT ANY GIVEN TIME.

00:04:47.000 --> 00:04:49.433
SO IF YOU KNOW THAT
AND YOU KNOW THE ISS

00:04:49.433 --> 00:04:52.867
IS PASSING OVER A FEATURE
OF THE EARTH

00:04:52.867 --> 00:04:55.000
THAT THE STUDENTS
ARE INTERESTED IN

00:04:55.000 --> 00:04:57.433
AND THEY KNOW THE EXACT TIME
THAT THEY'RE PASSING IT,

00:04:57.433 --> 00:05:00.266
THEY PROGRAM THE CAMERA
AND TAKE THE PICTURE.

00:05:00.266 --> 00:05:02.333
SO YOU, TOO,
CAN GO ON THE INTERNET

00:05:02.333 --> 00:05:05.734
AND LOOK THROUGH THE PRODUCTS
ON THE EARTHKAM PROGRAM.

00:05:05.734 --> 00:05:09.300
- WOW, I'M GONNA HAVE TO TELL
MY BIG SISTER ABOUT EARTHKAM.

00:05:09.300 --> 00:05:10.967
SHE'S IN MIDDLE SCHOOL NOW.

00:05:10.967 --> 00:05:13.433
MAYBE HER CLASS CAN GET INVOLVED
IN TAKING PICTURES

00:05:13.433 --> 00:05:16.033
FROM THE INTERNATIONAL
SPACE STATION.

00:05:16.033 --> 00:05:17.633
SO WHAT DID WE LEARN TODAY?

00:05:17.633 --> 00:05:18.934
WE LEARNED THAT EARTH

00:05:18.934 --> 00:05:20.767
HAS MANY DIFFERENT KINDS
OF TERRAIN

00:05:20.767 --> 00:05:23.166
AND ASTRONAUTS TAKE PICTURES
OF ALL OF IT.

00:05:23.166 --> 00:05:26.100
WE LEARNED THAT ASTRONAUTS
CAN SEE HUMAN-BUILT STRUCTURES

00:05:26.100 --> 00:05:28.367
FROM THE INTERNATIONAL
SPACE STATION.

00:05:28.367 --> 00:05:31.934
AND WE LEARNED THAT STUDENTS
CAN TAKE PICTURES FROM THE ISS

00:05:31.934 --> 00:05:33.700
THROUGH THE EARTHKAM PROGRAM.

00:05:33.700 --> 00:05:36.500
TO FIND OUT MORE ABOUT A DAY
IN THE LIFE OF AN ASTRONAUT

00:05:36.500 --> 00:05:38.734
OR THE EARTHKAM PROGRAM, VISIT:

00:05:43.934 --> 00:05:46.734
SEE YOU NEXT TIME
ON "OUR WORLD."

00:05:46.734 --> 00:05:48.200
SAY, "CHEESE."

00:05:48.200 --> 00:05:49.200
[camera shutter clicks]

00:05:58.567 --> 00:06:00.633
- "OUR WORLD."
