LIVE – David Saint-Jacques answers Saskatchewan students’ questions from space

Good morning, everyone — if I could have your attention. My name is Gillian Leach, and I am the
coordinator for Cameco Spectrum 2019. On behalf of the student organizing team I can’t express how excited we are to be here
today welcoming the Canadian Space Agency. Of course, welcome to everyone joining us
online. When I first contacted the CSA to see if they
would be interested in participating in Spectrum I knew it would be a long shot. So, you can only imagine our team’s exciting
when we learned of the opportunity to not only have a former Canadian astronaut
come to Spectrum in Saskatoon but to also be able to house this Q&A from the
International Space Station. With the first Spectrum being held in 1930, this
is the 27th tri-annual Spectrum, but the first to welcome the Canadian Space
Agency in this capacity. If you could join me in a round of applause in
welcoming the Canadian Space Agency to
Cameco Spectrum 2019. I would now like to invite Dr. Suzanne Kresta,
Dean of the College of Engineering, to say a few
words. Thank you, Gillian. Welcome, everyone. I am delighted to be here with you this morning
as we welcome the Canadian Space Agency to the University of Saskatchewan and to
Saskatoon. And as we gather here today I want to acknowledge that the University of
Saskatchewan is located on Treaty 6 territory, and homeland of the Métis. We pay our respect to the First Nations and
Métis ancestors of this place and affirm our relationship with one another as we build a path forward together. Many of our alumni and students have worked in
the Canadian Space Agency and have told us that space relies on a
multidisciplinary approach with engineers. We see mechanical engineers designing vertical
engine installers; electrical engineers maintaining the International
Space Station’s life support system, which keeps the air pressure, oxygen levels and
temperature steady; and chemical engineers finding out how pure
hydrogen can be combined with the
atmosphere’s CO2 on Mars to make water to drink, oxygen to breathe and
methane, to fuel a return voyage. These collaborations between many disciplines
in space, in agriculture, in healthcare and in
other industries ensure that Canada remains a world leader in
the development of technology and specifically in space and space research. As we wait for David to join us from space I want to take this chance to welcome some
very, very special guests today. Our very own U of Sask space team – USST for
short. Please raise your hands and waive — where is
Danno? And — excellent! Who are working on a Mars rover which regularly
competes internationally, as well as a cube satellite project that is
expected to launch into space in 2021. Doug Campbell, an alumnus of Engineering and
current — actually, recently graduated MSC
candidate. In May of 2018 Doug completed a simulated
space mission at the Mars desert research
station, and has been selected to join the two-year
scientist astronaut training program. Doug, could you please stand up? Mike Maguire is double-alumnus from U of Sask
with a Bachelor of Science and Engineering
Physics. Mike has worked internationally as a
communications systems engineer, working with companies like Vector Launch,
Orbital Sciences Corporation and SpaceX. Mike is usually wearing a hat and a scarf but he
has taken both of them off. So, I will ask him to stand up as well. Members that — we have representatives from
the University of Saskatchewan’s Institute of
Space and Atmospheric Studies, and members of the SuperDARN Research
Program, who use their Super Dual Auroral Radar Network
to study magnetic storms in the near
atmosphere. So, we want to welcome those people here
today as well. And finally, I want you all to give me a cheer. I want to particularly welcome the 13 Grade 3 to
8 classes that are here from Saskatoon area
schools. Are you ready? A big cheer from the audience.
Go! I want to hand to hand the podium back to
Gillian, now, who will get us ready for liftoff. Thank you, Dean Kresta. It is now my absolute
pleasure to introduce to you Dr. Dave Williams. Dr. Williams is a Canadian physician, public
speaker, CEO , author and retired astronaut. After graduating from McGill University with a
Bachelor of Science and Biology, obtaining a Masters in the Physiology
Department, A Doctorate of Medicine and a Masters of Surgery from the Faculty of
Medicine, Dave was selected to join the International class
of NASA mission specialist astronaut
candidates. In 1998 Dave Williams participated in his first
mission on STS-90, as a mission specialist 3, aboard the Space
Shuttle Columbia. During the 16-day flight Columbia orbited Earth
253 times, covered over 10 million kilometres and spent
over 381 hours in space. In October of 2001 he became an aquanaut
through his participation in a joint NASA/NOAA
NEEMO 1 Mission. During this seven-day exercise Williams
became the first Canadian to have lived and
worked in space and in the ocean. In 2006 he took lead of NEEMO 9, as crew
commander. In 2007 he was a mission specialist on
STS-118, where he took part in three or four
space walks, the highest number of space walks performed on
a single mission. He spent 17 hours and 47 minutes outside, which is a Canadian record. Travelling eight and
a half million kilometres in space, the STS-118 mission was completed in just
under 13 days. Since retiring from active astronaut status, Dr.
