What if finding alien life doesn’t unite humanity—but tears it apart?
The Looming Reality of Space Microbes
Many space missions now actively search for life beyond Earth. But are we truly prepared for the fallout if they succeed? Microbes from space have long fueled science fiction plots, from “Project Hail Mary” to “The Andromeda Strain.” Yet with each new launch, discovering extraterrestrial life in a microbial form becomes more plausible. What will the response be back here on Earth when scientists confirm extraterrestrial microbes? Will international policy and security communities handle the consequences?
When you hear about extraterrestrial life, your mind likely jumps to intelligent beings like those in Hollywood films. However, even the confirmation of microbial life originating elsewhere—a far more probable scenario—would represent a paradigm-shifting event. Consequently, thinking about these consequences early can help nations and the international community prepare effectively.
Our team comprises a full professor of international affairs with a Ph.D. in chemistry, an emerging scholar in space policy and security, and an expert on social and political implications of frontier technologies such as AI, space, quantum, and energy sources. We focus on how emerging science and technologies affect global conflict and cooperation.
Multiple Mars landers have identified vast amounts of frozen and liquid water on the red planet—an essential ingredient for life. Japan’s Hayabusa2 spacecraft returned samples from a near-Earth asteroid containing uracil, a component of RNA and a building block of life. Meanwhile, uncrewed probes like NASA’s Europa Clipper and the European Space Agency’s Jupiter Icy Moons Explorer are en route to conduct detailed reconnaissance of Jupiter’s moons, investigating whether they harbor conditions suitable for life. Data from the James Webb Space Telescope and future missions targeting Saturn’s icy moon Enceladus further increase the likelihood of discovering extraterrestrial microbial life.
International Governance Gaps Exposed by Discovery
The discovery of microbial life would expose significant gaps in international governance related to space. Existing agreements, including the Outer Space Treaty of nineteen sixty-seven, provide basic space law guidelines. However, they remain ill-equipped to address the complexities posed by extraterrestrial biology.
The Outer Space Treaty dictates peaceful use of outer space and prohibits any single nation from claiming ownership or exerting sovereignty over celestial bodies. Yet it says almost nothing about who can own extraterrestrial organisms or how to handle biosecurity risks. Moreover, it offers no direction for using, preserving, or destroying living things—such as bacteria or fungi—that may be discovered in space.
How will nations agree on protocols for handling potentially hazardous space microbes? What legal framework governs the extraction or exploitation of extraterrestrial biological resources? These questions remain unanswered, creating a dangerous vacuum.
Historical Analogies for Space Discovery Outcomes
While we have not yet discovered extraterrestrial life, major geopolitical events help researchers understand potential consequences. The space race of the nineteen fifties and sixties, for instance, led to lunar exploration but was driven by a Cold War power struggle. Instead of fostering cooperation, both countries experienced renewed nationalism and used new discoveries to invest in military capabilities.
On the other hand, consider how states respond to asteroid threats. Since an asteroid poses a truly existential danger from space, preventing the worst-case scenario requires cooperation and forward thinking. Astronomers have built a global, collaborative network to monitor potential threats and sound alarms. This network demonstrates that nations can set aside terrestrial rivalries when they perceive something from space as an existential threat.
Similarly, the International Space Station shows how competing great powers can cooperate in space. Countries have collaborated to solve issues with specific, short-term, and clearly identified goals. These examples illustrate a range of possible reactions to discovering space microbes: the situation could renew space races and lead to militarization, or it could create unprecedented cooperation.
Cooperative Outcome: Global Scientific Collaboration
First among the three main possible outcomes is a cooperative scenario, reminiscent of the asteroid threat network or the International Space Station. In this pathway, nations collaborate to regulate research, share data, protect the planet, and advance shared interests. This outcome is not inherently benign or malignant; it could involve expanding international organizations or creating new legal instruments.
