A manned spacecraft, with a life support system configured to remove metabolic carbon dioxide (CO 2) from the spacecraft's internal atmosphere, comprising a macro-porous ion-exchange resin for carbon dioxide (CO 2) absorption, and configured to regenerate the macro-porous ion-exchange resin after a carbon dioxide (CO 2) binding, for the purpose of removing-solving the carbon dioxide (CO 2) from of the macro-porous ion-exchange resin, wherein the regeneration of the macro-porous ion exchange resin is effected by a usage of slightly overheated water vapor under atmospheric conditions and the resulting expulsion of the CO 2 or by applying a negative pressure, and wherein the carbon dioxide (CO 2), after removing from the macro-porous ion-exchange resin, is supplied to a pipeline system of the life support system, which is intended to distribute the carbon dioxide (CO 2) in the spacecraft, and with at least one work chamber, which is configured for a performance of an extraction and/or purification process with carbon dioxide (CO 2) as a solvent, wherein the carbon dioxide (CO 2) required for the extraction and/or purification process in the work chamber is supplied by the life support system, and with a further work chamber, which is configured for a performance of an extraction and/or purification process with carbon dioxide (CO 2) as a solvent, and which is directly connected to the life support system, at a distance from the work chamber. with a life support system configured to remove metabolic carbon dioxide (CO 2) from the spacecraft's internal atmosphere, comprising a macro-porous ion-exchange resin for carbon dioxide (CO 2) absorption, and configured to regenerate the macro-porous ion-exchange resin after a carbon dioxide (CO 2) binding, for the purpose of removing-solving the carbon dioxide (CO 2) from of the macro-porous ion-exchange resin, wherein the regeneration of the macro-porous ion exchange resin is effected by a usage of slightly overheated water vapor under atmospheric conditions and the resulting expulsion of the CO 2 or by applying a negative pressure, and wherein the carbon dioxide (CO 2), after removing from the macro-porous ion-exchange resin, is supplied to a pipeline system of the life support system, which is intended to distribute the carbon dioxide (CO 2) in the spacecraft, and configured to remove metabolic carbon dioxide (CO 2) from the spacecraft's internal atmosphere, comprising a macro-porous ion-exchange resin for carbon dioxide (CO 2) absorption, and configured to regenerate the macro-porous ion-exchange resin after a carbon dioxide (CO 2) binding, for the purpose of removing-solving the carbon dioxide (CO 2) from of the macro-porous ion-exchange resin, wherein the regeneration of the macro-porous ion exchange resin is effected by a usage of slightly overheated water vapor under atmospheric conditions and the resulting expulsion of the CO 2 or by applying a negative pressure, and wherein the carbon dioxide (CO 2), after removing from the macro-porous ion-exchange resin, is supplied to a pipeline system of the life support system, which is intended to distribute the carbon dioxide (CO 2) in the spacecraft, and with at least one work chamber, which is configured for a performance of an extraction and/or purification process with carbon dioxide (CO 2) as a solvent, wherein the carbon dioxide (CO 2) required for the extraction and/or purification process in the work chamber is supplied by the life support system, and with a further work chamber, which is configured for a performance of an extraction and/or purification process with carbon dioxide (CO 2) as a solvent, and which is directly connected to the life support system, at a distance from the work chamber.
