# Launch, wait, or do not launch
> **Evidence boundary:** The gates in this lesson are a proposed governance framework, not a legal authorization process or a validated safety case. NASA lifecycle methods are relevant process evidence but do not confer authority over an interstellar mission. Rights, medicine, ecology, nuclear systems, cyber, dual use, and planetary protection require qualified independent review and legitimate public institutions that do not yet exist.
## Plain-language summary
A credible program decides more than whether to launch.
At each stage it must be able to choose:
- **Proceed** with a bounded next step.
- **Wait** for evidence, capacity, or legitimacy.
- **Redirect** toward a safer or more useful alternative.
- **Stop or abandon** a branch.
- **Do not launch** as a valid final result.
Approval of research is not approval of a vehicle. Approval of a vehicle is not approval to launch. Departure is not permission to settle a world.
Good gates state evidence and authority before results are known. They expire. They preserve minority findings and appeals. Some conditions—rights, voluntary consent, independent medical authority, disability access, biosafety, and planetary protection—are vetoes rather than points that propulsion performance can outweigh.
## Why gates begin before hardware
Programs acquire momentum. A concept creates a team; a team creates contracts; contracts create infrastructure; infrastructure creates political and financial pressure to continue. If stopping rules are invented only after a failure, they will be negotiated by institutions that depend on not stopping.
The first gate should therefore govern the research program itself. It should require a real near-term beneficiary, a measurable gap, reversible testing, bounded dual-use and environmental risk, publication of limitations and negative results, visible conflicts, funded independent review, and a decommissioning path. If a project cannot pass that gate, its distance from launch is irrelevant.
## What NASA lifecycle practice contributes
NASA organizes programs and projects into lifecycle phases separated by Key Decision Points. Its Systems Engineering Handbook describes technical reviews with defined purpose, objectives, entry criteria, success criteria, review teams, findings, and action resolution. Its decision-analysis process calls for a defined decision, alternatives, criteria, authority, evidence, uncertainty, and documented comparison.
These are mature process patterns for present programs. They do not answer who may authorize a civilization-scale interstellar commitment. They do show why a gate must be more than a celebratory milestone.
The handbook allows criteria to be mandatory or enhancing. An option that does not meet a mandatory criterion is removed rather than compensated by a high score elsewhere. That distinction is essential for rights and safety.
## The anatomy of a real gate
Every gate should publish the exact bounded act, decision authority, affected publics, alternatives, entry criteria, mandatory vetoes, enhancing criteria, and evidence dossier. It should also name reviewer competence, independence, compensation, conflicts, recusals, and minority findings. The resulting decision needs a rationale, bounded conditions, monitoring, expiration, and reopening triggers.
Minutes, dissent, assumptions, and unresolved findings belong in the record. A slide showing green boxes does not.
## Mandatory criteria are not weighted preferences
A weighted decision matrix can hide a moral failure. High speed, low cost, or scientific prestige must not “make up for” forced reproduction, inaccessible emergency systems, unbounded contamination, or the absence of braking.
Proposed noncompensatory conditions include:
- No architecture that depends on forced reproduction, forced abortion, nonconsensual genetic intervention, disability exclusion, or hereditary legal status.
- No crew launch without independently supported braking, arrival, maintenance, health, and ecological assurance.
- No settlement commitment where credible indigenous life is detected without a legitimate protective international framework; presumption should favor non-interference.
- No life-critical AI with unreviewable authority or no safe non-AI operating mode.
- No founder, owner, employer, or vendor with unappealable control over citizenship, oxygen, medical care, or political status.
- No operational dual-use engagement without screening, independent stop-work authority, and enforceable limits.
- No decision package that suppresses material counterevidence or unresolved reviewer disagreement.
Qualified reviewers may narrow or strengthen these conditions. They may not silently convert them into marketing risk factors.
## A proposed sequence of gates
The sequence below is illustrative. Passing one authorizes only its stated next step.
### Gate 0: research legitimacy
Question: should this research or coordination project begin?
