001[Music] all right boys and girls let's start quieting down the program is getting ready to start all right listen up boys uh first questions i don't we fly in a rocket ship now by raising your hands hello students at van buren elementary school this is uh governor eric holcomb joining you today what a great day to be a wildcat you may recall that indiana was the birthplace of the first person to set foot on the moon neil armstrong of course he was a graduate of indiana's purdue university up in west lafayette indiana also known as the cradle of astronauts boiler up hammer down but now you are part of another history that's being made and i know you'll never forget today i'd also like to extend a warm hoosier welcome to the crew of expedition
00267 as you enter indiana web space from space so on behalf of our state thank you for serving all of humanity and indeed our world as astronauts at the international space station do your most important job and thank you for taking the time to downlink with students here in indiana in brown county we all couldn't be more grateful for the way you continue to pioneer advancements and conduct research that could lead to improved technology and health for years to come here on the planet we all call home couldn't be more proud finally students and school staff faculty teachers everyone that had a hand in this congratulations on this opportunity that is truly out of this world your nationally recognized dedication to teaching and learning makes us proud and will continue to take you as far
003as you want to go in fact i'd go so far as to say that today proves that not even the sky is the limit for you all so learn all you can and reach for the stars you're going to catch them all of us on three one minute station this is houston are you ready for the event at the station i'm ready for the event houston acr this is mission control houston please call station for a voice check control houston please call station for a voice chair station this is houston acr how do you hear me how do you hear me houston acr i have you loud and clear how many i have you loud and clear please stand by for the first question hi my name is soyul reynolds i'm in first grade and
004why do you want to be in space hi sawyer uh thank you for the question i have dreamed of being an astronaut and wanting to fly in space for as long as i can remember i was inspired by books and uh and movies and then when i was in second grade so in the grade that many of you are in right now i remember my teacher wheeling a television into the into our classroom and seeing the very first space shuttle launch and that's when i knew that there was a path a possibility of getting finding a job of living and working in space and i'm so grateful to have this opportunity my name is reese weitzman i'm going into the fourth grade and my question for you is what are your spacesuits made of thank
005you for that uh great question um our spacesuits are absolutely amazing pieces of technology uh they have 16 layers there's a hard layer that covers the torso and then soft layers that cover the arms and legs three those first three layers provide ventilation and cooling to our bodies and then we have several layers a layer a bladder layer that keeps the the oxygen and atmosphere in there and then a restraint layer on that on top of that so that the bladder doesn't blow up like a balloon and there are several more layers there that to provide water resistance and tear resistance that protect us to help with insulation to keep us warm and and then also layers to reflect light and heat and also to protect us uh in the event that we get uh
006hit by micrometeorites something to essentially the same some of the same materials that bulletproof vests are made of so it's an amazing piece of technology and it keeps us safe when we go outside the space station hi my name is colin peck and i'm in the third grade my question is how does a spaceship launch well that's a great question we had the opportunity to launch on a in a spacex crew dragon on top of a falcon 9 booster and so anytime we're launching something to space we put uh we'll put our the the cargo in in the case of our spacecraft are there our dragon capsule on top of a big rocket full of propellant and uh it burns that propellant that gas and an oxidizer like oxygen using something like oxygen to uh
007create a basically combustion and that the the results of that combustion get accelerated through the nozzle and that's what pushes up up into space and the bigger the payload or the further it's going the more fuel and the bigger rocket you need and so i'm super excited about the artemis rocket that we're going to launch here in a few months that is establishing our return path to the moon my name is hudson bernard and i am in third grade what does launch feel like a launch launches are absolutely amazing so um you hear the countdown and we all are very familiar with that countdown three two one and then we fueled the uh the vibration of the spacecraft as the motors start to spin up and then you start to feel pr we when we're
008launching we feel a pressure like we're getting pushed back into our seats and it's kind of like if you're on a roller coaster in a car that starts to accelerate really fast you get pushed back into your seat well that's what we feel like and that goes on for about eight and a half minutes until we get into low earth orbit and then that acceleration goes away and then all of a sudden you're free-floating and you're in space it is absolutely amazing hello my name is eli summers i'm in the fourth grade how does the space station get its power yeah um it's really amazing that uh that we don't have to get power from the ground we generate all of our own power with the amazing solar arrays that we have on the outside
009of the space station and in fact we're in the process of upgrading our solar arrays so that we're going to have six brand new solar arrays that are kind of layered over top of our existing solar rays each one of those new solar rays generates about 20 kilowatts of power so all together 120 kilowatts in addition to the the solar rays the existing solar rates which produce about 95 kilowatts it's going to be a total um power generation of about 215 kilowatts provides power for all of the equipment inside for our environmental control system and uh and our ability to control the the spacecraft in space and and to have communications like this so that we're able to to share our experiences with the ground hello my name is mckenzie sattler and i'm in the
