Could astronauts really chow down on asteroids? Absolutely! Well, not exactly munching on the rocks themselves, but researchers are exploring the tantalizing possibility of turning these celestial bodies' contents—especially the organic materials they harbor—into actual food for future space expeditions.
This radical idea is being investigated by scientists from Western University’s Institute for Earth and Space Exploration. While we currently depend on cargo resupply missions from Earth for sustenance aboard the International Space Station (ISS), such logistics wouldn’t work for long-haul missions to places like Mars or beyond. That’s where asteroids come in. These rocky remnants from the solar system’s formation are rich not just in minerals but also contain the carbon and organic compounds needed for life.
The scientists propose using these organic components found within carbonaceous chondrite asteroids class, with Bennu being the poster child. The insights from NASA’s recent OSIRIS-REx mission to Bennu, which returned samples to Earth, have only fueled the researchers' ambitions. Asteroids like Bennu are treasure troves with 10.5% water content and significant organic material—perfect candidates for food production.
Imagine using high-heat processes like pyrolysis to extract hydrocarbons from the asteroids. Sounds simple? It involves breaking down their organic compounds to produce hydrocarbons—which can then serve as nutrients for microbes. These microbes, cultivated effectively, could generate biomass filled with the nutrients needed to feed hungry astronauts. It’s noteworthy how this concept parallels existing scientific research on recycling plastic using bacterial processes. Who knew bacteria had such culinary potential?
The Numbers Behind the Concept
Let’s crunch some numbers: the researchers estimate the edible biomass yield from asteroids like Bennu could range from 50 to 6,550 metric tons—yes, tons! That’s enough to sustain one astronaut for about 600 years. Surprising, right? It would take between 5,500 and 175,000 tons of asteroid material annually to feed one astronaut for a year.
The study suggests the extractable biomass from Bennu alone could provide between 580 million and 15.8 billion calories. Just think about it—if this idea pans out, it could lead to sustainable food sources for long-duration missions. According to the researchers, “The mass of edible biomass extractable from asteroid Bennu ranges from 1.391 × 10⁹ g to 6.556 × 10⁹ g.”
What Needs to Happen Next?
The transition from space rock to scrumptious snacks isn’t going to happen overnight. Sure, the preliminary results look promising, but researchers are quick to note there’s still much to figure out before this can be implemented on actual space missions. They state, “Based on these results, this approach of using carbon in asteroids to provide a distributed food source for humans appears promising, but there are substantial areas of future work.”
Current strategies for feeding astronauts haven’t evolved much from freeze-dried meals or small onboard gardens. While those work decently for short missions, upcoming long space voyages will demand more innovative solutions. The beauty of asteroid mining is its potential to allow astronauts to produce food on-demand, drastically reducing the need for slew of cargo trips from Earth, all the money-saving contraptions, right?
Simultaneously, researchers are testing some early phases of space foods on small animals—think worms and rats. They’ve even tried to create yogurt-like products during these test runs. While there’s clearly room for fine-tuning and improvement, the concept of turning asteroid materials directly from space to sustenance shows enormous potential.
While some might brush this off as science fiction, scientists are serious about the future of food generation during space travel and believe they’ve only skimmed the surface. Each asteroid mission has the potential to advance our technology and knowledge, which keeps the spark of hope alive for explorers aiming for worlds beyond.

The Bigger Picture of Space Exploration
Space missions have long been hampered by the need to transport supplies from Earth. The goal with asteroid food production isn’t just about meal prep—it’s about redefining how we support space exploration. By making use of the abundant materials available on asteroids, we can extend missions to new lengths without the burden of extra supplies.
Not only does this open up more distant targets for astronauts, but it also aligns with current sustainability goals. After all, one of the founding principles of modern exploration is making sure we can achieve more with fewer resources—how earthly!
A focus on mining asteroids for food doesn’t just change the equation for missions to Mars or the Moon; it has the potential to boost human longevity and food reliability beyond our atmosphere. The idea of sustaining life on distant worlds is intoxicative—creating self-sufficient ecosystems will be key to humanity’s plunge beyond our planet.
Conclusion: Eating Asteroids – A Cosmic Menu?
The researchers at Western University have stirred up excitement with the idea of asteroid-derived food sources. By exploring the potential of these extraterrestrial rocks to provide sustenance, they may very well pave the way for our future explorers to not only survive but thrive in the vastness of space. While this is just the start of what could be groundbreaking research, the dreams of asteroids becoming part of humanity’s dietary staples might not be as far-fetched as they once seemed. The focus now turns to the research needed to unravel the mysteries surrounding this cosmic culinary adventure.
