Hi, I'm Sean O'Keefe, I'm the Administrator of the National Aeronautics and Space Administration, 00:00:00
and also the father of three kids. 00:00:21
I'm excited by the opportunities that we can provide from NASA to inspire that next generation of explorers. 00:00:24
Matter of fact, I'm here at Belmont Ridge Middle School to lend a hand on a NASA Connect activity. 00:00:31
NASA Connect lets viewers experience the exciting and important work that engineers, scientists, and technicians do every day. 00:00:36
Work that's about the future, and for which you, our next generation, will have the opportunity to pick up and carry to new heights and possibly other planets. 00:00:43
There are many hands-on and web-based activities from NASA Connect that the family can do together at home. 00:00:51
I encourage you to learn more about those activities in today's program. 00:00:56
On this episode of NASA Connect, you'll learn how weather affects our daily lives. 00:01:00
You'll see national and international scientists using satellite technology to help improve weather forecasting and improve our ability to predict long-term climate change. 00:01:05
You'll also be introduced to two NASA satellite Earth science missions, CloudSat and Calypso. 00:01:14
In your home or classroom, you will apply math, science, and technology concepts with two really cool activities. 00:01:20
All in this episode of NASA Connect, the A-Train Express. 00:01:26
Music 00:01:30
Bonjour! I'm Jennifer Pulley, and welcome to NASA Connect, the show that connects you to math, science, technology, and NASA. 00:01:59
On today's episode, we're filming on location in France. 00:02:07
Voila! As you can see, France is a beautiful European country that is rich in culture and history. 00:02:11
Here's a quick tour of some of the places we've seen during our trip to France. 00:02:17
Music 00:02:21
Music 00:02:51
As you can see, France is a great place to visit, especially when you have nice weather. 00:02:56
Speaking of the weather, what is one of the first things you want to know when you wake up in the morning? 00:03:01
Well, if you're like me, you'll think, hmm, I wonder what the weather's going to be like today. 00:03:06
You depend on information about the weather for a variety of reasons. 00:03:11
You need to decide what to wear to school, and you need to plan for after-school activities if they're outdoors. 00:03:15
Do you realize that the weather in the United States can have a significant effect on what the weather will be like here in France? 00:03:20
Storms heading eastward from the Atlantic coast can bring wind and rain to Europe a few days later. 00:03:28
We truly live in a global society where we all are interconnected in some way. 00:03:34
Today's program will focus on predicting weather and climate change. 00:03:39
You will learn that we need to work together internationally to answer some of the questions that Earth scientists from around the world ask every day. 00:03:43
But before we get to those questions, let's first learn about the fundamentals of weather and climate. 00:03:51
During the course of the program, you will be asked to answer several inquiry-based questions. 00:03:57
After the questions appear on the screen, your teacher will pause the program to allow you time to answer and discuss the questions. 00:04:02
This is your time to explore and become critical thinkers. 00:04:10
Students working in groups take a few minutes to answer the following questions. 00:04:14
How is weather different from climate? 00:04:19
List and discuss various kinds of weather you have experienced. 00:04:22
What are some factors that determine weather? 00:04:27
What climate do you live in? 00:04:30
It's now time to pause the program and answer the questions. 00:04:32
Okay, guys, let's talk about weather. 00:04:36
Basically, weather is the daily condition of the Earth's atmosphere. 00:04:39
Weather is produced by the interaction of several factors, which include heat, air pressure, winds, and moisture. 00:04:43
Let's briefly look at each one of those factors. 00:04:51
Heat, transferred from the sun, is absorbed by the Earth and spread through the atmosphere. 00:04:54
Air temperature varies from place to place because the sun's rays strike the Earth at different angles. 00:05:00
Air pressure is the measure of the force of the air pressing down on the Earth's surface. 00:05:07
Air pressure depends on the density of the air. 00:05:13
Denser air exerts more pressure than less dense air. 00:05:16
Air pressure on the Earth can vary considerably from location to location due to unequal heating of the atmosphere. 00:05:20
These air pressure differences cause the movement of air, which we call wind. 00:05:28
