First Contact Part 1: How Prepared Are We?

Humanity has detailed, consensus-style guidelines for what should happen after detecting extraterrestrial intelligence—but there’s no comparable, enforceable government plan for the far more dangerous scenario of aliens physically landing on Earth. The core gap is stark: the main official documents exist as recommendations, not binding rules, and they mainly address signal detection rather than contact-by-craft.

Since the 1970s, efforts to find extraterrestrial intelligence have included NASA’s Project Cyclops, which aimed to identify the best way to search for alien signals. Over time, funding for SETI work has shrunk, leaving parts of the search increasingly dependent on private donations. Yet the question driving this discussion isn’t how to find signals—it’s how prepared society is to respond once something credible appears.

The main framework is the “Declaration of principles for activities following the detection of extraterrestrial intelligence,” drafted by the SETI Permanent Committee of the International Academy of Astronautics (IAA) and later endorsed by many researchers. It lays out eight provisions. First, any detected extraterrestrial signal should be verified as coming from an intelligent source before public announcement. Second, the discoverer should coordinate with other signatories and notify national authorities before going public. Third, once confirmed, the astronomical community should be informed alongside the UN Secretary-General and relevant global scientific unions. Fourth, the discovery should then be made public, with the discoverer allowed to issue the first public announcement. Fifth, all relevant data should be published and stored in accessible, long-term form. Sixth, if the evidence comes via electromagnetic signals, the UN Secretary-General should be contacted so the International Telecommunication Union can potentially minimize use of the frequency bands involved. Seventh, no one should respond to an observed extraterrestrial intelligence without international agreement under separate procedures. Finally, the IAA’s SETI Permanent Committee and Commission 51 of the International Astronomical Union should continually review detection procedures.

A supplementary draft—the “proposed agreement on the sending of communications to extraterrestrial intelligence”—aims to create an international commission for deciding how to respond, emphasizing justice, cultural diversity, honesty, and respect for property and territory. It also restricts unilateral action by any nation without committee consent, and suggests that if a signal seems hostile, the UN Security Council should decide.

But these documents have no official legal power. Many scientists expect they would be ignored under real-world pressure. That concern becomes even sharper when shifting from long-distance signals to physical contact. For a landing scenario, the transcript notes that no public government protocols exist. Seth Shostak of the SETI Institute says he’s unaware of any government programs—covert or otherwise—prepared for an extraterrestrial arrival. He points to a 1997 incident involving a promising signal that never triggered the kind of coordinated response one might expect from major institutions.

The underlying problem is uncertainty. Any civilization capable of interstellar travel would likely be hundreds of years ahead, making it hard to predict what an arrival would mean—or what humans could say or do that wouldn’t already be obvious to a more advanced society. A knee-jerk military response, in particular, could go badly. The transcript’s takeaway is that preparation is limited: guidelines exist for detection, but Earth lacks a clear, enforceable playbook for first contact by craft, and the biggest risk may be acting too fast without knowing the “game” being played.