Williams has also authored and co-authored
several books, including: Defying Limits: Lessons from the
Edge of the Universe, and children’s titles,
including: Go for Liftoff! How to Train Like an Astronaut, and: To Burp or
Not to Burp, a Guide to your Body in Space. Please join me in welcoming Dr. Dave Williams. Well, thanks very much, Gillian. I am absolutely
thrilled to be here this morning, and we are very, very excited to be able to be
here, and then to be able to ask questions of
David Saint-Jacques, when he is in space. I like to describe myself as
just a curious kid from Saskatoon that had a chance to get into a space suit and
go out and do a number of space walks. And of course, when you are in space there is
no up and there is no down – and you can read all about that in To Burp or not
to Burp – but it is an amazing opportunity to be
able to stand on the end of the Canadarm and actually use this Canadian-built technology
to build the International Space Station. We could not have built the Space Station if it
weren’t for the Canadarm, and on my second space walk I had the chance
to ride on the end of the Canadarm and I am
holding onto a gyroscope that weighs 660 kilograms. So, imagine you are on a hockey rink and you
grab the Zamboni, and you swing the Zamboni around; that’s what
it’s like when you’re moving this gyroscope
along. And I was doing a space walk. The Canadian
flag is on my left shoulder. You can’t actually see it from the direction of
this photograph, but of course we had the
Canadian logo on the Canadarm itself. There are more Canadian logos in space than
any other country. So, I come back inside, after the mission; one of
the crew members floats over and says: Dave, we just want you to understanding that
we, in the International community, truly
recognize the Space Station as just a base for the Canadarm. It was a
fantastic moment. But, you know, looking at the Earth from such a
unique perspective is incredible, and you see this beautiful blue oasis of our
planet cast against the black infinite void of
space — this picture was taken during that first space
walk on STS-118, where we did a very famous handoff using the
Canadarm on the Space Shuttle to reach into the payload bay of the Space
Shuttle and grabbed S-5, the fifth Starbird element of the Space Station,
bring it out, hand it off to the Canadarm on the
Space Station, and then Rick Mastracchio and I were actually
working at that time on S-4 to be able to install that fifth Starbird module on
the Space Station. It was truly a remarkable opportunity for us in Canada to appreciate the importance of
the robotic contribution that we have made
in Canada to the international program. The International Space Station is a wold-class
orbiting laboratory. Right now, David is working onboard the Space
Station with his other crew mates doing research experiments that help us
understand how the body is adapting to working
in space, how we can do experiments in this unique
microgravity environment, to be able to go forward and send humans
farther into space and keep humans longer in
space. In fact, one of the things that I think is really
incredible about space research is for each of you to challenge yourselves to get
rid of the word ‘impossible’. I actually think we should take two letters out of
the word ‘impossible’ – get rid of the ‘i-m’ and to make the impossible possible. When I was a student at McGill University – that
was back in the last Millennium, by the way – in 1971, I was told that it is impossible to map
the human genome. We have done that. In biology we have mapped the genome, and
now we’re doing genomic research on board the
International Space Station. So, we are really excited that Canada played a
major role in building the Space Station and we are so excited to see David Saint-
Jacques on a long-duration mission on board the
International Space Station, using that research capability of the Space
Station to help us further understand how
humans can live and work in space. So, we are going to be speaking to David on
board the Station. At this point David is kind of
floating over, making sure that the cameras are all positioned
well, making sure that we have got the audio
setup to be able to do the downlink. And when I was on board the Space Station,
the last time I was in space, we actually did an event with students in La
Ronge, Saskatchewan. That was a lot of fun. So, it is very similar to the
event that we’re doing today, and we had a change to answer all sorts of
questions from the students. And these are one of the highlights of the day as
an astronaut, because of course, we get a chance to share our passion for space
exploration, what it is like, living and working in
space, with all of you, and be able to answer the
questions that you have, and of course, as you know, you have got some really great
questions that we are looking forward to the
