Hi, I'm Leland Melvin, former NFL player, engineer, and now NASA astronaut. 00:00:00
NASA's looking for the next generation of explorers, and I'm here to promote careers 00:00:18
in science, technology, engineering, and mathematics. 00:00:22
In today's special edition of NASA Connect, host Jennifer Pulley will show you the world's 00:00:26
premier space convention. 00:00:31
It's called World Space Congress 2002, the new face of space. 00:00:33
You will see how science, technology, engineering, and mathematics are being used to develop 00:00:37
the world's vision of space exploration over the next 10 years and beyond. 00:00:42
You'll see great exhibits, new technologies, and students who are dreaming of becoming 00:00:47
the next generation of space explorers. 00:00:51
Bianca Baker from the NASA Sci-Files will be on location to show you a really cool 00:00:54
math game called TIVI that will enhance your basic math skills. 00:00:58
See students compete in the TIVI tournament in cooperation with NASA. 00:01:02
All this and more here on NASA Connect. 00:01:07
Hi, I'm Jennifer Pulley, and welcome to NASA Connect, the show that connects you to 00:01:24
the world of math, science, technology, and NASA. 00:01:43
I'm here in Houston, Texas at the World Space Congress 2002. 00:01:47
Let's take a quick preview of what we're going to see. 00:01:52
So, what is World Space Congress? 00:02:23
Well, it's the largest scientific, technical, and space exhibition event ever. 00:02:26
More than 13,000 international space leaders in industry, science, and engineering have 00:02:32
gathered right here in Houston, Texas. 00:02:37
It brings together international space leaders and decision makers to share their knowledge 00:02:39
and experiences, providing a guiding vision for an improved future. 00:02:44
The very people who will populate that future and serve as its leaders are the world's brightest 00:02:48
and best students and young space professionals. 00:02:53
In fact, this global event brings together over 10,000 educators, young professionals, 00:02:56
and students from more than 30 countries. 00:03:02
And speaking of students, hey, look who's here. 00:03:05
It's Bianca Baker from the NASA Sci-Files. 00:03:08
Hey, Jennifer. 00:03:10
Hey, Bianca. 00:03:11
Shouldn't you be in school? 00:03:12
My math teacher asked me to stop by and check out some math activities and bring back to 00:03:14
the classroom. 00:03:17
You know, that's a great idea. 00:03:18
There are so many math activities here. 00:03:19
I heard about a math tournament called the Chibi Tournament in cooperation with NASA. 00:03:20
I think I'm going to check it out. 00:03:24
Fill you in later. 00:03:26
That sounds great. 00:03:27
While Bianca checks out the math tournament, let's visit some of the exhibits here. 00:03:28
Hey, guys. 00:03:40
We're here at NASA's Commercialization Exhibit. 00:03:41
And I'm here with Mike Weingarten. 00:03:43
And he works at NASA Headquarters in Washington, D.C. 00:03:45
Now, Mike, when I hear commercialization, well, what is commercialization? 00:03:48
I think of TV commercials. 00:03:52
No, that's not exactly it. 00:03:54
What our program does is we actually work to bring space technology back down to Earth 00:03:56
so that people can buy products made from space technology and use it in their everyday lives. 00:04:00
Any people? 00:04:06
Yeah, we've got a whole wide range of products that we're working on or that we've developed in the past. 00:04:07
Well, here are some really neat things. 00:04:12
Just as an example, NASA developed the anti-fog coatings that are currently being used in ski goggles 00:04:14
that you can buy at your local store. 00:04:19
Those come from the shuttle main windows. 00:04:21
We also worked on gold coatings for sunglasses that come from the visors that the astronauts currently use. 00:04:23
And then another really interesting story, 00:04:29
you can actually go out and buy clogs right now that were developed from foams, 00:04:31
developed to protect the astronauts from the G-forces when the shuttle is launched. 00:04:35
Hey, Jennifer, these are just some of the cool things that we're working on at NASA. 00:04:39
Man, you guys are working on awesome stuff. 00:04:42
Well, you know, I'm going to spin off to another exhibit. 00:04:44
Okay, we're here with Sharon Cobb, and Sharon's from NASA Marshall Space Flight Center in Huntsville, Alabama. 00:04:47
Now, Sharon, it kind of looks like we're inside the International Space Station. 00:04:53
Well, we're actually in a mock-up of the space station. 00:04:58
This is the way we show people what kind of experiments we're going to be doing on the space station. 00:05:01
This is the U.S. laboratory called the Destiny Module. 00:05:04
