This is houston acr. How do you hear me? We have you loud and clear. Please stand by for opening remarks. Good morning, im corey alderdice, director of the arkansas school for mathematics sciences and the arts located in hot springs national park, arkansas its the start of a new year at asmsa and were honored to have the opportunity to participate in todays nasa downlink with astronauts aboard the International space station at asmsa were igniting arkansass potential. Our students curiosity knows no bounds, so lets get started with our first question. My name is karis flood and im a junior and my question is, if you could add something to the international space station. What would it be and why well theres a couple things i can think of right off the bat. One is more windows, because its really incredible looking out at our beautiful planet, we have a lot of crew members up here now, theres only a couple windows, so we kind of got to share that a little more than probably we would like. Sometimes another thing is a shower, so if you guys can figure out how to make a shower for us, we would love to have one of those up here. Hi. My name is ernum deb and im a senior. My question is: what is the most surprising physical feat that youve been able to accomplish on the space station that you couldnt do on the ground? I can tell you on the ground.

I cant even do a single backflip and right now for the first time im about to attempt a triple. So here we go and he stuck the landing that was pretty impressive hi. My name is isabella mccoy and im a junior. My question is: have you ever seen any major damage taken by the station? You know we dont see a whole lot of that. Although i looked out the window a few days ago, when i was taking pictures of something else – and i saw one of our radiators – has a big tear in it so to me thats the biggest damage that ive seen on the international space station hi. My name is caitlin valdez im, a junior. My question is: how does microgravity affect the way you sleep well from my personal experience when i first got here trying to sleep where it feels like youre falling was not comfortable, but now it feels like the most comfortable mattress you could possibly have floating in space. Is a wonderful way for me to sleep, and i expect, when i return home, to have a hard time sleeping because adjusting to home hi, my name is danielle lewitt and im in the 12th grade. And my question is: what is the hardest part of becoming an astronaut? Well, when i was trying to become an astronaut a while ago, people always told me: the hardest part is just get to the interview stage of the whole process and thats pretty true.

I think i mean if you can theres thousands and thousands of people that apply to be astronauts every time, theres a selection and if you can get in the interview group thats about the top 100 to 120 or so, and so that kind of proved to be True, but once i got in that group, then i was like wow. What am i doing with these hundred people because they were absolutely incredible people – and i felt like i didnt – have the skills to be in that group, but fortunately i got selected hi. My name is sabina jay and im a junior. My question is: what would you recommend a high school student to do in order to pursue a career at nasa thats, a fantastic question? I think you should figure out what youre really passionate about and then work really hard at doing your best at everything, the things youre, passionate about and everything else you have to do and then make little decisions like express your curiosity in nasa. Listen to lectures about it, get on the internet and research. Internship opportunities do just make lots of little decisions that might eventually involve you finding an opportunity to work at nasa, theres all kinds of jobs there hi my name is sheridan death row and im a senior, and my question for you is: how has your previous career Prepared you for life in space well mark, and i both were previous uh army officers, and i was a pilot in the army, so theres lots of skills that have transferred over.

I mean a lot of the similar things that we had, even though i was a pilot, he was an engineer officer, but just you know, learning how to work as a team learning how to work in really austere environments, not needing a lot of things to survive. Our operational experience, i think, really plays, plays well for us here at nasa, where we know how to run checklists were disciplined and we know how to be leaders, and we know how to be followers whenever the time is right. So all those traits have really carried over from the army to make us, i think, better astronauts hi. My name is natalie and im a junior. My question is: what is the most interesting experiment you have conducted or have seen conducted while on the space station? I a while about a month or two ago i got to participate in an experiment called celestial immunity. One of the nice things about the space station is, since everything is in a free fall together, you can do experiments on cells that arent in the human body. Better stimulating that there are in a body, so we were able to do experiments on donated cells and test the immune responses in in the space station hi. My name is lilia adams and im a junior. My question is: what is your favorite memory made while at the space station and why weve had a couple of recent memories that uh really stuck in my mind and thats the first about a week or maybe 10 days ago? Now we had our our first real aurora sighting up here for the whole crew, and so once we saw it out the window, we all started yelling and then we all had that memory together of watching it for about 10 to 15 minutes.