answer on. So, we are pretty excited. Within a minute we’re
going to be joining the International Space
Station. We are going to start off — hopefully we will get
an image of Mission Control in Houston, that is going to come up. Mission Control
reaches out to David on board the International
Space Station. They establish the audio link and then they are
going to hand it over to us. So, there’s our image of Mission Control. Great
team working at Mission Control. They are, of course, there 24/7. We’ve got a
Mission Control in Moscow as well. So, in space we are supported by a huge team
of individuals working to support us, here, on
Earth. Right now, they are in the process of setting up
the audio link with David and it’s going to be pretty exciting, because we
have positioned the camera —
and my understanding is we are doing this from the Kibo module, on board the International
Space Station. Station, this is Houston. Are you
ready for the event? When I was there we didn’t have a Kibo module. Houston, this is Station. I am ready. University of Saskatchewan, this is Mission
Control, Houston. Please call Station for a voice
check. Station, this is Dave Williams at the University
of Saskatchewan. How do you copy? Hey, Dave! Loud and clear! I copy you loud and clear as well. It is great to
see you in space. You’re looking fantastic. I was watching the
launch; absolutely spectacular launch, and I love the grin that you had when you
opened the hatch and you came across. What is the best thing about being on board the
Space Station? It was quite a ride. I mean, you have been
through a few of these yourself, but after all these years of training — it felt
strangely familiar, because of all of the training, but of course, there, the acceleration and then
the release of tension when you reach orbit, and that first view out of the window, that is a
moment I will never forget. Well, it is absolutely fantastic. We, of course,
are very proud of you. We are proud of the great work that you are
doing on board the Space Station, and we have a whole group of really excited
students who have got great questions that they
want to ask you this morning. I will be very happy to answer their questions. So, maybe we will start off and we will have the
first student ask you a question. Hi. My name is Sophie and my question for you
is: What is it like to blast off into space? Hi, Sophie. That is the first question to ask, of
course. A rocket ride is an unbelievable
moment. After all this training you walk to the launchpad
and — I remember a comment that actually Dave
Williams made when I was in training. He said: You know, you will realize, when you
walk toward the rocket; everybody is walking away, because it is like a
giant potential bomb, but you are walking to the rocket, up the rocket.
You get into your little seat. You are all strapped in, all focused on the
displays in front of you. And when this thing starts to — when they ignite
the engines and this thing comes alive, and it is as if two giant hands were carrying you
all the way up to space, and after about 10 minutes of this vibration and
engines cutting off and new engines starting off, you get through thrown forward in your seat at
every transition; eventually, they cut off the engines and there
you are, floating in the vacuum of space. You look out the window and here is the
curvature of the Earth. My first view was of the
sunrise on Earth. It was unbelievable. Thank you. Hi. I’m Bennett and my question is: Who do you
work with on the ISS and where are they from? Hi, Bennett. So, currently we are a crew of
three. It is rare that we are so few. But our commander is a Russian, Oleg
Kononenko. He is a very experienced cosmonaut. This is his
fourth time in space. He was also the commander of our Soyuz, the
spacecraft. My colleague, here, from the U.S. is Anne
McClain. She is a seasoned military helicopter pilot and
also a professional Rugby player. She is an amazing person to work with. And the three of us, we keep the Station running
and it is a lot of work but it is also a lot of fun, and it is a great human experience of friendship
and teamwork. Thank you. My name is Jakob and my question for you is: What different roles do astronauts have to fill? Ah, yes. It is a very, very varied job, and that’s
one of things that I like about it. So, of course, you have to be basically a pilot,
because you have got to fly the rocket that
brings you here. Then, once you are here, you may have to do a
space walk. I spent a lot of time using, preparing
experiments, so being like a scientist or
technician, for — a scientist on Earth. I can be a plumber one day, a hairdresser the
other day. I can be repairing electronics. We have got to maintain the Station that is
keeping us alive. And sometimes, if we are lucky, we get to do a
space walk, go out the door – Dave Williams knows a lot about that – or use
the Canadarm, the fantastic Canadian robot that was used to
