No relationship or action implied. This page is a task-specific editorial hypothesis. Candidate organizations remain indexed only; event participation, opportunity applications, outreach, procurement, and commitments require separate authorization.

Public question

Can a testbed account for air, water, food, nutrients, waste, labor, energy, losses, intervention, and recovery across a declared boundary?

Compare closed-loop claims through transparent mass, energy, maintenance, and failure ledgers rather than closure percentages alone.

Connected capability areas

Institutional roles needed

  • basic research
  • applied rd
  • operator
  • testbed facility
  • standards assurance

Preferred engagement modes

  • public dataset comparison
  • replication protocol
  • bounded testbed study

Leadership pathways

Evidence required before advancement

  • Declared system boundary and interval
  • Measured inventories, flows, uncertainty, labor, and energy
  • Failure injection and ecological recovery criteria
  • Negative-result and transfer-limit publication

Potential organizations for bounded review

No aggregate score exists. Tiers apply only to this task, and every unresolved mandatory veto constrains the candidate to monitoring.

monitor

ESA MELiSSA

The reviewed profile directly addresses regenerative life support and integration, but no current research access, reviewer availability, or independent validation is established.

Bounded next action—not undertaken: Compare public MELiSSA boundary conditions and metrics with the GShips material-accounting template.

University of Arizona Biosphere 2

The reviewed profile supports controlled-ecosystem and user-facility relevance, while a suitable project, capacity, cost, and participant boundary remain unverified.

Bounded next action—not undertaken: Review public user-facility terms against one nonhuman, low-consequence material-accounting proposal.

What would change this task?
Representative integrated data, a verified access path, or evidence that the accounting boundary omits a decisive stream would change the task.

Assumptions and limits

  • This task is an editorial coordination model, not a partnership, procurement plan, endorsement, invitation, eligibility finding, or authorization to act.
  • Candidate tiers are task-specific and noncompensatory. No aggregate score exists, and a failed mandatory veto blocks advancement.

What would change this page?

Representative integrated data, a verified access path, or evidence that the accounting boundary omits a decisive stream would change the task.

Declared conflicts

  • No facility, sponsor, customer, or partner relationship exists; selection may affect a future commercial research roadmap.
  • The maintainer intends to explore a commercial venture based on some GShips work. No entity, outside funding, customer, sponsor, or indexed-organization relationship currently exists.