So that was pretty special. Another special memory with all of our crew together was just about. A week ago we had pizza night so um we had a cargo spacecraft that showed up last week and it actually brought pizza kits for us, which is very unusual in the in space, and we got to enjoy our own homemade pizzas together. So it was a great memory hi. My name is john bray and im a senior, and my question is what camera settings lens and filters? Do you use to take good pictures of the earth given the high speed of the space station? You know one of the big things we got to do is pay attention to the window were looking at, because the optical quality of the window makes a big difference, but i just happen to have a one of our better best cameras up here, shanes, actually, incredibly Good at aiming at things on the earth to use this camera. This is a doubler, i believe, with an 800 millimeter lens as far as settings go lately. I dont know if this really works, but my latest theory is, if i put the iso to be equal to at least as high as the camera the focal length of the lens, then that enhances my chances of being successful and then trying to im lately im Experimenting with doing a shutter priority and setting the shutter speed to one over about the length of the lens the focal length of the lens as well again, this is im still learning so thats a thats, a work in progress, trying to figure out that really really Works hi: my name is danielle lewitt and i am the 12th grade and my question is: how do you defend against space debris during the stations orbit around the earth? Well, thank goodness, we have a lot of people on the ground in the mission, control, centers and other people around the united states that are watching out for big debris, thats thats, maybe in our orbit, we dont have a lot of things in our orbit.

Actually around the 250 mile mark, thank goodness, but the pieces that are out there. We have people that are tracking those and if they say, were going to come into maybe a 200 kilometer sphere of that object. Then we have a couple things. We can do the ground controllers in houston, can actually move the space station out of the way they can work with the other control centers around the world to make sure we do that safely, and so thats been done before. If we find out about an object, pretty late in the game, then theyll theyll send us to either our spacecraft uh. In my case to this, to the spacex dragon in march case to the russian soyuz and will the shelter in place there. And if something happens then well be in our return vehicle to be able to depart and come home and stay safe and if not and its not going to be that big. A deal sometimes itll just put us in a safer part of the international space station. Hi, my name is micah brown and im a senior. My question is: what are some of the current strategies being implemented on the space station to try and diversify diets and combat many fatigue in astronauts? Gosh, i think, were being really successful in a way to answer this question. Im going to show you evidence of all some of the things weve got. Weve got thermal stabilized food.

This one is one of my favorites tropical fruit, salad, its like canned fruit in a bag im just going to let that free flow for a while. Why not, then weve got things like uh. What do i have here? I got spicy green beans. These are actually delicious theyre spicy green beans, you put in 75 milliliters of hot water. Let it sit for five to ten minutes, and you got some really good spicy green beans, not everything in these packages is rehydratable. This is uh dried, its dried pears, also very good thanks for the support and then mango salad, not everything has fruit in it, but it sure tastes good when it does this ones, a mango salad, again, its rehydratable 50 milliliters of cold water, not hot water, although We dont get cold water, we really get ambient water, we do have a refrigerator, we can put things in and then this is an example of a drink bag. One of my favorites is orange juice, so we add 250 milliliters of ambient water to this and uh wait a while, let it dissolve and you get some orange juice that you can drink out of a straw. Thanks for the question hi, my name is nasha and im a sophomore. My question is: are you allowed to bring personal items with you to space? We are allowed to bring personal items. We have a little bag, its a little suitcase looking thing. Maybe about this big im showing you that we can bring personal items, and so that can range from anything from t shirts from maybe a university.

