Space exploration has profoundly influenced human life and civilization. From uncovering valuable resources to driving scientific innovation and addressing existential questions, space has been a pivotal area of exploration. Our ventures into space have taught us a great deal, particularly because living there poses numerous challenges. Space presents natural hazards, mechanical issues, and the basic human needs for food, water, and air. Despite these challenges, we have become proficient at surviving in the harsh conditions of space. However, with the rise of hyperindustrialization and climate change, living sustainably on Earth is becoming increasingly difficult. Can the lessons we’ve learned from space help us live more sustainably here on Earth?
Over the past 60 years, numerous space missions have provided valuable insights into living in space. The first human in space, Yuri Gagarin, embarked on a historic flight aboard Vostok 1 in 1961, launched by the Soviet Union. His journey lasted less than two hours. Subsequent missions, such as Vostok 6 with Valentina Tereshkova, the first woman in space, lasted almost three days. The food provided was reportedly unappetizing. Years later, Apollo 11, which took Neil Armstrong to the moon, lasted just over eight days. However, the true era of living in space began with the advent of space stations. The concept of a space station—a satellite capable of supporting a human crew in Earth orbit—has existed in science fiction since the mid-19th century.
Today, the International Space Station (ISS) has been orbiting Earth since its launch in 1998. It can accommodate seven crew members for long-term missions, with supplies sent up every 40 to 45 days. NASA has developed a closed-loop system known as the Environmental Control and Life Support System, which provides clean air and water through regenerative life support hardware. Water, being essential yet heavy, is costly to transport. Until 2008, astronauts relied solely on water sent from Earth, but the ISS’s closed-loop system was upgraded to recycle wastewater. More than 90% of recaptured water is reused, sourced from moisture in the air, astronaut sweat, and even urine. Interestingly, the recycled water is often cleaner than some drinking water on Earth.
The ISS generates air using the Oxygen Generation System, which breaks down water molecules to release oxygen. This advanced closed-loop system also recycles exhaled carbon dioxide back into usable oxygen. In the early days of space exploration, food options were limited, with astronauts consuming pureed meals from aluminum tubes. Today, ISS crew members can choose from over 150 meal options. The Vegetable Production System, known as Veggie, is used to study plant growth in microgravity and provide fresh vegetables for astronauts.
On Earth, life is becoming increasingly challenging due to rapid resource consumption. For instance, our consumption of metals has increased 20-fold in the last 75 years. Scientists estimate that, at current rates, resources may begin to run out by the 2040s. Most of our energy comes from burning fossil fuels, contributing to rising CO2 levels in the atmosphere. CO2 levels have reached 416 parts per million, the highest in nearly a million years, resulting in a significant increase in global temperatures.
The construction industry is a major contributor to CO2 emissions, responsible for 38% of energy-related global emissions in 2019. To achieve net-zero emissions, construction-related CO2 emissions would need to decrease by 6% annually, but projections indicate they could double by 2050. Urbanization is rapidly increasing, with over half of the world’s population now living in urban areas. By 2050, the global population is expected to reach around 9.8 billion, with two-thirds living in cities. This rapid urbanization will require adding 2.4 trillion square feet of new building space globally by 2060.
Building cities has significant environmental impacts, with construction and demolition waste contributing to landfill issues. In the EU, 75% of this waste ends up in landfills, and in the U.S., it has tripled since the 1990s. The demand for sustainable architecture is growing, focusing on minimizing environmental impact through energy-efficient designs. The global green building materials market was valued at over $190 billion in 2021, driven by the need for energy-efficient buildings.
However, merely minimizing impact is not enough; we need regenerative architecture that actively works to reverse environmental damage. This includes designing buildings that produce and store energy on-site and implementing technologies like biodigesters that convert waste into usable energy.
Space technology is beginning to influence how we think about living and building on Earth. For example, water purification products developed for the ISS are now available on the market. Interstellar Labs is developing a self-sufficient living module called the Experimental Bioregenerative Station (EBIOS) in California’s Mojave Desert. This prototype will generate its own food and water while recycling waste. The biopod, a module for crop cultivation, aims to grow food locally, reducing transportation emissions and water consumption significantly.
These innovations offer exciting possibilities for future sustainable living, both in space and on Earth. While the adoption of regenerative technologies may be slow and costly initially, the increasing interest in sustainable living could lead to more affordable solutions over time.
Imagine you are an architect tasked with designing a sustainable home using principles and technologies inspired by space exploration. Consider elements like closed-loop water systems, energy-efficient designs, and waste recycling. Present your design in a visual format, such as a digital model or a detailed sketch, and explain how each feature contributes to sustainability.
Conduct research on regenerative architecture and its potential to reverse environmental damage. Focus on how space technology can be integrated into these designs. Prepare a presentation that highlights key innovations and case studies, discussing the challenges and benefits of implementing such technologies on Earth.
Examine the environmental impact of urbanization and the construction industry. Use data to analyze trends in resource consumption and CO2 emissions. Create a report that proposes solutions inspired by space technology to mitigate these impacts, such as using green building materials and energy-efficient designs.
Work in groups to design a prototype of a closed-loop system for a small community or building. Incorporate elements like water recycling, waste management, and energy generation. Present your prototype, explaining how it mimics systems used in space and its potential applications on Earth.
Participate in a debate on the future of sustainable living. One side will argue for the rapid adoption of space-inspired technologies, while the other will discuss the challenges and potential drawbacks. Use evidence from space missions and current sustainable practices to support your arguments.

It’s well-known that space has had a tremendous impact on human life and civilization. Whether we’re discussing valuable resources, potential for scientific innovation, or answers to significant existential questions, space has been a key area of exploration. Our experiences in space have taught us a lot, primarily because living there presents numerous challenges. There are natural dangers, mechanical issues, and, unless you’re a robot, you’ll need food, water, and air to survive. Overall, we’ve become adept at living in the harsh conditions of space. However, due to hyperindustrialization and the effects of climate change, it’s becoming increasingly difficult to live on Earth as well. Can the lessons we’ve learned from living in space with limited resources help us live more sustainably here?
Over the past 60 years and through numerous missions, we’ve gained valuable insights into what it takes to live in space. The first human in space was Yuri Gagarin aboard Vostok 1, launched by the Soviet Union in 1961. His historic flight lasted less than two hours. Later missions, like Vostok 6, which carried the first woman in space, Valentina Tereshkova, lasted almost three days. The food provided for her was reportedly quite unappetizing. Years later, Apollo 11, which took Neil Armstrong to the moon, lasted just over eight days. However, humans truly began living in space when space stations became a reality. The concept of a space station—a satellite capable of supporting a human crew in Earth orbit—has existed in science fiction since the mid-19th century.
Currently, the International Space Station (ISS) has been in low Earth orbit since its launch in 1998. It can house seven crew members for long-term missions, with supplies sent up every 40 to 45 days. NASA has developed a closed-loop system known as the Environmental Control and Life Support System, which provides clean air and water to the crew through regenerative life support hardware. Water is essential but also heavy, making it expensive to transport. Until 2008, astronauts relied solely on water sent from Earth, but the ISS’s closed-loop system was upgraded to recycle wastewater. More than 90% of recaptured water is reused, coming from moisture in the air, astronaut sweat, and even urine. NASA invested in a Russian-designed space toilet that allows crew members to relieve themselves while contributing to the station’s water supply. Surprisingly, the recycled water is often cleaner than some drinking water on Earth.
The air on the ISS is generated by the Oxygen Generation System, which breaks down water molecules to release oxygen into the station’s atmosphere. This advanced closed-loop system also recycles exhaled carbon dioxide back into usable oxygen.