For example, countries might establish a global biosecurity protocol specifically for extraterrestrial samples, similar to the Biological Weapons Convention but tailored to space. They could also create an international repository for space microbes, ensuring equitable access for research. What incentives would drive nations toward cooperation? The mutual benefit of understanding life’s origins and the shared risk of contamination might outweigh competitive urges.
Competitive Outcome: Strategic Rivalry and Biopiracy
Second is a competitive outcome characterized by strategic rivalry. Like during the space race, nations could fight for technological superiority. They might attempt to monopolize access to extraterrestrial microbes or leverage biological discoveries for economic or military advantage.
Scientific breakthroughs derived from extraterrestrial organisms could lead to innovations in medicine, agriculture, energy, and beyond. However, these organisms could also be weaponized, intentionally or accidentally, amplifying biosecurity risks. Consequently, discovering microbial life could create a new form of technological competition merging space exploration with biological research and development.
The increasing role of private companies like SpaceX complicates this dynamic. These companies receive government contracts, blurring the lines between commercial civilian and strategic activities. For instance, approximately sixty percent of all satellites currently orbiting Earth belong to SpaceX’s Starlink subsidiary. The company can—and has—chosen to block access selectively, aligning with its political priorities. When commercial interests and national priorities diverge, who gains or loses access becomes uncertain.
Biopiracy issues may also arise. Biopiracy refers to patenting indigenous knowledge or natural resources—such as microbes—for profit. The Budapest Treaty prohibits claiming ownership of naturally occurring microbes on Earth, but no equivalent exists for space microbes. Could a private company patent a microbe found on Mars? What happens if that microbe has commercial value for pharmaceuticals or industrial processes?
Isolationist Outcome: Biosecurity Fears and Political Distrust
Third is an isolationist outcome, where states sever involvement in international cooperation due to biosecurity concerns or political distrust. The potential for unknown biological risks, however minimal, could trigger precautionary restrictions on data sharing, limiting collaboration. Countries may lose or gain allies as they grapple with whether the microbe could harm humans or the environment, or be developed into a biological weapon.
In this scenario, nations might impose strict quarantine measures on returning spacecraft, similar to the Apollo program’s lunar quarantine but far more rigorous. They could also restrict scientists from sharing genetic sequences of extraterrestrial organisms, fearing misuse. How would such isolation affect global scientific progress? Would it drive some countries to pursue secret, unregulated research?
Emerging Technologies Shape the Outcomes
Emerging technologies will influence all three outcomes. Artificial intelligence and machine learning already process astronomical data and identify potential biosignatures. Nanotechnology and advances in life sciences and engineering could allow researchers to study, modify, or exploit extraterrestrial microbes if given access.
Countries must prepare not only for scientific implications but also for societal and political reverberations. The politicization of scientific discoveries could complicate or change domestic and international responses. Misinformation about the microbes could shape policy and public reaction. For instance, how might media sensationalism affect public trust in space agencies? Could conspiracy theories about alien pathogens undermine international cooperation?
Scenario-Based Planning for the Unprecedented
The discovery of extraterrestrial microbial life would not merely mark a scientific milestone; it would be a geopolitical event. Rather than attempting to predict a singular outcome, policymakers could adopt scenario-based planning approaches to anticipate and prepare for a range of possibilities. In these approaches, participants explore multiple futures through structured activities similar to professional wargaming or path games, systematically testing strategies under realistic uncertainty.
Such planning should involve not only space agencies but also public health officials, defense departments, legal experts, and ethicists. What would happen if a private company discovers life first? How should international law adapt? What public communication strategies prevent panic? These questions demand answers before the discovery occurs.
Conclusion: Are We Ready?
In our view, the question is not whether humanity will discover life beyond Earth, but whether it is prepared for the consequences when it does. The likelihood increases with each mission, yet the governance framework remains incomplete. By examining historical analogies, considering multiple outcomes, and engaging in proactive planning, we can turn a potential crisis into an opportunity for global cooperation. But the time to act is now—before the microbes arrive.
