The International Space Station relies on environmental control and life support systems designed to create closed loops for water, oxygen, and carbon dioxide management.

The analysis

The retrieved literature consistently supports the claim that environmental control and life support systems (ECLSS) on space stations function to achieve loop closure for essential consumables like water, oxygen, and carbon dioxide, matching the scope of the claim.