Great. Now, what are you working on? 00:05:07
We're working on racks that house experiments that we do in the microgravity environment, 00:05:10
and there are 24 racks in the space in the U.S. laboratory. 00:05:14
They're on the ceiling, they're on the floor, they're on both sides, 00:05:17
but it doesn't really matter because the astronauts can operate from anywhere 00:05:20
because gravity doesn't pull them down to the ground. 00:05:23
Wow, so there's 24 racks in this particular module. 00:05:26
In the U.S. module. 00:05:29
Okay, and is this particular rack important? 00:05:30
This rack is important for several people. 00:05:33
In fact, it's important to everyone because we're going to be processing material science. 00:05:35
Material science is something that touches everybody's lives 00:05:39
because it involves materials that go in cars and airplanes, 00:05:42
even in the computers that we use every day. 00:05:46
They all are based on material science. 00:05:48
So we're looking at this rack to understand some of the problems that occur 00:05:51
when we form these materials on the ground so that we can produce better materials on the Earth. 00:05:55
Okay, and so tell me about what do you mean by doing things to these materials? 00:06:00
I mean, what do you want to do? 00:06:05
Are you trying to make them better? 00:06:06
We're trying to make them better. 00:06:08
We're trying to understand some of the problems that happen when you process them on Earth, 00:06:10
like light things float to the top and heavy things drop to the bottom of the container, 00:06:14
and in the microgravity environment, we don't have that problem. 00:06:19
Everything stays mixed up. 00:06:22
Wow. 00:06:24
Now, I'm going to ask about mathematics here because it's very important. 00:06:25
Is mathematics important in what you do in material science? 00:06:28
Mathematics are important in everything, but it governs everything we do in these racks. 00:06:34
It looks at how heat gets moved from one place to another. 00:06:38
There are equations that govern that. 00:06:42
There are equations that govern how liquids move around inside these experiments. 00:06:44
In fact, there's a whole group of people that on computers actually grow materials 00:06:49
and grow crystals based on mathematical equations. 00:06:53
Oh, that's so cool. 00:06:56
Now, my final question is, what do you think is the future of material science? 00:06:58
I mean, obviously, you're going to be taking them up into the International Space Station, but long term? 00:07:04
Well, what we hope to do here is gain a lot of knowledge and information 00:07:09
that helps us to produce better materials on the ground. 00:07:13
And, in fact, what we're hoping is that we'll help make some of the discoveries 00:07:16
that help us achieve space flight to long duration orbits, like to Mars maybe someday. 00:07:20
We have a lot of things that we have to solve and understand before we can do that. 00:07:27
So, hopefully, material science will help play a part in that. 00:07:30
Thanks so much. 00:07:33
Thank you. 00:07:34
Music 00:07:35
Why are we doing space research? 00:07:41
I remember when my kid, many years ago, asked me why Columbus went to America. 00:07:43
I told him because at Columbus' time, there was no refrigerator. 00:07:51
And he said, oh, what do you mean? 00:07:56
At that time, to preserve the food, it was necessary to have spices. 00:07:59
And Christopher Columbus was going to find new lands where they could take the spices. 00:08:03
So, what do I mean with this story? 00:08:11
That for every research that we are thinking to do, there is always another part of the story 00:08:13
that we have to keep in mind. 00:08:19
And it is the fact that for every research we have a counterpart here. 00:08:21
We are going to go to Mars. 00:08:26
It will be impossible to go there if we do not solve some specific problems that we have now 00:08:28
and we will continue to have in the future on the Earth. 00:08:35
I mean, going to Mars means problem of long-term isolation, 00:08:38
problem connected to the loss of calcium. 00:08:43
An astronaut loses 1.5% of calcium a month. 00:08:46
And this is a lot. 00:08:51
If you take into account how long does it take to go to Mars, 00:08:52
you know that 50% of the population on the Earth after 50 years old 00:08:55
will suffer of a specific problem which is called osteoporosis. 00:09:01
Osteoporosis is a disease connected to loss of calcium in the bones. 00:09:06
If we found a way to solve the problem of loss of calcium when the astronauts are going to Mars, 00:09:12
we will solve the same problem for millions of persons here on the Earth. 00:09:19
NASDAQ 00:09:25