Evidence includes the beneficiary, reversible experiment, information hazards, resource use, conflicts, review plan, and decommissioning. Outcomes include a bounded study, redirect, added controls, or refusal.
### Gate 1: precursor experiment
Question: should a laboratory, analog, robotic, habitat, ecological, medical, cyber, or governance experiment proceed?
Evidence includes protocol, consent, inclusion, hazards, stopping criteria, data governance, independent monitoring, recovery, and publication. Human and biological research requires the applicable ethics and regulatory review.
### Gate 2: integration testbed
Question: should multiple systems be coupled at higher consequence?
Evidence includes interfaces, correlated failures, fault injection, manual modes, reserves, maintenance, accessibility, environmental impact, and verified shutdown.
### Gate 3: reference architecture
Question: does a candidate mission describe the whole lifecycle honestly enough to remain under study?
Evidence includes destination, speed, braking, arrival, population assumptions, ecology, industry, health, governance, law, costs, alternatives, uncertainty, and explicit unknowns. This gate approves testing, not construction.
### Gate 4: autonomous Solar System demonstration
Question: can the architecture operate for a defined period where rescue or independent inspection remains possible?
Evidence includes autonomous maintenance, ecological recovery, civic participation, disability access, medical independence, cyber restore, supply accounting, and safe return or decommissioning. Analog failure is useful evidence.
### Gate 5: interstellar robotic characterization
Question: is a robotic mission justified and sufficiently protective?
Evidence includes target science, contamination control, Article IX due regard and consultation, COSPAR policy where applicable, mission purpose, dual use, and public reporting.
### Gate 6: vehicle construction
Question: should society allocate material and authority to build a crewed vehicle?
Evidence must exceed paper architecture: representative demonstrations, credible supply chains, lifecycle cost, independent assurance, jurisdiction, rights, ownership limits, labor protection, environmental assessment, and funded decommissioning. Approval expires after material change.
### Gate 7: departure authorization
Question: may people be placed beyond realistic rescue and return?
This requires legitimate public authority, international consultation, uncoerced informed consent, independent resident advocacy, destination evidence, health and reproductive rights, tested maintenance and ecology, braking, arrival options, cyber recovery, and enforceable stop conditions. No private organization can authorize this on behalf of humanity.
### Gate 8: irreversible cruise transitions
Question: should the mission cross a point after which return, rescue, target change, or safe loiter becomes materially harder?
Residents, not only Earthside institutions, need authority and current evidence. Approvals must be revisited as the society and destination knowledge change.
### Gate 9: arrival and settlement
Question: should the vehicle enter orbit, deploy infrastructure, descend, introduce Earth life, or establish a settlement?
Each action is separate. A launch centuries earlier cannot authorize contamination or settlement after evidence reveals life, unsafe conditions, or better alternatives. Orbital habitation, robotic study, target change, or non-settlement must remain possible where physics permits.
## Who decides?
No existing body has demonstrated complete legitimacy for every gate. A credible structure would distribute authority among:
- Relevant states and international institutions under applicable law.
- Independent technical, medical, ecological, cyber, and safety authorities.
- Affected communities around Earthside facilities and environmental impacts.
- Residents and future onboard civic institutions.
- Planetary-protection and astrobiology expertise.
- Disability-led, child-rights, reproductive-justice, labor, and human-rights review.
- Courts, ombuds, or appeal bodies independent of the vehicle owner.
The exact allocation requires law and politics, not only engineering. Authority should follow affected interests and competence while preventing any actor from controlling all evidence, operations, medicine, and appeal.
## Future people and expiring consent
Departing adults can consent to bounded known risks for themselves. They cannot give consent for people later born aboard or permanently waive their descendants’ rights.
The UNESCO future-generations declaration emphasizes freedom of choice in political, economic, and social systems and asks present generations to consider consequences before major projects. The Convention on the Rights of the Child recognizes children’s right to be heard in matters affecting them.
Practical consequences:
- Founding documents must be amendable.