build the Space Station and that we still use
very regularly to kind of catch cargo vehicles as they come to the
Station. So, it is very, very varied. And another important role, of course, is to do
what I am doing today, which is to tell the story of space exploration
and to answer your questions. So, it is a very, very varied job, and that’s what I
love about it. Thank you. My name is Shreya. My question is: Is it warmer, in space, than it is on Earth? Hey, Shreya. So, right now I am inside the Space Station. The temperature is very comfortable. As you can see, I’m wearing a short-sleeved
Polo. So, inside the Space Station it is very,
very normal. Outside, in space, well, that is a difficult
question to answer. It depends if you are in the
Sun or in the shade. If you are in the Sun, it can get terribly hot. For example, if you take the Moon, that doesn’t
have an atmosphere, the side of the Moon that is in the sunlight is
several hundred-degrees hot, but the part that is in the shadow is several
degrees below zero. So, as you can tell, it really varies on the
amount of light that things receive. And that is also true for the spacecraft. The side of the spacecraft that is in the shadow
is very, very cold, but the other side, that is on — in the sun, it is
very, very hot, and that is a big puzzle for
engineers, how to keep these machines working correctly
even though one side is cold and one side is
hot. Thank you. Hello. My name is Brea and my question is:
What do you have to eat, in space? Hi, Brea. Well, it is actually a bit like camping food. I brought a few, to show you. So, by camping food, I mean it can be
dehydrated. For example, this is dehydrated food. We just
add water and it becomes — in this case, chili. It becomes — in this case — this is very special
food to me because that is food that — a recipe
that my wife prepared for me. We can eat foods that come in cans, like we
have on Earth. We have a can warmer and eat
out of a can. This is a soup that is kind of in a bag, like this,
an aluminium bag. You just need to open it, warm it up, open it and
you can have your soup. The rare food we have is fresh food. Some —
every few months, when the cargo vehicle
comes, people stuff apples, oranges in it. Those, of course, are the most enjoyable pieces
of food that we have on board. This is one of the few apples left, so we are
treasuring it. So, the food is very good, very varied, here. We
can share it among different countries. Sometimes we have a Russian meal, an
American meal. I brought a lot of salmon and
maple products from Canada. So, it is very, very varied. Is there any food that you can’t have on the
Space Station? So, what we cannot have, really, is a lot of fresh
food. That is very, very rare. It only comes when there is a delivery of cargo,
so that is the rare thing that we miss, especially
fresh vegetables, I find I miss most. Hello. My name is Braxton and my question is:
If you played a game in space, what would it
be? A game we really like to play is to go to the
window – the cupola, we call it – at a random moment, with our friend, and try to
guess where we are. It’s like a test of geography. Can you recognize
countries from their shape? Can you recognize a
night, cities, from their outlines? Can you recognize mountains? Oceans? So,
this is the best game, I think, to play from out here, is to look out the
window and guess where you are. Thank you. My name is Katie, and I’m wondering: How much air is on the Space Station, and is it hard to breathe? Hi, Katie! Actually, the air here, on the Space Station, is very, very similar to the air on Earth; same temperature, as much oxygen, as much
nitrogen. It has got a little bit more carbon dioxide, which
is the product of our breathing — because on Earth, when you breathe carbon
dioxide out — you breathe oxygen in and carbon
dioxide out, that carbon dioxide that you breathe out is food
for the plants, and you have a lot of plants, a lot
of trees on Earth. Here, we don’t have much, so the carbon dioxide
is a bit higher. That’s the only difference. It’s not hard to breathe
at all. It’s very easy and very comfortable, the
air. My name is Kalam and my question is: What is
your source of energy? So, hi, Kalam. The Station is an electric space
station. We have giant solar panels and that is
our main source of energy, is the Sun, with those giant solar panels. We
have batteries, so that way we can charge the batteries, and
when we are in the shade of the Earth we use
the batteries, but it is always running on electricity. Hi. My name is Sophia. My question is: How do you sleep without floating? So, we each have a little bedroom. It’s about the
size of a telephone booth, and in there we have a sleeping bag, a very
normal sleeping bag – I brought mine. This is my sleeping bag. So, I can attach it to
the ceiling or to the wall and just go inside my
bag. But the important thing is to attach it to the wall.