Hey guys, we are here at the NASDAQ exhibit. 00:09:33
Now NASDAQ stands for the National Space Development Agency of Japan 00:09:35
and NASDAQ is Japan's core space development program. 00:09:40
It is a simple analogy. 00:09:43
NASDAQ is to Japan as NASA is to the United States. 00:09:45
And I am here with Mr. Kitahara. 00:09:49
Mr. Kitahara, what is Japan's role in the International Space Station? 00:09:51
We have three roles. 00:09:55
First, we are developing a GEM which is attached to the space station. 00:09:57
GEM stands for the Japanese Experimental Module. 00:10:02
Second, we are developing a Centrifuge Accommodation Module. 00:10:06
For NASA, we place for Kibo. 00:10:10
This is a very unique facility that generates artificial gravity to experiment 00:10:13
how microgravity affects biological processes in a space environment. 00:10:19
Third, we are developing a logistic vehicle. 00:10:25
It will transport the batteries, experimental payloads and water 00:10:29
which is needed for space station operation. 00:10:36
In your opinion, how is space research important to us right here on Earth? 00:10:39
I think the space research gives us a lot of beneficial things. 00:10:43
For example, let me give you some examples. 00:10:48
It will produce light-weighted metal, new medicine which is needed to cure very difficult diseases. 00:10:51
Does mathematics play a key role in space research? 00:11:02
I think it does. 00:11:06
To design an experimental module, we have to calculate. 00:11:08
We cannot understand phenomena without mathematics. 00:11:15
We need to analyze the data obtained. 00:11:22
And a final question, Mr. Kitahara. 00:11:25
What do you think space exploration will be like in, say, ten years? 00:11:27
Well, it's a difficult question, but I feel ten years is long or ten years short. 00:11:32
It depends. 00:11:41
About 30 years ago, Apollo astronauts landed on the moon. 00:11:43
I think that was their first space exploration. 00:11:48
And I think it will need more time to explore beyond that. 00:11:51
But I think the preparation for that will begin within ten years. 00:11:58
I think such a huge program will never be realized without international cooperation. 00:12:03
And I think it's a young generation to realize it. 00:12:11
How is math involved in the future of space transportation? 00:12:18
Hello, I'm Anna Ratzman. I'm working for the Swedish Space Corporation. 00:12:21
I'm an electrical engineer, and I've been working as a designer, as a system engineer, and as a manager. 00:12:25
You need a mathematician to be able to design the satellite, to be able to know how to launch it into space, 00:12:31
and also to be able to understand the data that you get back to solve the problems. 00:12:37
Right now, we have a satellite, Odin, looking for ozone holes. 00:12:42
You know, I have two children of my own, and they're your age. 00:12:46
And I'm worried about the pollution, how we use water. 00:12:50
And I think we can use space to get the right answer on this. 00:12:54
I just would like to say this. You need the math to be able to ask and understand the big questions. 00:12:58
We're here at the NASA Ames exhibit at World Space Congress, and I'm here with Kevin Bass. 00:13:15
Kevin works at NASA Ames Research Center in Moffett Field, California. 00:13:20
Kevin, tell me some of the cool things that you're working on. 00:13:23
I get to work with a lot of fun toys, but one of my favorites is the PSA, the Personal Satellite Assistant. 00:13:26
Tell me about the PSA. 00:13:32
The main goal of the PSA is to be a palm pilot, if you will, for each astronaut. 00:13:34
So hopefully, each astronaut will have one of these on the International Space Station. 00:13:40
It'll fly around like a little buddy up on their shoulder, 00:13:45
and it'll have a very wide array of sensors and other features, things that it can do. 00:13:48
One of them would be video teleconferencing. 00:13:54
So we can use this with anybody in the mission control or with somebody, say, the scientists that are on Earth. 00:13:57
So while the astronauts are working on a specific science experiment, 00:14:05
the scientists can actually interact with the astronaut while they're doing the experiment. 00:14:09
So can it talk to the astronauts? 00:14:14
The PSA can take voice commands. 00:14:16
So if the astronaut is curious about a specific compartment, 00:14:18
it can fly to that specific compartment and take temperature readings 00:14:21
or what other type of sensor readings that it needs to, 00:14:25
and then dictate back to the astronaut what's happening. 00:14:29
Possibly in an event of overheating or things like that, 00:14:32
it could also turn fans on and off or open and close hatch doors, things like that. 00:14:37