010first grade how do you get oxygen in space thank you that's a great question we need oxygen to breathe we need it on the ground in order to survive in space there is no there's no oxygen no atmosphere up here so we have to create our own atmosphere here in the space station um that means a lot of nitrogen but we humans and most living organisms need oxygen in order to to live and so initially we would bring oxygen have oxygen delivered in cargo vessels in in big tanks and that's released into the atmosphere but we are also able to generate our own oxygen we have a system called the oxygen generation system which is very uh very original but this takes water it uses electricity to split water into hydrogen and oxygen and we
011can use that oxygen then as a part of our atmosphere so that we can breathe and this is really important for future exploration when we go to the moon into mars we can't have target vehicles constantly bringing us supplies it just doesn't work so we have to be able to recycle our atmosphere recycle our water and so that oxygen generation generation system is an important part of that that that environmental control system hello my name am in fourth is how do you eat in space well this is uh one of my favorite favorite things i think our whole crew really likes to enjoy meals up here and so i'm just going to show you quickly kind of what we have available to us half of our food comes pre-cooked and then into these kind of
012metallic envelopes and so all we need to do is warm this up we put it in we have a food warmer we slide this in there has these hot plates in there this sits against that and this gets warmed up and we open it up and this is a chicken fajitas so that's pretty yummy we put that on a tortilla we have tortillas up here to eat with our food but what to drink so we have these little aluminum looking packets kind of like a capri sun if any of you've had those but what we have inside is uh is a powder and so if it's coffee it's powdered coffee if it's juice powdered juice this happens to be to be milk and and then some of our food is dehydrated so here's an example
013of a dehydrated food that we would that we would add water to and then some of my favorite things this may be familiar to you oh so as astronauts we get to play with our food and there's nobody nobody here to tell us not to thank you for the question hi my name is logan hathaway and i'm in second grade how do you guys prepare your food tell your mic is off mainly for food that's already been pre-cooked we will put it in a food warmer and that's how it will warm the food up and it gets really warm so it gets pretty tasty and we have a refrigerator too so if the food is supposed to be cold we can put water into it and then and then put it in the refrigerator to
014cool off and then some of our food will add water to it and then cut it open and we'll use a spoon so it turns out the two most important utensils here in space to eat are scissors to cut open your food packets and a spoon to dig it out hi my name is bob catrick i am in this preschool do you drink milk on the space station we can drink milk milk is an important part um it keeps our bones healthy and we certainly here in space we're concerned about our bones our skeleton and so milk is an important part of keeping us healthy just like it is keeping you healthy on the earth so this drink packet actually has milk in it i don't know if you can read that label so this
015has milk so it's powdered milk we put water into that and that reconstitutes into milk and here you can see this is oat cereal and so there's actually powdered milk down at the bottom of this in addition to the cereal and and so when we add water to this it makes milk in there that we for us to eat with our cereal pretty cool hello my name is ava katrin i am in the first grade can you listen to music on the space station we can listen to music on the space station in fact i think most of us really enjoy listening to music i like listening to music when i work out and uh and then also while i'm working i'll have some music playing in the background so we have a support team
016on the ground that sends up lists uh we'll send down a list of the music we'd like to listen to and they send it up and it's available we can access it through a web page and it works really great and it reminds us of home hi my name is phoenix dunn and i'm in kindergarten do you play games in space well we absolutely can play games in space we don't have a lot we don't have like a lot of board games up here because all the pieces would just float away we've got a pot we've got a few soft kind of spongy balls that we can throw around but we try to be really careful because the space station you know if you can kind of look around me it is just there are
017computers and equipment and people science all around and so we want to be very careful and take great care of the space station but you can see for example we've got a couple inflatable balls here this is i think maybe mercury and you can see we've got a sun and a moon behind and we'll kind of figure out fun things to do to have fun up here hello my name is ryan lucas and i'm in third grade how do you keep your muscles strong in space well that's a really good great question we talked a little bit about the bones um and we work really hard to keep our muscles strong so if we don't do any sort of exercise up here um it's kind of like you know we're up here for six months
018it would be kind of like just laying in bed for six months your muscles become weak your bones become brittle and weak your heart your cardiovascular system doesn't work as well and so we have to work out every day in fact just before this i was i was on our treadmill we work out every day to keep our hearts strong our muscles strong and our bones strong and so we have a an exercise machine because there's no gravity here to provide weight we use evacuated cylinders to provide resistance and this machine is kind of like a universal gym and we can do all sorts of exercise on it but we exercise every day for an hour on that machine and then we'll get onto either a treadmill or an exercise bike to keep to to
