Selection note: Curated because this 1990 conference paper from Legacy CDMS specifically covers “Environmental Control and Life Support System Evolution”; its abstract describes Viewgraphs on Environmental Control and Life Support System (ECLSS) evolution are presented. The Space Station Freedom ECLSS will have to accommodate the changes to Freedom… This materially informs GShips regenerative life support.
Evidence boundary: NTRS lists open full text, but this pass assessed catalog metadata and abstract rather than independently validating the document. Inclusion is contextual discovery support, not automatic evidence for a GShips claim.

Source-supplied abstract
Viewgraphs on Environmental Control and Life Support System (ECLSS) evolution are presented. The Space Station Freedom ECLSS will have to accommodate the changes to Freedom as it evolves over the design life of 30 years or more. Requirements will change as pressurized modules are added, crew numbers increase, and as the tasks to be performed change. This evolution will result in different demands on the ECLSS and the numbers ECLSS will have to adapt. Technologies other than the baselined ones may be better able to perform the various tasks and technological advances will result in improved life support hardware having better performance, increased reliability, reduced power consumption, weight, and volume, greater autonomy, and fewer resupply requirements. A preliminary study was performed to look at alternative technologies for life support and evaluate them for their integration requirements.
Abstract text has not been adopted as a GShips conclusion.