- Youth voice must be institutional, not symbolic.
- No approval can require descendants to settle.
- Education must include mission criticism and alternatives.
- Onboard gates need current local consent, accessible evidence, dissent, and appeal.
- Where no physical exit exists, civic refusal and safe alternative operations become more important, not less.
## Planetary protection is an arrival veto
Outer Space Treaty Article IX directs states parties to avoid harmful contamination and undertake consultation where potentially harmful interference is expected. COSPAR’s policy supplies present mission-category guidance.
A generation ship exceeds current policy assumptions in scale, duration, biological inventory, and purpose. That gap is not permission. It increases the burden for research, international legitimacy, and conservative arrival choices.
High-confidence robotic characterization should precede crew launch. Credible indigenous life should trigger a presumption against settlement and biological release. Uncertainty cannot be scored away by the cost already incurred in transit.
## Gate failure is information
A failed gate should produce a public explanation, identify unsupported claims, preserve negative results, protect workers and whistleblowers, and execute a safe shutdown or transfer. “Wait” needs a review date or evidence trigger. “Stop” needs orderly closeout. “Do not launch” must remain a respected outcome.
## Prevent gate capture
Capture includes dependent reviewers, post-result criteria changes, unavailable evidence, schedule pressure treated as proof, founders acting as final authority, late rights review, buried minority findings, and approval conditions without owners or budgets.
Controls include independent budgets, published conflicts, random audit, recusal, external appeal, reviewer rotation, whistleblower protection, and a rule that unresolved competence gaps block—not accelerate—the next stage.
## Evidence ledger
- **L01-05-A — Defined lifecycle reviews and decision analysis are mature practices for current space programs.** Basis: demonstrated institutional practice. Readiness: operational within NASA’s scope. Confidence: strong. Transfer to a civilization-scale mission requires new authority and criteria.
- **L01-05-B — Mandatory criteria can disqualify an option rather than be offset by enhancing criteria.** Basis: NASA decision-analysis guidance and normative extension. Readiness: operational as a method. Confidence: strong about the method; the proposed rights vetoes need specialist review.
- **L01-05-C — Current space law establishes state responsibility and contamination-related duties.** Basis: treaty text. Readiness: operational for parties and present activities; uncertain for interstellar duration and governance. Confidence: strong about Articles VI and IX, tentative about future application.
- **L01-05-D — No private organization can legitimately authorize an irreversible mission on behalf of all humanity.** Basis: normative governance conclusion informed by current law and affected-public interests. Readiness: early research for an adequate institution. Confidence: supported; exact authority remains unresolved.
- **L01-05-E — Launch, wait, redirect, stop, and do-not-launch must remain real outcomes.** Basis: normative option-preservation rule. Readiness: operational as program governance. Confidence: strong within GShips policy.
Linked corpus claims: `claim-01-10`, `claim-10-10`, `claim-17-10`, `claim-19-10`, and `claim-20-10`. See the claim registry for each record's current evidence grade and independent-review state.
## Assumptions and limits
- NASA program gates are used as process analogs, not legal authority or safety certification.
- A future mission could require additional or differently ordered gates.
- Legal duties depend on jurisdiction, treaty participation, national law, and future developments.
- Some evidence may require privacy or security protection; this does not justify secret criteria or unreviewable authority.
- “Independent” requires disclosure and structural separation, not merely a reviewer from another department.
- Physical irreversibility and social reversibility are different; both need explicit analysis.
## What would change this conclusion?
The sequence should change when tested programs, new law, or independent review show that gates are missing, misplaced, or create perverse incentives. Specific vetoes should be refined through human-rights, medical, disability, ecological, legal, and affected-public review, but evidence that a veto is inconvenient is not evidence against it. A legitimate international authorization framework could resolve some authority questions. Demonstrated safe target characterization, braking, habitat autonomy, and constitutional resilience could move evidence at later gates without pre-authorizing launch. Evidence that no practicable institution can protect rights or no architecture can survive while preserving them should produce a do-not-launch conclusion.