019get a good workout and keep our hearts healthy great question hello my name is avalon julia and i am in the third grade are there any animals on the space station avalon great question we have had and do have animals on the space station they're an important part of our research program they help us to understand um how how we and how animals uh how living beings adjust to weightlessness and the kind of changes um that we can see one animal in particular is the fruit fly and this is an animal that i studied when i was in college in a genetics class because you can have many generations of flies in a given amount of time and you can see the genetic changes you can actually see those changes expressed in different colored eyes
020different types of wings you can see that expressed over different generations and so for as an example the fruit fly is one type of animal that we've studied up here we've had spiders up here in the past to see uh what would happen how they spin different types of webs and i'd encourage you to look ask your parents to help you look online because it's very interesting some of the spiders spun very wacky webs but then over time they started to look more more normal and and so it helps to understand how animals adjust to being in this environment much like we adjust to being in this in this uh very different environment my name is lachlan steele i'm in kindergarten if you had a stake in outer space how will it sliver boy that's
021a really good question and i wish i knew the answer i'm glad that there are no snakes up here that would be that would be interesting um you know i think that they would they would try and slither like they do on the ground i think like when we get up here our first reaction to floating is to kind of like you feel like you're falling a little bit and i think snakes would try and slither i think when you look at snakes that swim in water that they might try and slither like they swim in water but i think over time you know they would adjust and as they touch something maybe they would coil around it to get some purchase on something and over time they would learn how to maybe they would
022find a handrail and stick and then they would be able to slither along the wall it's very it's a very interesting question and i'm excited that somebody's going to study that someday hello my name is bradley sarr and i'm in fourth grade how long does it take to send or receive messages from your family thanks for that question it's a that's a really important part of a long duration mission is the ability to communicate with our family and friends back home we're very fortunate that we're in low earth orbit and so it is almost instantaneous the ability to like we're doing right now to talk with the ground you can detect just a very small delay but in terms of the vastness of space we are very very close to the earth and so our
023messages either using a internet phone talking to our family and friends by phone or talking over the radio to mission control or sending video signals along that same those that same radio um it uh it happens very quickly and that's going to be a challenge when we start to venture further and further away from the earth our message will for example as we go to mars some of our messages may take up to 20 minutes to get to mars and then another 20 minutes to get back and so it may take 40 minutes to an hour for a round-trip kind of conversation and it's something that we're going to have to to adjust to as we start as we begin to explore deeper and deeper into our solar system hello my name is mcqueen and
024i'm in fourth grade how do toilets work in space well they work very well and we are all very very grateful for that when we get up to the space station it's one of the first things that we are oriented to the the the crew that's here they took us around they showed us this is where you get water and food this is uh where you will sleep and this is where you go to the bathroom those are the and then here's all the emergency equipment that those are the most important things to know when you first get to the space station uh the toilet has two parts to it and so uh hello number one there's a there's a hose much like the hose that's on your vacuum cleaner the extension hose and that
025is where the liquid waste goes it uses a vacuum there's a fan that pulls the liquid waste into that hose that liquid that urine goes to the urine processing assembly which then goes to the water processing assembly which then goes to the potable water dispenser basically our water fountain so we recycle our water um and uh and we're able to recycle up to about 96 of our water now which again is super important for these emissions going to the moon and to mars because we can't carry all that fresh water with us and that water actually work the system works really really well the solid waste goes into something that looks very much like a toilet back home there's a seat with a hole in it there's a perforated little baggie at the bottom of
026that hole and vacuum suction pulls the solid waste into that baggie and when you're done you unravel the baggie drop it into the bin below the air the suction pulls it down there and you put a new baggie in and you close up the seat so the system works great hello my name is emily tracy and i'm the superintendent of brown county schools in nashville indiana i want to extend our warmest thanks to the astronauts on board the international space station for taking this time today to educate our students in brown county schools your leadership and your experience are invaluable and we could not be more grateful thank you for all you do to advance stem education and the opportunities here on earth and for being an example of what hard work and dedication can
027look like today is certainly a great day to be a wildcat thank you so much for the opportunity to uh to to chat with you all you had great questions and i wish you all the best keep working hard and reach for the stars station this is houston acr thank you that concludes our event [Applause] thank you to all participants stationed we are now resuming operational audio communications for a little bit longer how many guys learned something new houston on tv [Music] okay the astronaut that we spoke [Music] right [Music] a thousand different times [Music] okay wildcats