Finally, the amount of moisture in the air, called relative humidity, also influences weather. 00:05:33
Moisture in the atmosphere condenses, causing clouds to develop and precipitation to fall to the Earth. 00:05:39
So, have you come up with the difference between weather and climate? 00:05:45
I said earlier that weather is the daily condition of the Earth's atmosphere. 00:05:50
But what about climate? 00:05:53
Well, for most of us, climate means a location is hot, cold, wet, or dry. 00:05:55
You see, climate is the average weather conditions for a specific region over an extended period of time. 00:06:01
The climate of any place is determined by two main factors, temperature and precipitation. 00:06:08
The Earth is divided into three major climate zones based on the average temperature of these zones. 00:06:14
They are the tropical, temperate, and polar zones. 00:06:21
Can you determine what climate zone you live in? 00:06:25
To learn more about weather and climate, check out the following NASA website. 00:06:28
Have you ever been in a situation where the weather forecast called for sunny skies, yet it ended up raining all day long? 00:06:33
You think, oh, if I only had my umbrella. 00:06:41
But you know, guys, the job of predicting weather accurately is a difficult one because our atmosphere, it's constantly changing. 00:06:44
You see, in order to predict the weather accurately for the hours and days ahead, 00:06:51
weather forecasters must analyze information they receive from a number of sources, 00:06:56
including local weather observers, weather balloons, weather stations, and satellites. 00:07:01
Speaking of satellites, NASA has a train of satellites called the Afternoon Constellation, 00:07:07
nicknamed the A-Train, which are orbiting the Earth. 00:07:13
And they're collecting all sorts of data, including data that will help predict weather and climate change. 00:07:16
Two additional satellites, CloudSat and Calypso, will soon be launched to be a part of that train. 00:07:22
CloudSat will help improve weather prediction by studying the different aspects of clouds, as its name implies. 00:07:28
Calypso will help predict climate change and how aerosols or particles affect the Earth's atmosphere. 00:07:34
Later on in the program, Dr. Didier Tonray will tell us all about aerosols. 00:07:41
But first, let's visit with Dr. Graham Stevens. 00:07:46
He's the principal investigator on the CloudSat mission. 00:07:49
Thank you, Jennifer. 00:07:52
We rely on accurate weather predictions for many activities. 00:07:55
Farmers need to know the best times to plant and harvest their crops. 00:07:58
Airplane takeoffs, landings, and flight paths are scheduled according to local weather conditions. 00:08:02
Weather forecasts alert people to severe storms that could endanger life or property. 00:08:08
And most people want to know what the weather will be like as they go to and from work and school or plan outdoor activities. 00:08:12
But do you think weather predictions or forecasts are always correct? 00:08:20
What do you think causes errors in weather forecasts? 00:08:24
You know, Jennifer is right when she stated that weather prediction is difficult. 00:08:27
The atmosphere is constantly changing and even though we receive weather data from a variety of sources 00:08:31
such as weather stations, satellites, weather balloons, and ground-based observers, 00:08:36
it is still impossible to predict the weather correctly 100% of the time. 00:08:42
One of the ways of improving our prediction of weather and climate 00:08:46
is to develop new technologies that helps us understand how the atmosphere works. 00:08:50
A new satellite that will help improve weather prediction is NASA's CloudSat satellite. 00:08:54
CloudSat will provide the first vertical cloud profiling from space, improving weather and climate forecasts. 00:08:58
Before we continue with the specifics of the CloudSat mission, 00:09:04
here are a few questions I would like you and your peers to discuss and answer. 00:09:08
What is a cloud? 00:09:12
What types of clouds exist? 00:09:14
Which clouds make which weather? 00:09:16
Why is it important to study clouds? 00:09:18
It's now time to pause the program. 00:09:20
So how did you do with your questions? 00:09:22
You know, clouds are all made of water. 00:09:24
Sometimes they are made of tiny drops, far apart and held up by the wind. 00:09:26
Other times they are made of big drops, held up for a while by very strong upward winds inside the cloud. 00:09:30
In this kind of cloud, the drops become too heavy to stay up, so they fall to earth as rain, 00:09:36
or if it's cold enough, they fall to earth as snow, hail, or sleet. 00:09:41
