Welcome Back to Our Daily World Space Week Series!
Yesterday, we explored the beginnings of the Space Age, from Sputnik 1 to the Apollo missions of the 1960s – the missions that inspired our name.
Today, we are asking a big question: what does “living in space” really mean?
It is not just about floating around in zero gravity. Living in space means designing the habitats, technology and systems that allow humans to survive, work and thrive beyond Earth.
The Science of Survival: How Humans Live in Space
Humans were not born to live in space. Our bodies rely on gravity, oxygen and Earth’s natural environment. So how do astronauts survive for months aboard the International Space Station (ISS)?
They rely on:
- Life Support Systems: Providing breathable air, clean water and a safe temperature.
- Food and Nutrition: Pre-packaged meals, hydroponic plants and experiments in growing food in microgravity.
- Exercise: Counteracting muscle and bone loss caused by microgravity.
- Radiation Protection: Shielding from cosmic rays that can be harmful over time.
Every system must work perfectly, because in space, there is no “next door” for help.
Beyond the ISS: Moon and Mars Habitats
Living in low Earth orbit is one thing, but what about building homes on the Moon or Mars? Scientists and engineers are already designing:
- Lunar Bases: Using lunar regolith (Moon soil) for building materials, shielding against radiation.
- Mars Habitats: Closed-loop systems that recycle air, water and waste.
- O’Neill Cylinders and Space Stations: Large, rotating space habitats that simulate gravity using centrifugal force.
Each environment presents unique challenges, from extreme temperatures to dust storms on Mars, but solving these problems teaches us new science and engineering skills that can benefit life on Earth.
The Role of STEM in Space Living
Living in space is not science fiction; it is a STEM challenge in action. Physics, chemistry, biology, engineering and mathematics all work together to make human spaceflight possible.
“When students study STEM, they are learning the tools we need to survive and thrive in new worlds. Living in space may seem futuristic, but it is really about problem-solving, creativity and teamwork, the same skills that every student can use to change the world.”

From designing life-support systems to calculating rocket trajectories, STEM education is the foundation for the future of space living.
Fun Facts About Living in Space
- Astronauts exercise two hours a day to maintain muscle and bone strength.
- Plants in space grow differently due to microgravity. Astronauts are learning how to cultivate food for long-term missions.
- Some space suits weigh over 280 kg on Earth, but in microgravity, they are manageable.
- Water on the ISS is recycled up to 90%. Even urine is filtered and purified for reuse!
Student Challenge: Design Your Own Space Home
Here is your challenge for today:
- Imagine you are building a home on Mars or the Moon.
- Make a list of what you would need to survive, including food, air, water, energy and safety.
- Draw a simple sketch or diagram of your habitat.
Share your designs with #WorldSpaceWeek and #ApolloScholars. The most creative ideas might be featured in our Week in Review blog on 10 October!
Why Understanding Space Living Matters
Learning how humans can live in space is not just about astronauts. It is about:
- Developing technologies that improve life on Earth (like water recycling, solar energy and health monitoring).
- Inspiring students to think creatively and solve complex problems.
- Preparing for a future where humans may explore Mars, the Moon, or even beyond.
Every challenge in space teaches us how to live smarter, safer and more sustainably on our own planet.
Final Thought: The Universe Is Our Classroom
Space is the ultimate learning lab, a place where science, teamwork and imagination come together.
As we continue World Space Week 2025, remember: living in space may seem far away, but the skills, curiosity and education that make it possible start in the classroom.
Next, we will explore the technology and innovations that make life in space possible, from 3D printing to robotics, and why students today can be the inventors of tomorrow.