Now, wait a minute. 00:14:42
You said this is going to fly around. 00:14:43
How is this going to fly around the International Space Station? 00:14:46
Well, there are many different ways that it flies around. 00:14:49
It has a wide array of infrared sensors as well as the cameras and a few other functions inside 00:14:51
that it can use to fly itself around the International Space Station. 00:14:58
So it doesn't use fuel to propel itself? 00:15:03
It's propelled by fans. 00:15:05
There's 12 fans on here, and each set of fans moves it in a specific direction. 00:15:07
So I guess robotics plays a really big part, 00:15:12
will play a really big part in the future of space exploration. 00:15:15
Absolutely. 00:15:18
Robotics is the number one way to explore space without putting human lives in jeopardy. 00:15:19
I agree. 00:15:24
Thank you so much, Kevin. 00:15:25
We appreciate it. 00:15:26
Sure. 00:15:27
Well, let's see where we're off to next. 00:15:28
Music 00:15:30
Well, we just left Kevin, and we've moved around the NASA Ames exhibit, 00:15:39
and I'm here with Jim Murphy, who works at NASA Ames Research Center. 00:15:43
Jim, what are some of the technologies you're working on? 00:15:46
We have here one of the five tools that we're working on for the Mars Exploration Rover Project at JPL. 00:15:49
This is called the MER board. 00:15:56
MER stands for? 00:15:58
Mars Exploration Rover Project. 00:15:59
This is an advanced electronic collaborative whiteboard. 00:16:02
We have the ability to pull up images from the scientific database. 00:16:06
You see a typical image here, and then draw those into the whiteboard space, 00:16:10
where, with a set of tools, the scientists can mark this up, point out targets, 00:16:16
and interact and use this as their planning tool. 00:16:21
The other feature of this is the ability, then, to save what they have done with these images 00:16:27
and share them to the different groups, the other planning groups. 00:16:33
So, again, it's a very interactive, collaborative tool 00:16:37
that will be used in the very short operational planning cycle every day for MER. 00:16:41
Now, how do the scientists and engineers that are working on the MER project 00:16:47
actually get the information from the Mars rovers? 00:16:51
It's actually quite a complex process. 00:16:54
The rovers are on Mars and have their storage of data and then radio links, 00:16:57
and those radio links go up to orbiters that are in orbit in Mars 00:17:03
and also, in some cases, direct to the large antennas in the deep space network down on Earth. 00:17:08
In any case, all of the data comes down to the deep state space network 00:17:14
and then over a network is sent to the operations center in the data center at JPL 00:17:19
and finally into databases and files that store the data 00:17:24
and can be accessed with the kind of tools that we talk about. 00:17:29
So it's quite a complex process. 00:17:32
On a daily basis, the scientists and engineers have to retrieve this data, 00:17:34
assess it scientifically, engineering-wise, 00:17:41
and then again plan the next set of commands and sequences for the rover 00:17:45
and take into account what kind of transmission capability they'll have 00:17:51
as, in fact, to get data back again from the rover. 00:17:56
So they have to take all of these factors into account in their daily operation. 00:17:59
Sounds like the scientists and engineers are in a time crunch. 00:18:03
Yeah, they're in a time crunch. 00:18:06
They literally have several hours every day to go through this process. 00:18:07
Music 00:18:12
What is space transportation going to be like 10 years from now? 00:18:18
What would you like to see being done in space in the next 10 years? 00:18:21
How does math play a key role in your research? 00:18:24
When do you think we'll be going to Mars? 00:18:27
Hi, my name is Steve Cook. 00:18:29
I'm the deputy manager of the Advanced Space Transportation Program 00:18:31
at NASA's Marshall Space Flight Center. 00:18:34
We're responsible for developing the next generations of reusable space transportation systems 00:18:36
to make it much more safe, affordable, and routine to get to space, 00:18:40
along with getting in space much faster between Earth and the outer planets and beyond. 00:18:44
Math is critical to the future of space transportation. 00:18:50
We use math every day in developing new trajectories that'll take us to orbit. 00:18:53
We use it in developing new propulsion systems and computational fluid dynamics. 00:18:57
From research to test, math factors into everything we do. 00:19:01
Ten years from now, we envision that we'll have much safer access to space 00:19:06
through our second generation reusable launch vehicle. 00:19:11