Clouds are classified based on three factors. 00:09:44
Their shape, the altitude at which they occur, and whether they are producing precipitation. 00:09:47
Clouds come in three basic shapes. 00:09:52
Cumulus clouds, which are heaped and puffy. 00:09:54
Stratus clouds, which are layered. 00:09:56
And cirrus clouds, which are wispy. 00:09:59
Clouds also occur in three altitude ranges, specifically the altitude of the cloud base. 00:10:01
High clouds, which occur above 6,000 metres and designated by cirrus, 00:10:06
or cirro, are cirrus, cirrocumulus, and cirrostratus. 00:10:10
Middle clouds, which occur between 2,000 and 6,000 metres and are designated by alto, 00:10:17
are altocumulus and altostratus. 00:10:22
Low clouds, which occur below 2,000 metres are stratus, nimbostratus, 00:10:26
cumulus, stratocumulus, cumulonimbus, and fog. 00:10:33
I bet you didn't think fog was a cloud. 00:10:38
It's a cloud that touches the ground. 00:10:41
Clouds that incorporate the word nimbus, or the prefix nimbo, 00:10:43
are clouds from which precipitation is falling. 00:10:47
Can you think of another type of cloud? 00:10:50
I'll leave the answer to that question up to you. 00:10:52
So how many of you are wondering how to keep all those clouds in order? 00:10:54
You know, it's tough even for me. 00:10:58
That's why I use this globe cloud chart as a reference. 00:11:00
You'll learn more about globe later in the program. 00:11:03
So why is it important to study clouds? 00:11:06
Clouds exert an enormous influence on our weather and climate. 00:11:09
They are nature's way of moving fresh water from place to place on Earth. 00:11:12
Clouds play a very important part in maintaining Earth's temperature. 00:11:16
We need to understand how clouds reflect the sun's energy back into space 00:11:19
or trap the Earth's energy in the atmosphere. 00:11:24
We call this Earth's radiation budget. 00:11:26
Using the CloudSat satellite, for the very first time, 00:11:29
we'll be able to measure the altitude and properties of clouds. 00:11:32
CloudSat radar will slice through the atmosphere, 00:11:35
providing vertical cross-sectional view of clouds 00:11:38
and furnish new weather and climate data, 00:11:41
including cloud layer thickness, cloud top and base altitude, 00:11:44
and water and ice contents. 00:11:49
Existing space-based systems only observe the uppermost layer of clouds 00:11:51
and cannot reliably detect the presence of multiple cloud layers 00:11:55
nor determine the cloud water and ice content. 00:11:58
The penetration of CloudSat's radar into and through clouds 00:12:01
will yield a new capability that fills a critical gap 00:12:05
in existing and planned space-borne observational systems. 00:12:08
With this new technology, CloudSat will improve weather predictions, 00:12:11
increasing the accuracy of severe weather, hurricanes, and flood warnings. 00:12:15
And now, Jennifer, I think the students are ready to size up the clouds. 00:12:20
Back to you. 00:12:25
Thanks, Dr. Stephens. 00:12:28
I really had no idea how much the clouds impacted our weather. 00:12:30
Well, now it's time to see how much you've learned, 00:12:33
and it's time for you to size up the clouds. 00:12:36
Students from the School of International Studies at Meadowbrook in Norfolk, Virginia, 00:12:38
will preview Part 1 of this program's hands-on activity. 00:12:43
NASA Connect asks us to show you this program's hands-on activity. 00:12:48
In this activity, you will set up three simulated clouds 00:12:53
representing three different cloud types. 00:12:57
You will use different methods to estimate precipitation content in each cloud type. 00:12:59
The precipitation from each cloud will be released, 00:13:05
and you will compare your estimates with what is actually occurring on the ground. 00:13:08
In addition to learning about weather forecasting, 00:13:14
we will also be using math skills like estimation, percentages, averages, and ratios. 00:13:16
You can download a copy of the Educator Guide containing directions 00:13:22
and a list of materials from the NASA Connect website. 00:13:25
Teachers should cut a three-quarter inch diameter hole 00:13:29
in the center of the bottom of three different foam cups. 00:13:32
Cover the hole with a Post-It note. 00:13:37
Place about one ounce of M&M's in a plastic bag. 00:13:39
Twist the bag tightly and tie the excess bag in a knot. 00:13:42
Cut off the excess to make a compact bundle. 00:13:47
Make a second bag following the same procedure. 00:13:50
Select any cup. 00:13:53
Pour in about half full of M&M's. 00:13:54
Then add a bundle of M&M's and fill more loose M&M's into the cup 00:13:57
until it is three-quarters full. 00:14:02