You have to attach the bag to the wall before
you go in it, otherwise you will wake up in the morning and
maybe you will outside of your bedroom,
somewhere. My name is Emily and my question is: How
does it feel to know that you are floating in a
piece of metal in an endless void? That is a very scary question, is it — So, while
we are here, inside the Station, you don’t really realize that, because you don’t
see outside and it feels very normal, other than the fact that you are floating, of
course – that’s not very normal. That is your only
reminder that you are on orbit, in space. But as soon as I go to the window and I look
outside, then I am reminded of where I am, and I basically feel very lucky, very fortunate, to
be here. Very few people have this privilege. That’s why it
is important for me to share it with you, share
this experience. Thank you. Hi, Doctor Saint-Jacques. My name is Danno. I
am the President of our space team here, on
campus, and I am curious how seeing the Earth from the
Space Station has changed your perspective of
Earth and its habitants. Yes. This view is really unique, and, you know,
we all sort of know this view. We have all seen these photos of Earth seen
from space, right? We know it is a blue — a beautiful blue sphere
floating in the darkness of space. But to see it with your own eyes really has a
strong effect on me, and it has — basically, it has made me want to make the
Earth better, contribute to helping others and
helping nations work together. I think this is a beautiful aspect of the space
program is that there is all of these nations represented behind me that have worked
together to build the Station. And if you know a bit of the history, some of
these countries, a few decades ago, used to be at war with each other, but they work
together in space. So, for me, that is the main effect of seeing the
Earth from above, is to see it as one and realize that the borders are inventions, and
the fact that here we can work together as
people from different countries. I think it is a good example for our future. To me
it is very reassuring. It proves to me that humans can work together
and together we will solve all of our problems. Thank you very much. Hello. My name is Albert. My question is: If you
had a compass in space, what direction would it
point to? It is a good physics question. So, as you know,
the compasses, they orient themselves
according — along the magnetic field lines of the Earth. So, the higher you go away from Earth, the
weaker that field gets. Here, on the Space Station, we are still inside
the magnetic field effect, so a compass would roughly work still, but it
would be just a bit weaker, maybe the strength of the magnetic field. If you
go far enough — for example, if you are on the Moon, then it
doesn’t work at all anymore, because the effect of the magnetic field of the
Earth is too weak, there. So, it depends how far you are from the Earth,
but otherwise it is the same as on Earth. Thank you. Hi. My name is Daniel. Where do you get all
your water supplies in space? So, the first bunch of water that we had — it was
brought here, right? It came with the supplies – a lot of it came on
the Space Shuttles. But now, we try to recycle our water. So, we are
able to recycle about 80% of all the water that
we drink. What does that mean? That means that when I
go to the toilet and pee, we don’t throw away
that pee. That pee, we would put in a big recycling
machine and it turns it into drinking water — same with the air conditioning units; all of the
moisture that is in the air gets back into this recycling machine and that is the water that we
drink. And maybe you think that is a little bit gross,
but I will tell you what; imagine on Earth, the water you drink on Earth;
every time you have a glass of water, where
does it come from? It comes from rain, and rain is the evaporation of
oceans. And what fills the oceans? Everything, including the sewage. But Mother
Earth is this incredible recycling machine and it
can — it constantly recycles the water and the air in a
perfect recycling loop. There is no new air, no new water on Earth. It
doesn’t exist. It is all old air and old water that
the Earth has recycled for us. So, here, in space, we do the same, except we
are not as smart as Earth. We have to use a machine to recycle our water. Thank you. Hi. My name is Sam and my question for you is:
If you got to visit any planet in the Universe,
what would it be and why? Well, if I would — didn’t come from Earth I would
want to visit Earth, I think, because it is by far
the most beautiful place in the Universe. But if we have to travel somewhere else, I think
it would be very exciting to go to Mars, because
it is not too far from the Earth. It should be very interesting to see – it has a
similar history – and we would learn a lot about
the history of our solar system. So, Mars would be my destination, if I could. Thank you. Hi. My name is Penelope and to become an
astronaut you have to go through a lot of difficult
training. My question is: What was the hardest training
for you to do and why? So, basically, I thought it was all hard, because
they really push you to your limits, and you have
to learn a very broad range of skills. You have to become a pilot. You have to use a
space suit, learn how to use Canadarm. You have to learn to speak the Russian
language. You have to learn a lot about space