As we look to space propulsion, we've got some exciting things that are going on. 00:19:14
We look to being able to move faster between Earth and the outer planets 00:19:18
through advanced electric propulsion, through advanced vision technologies, 00:19:22
and within Earth's orbit with advanced tether technologies 10 years from now. 00:19:26
We're developing the building blocks for you, the next generation of space explorers. 00:19:30
I'm with Dr. Joel Levine. 00:19:43
Dr. Levine works at the NASA Langley Research Center in Hampton, Virginia. 00:19:45
Dr. Levine, what kind of a plane is this? 00:19:49
Jennifer, this is an airplane that we hope one day will fly through the atmosphere of Mars 00:19:52
to study the atmosphere, the surface, and the interior of the red planet. 00:19:57
Wow. I mean, the plane will be exactly like this? 00:20:01
Actually, this is half scale, so the real airplane will be twice the size. 00:20:04
Dr. Levine, exactly how will this plane survey the entire planet of Mars? 00:20:08
Well, it won't survey the whole entire planet of Mars, Jennifer. 00:20:13
It will fly regional scale distances. 00:20:16
It will fly about a mile above the surface of Mars. 00:20:19
It will measure gases in the atmosphere. 00:20:22
It will measure the composition and mineralogy of the surface. 00:20:25
It will take photographs of the surface, and it will measure the magnetic field in the surface of Mars. 00:20:28
Will this vehicle be manned? 00:20:34
This is a robotic mission. 00:20:36
The whole mission will be preprogrammed by an onboard computer, 00:20:38
and it will determine the whole sequence of events. 00:20:41
Now, tell me a little bit about mathematics. 00:20:44
I mean, do you think mathematics plays a key role in having a plane such as this one survey Mars? 00:20:46
Yes, Jennifer. In fact, mathematics is very important, 00:20:52
because mathematics determines where we send the plane into Mars, 00:20:55
how the orbit is determined, and where the airplane will fly. 00:21:00
The trajectory of the spacecraft to Mars is based on celestial mechanics, which is all mathematics. 00:21:04
And the area on Mars where the plane will fly is all determined by mathematics. 00:21:10
Mathematics is very important to get the airplane to Mars, 00:21:15
and then once in the vicinity of Mars to fly through the atmosphere. 00:21:20
What is the time frame for having this plane survey Mars? 00:21:24
We think we can launch in 2007, 00:21:27
and about eight or nine months later fly through the atmosphere of Mars, 2008. 00:21:31
And interestingly, just about a hundred years after the first flight of a powered plane on Earth, 00:21:36
the Wright brothers. 00:21:43
This will be a very exciting way to commemorate this very historic event in human history. 00:21:46
All right, so let's go beyond 2008. 00:21:52
What do you think is the future of space exploration? 00:21:54
Well, up to now we've put orbiters around planets, 00:21:57
we've put landers on the surface and rovers on the surface, 00:22:00
and now we're talking about a brand new technology, 00:22:03
the use of airplanes for scientific exploration, 00:22:06
to do things that you can't do from orbit, 00:22:09
and to do things that you can't do from the surface. 00:22:11
We believe airplanes are the scientific platform of the future 00:22:14
to explore planets that have atmospheres. 00:22:17
At World Space Congress 2002, not only are there tons of exhibits, 00:22:22
but there are lots of students and young professionals here. 00:22:26
I'm here with a group of students called the Space Generation Advisory Council, 00:22:29
and we're going to talk to them and find out exactly what they do. 00:22:34
This is Shane. Shane, tell me about this program. 00:22:37
Thanks, Jennifer. I'm with the Space Generation Advisory Council. 00:22:41
We represent the world's use on various types of space activities. 00:22:44
We also work on many different projects throughout the world. 00:22:47
Two of them include a bus trip across Africa to teach African youth about space. 00:22:50
The second project we do is to distribute telescopes to inner-city youth across the United States. 00:22:55
This past weekend, the Space Generation Advisory Council held the Space Generation Summit, 00:23:00
where we gathered over 200 young people from 47 countries around the world 00:23:04
to come up with a vision on the future of space exploration. 00:23:09
These people came up with projects, ideas, so that we can get into space now. 00:23:12
Coming to the Space Generation Summit has been a fantastic opportunity for me 00:23:16
because I get together with people my own age who are as enthusiastic about space as I am. 00:23:20
