NASA is quietly betting that the future of human settlement beyond Earth will depend not only on rockets and reactors, but on crickets, mealworms, bumblebees and the chitin in their shells. Instead of treating insects as pests to be excluded from pristine space habitats, researchers are starting to treat them as core infrastructure for food, materials and waste recycling on the Moon and Mars. If that vision holds, the first truly sustainable off‑world communities may look less like sterile labs and more like compact, carefully managed ecosystems humming with tiny life.
That shift reflects a hard reality: shipping everything from Earth is impossibly expensive, and closed habitats cannot rely forever on canned food and disposable packaging. Insects offer dense nutrition, powerful ecological services and versatile biochemistry in a fraction of the mass and volume of traditional systems. I see NASA’s new interest in bugs as a sign that space exploration is finally moving from heroic expeditions toward the mundane, biological work of staying alive.
Why NASA is turning to insects for off‑world survival
NASA scientists are increasingly explicit that long‑term human presence away from Earth will require a living support system, not just life support hardware. Insects fit that requirement because they can convert waste into food, pollinate crops and provide raw materials, all inside compact, controllable modules. When NASA researchers describe looking to Earth’s smallest creatures to help build sustainable life on the Moon and Mars, they are acknowledging that the physics of launch costs and resupply windows make biological “co‑workers” a necessity rather than a novelty, especially for any base that aims to grow beyond a handful of astronauts.
In that context, the agency’s focus on insects is less a quirky side project and more a strategic bet on resilience. The same work that explores how NASA scientists can use bugs to support life on the Moon and Mars also forces mission planners to think in terms of ecosystems instead of supply chains. I see that as a profound shift in mindset: the agency is starting to design habitats where insects are not contaminants to be scrubbed out, but partners in humanity’s off‑world survival.
From rockets to ecosystems: the logic of bioregenerative design
Once you accept that permanent bases must function as ecosystems, the design challenge changes completely. Rather than asking how many tons of food and water a mission can carry, engineers begin asking how to close loops so that every output becomes an input for something else. Bioregenerative Life Support Systems, often shortened to BLSS, embody that approach by integrating plants, microbes and animals into a coordinated architecture that can recycle air, water and nutrients. Insects are a natural fit inside that framework because they can bridge gaps between inedible plant waste and edible protein, and between structural materials and the organic chemistry needed to make them.
NASA’s own technical work on Linking Nontraditional Food Sources with BLSS Design makes the logic explicit: a large portion of plant biomass grown in a closed system is inedible, and diverting that biomass into insect production can turn waste into high‑value nutrition. I read that as a blueprint for habitats where every lettuce stem and wheat stalk that humans cannot eat becomes feedstock for larvae, which in turn become dinner, fertilizer or even building material. It is a systems engineer’s dream, but it only works if the biology is as reliable as the hardware.
Edible insects: mealworms, crickets and the astronaut menu
On the food front, NASA is already testing which insects can realistically feed crews on long missions without overwhelming them with complexity or risk. Mealworms and crickets stand out because they are compact, reproduce quickly and can thrive on plant scraps that would otherwise be discarded. When NASA explores edible insects like mealworms and crickets as the next astronaut food source, the goal is not to replace every familiar dish with bugs, but to add a dense, flexible protein source that can be grown inside the habitat itself rather than shipped from Earth.
That work is not just theoretical. Agency studies describe how NASA is exploring edible insects to provide sustainable nutrition during future deep‑space missions, with an eye toward integrating them into menus in ways that feel familiar, such as flours, pastes or mixed protein ingredients. I see a parallel with how plant‑based meats entered grocery stores on Earth: the key is not to ask astronauts to crunch whole crickets, but to fold insect protein into tortillas, stews or energy bars that fit existing culinary habits while slashing resupply needs.
All Things Bugs LLC and the rise of space entomophagy
To turn that concept into something astronauts can actually eat, NASA has leaned on specialized partners who understand both insect biology and food science. One of the most prominent is All Things Bugs LLC, a company that has spent years refining ways to turn insects into safe, palatable ingredients. Its proprietary research in the world of entomophagy, the practice of eating insects, has attracted international attention because it promises high‑protein powders and pastes that can be stored for long periods and rehydrated or cooked in simple ways, a crucial feature for cramped spacecraft kitchens.
In the context of deep‑space missions, the company’s work is more than a niche curiosity. When All Things Bugs LLC takes on NASA Deep Space Food Challenge problems, it is effectively prototyping how insect‑based foods could be produced, stored and served in environments where every gram and every watt count. I see a feedback loop here: techniques developed for Mars transit vehicles can be adapted to Earth agriculture, and vice versa, making insect protein more mainstream while giving NASA a broader base of experience to draw from.
Bumblebees in space: pollination and controlled habitats
Food security off‑world is not just about calories, it is also about keeping plants reproducing and producing fruit. That is where bumblebees enter the picture. In controlled environments with carefully tuned lighting, airflow, temperature and humidity, small bumblebee colonies can pollinate crops far more efficiently than human crews with brushes or automated devices. Researchers have shown that with the right environmental controls, these insects can sustain reliable harvests inside sealed modules, a capability that becomes critical as habitats scale up from experimental greenhouses to full agricultural decks.