science, about geography, geology, biology. You have to learn how to fly rockets. So, there
are many things you have to learn. So, I think the most difficult is to juggle your
energy, decide where to put your energy so that you can reach the end, and the way we
do this is with teamwork. Astronauts really are good at helping each other,
so that together, as a group, we can reach all of these incredible goals. So,
the most difficult I found was managing my
energy, because a lot on the road, far from your family –
that’s also very difficult, to be away from your family, your children, so
much. You have to put a lot of effort in keeping
the link alive, keeping your family in a good position. So,
finding the balance, I would say, between your work, your private life,
all the aspects of your work. Finding that balance is the most difficult
challenge, and that is true of any job. Thank you. Hi. My name is Ashtyn and my question for you is: When you lose all your supplies what do you do? If you lose something on the Space Station you
just wait a little bit, and eventually you will find it
in one of the filters. There is a big recycling machine for the air and
all the air ends up through a filter, going back in
the machine. So, at the grid of the filter, that’s where you find
the things that you lose. Sometimes it takes one or two days. Thank you. Thank you. Hi. My name is Jacey. My question is: How do you wash your clothes in space?: Hi, Stacy. So — Jacey. Well, unfortunately, we don’t. We cannot wash our clothes. So, we wear them until they are too smelly and
then we throw them away. But, you know, you don’t sweat so much, here,
so — I find — I am surprised that you can wear clothes for a
very, very long time and it is still very okay. Thank you. Hello. My name is Nolan and my question is:
How do you go to the bathroom in space? Very, very important question. So, here, on Earth, how do you go to the
bathroom? How do you get rid of your pee, on
Earth? You pee into water; right? And the water catches
it, basically, and then you flush the water. We
can’t do that, here, on the Station. We cannot afford to waste water like that, and
we don’t have gravity to take the pee down. So, what we do is — imagine; it’s like peeing
inside the tube of a vacuum cleaner. You switch it on — and the flow of the air is what
catches your pee. So, that’s how we go to the bathroom is with an
air suction system. Thank you. My name is Ryley and my question is: Do you ever leave the spaceship? We can go outside. Of course we have to wear a
space suit to do that. It is a very rare, very
special moment, very special event. I have been trained for that but I did not have the
chance to do that yet. It is called a space walk. Dr. Williams, who is with you, has done this
several times, so he can tell you more about it. I hope I will get the chance to do a space walk
but it is a very, very rare and special event for an
astronaut. Thank you. Hi. My name is Ethan. I am the public relations
executive for Spectrum 2019, and my question is: What do you think is the
next great step for humans in space? I think definitely the big thing we are all looking
forward to is a trip to Mars. That is the next big dream, and that dream will
lead us forward as a species. And to achieve that dream we need to move —
we need to fix several problems in science, life support, and all these steps we will make in
reaching Mars, they will help us here, on Earth. For example, we need to get better at recycling
our resources, so we can make it to Mars. We need to be better at producing energy, so
we can make it to Mars. We need to be better at fighting cancer,
because of the risk of radiation on the way to
Mars. And we need to get better at international
relations, so that all the countries can
participate to the trip to Mars. I think these four big problems are big problems
that will help everybody on Earth, but I think it is going to take several decades
before this is possible. That means for you that the astronauts who will
go to Mars, the engineers who will build the
rockets — all of these people I think are alive already but
they are still kids. They are about your age. It
could be you. It is a dream you can have. Thank you. Hi. My name is Kaitlin and I am the
administration executive for Spectrum 2019. My question is: In your opinion what was the
most important or revolutionary invention for
space exploration? Well, I think the most important — one of the most important missions and events
that I can think of is the incredible mission of
Apollo 10 — Apollo 8 – sorry – which was the first mission to actually leave the
lower-Earth orbit, the first time that humans left
the vicinity of Earth. And they went on their spacecraft towards the
Moon, and they looped around the Moon, on the far side of the Moon, and they came back
to Earth. They didn’t land on the Moon but — so they are
not so famous as Apollo 11, for that reason, but I think what they did was the most
important, biggest step in space exploration, was to leave the vicinity of Earth and actually go
into the depth of deep space — Apollo 8. Thank you. Hello. My name is Whitney. I am the personal
executive for Spectrum 2019. My question for you is: What can you do to
become an astronaut after finishing an
engineering degree? Well, there is no — there is no recipe, Whitney. I
think the only thing you must do — I cannot totally understand why this is a dream.