Together we've put together some plans on how we're going to get to space, 00:23:24
and one of them includes developing a center to work on space propulsion. 00:23:27
I believe that space travel should be as easy as catching a bus, 00:23:31
and together we're going to make that happen. 00:23:34
During the Space Generation Summit, we shared the definition of ethics and human rights in outer space activities, 00:23:36
and we found out how to protect the space environment for all of us, including space generation, 00:23:42
next space generation, and in currently developing countries. 00:23:47
Well, at Space Generation Summit, my working group focused on space to enhance life on Earth. 00:23:51
And basically, the main topic was to use mobile and satellite communication 00:23:58
in terms of disaster management and emergency relief in developed nations 00:24:04
to use the available information that is provided through the satellites and NASA and ESA. 00:24:10
We believe that every child all around the world should be educated about space. 00:24:17
You know, I haven't seen Bianca in quite a while. 00:24:25
I wonder what's going on at the TV tournament. 00:24:27
Hi, Jennifer. I'm here with 30 kids from the Houston Independent School District in Houston, Texas, 00:24:30
taking part in the TV math tournament in cooperation with NASA. 00:24:35
The game is called Space TV. 00:24:38
It's an exciting math-based strategy and critical thinking game 00:24:40
that will enhance students' basic math skills of addition, subtraction, multiplication, and division 00:24:43
by using decimals, fractions, percentages, integers, square roots, and exponents. 00:24:49
The list of materials you'll need for this activity can be downloaded from the NASA Connect website. 00:24:57
Organize students into groups of two. 00:25:02
Distribute a game board and the necessary materials for each group. 00:25:05
Each player selects a tivet color piece or movable playing piece. 00:25:09
The white tivet player moves first. 00:25:13
The gray tivet player gets the last move if a legal move is available. 00:25:15
There are four legal moves. 00:25:19
You can move forward one diagonal space, jump over one tivet, 00:25:21
jump two or more tivets of either color in one turn. 00:25:26
To do that, there must be an empty goal between jump tivets. 00:25:30
And you can move on to or jump through a black hole goal. 00:25:33
Remember, you cannot move a tivet piece sideways. 00:25:37
You cannot move into or jump through your opponent's seven exclusive score goals. 00:25:41
You cannot move into or jump through your opponent's home base. 00:25:46
Or you can't jump over a vacant goal. 00:25:50
Choose a game sheet that you want to play. 00:25:53
There are different game sheets to choose from depending on what basic math skill you want to address. 00:25:56
Choose a tivet symbol and numbers you want to use with the game sheet chosen. 00:26:01
For example, use the tivet sets for answers without remainders. 00:26:05
Using these tivets may have answers with remainders, or you can play with the whole number rounding. 00:26:10
The game is over when one player captures all seven exclusive score goals 00:26:16
and the two common score goals are captured, or when neither player has a forward legal move. 00:26:20
Students will then fill out the score sheet. 00:26:25
Make sure you double check your answers, because once the score sheets have been filled out, 00:26:28
students will exchange score sheets and check each other's work. 00:26:32
For advanced playing, using the force jump, blocking, or trapping, 00:26:35
check out the educator's guide, which can be downloaded from the NASA Connect website. 00:26:39
So what do you think of this really cool math game? 00:26:44
I like it because it makes you think a lot, 00:26:46
and you have to position the players exactly where you want to put the players on the board. 00:26:48
I like this math game a lot because it's the beginning of the year. 00:26:53
I didn't understand fractions and decimals, and our math teacher introduced it to us. 00:26:56
I really like it. It's really fun. 00:27:02
Well, Jennifer, I can tell you these kids had a great time playing this game. 00:27:04
Back to you. 00:27:08
Well, that wraps up another episode of NASA Connect. 00:27:09

And where do you think space exploration will be in the next ten years? 00:27:39
How this? This? 00:27:50
And NASA is the core of Japanese space… 00:27:52
I'm working at the Swedish Space Corporation. It's a company from Sweden. 00:27:56
We are the… 00:28:01
How do you think space reach… 00:28:04
Now, they're on the ground. I mean, why would we want to bring them up to Earth? 00:28:10
You want me to do it? 00:28:18
When do you think we'll be going home? 00:28:20