The loose M&M's will represent the amount of precipitation in each cloud. 00:14:05
Fill the second cup to about one-third full of M&M's. 00:14:10
Fill the third cup to about one-fourth full of M&M's. 00:14:14
Add a bundle of M&M's and then continue filling with loose M&M's 00:14:18
until the cup is one-half full. 00:14:22
Secure the lids on the cups by taping the joint with masking tape or transparent tape. 00:14:24
Invert the cups and label each cup cloud type X, Y, and Z. 00:14:30
Below this, write the actual capacity of the cups chosen. 00:14:35
Line up the cups on a table. 00:14:39
Students will estimate how many ounces of precipitation each cloud type contains. 00:14:41
Write the estimate onto the data sheet. 00:14:47
Next, remove the post-it note and shine a flashlight into the hole. 00:14:49
Make a new estimate of how many ounces of precipitation each cloud type contains 00:14:53
and record it on your data sheet. 00:14:58
Do this for each cloud type. 00:15:00
Choose a person to weigh each cloud type cup on a scale. 00:15:02
Record the weight ounces. 00:15:07
Remember, weight ounces do not equal volume ounces. 00:15:09
Once you have collected all of the data, you will be able to use it 00:15:13
Once you have collected all of the data, you will revise your precipitation estimate. 00:15:17
Based on your data, answer these questions. 00:15:22
How does the data compare with your estimates? 00:15:24
What factors might cause differences? 00:15:27
If you had another cloud type of a different size, 00:15:30
would the data collected make for a more accurate precipitation forecast? 00:15:34
Discuss these findings with your class. 00:15:39
Great job, you guys! 00:15:44
Okay, now let's review. 00:15:45
First, we learned the difference between weather and climate. 00:15:47
Then, we learned how weather is produced by several factors like heat energy and moisture. 00:15:51
Next, Dr. Graham Stevens told us how the CloudSat satellite 00:15:57
will be able to help improve weather prediction across the globe. 00:16:01
Now let's focus our attention on aerosols, climate changes, and Calypso. 00:16:09
For that, we're going to head to the Space Agency of France, or CNES. 00:16:14
What NASA is to America, CNES is to France. 00:16:19
So, let's go speak with Dr. Didier Tonray. 00:16:23
He's a principal investigator of Parasol and a co-investigator for the Calypso mission. 00:16:26
Calypso is a satellite that's being built by both France and the United States. 00:16:32
Launch! 00:16:37
Merci, Jennifer. 00:16:40
The climate of the Earth has not remained constant through the course of time. 00:16:41
It has changed. 00:16:46
In general, living things have affected changes in climate, 00:16:47
and changes in climate have affected living things. 00:16:52
Working in groups, see if you can answer the following question. 00:16:55
What are some reasons why our climate has changed over time? 00:16:59
Teacher, you may now pause the program so students can answer the question. 00:17:04
From reports of increasing temperature, we think that the Earth's climate is maybe changing. 00:17:08
But the processes behind these changes are not as clear. 00:17:14
Two of the biggest uncertainties in understanding and predicting climate change 00:17:17
are the effect of clouds and aerosols. 00:17:22
The Calypso, or Cloud Aerosol LiDAR and Infrared Pathfinder Satellite Observation Satellite mission 00:17:25
will help us answer significant questions about climate processes 00:17:32
by providing new information on clouds and aerosols. 00:17:36
Dr. Stephens provided you with some information on clouds, 00:17:40
so now let's concentrate on aerosols. 00:17:43
What are aerosols? 00:17:46
Aerosols are tiny particles suspended in the air. 00:17:48
Some occur naturally, originating from volcanoes, dust storms, forests and grassland fires, 00:17:51
living vegetation and sea spray. 00:17:58
Human activities, such as the burning of fossil fuels 00:18:01
and the alteration of natural surface cover, also generate aerosols. 00:18:04
Average over the globe, aerosols made by human activities 00:18:09
currently account for 10% of the total amount of aerosols in our atmosphere. 00:18:13
Most of that 10% is concentrated in the northern hemisphere. 00:18:19
Can you think of a reason why? 00:18:23
We have much to learn about the way aerosols affect global and regional climate. 00:18:25
We don't know in what regions of the planet the amount of atmospheric aerosol 00:18:29
is increasing, decreasing or remaining constant. 00:18:33
Overall, we don't know whether aerosols are warming or cooling the planet. 00:18:37
So why do we care about aerosols? 00:18:42
Aerosols tend to cause cooling of the Earth's surface immediately below them. 00:18:45