This is a dream that I had too. The most important thing is to look into your
heart and find something that you really, really
love; something that you really, really want to do,
because that is the only way to have the energy
to be excellent at it. And that is the only thing that all astronauts had
in common, is that they were all excellent at
what they were doing, and they loved it, and they were very happy. So,
let that be your ambition, to be happy and excellent at what you’re doing, and the only way to do that is to find something
that you love enough that you can devote all that
energy to it. David, it’s Dave. That was the last question, and I think it was a fantastic answer, because
we have a whole group of very fantastic students here today who are
interested in becoming astronauts and who
knows, one day they might get a chance to be able to
fly in space. It was 10 years from the time we first met to you
being in space, now. What is the best part of being in space? I think the best part is the view, that incredible
view of our planet, that thin blue line of the atmosphere that
protects us from the vacuum of space; to see that glow, to imagine everybody that I
know, everybody I love, everybody that — everything that has ever been done by humans
is all on that beautiful planet. And it looks alive. The rest of space looks a little bit dead — you
know, the Moon looks like a piece of rock. The stars, they look like little lights. Space itself
is black and empty. But Earth, you can tell that Earth is gracefully
moving, breathing, alive. There are clouds,
currents, weather, storms. It is an amazing sight. It is very humbling to see
how powerful, stable, strong and beautiful she
is, down there, and it gives you a lot of respect for Earth, and it
makes you want to keep her beautiful, keep
Earth alive, and come back to Earth and contribute to
making Earth a better place. Thanks very much. Well, huge congratulations
to you and the rest of the crew. Canada is following you. You are making us so
proud, doing the incredible research that you’re
doing on board the International Space Station, doing the
Canadian science. It is really, really exciting to be able to see you
in space doing these amazing things. Keep up the fantastic work. Looking forward to
maybe chatting with you again during the
mission and again, we are all very, very proud of the great work that
you and the crew are doing. Thanks to the team at Mission Control as well,
for setting up today’s event. Thank you, Dave. Thank you for being an
inspiration to me when I was a young man and a
student, and I had this dream, and I was reading about
you and I thought: Well, maybe one day I can
do what this man is doing, and here we are, talking to you from space. It is a very nice way to close the loop. Station, this is Houston ACR. That concludes
the event. Thank you, Canadian Space Agency and
participants. Station, we are now resuming operational audio
communications. Thanks very much, Houston. All right. Huge round of applause for David and
the crew. And at this point I will hand it back over to
Gillian. Thank you, Doctor Williams. I would now like to
welcome our awesome student questionneers and the participants on the stage, for a photo
with Dr. Williams. And while they are making their way up, just a
few housekeeping items, before everyone heads
over to Cameco Spectrum 2019. So, Cameco Spectrum 2019 opens officially this
morning at 10 o’clock, and runs until Sunday at 5:00. Teachers who do
not have students, either on the stage or making
their way to the stage right now, you will be leaving first, followed by special
guests, and then teachers who do have students
on the stage – or students making their way up to the stage will
have to collect those students, and the students will only be released to the
teachers that are on the students’ nametags. So, before you all leave we have a video
presented, from the Canadian Space Agency. Thank you all for joining us this morning and I
hope to see everyone at the College of
Engineering this weekend, for Cameco Spectrum 2019. Thank you.

  1. You need to create a sophisticated device
    To detect gravitational waves of cosmic inflation
    14 billion years ago

    There are two types of gravity waves
    The first type is the waves of galaxies in the universe
    The second type is the inflation waves of the universe 14 billion years ago

    The trouble is the waves of cosmic dust
    Because the waves of dust are interfering with the waves of inflation
    For this reason there is no clear evidence of inflationary waves
    14 billion years ago
    We need to invent advanced hardware
    To distinguish between dust waves and inflation waves
