What Is the International Space Station?
The International Space Station is a huge space lab that orbits the Earth. It is like a giant floating house where astronauts live and work. The ISS travels around our planet super fast—it goes around Earth once every 90 minutes! That means astronauts see 16 sunrises and 16 sunsets every day!
Hello my friends!
For a quick note, welcome to Tidbits with Titus, a podcast and newsletter where we tackle the big, curious questions kids ask every day in fun, bite-sized ways! I’m Alexander Titus, but I go by Titus. I’m a scientist, adventurer, and a huge fan of making science, technology, and life accessible to all ages. From “How does electricity work?” to “What are taxes?” and even “Why is the sky blue?” I’m here to dive into these wonder-filled questions with engaging stories and simple explanations that spark curiosity and make learning a joy. This effort is all about creating a space where families can learn together, discover the magic of the every day, and find thoughtful ways to explore the world’s big mysteries. Let’s make curiosity a family tradition—one tidbit at a time!
Just so you know, these podcast episodes are all AI-generated using Google’s really cool NotebookLM technology. That means there are some errors in how words are said, but that is part of the fun!
If your little ones have questions that you want help answering, shoot me an email at questions@tidbitswithtitus.com and I’ll see what I can do!
You can subscribe to the newsletter that has this information as well at tidbitswithtitus.com.
Also please share with anyone you think would be interested. The more the merrier!
Cheers,

How Big Is the ISS?
The ISS is very big—about the size of a football field! 🏈 It has different rooms called modules, where astronauts sleep, work, eat, and exercise. Some parts are full of scientific tools, and others are for living and relaxing.
Who Built the International Space Station?
The ISS was built by many countries working together. NASA (United States), Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada) all helped build the ISS. 🌍🤝
The first part of the ISS was launched in 1998, and astronauts have been living there since 2000. That means humans have been in space for over 20 years without a break! 🚀✨
Who Lives on the International Space Station?
The ISS is home to astronauts from around the world. Usually, 3 to 7 astronauts live there at a time. They come from different space agencies and stay for about 6 months before coming back to Earth.
What Do Astronauts Do on the ISS?
Astronauts don’t just float around all day—they have important jobs to do! 👩🚀🧑🚀
🔬 Science Experiments – Astronauts do cool experiments that help us learn more about space and how things work in microgravity (where everything floats!).
🔧 Fixing and Building – Astronauts sometimes go outside the ISS in space suits to fix things or add new parts. This is called a spacewalk! 🧑🚀✨
🏋️♂️ Exercising – Since there is no gravity, astronauts' muscles can get weak. They exercise every day to stay strong!
🍽️ Eating – Astronauts eat special space food that won’t float away. They use Velcro and magnets to keep their food and drinks from floating!
💤 Sleeping – Astronauts sleep in small sleeping bags that are attached to the walls so they don’t float around! 🛏️😴
How Do Astronauts Eat, Drink, and Go to the Bathroom in Space?
Since the ISS is floating in space, normal things like eating, drinking, and using the bathroom work differently!
🍽️ Eating in Space
Astronauts eat special freeze-dried or vacuum-sealed food. They add water to dry foods like mac and cheese. They drink from pouches with straws so their drinks don’t float away! 🚀🥤
🚽 Using the Space Toilet
Going to the bathroom in space is tricky! Instead of flushing, space toilets use air suction to pull waste into containers. Astronauts have to strap themselves in so they don’t float away! 😆🚀
🚿 Showering in Space
There are no showers on the ISS! Astronauts use wet wipes and rinse-free shampoo to clean themselves.
What Does the ISS Do?
The ISS is a big science lab in space. Scientists use it to:
🔬 Study how space affects the human body 🧑🚀
🌱 Grow plants in space 🌿
🔭 Look at Earth and the stars from space ✨
🚀 Test new technology for future space travel
The ISS helps us learn more about space and prepare for missions to the Moon and Mars!
How Do Astronauts Get to the ISS?
Astronauts travel to the ISS in rockets! 🚀 In the past, they used space shuttles or Russian Soyuz rockets. Now, astronauts also fly in SpaceX Crew Dragon capsules.
A rocket launch is very fast—it only takes about 6-8 hours to reach the ISS! 🏎️🚀
When astronauts finish their mission, they return to Earth in a capsule that parachutes into the ocean or land!
Fun Facts About the ISS!
✨ The ISS is the largest human-made object in space!
🚀 It moves at 17,500 miles per hour (28,000 km/h)—that’s faster than a jet plane!
🌍 The ISS travels around Earth 16 times a day!
🧑🚀 More than 250 astronauts from 19 countries have visited the ISS!
💦 The ISS recycles pee into drinking water—yep, astronauts drink purified urine! 😲
What Will Happen to the ISS in the Future?
The ISS has been in space for over 25 years! Scientists are working on new space stations for the future, like:
🌕 A space station orbiting the Moon
🛸 Private space stations where tourists can visit space!
🚀 Plans for humans to live on Mars one day!
Even when the ISS is no longer used, all the science and discoveries from it will help humans explore space even more!
A Quick Recap!
✔ The International Space Station (ISS) is a giant space lab that orbits Earth.
✔ It was built by many countries working together.
✔ Astronauts live and work there, doing science experiments, spacewalks, and exercise.
✔ The ISS moves super fast and goes around Earth 16 times a day!
✔ The ISS helps us prepare for future space travel to the Moon and Mars!
The ISS is one of the coolest things humans have ever built! Would you like to be an astronaut and live in space one day? 🚀✨
