International Space Station
Welcome to bedtime history. Good evening this is and I'm super excited to share our first bonus episode. Yes this extra episode exists because fans donated to patriotic and made it possible in a shadow to our new donor this week. Abbey and Nellie from Montreal Canada. That's one donor on our way to the next ten so nine more we'll do yet another bonus episode and yes I do. Oh you guys. Another bonus episode. I haven't forgotten another way to support. The podcast is by leaving a quick review and subscribing. I love reading the kind comments and the reviews and it goes a long way to making our podcast more popular so kids all around. The world can find it too and one more thing. We released two new videos on Youtube both about George Washington. The new videos have lots of fun graphics and animations. I worked especially hard on them. See off to be sure to check them out and subscribe to our Youtube Channel now onto our episode. Close Your eyes and imagine you're floating in the air in spacecraft. You're weightless it feels so strange. She had amazing at the same time. You push off the wall and float down along room. You feel like Superman flying across empty space for fun. You Duck your head and do a quick flip before landing against the other wall and pushing off to soar the opposite direction at the end of the next room. You grab hold of something and stop to look out the round bubble window below. You see a glittering blue ocean clouds and Brown land in the distance you are two hundred miles above earth onboard the International Space Station and flying around the world at seventeen thousand miles per hour or twenty thousand kilometers per hour. Have you ever heard of the International Space Station Right now? It's circling the earth above you. It's going so fast that it orbits the Earth every ninety minutes that means fifteen and a half times a day. That's incredibly fast. Some people think the space station is floating in space. But it's actually falling around the earth. In what is known as an orbit the International Space Station also known as the ISS is special because it's not owned by a single country but by many countries who work together to build it it started off as a single module has grown piece by piece into the larger station. It is now in nineteen ninety eight. Russia launched the modules Aria into low earth orbit as the first piece low-earth orbit means. It is still within the Earth's orbit not far off in space beyond the earth strong gravitational pull two weeks after his Aria was launched the United States launched its own space shuttle with the unity module and its astronauts on board. The next step was connecting. The I two modules. The astronauts did this by floating out into space and attaching them and that is how the International Space Station began after that. The other pieces were slowly added to the ISS until it grew and grew in two thousand came. The Russian modules visit then Nastase destiny module Canada's space program contributed a robotic arm for spacewalks and to make remote control repairs the harmony module came in two thousand seven then the European Space Agency sent up the Columbus Module. Japan sent up its own module in two thousand eight next came Nasr's tranquility module then Europe's Leonardo module and finally the bigelow module sent by a private company. One reason I assess. Amazing is because it's a team effort by many countries around the world usually around three to six astronauts live and work on the ISS at a time. It was made for many reasons but one of them was to do research since humans plan to go to Mars someday. They're using the ISS to see how space will affect the astronauts during the journey to Mars for example what will spaceflight due to their bodies. What kind of foods will they need to eat? What kind of exercise will they need? Will they be able to grow plants? They've also tried out different devices. They'll need in space such as three D printers and coffee makers on the ISS. The cruise days are very busy and besides doing experiments they spend a lot of time doing maintenance which means keeping the station running smoothly. Each astronaut has a different responsibilities. Sort of like you might have doing chores at home. Only by working together will the ISS continued to work properly often the astronauts climate of their space suits and spacewalk which means to go outside the ISS and float around to make repairs. This can be dangerous work so they always attach themselves to the I assess for safety. The astronauts have also been testing robot. They can use to fly around they. I assess and make repairs for them. The other important part of an astronaut's days taking care of themselves making sure the the right foods showering brushing their teeth and getting exercise. They also do things like video chat with school children and talk about what they're doing with people around the world. They do this to get others excited about the space station and space research eating in zero. Gravity can be very tricky. Their food has to be strapped down to a table and utensils and water bottles have magnets on them to keep them from floating away. If you look on the Internet you can find some funny videos of the crew doing flips floating around and dancing and playing with water in zero gravity. Water floats around in blobs people from nineteen different countries have visited the ISS. These include the United States Russia Japan Canada Italy France Germany Belgium Brazil Denmark Kazakhstan Malaysia. The Netherlands South Africa South Korea Spain Sweden the United Arab Emirates and the United Kingdom. Now you can see why they call it. The International Space Station international means many countries at the ISS. It's exciting to see people from many countries working together. It's a perfect example of how working together people across the world can accomplish amazing things many people dream of visiting space someday and some companies promised that someday anyone who can pay for it will be able to do it right now. I can be very expensive and at times. Not even possible to visit places like the ISS but someday space vacations may be available to everyone. Can you imagine visiting a place like the ISS or a far off hotel on the moon? This is called space tourism and a few very wealthy people have been able to visit the ISS by paying for it but it costs them many millions of dollars. One of these people was on a show on sorry was born in Iran and moved to the United States. When she was little she was interested in engineering and graduated from college to become an engineer. She and her husband later started a company that grew and grew until they were very wealthy. Should always dreamed of going to space and became interested in visiting the space station when she found out they were allowing some to visit. If they paid she jumped on the chance I she trained for the journey then took a Russian rocket up to the ISS and lived and worked there for a short while there. She helped to do experiments and later wrote a book about her. Amazing Journey. One of the most well known astronauts to live on the ISS. Is Chris Hadfield? Chris was born in Ontario Canada. He grew up on a farm with his family where they grew corn. When Chris was little he became interested in flying later saw the Apollo eleven moon mission which made him want to be an astronaut. Just like Neil Armstrong later. You went to college then. Joined the Canadian Air Force. This eventually led to training is an astronaut for the Canadian Space Agency and working on the International Space Station on the ISS. Chris shared his day to day activities on twitter and facebook and later made a music video on Youtube while playing guitar in space. This brought even more attention to the important work they were doing on the ISS. Many records have been set by the crew of the ISS such as the most consecutive days in space by an American which was three hundred and forty days by astronaut. Scott Kelly the other cool thing about Scott's tripped the ISS is. He's a twin so they're able to study how space affected. Scott versus his twin brother who stayed on earth another record was the longest spaceflight by a woman at two hundred eighty nine days by Peggy Whitson the ISS also holds the record for the most people in space at once which was a crew of thirteen in the year. Two Thousand and nine. Did you know you can see the space station from Earth with the help of your parents? If you go to spot the station DOT NASA Dot Gov you can sign up to receive text messages or emails whenever the space station is visible above you. Recently my kids and I did this and it was amazing to see. It flowed across the night sky like star one of the best lessons. We can learn from the International Space Station. Is that by working together? People all over the world can do amazing things. Isn't this so much better than focusing on our differences and fighting one problem in the world is when people look at those who are different. They think there's something wrong with them because they aren't the same but differences are what keep the world and there's so much we can learn from each other from our different experiences and customs and believes the space station shows that even though we have differences we have common goals like visiting space and learning about space and the earth as we focus on. What'S COMMON? We can work together to do great things a couple years ago. I worked with a man from India. I'd never met someone from India so it was very interesting listening about his homeland. What it was like to grow up in India and has different believes he celebrated different holidays and had different ideas about the world but it fascinated me to try to see the world through his eyes as we got to know each other. We became friends and I look back. On our talks with fondness. Take a moment to think of someone you know. Who's different than you? They might be from a different country or look different or talk differently or active. Really take the leap and ask them a few questions and try to get to know them better. Because chances are you'll learn something interesting and possibly make a new friend in the process. Thanks for listening and we'll catch you next time.