Because they reflect sunlight back into space, 00:18:50
aerosols have a direct cooling effect by reducing the amount of solar radiation 00:18:52
that reaches the surface. 00:18:57
It is thought that aerosol cooling may partially offset expected global warming 00:18:59
that is attributed to increases in the amount of carbon dioxide 00:19:03
and other gases from human activity. 00:19:07
Did you realize that if there were no aerosols in the atmosphere, 00:19:10
there would be no clouds? 00:19:13
What can you say about the relationship between clouds and aerosols? 00:19:15
Aerosols are believed to have an indirect effect on climate 00:19:19
by changing the properties of clouds. 00:19:22
As aerosol concentration increases within a cloud, 00:19:25
the water in the cloud gets spread over many more particles, 00:19:28
each of which is correspondingly smaller. 00:19:32
In this way, changing aerosol in the atmosphere 00:19:36
can change the frequency of cloud occurence, cloud thickness and rainfall amounts. 00:19:39
Also, clouds with low aerosol concentration and few large droplets 00:19:45
do not scatter light well 00:19:50
and allow much of the sunlight to pass through and reach the surface. 00:19:52
However, the high aerosol concentration in these clouds 00:19:56
allows for the formation of many small liquid water droplets. 00:20:00
Up to 90% of visible radiation or light is reflected back to space by such clouds 00:20:04
without reaching Earth's surface. 00:20:12
Probably the best-known evidence of the effect of aerosols in the atmosphere 00:20:14
occurred in 1991. 00:20:18
A severe volcanic eruption from Mount Pinatubo, Philippines, 00:20:20
put an estimated 20 million tons of sulfur dioxide into the atmosphere. 00:20:24
Aerosols from that eruption stayed in the atmosphere so long 00:20:29
that average global temperature over the following year cooled by about half a degree. 00:20:33
So, earlier in the program, Jennifer was right 00:20:38
in that weather in the United States affects the weather here in France 00:20:41
and all over the globe. 00:20:45
And the reverse is true. 00:20:47
Scientists have been observing clouds and aerosols globally from space for many years 00:20:48
using sensors that measure the amount of energy leaving Earth. 00:20:54
The sensors observe how clouds and aerosols vary with latitude and longitude 00:20:58
but provide little information of what is inside the clouds 00:21:03
or on how they vary with altitude. 00:21:07
For the first time, the CALIPSO satellite will provide vertical, 00:21:10
curtained-like images of the atmosphere on a global scale using a LiDAR. 00:21:14
The LiDAR technique is similar to radar in operation, 00:21:19
but LiDAR uses short pulses of laser light instead of radio waves to prompt the atmosphere. 00:21:22
The LiDAR data from CALIPSO will allow us to determine precisely 00:21:29
the altitudes of clouds and aerosol layers and the extent of layer overlap 00:21:34
to identify the composition of clouds and to estimate the abundance and sizes of aerosols. 00:21:39
CALIPSO is a highly advanced research tool to study the Earth's atmosphere 00:21:44
and will provide the international community with a data set 00:21:49
that is essential for a better understanding of the Earth's climate. 00:21:53
With more confidence in climate model predictions, 00:21:57
international leaders will be able to make more informed policy decisions about global climate change. 00:22:00
So the next time you wake up on a hazy summer day, 00:22:08
you can tell your friends that the haziness may be caused by sandstorms 00:22:11
or volcanic eruptions that occur halfway around the world. 00:22:15
Now back to you, Jennifer. Au revoir. 00:22:20
Merci, Dr. Tonray. 00:22:26
Well, now that you are experts on aerosols, 00:22:28
let's head to Collège Cantolando, located in Bordeaux, France, 00:22:31
for part deux of this program's hands-on activity, the Globe Aerosol Protocol. 00:22:35
In this activity, called Aerosols Protocol, 00:22:55
you will use a sun photometer to measure the aerosol optical thickness of the atmosphere 00:22:58
or how much of the sun's light is scattered or absorbed by particles suspended in the air. 00:23:04
Remember, you can download a copy of the educator guide 00:23:11
containing directions and list of materials from the NASA Connect website. 00:23:14
When you are ready to go outside, put your sun photometer in an insulated bag 00:23:19
to keep it at room temperature. 00:23:23
Putting your sun photometer in a bag will help minimize any temperature sensitivity problems. 00:23:25
To begin taking measurements with your sun photometer, 00:23:31
flip the power switch on and then select the green channel. 00:23:33