The catch is that bees evolved under Earth gravity and open skies, so they can become disoriented and drift unpredictably in microgravity or poorly designed enclosures. Studies of how Dec bumblebee colonies behave in controlled lighting and airflow are therefore as much about habitat design as they are about insect biology. I read those experiments as early steps toward “pollination modules” that could be slotted into lunar or Martian bases, providing a living service that no mechanical system has yet matched in flexibility or energy efficiency.
Turning Martian dirt into soil: bugs as terraformers
Even the most efficient pollinators and protein sources will not matter if plants cannot grow in the first place, and Mars in particular presents a harsh starting point. Its regolith is dry, mineral‑rich and laced with chemicals that can be toxic to terrestrial life, while the planet’s thin atmosphere and cold temperatures make open‑air farming impossible. To make that lifeless dirt more pliable for plants, researchers are looking at how insects and the microbes they carry can help break down minerals, cycle nutrients and build up organic matter, effectively turning sterile dust into something closer to soil.
Reports on First and foremost challenges of Martian agriculture emphasize that without a way to transform regolith, any colony will remain dependent on imported substrates and fertilizers. I see insect‑driven soil conditioning as a potential game changer, because it leverages the same processes that built fertile ground on Earth over geological time, but compresses them into engineered bioreactors. If that works, Mars greenhouses could gradually expand their productive area without a matching increase in cargo from Earth, a prerequisite for any serious talk of self‑sufficiency.
Learning from bugs to grow food on Mars
NASA’s interest in insects on Mars is not limited to direct uses like eating or pollination; it also extends to what bugs can teach us about resilience in extreme environments. Many insect species tolerate wide swings in temperature, moisture and radiation, traits that are invaluable when designing biological systems for a planet with brutal dust storms and high‑energy particles. When NASA is described as learning from bugs to grow food on Mars, the phrase captures both literal experiments with insects and a broader effort to copy their strategies for survival and resource use.
That perspective is evident in work that frames NASA’s hopes of landing humans on Mars as inseparable from solving the problem of how to grow food there. One of the main problems for the colonization of Mars is the need to grow food locally, and insect‑inspired systems offer a way to do that with minimal inputs. I see this as a kind of biomimicry: by studying how insects manage water, build shelters and coordinate in colonies, engineers can design agricultural modules that are robust, modular and capable of recovering from partial failures, traits that any Martian farm will desperately need.
Chitin bricks: building with insect exoskeletons
Insects are not just food and farmhands; their bodies are also made of a remarkably useful material called chitin. This polysaccharide, found in the exoskeleton of insects and the hard structures of many invertebrates, can be combined with minerals to form tough, lightweight composites. For Mars, where traditional concrete is difficult to produce and steel is expensive to import, chitin‑based materials offer a way to turn biological byproducts into structural components for habitats, tools and even radiation shielding.
Research into Chitin as the next building material for Mars shows that when it is mixed with components like calcium carbonate, the resulting composite can achieve strength‑to‑weight ratios that rival some conventional materials while using far less energy to produce. I see a compelling synergy here: insect farms that feed astronauts and recycle waste could also supply chitin for 3D‑printed bricks or panels, turning every harvest into both dinner and infrastructure. In a resource‑scarce environment, that kind of multifunctional output is invaluable.
Designing habitats where insects can actually thrive
All of these ideas depend on a basic but nontrivial requirement: insects must be able to live and function inside artificial habitats that bear little resemblance to their native ecosystems. That means carefully controlling light cycles, airflow patterns, temperature gradients and humidity levels so that bees do not become disoriented, crickets do not overheat and larvae do not dry out. Experiments that track how Dec, Moon and, Mars habitats affect insect behavior are therefore as much about environmental engineering as they are about biology.
In practice, I expect future lunar and Martian bases to include dedicated “bug bays” that look more like high‑end vertical farms than traditional labs, with stacked enclosures, automated feeding systems and sensors tracking everything from carbon dioxide levels to wingbeat frequencies. The challenge will be to integrate those modules into the broader BLSS architecture without creating new vulnerabilities, such as pests escaping into electronics or allergens building up in the air. If designers get it right, though, the payoff is enormous: a living layer of redundancy that can keep food, materials and nutrient cycles running even when hardware fails or resupply is delayed.
The cultural leap: from squeamishness to stewardship
For all the technical promise, there is a human factor that cannot be ignored. Many people, including potential astronauts, are uneasy about eating insects or sharing close quarters with swarms of bugs, even if those bugs are confined behind transparent panels. Moving from that instinctive squeamishness to a sense of stewardship over insect colonies will require training, culinary innovation and perhaps a generational shift in attitudes. I suspect that as crews see firsthand how much mass and volume they save by relying on insect systems, and how much autonomy those systems provide, the psychological barriers will start to erode.
There is also a broader cultural story unfolding. As NASA and its partners normalize insect‑based foods and materials for space, they are likely to influence how people on Earth think about sustainability and resource use. Techniques developed to make bug protein appealing in orbit can be sustaining communities beyond our planet