You went to to little things from your families to pictures. Um, you name it. You can pretty much put most things in there and uh. We all pretty much fill that up, because we want to kind of return special favors to to organizations that we belong to or bring up something special for our family and friends. My name is alan dodd. Im a teacher. My question is what kinds of sustainability related or environmentally focused experiments? Are you running up there that may inform our understanding of systems here on earth? Well, one of them is water. Recycling we recycle, like i remember correctly – about 95 percent, maybe were getting up to 98 of our water resources on board the station, and you can imagine all the varieties of water we have on the space station and then also uh like, for example. Today, one of the ways we support the earth is sometimes with just photography, doing: uh crew observations of the earth, theres flooding that weve been taking pictures of, and also fires, weve been taking pictures of lately to help people understand the situations on the ground hi. My name is sean and im a senior. My question is what kind of vibration isolation systems are employed to avoid movement inside the station from affecting its orbit around the earth? Thanks for the question, sean, the ones that are most familiar to me are the ones that are on our exercise equipment. So we have a resistant machine where we do our weightlifting so to speak, and then we have a treadmill and a bike that we do.

Our cardio on and all those systems are pretty much floating theyre on isolation systems, because you can just imagine if we were doing if mark here was doing a 400 pound squat and it was actually bolted to the structure. It would definitely um cause some vertebrations in in the and vibrations in the solar arrays out on the end, so we dont want to do that. We dont want to put any extra force into the structure of the space stations, and so those kind of things are on isolation systems to protect the integrity of the space station. Hello. My name is patricia mccracker valdivia and i am a genetics teacher and my question is if there are any polymerase chain reaction or pcr tests that are continuing to be done on the station right now to see how replication and repair of dna are affected by weightlessness. So we have a continuing program im, not sure if in the moment were actually actively doing it right now, but i know genes in space is a continuing program where high school students can provide inputs into experiments. We do on the space station and ive seen some incredible presentations by really remarkable students telling me what they learned also were in our fifth year of doing uh genes in space genetic research in space, so its a very promising field up here. My name is eric. Aravette, i am a student success coordinator and my question is: does weightlessness affect animal behavior? So a lot of researchers are interested in that and uh, and so we get to see sometimes very small organisms up to some kind.

Some types of animals, sometimes because of their biology, their biology, simulates, human biology and so thats. What the researchers want to see and maybe learn something from those kind of organisms and other small creatures that we can relate to humans and protect our safety down the road. So weve had a few of those on board this time on this mission, and i think on my last mission, i had several as well and mark probably did too so another ongoing investigation thing where were looking at small animals or organisms that can relate to humans. Hi, my name is nasha and im a sophomore. My question is: do you have better wi fi in space than you do at home? Fortunately, for me, when im at home, i have better wi fi there. Wi fi is quite good up here now compared to my last flight. As far as my ability to get to the same internet resources that you have available on the ground, we have a very, very uh supportive uh system up here for that. But we have a completely separate system for all the science were using and that works very well as well hello. My name is dana hughes and i am an alumna of the school. I also work in admissions and my question is: how do fluids that are thicker than water behave in space? Well, thats. Something were really interested in for a couple applications. One is fuel, so if you imagine fuel like our fuel tanks on our spacecraft, if those thing, if the fuel is sloshing around and maybe not hitting the fuel pump head, it could possibly cavitate.

So we want to understand how that behaves and weve been working on this for a couple years. Now not we but scientists and researchers weve got to do some of the experiments to help out with that, to make sure that we can understand how fuels operate, to make sure we get fuel every time we need to fire our jets. Maybe, as a spacecraft is approaching the space station, for example, another thing weve been doing and we have done on this mission – is plant. Water management is a nice experiment. Weve been working on where were looking at the flow of something a little thicker than water. In our case, we use tropical punch, believe it or not, but the scientists and researchers want to see different hydroponic techniques of watering plants and thats going to help us as we grow plants on the international space station or in space in general, and hopefully some of Those techniques can also help people on earth to our asmsa students and colleagues, as well as everyone watching online and via nasa tv thanks for joining us for todays downlink be safe, stay well, heres to a great year of learning ahead station. This is houston acr. That concludes the event. Thank you.