Hold the instrument in front of you about chest high. 00:23:37
Point the sun photometer at the sun 00:23:40
and then find the spot made by the sun as it shines through the front alignment bracket. 00:23:43
Remember, guys, never look directly into the sun. 00:23:49
Use the mark on the rear alignment bracket as a guide 00:23:52
to align the sunspot until it rests on the color dot. 00:23:56
It is normal for the readout to fluctuate within a few millivolts. 00:24:00
Record only the highest reading that you see over a period of about 15 seconds. 00:24:04
Record the value on the data sheet and the time of the reading to within 15 seconds. 00:24:10
Now take the dark voltage reading. 00:24:15
Cover the two holes on the sun photometer. 00:24:18
Record the value of the dark voltage reading on the data sheet. 00:24:21
Switch to the red channel. 00:24:25
Record the maximum voltage and the time just as you did with the green channel. 00:24:27
Then take the dark voltage reading again just like before. 00:24:33
You need to repeat the process for the green and red channels two more times, 00:24:37
giving you a total of three data points for each channel. 00:24:42
Next, using your cloud chart as a guide, observe and record cloud conditions. 00:24:46
Determine what types of clouds are in the sky. 00:24:51
Record your observation on the data chart. 00:24:54
Next, determine the percentage of cloud cover and record the value on the data sheet. 00:24:57
Now you need to observe the sky conditions. 00:25:02
What is the sky color? Is the sky clear or hazy? 00:25:05
Is the sky obscured by fog, smoke, or haze? 00:25:09
Record these observations on the data sheet. 00:25:14
Finally, record the current temperature. 00:25:16
When you get back into your classroom, log on to the following website. 00:25:19
You will record all your data into the database. 00:25:24
The database will automatically convert your voltage readings to aerosol optical thickness. 00:25:27
To learn more about assessing a sun photometer, check out the NASA Connect website. 00:25:32
Très bien. Super job, you guys. 00:25:40
You sure did collect a lot of data in your aerosol protocol. 00:25:42
Now, don't throw it away because it could be useful to scientists from around the world. 00:25:45
Say, how would you like to be a part of a really cool international science program? 00:25:50
Well, Dr. Diane Robinson, Calypso Outreach Director from Hampton University, 00:25:56
and Dr. Teresa Kennedy with Globe International can tell you more. 00:26:01
Thanks, Jennifer. Those are great activities that can be used with Globe and Calypso, 00:26:05
the satellite being built right here at the Alcatel building in Cannes, France. 00:26:10
If you would like to participate with this experiment 00:26:15
or other Earth science activities related to satellite observation, 00:26:18
the Globe program is actively looking for students to work with scientists worldwide. 00:26:21
Globe is a cooperative worldwide effort to collect environmental observations 00:26:25
into a large database on the Internet, 00:26:29
and we welcome the French to be the newest members to Globe. 00:26:31
Students around the world collect real data in all Earth science areas. 00:26:34
The measurements collected by students are sent to the Globe database via the Web or e-mail 00:26:38
and used by students and scientists around the world. 00:26:42
The student information is used in a real way with the data collected by scientists and satellites 00:26:45
to give us a greater idea about how the environment works. 00:26:50
Once submitted, these data are publicly available on the Globe website 00:26:53
and are displayed graphically with Globe visualization tools. 00:26:57
An important aspect of the program is that students are encouraged to communicate directly with Globe scientists 00:27:00
to better understand the importance and impact of their data. 00:27:05
Another important aspect is that the information you collect 00:27:08
can and does make a difference to understanding our world around us. 00:27:11
More than a million students in over 14,000 schools have joined the Globe effort, 00:27:15
and the numbers are growing. 00:27:20
Won't you join the effort? 00:27:22
For more information, go to our website at www.globe.gov. 00:27:24
Back to you, Jennifer. 00:27:28
Thanks, Diane and Teresa. 00:27:32
Well, guys, that wraps up another episode of NASA Connect. 00:27:34
Students, don't forget to check out the website for this program's Web activities and the student challenge. 00:27:37
Hey, got a question, comment, or suggestion? 00:27:44
Then e-mail them to connect at lark.nasa.gov. 00:27:47
So until next time, stay connected to math, science, technology, and NASA. 00:27:51
Au revoir. 00:27:57
