Closed bioregenerative life support systems: Applicability to hot deserts

open access: yesNature Precedings, 2010
AbstractWater scarcity in hot deserts, which cover about one-fifth of the Earth’s land area, along with rapid expansion of hot deserts into arable lands is one of the key global environmental problems. As hot deserts are extreme habitats characterized by the availability of solar energy with a nearly complete absence of organic life and water, space ...

Use of Photobioreactors in Regenerative Life Support Systems for Human Space Exploration

open access: yesFrontiers in Microbiology, 2021
There are still many challenges to overcome for human space exploration beyond low Earth orbit (LEO) (e.g., to the Moon) and for long-term missions (e.g., to Mars).

Modelling physical processes in higher plants using leaf replicas for space applications

open access: yesComptes Rendus. Mécanique, 2023
In the future, higher plant cultivation will be a key component of Bioregenerative Life-Support Systems. This will require a deep understanding of phenomena that play an important role at the core of plant metabolism and of their interaction with the ...

An Electro–Microbial Process to Uncouple Food Production from Photosynthesis for Application in Space Exploration

open access: yesLife, 2022
Here we propose the concept of an electro–microbial route to uncouple food production from photosynthesis, thereby enabling production of nutritious food in space without the need to grow plant-based crops.

The role of closed ecological systems in carbon cycle modelling [PDF]

open access: yes, 2011
Acquiring a mechanistic understanding of the role of the biotic feedbacks on the links between atmospheric CO2 concentrations and temperature is essential for trustworthy climate predictions.

Assessment of batch culture conditions for cyanobacterial propagation for a bioreactor in space

open access: yesFrontiers in Astronomy and Space Sciences, 2023
One important point in human space exploration is the reliable air, water and food production for the space crew, less dependent from cargo supply. Bioregenerative life support systems aim to overcome this challenge.

Mars Regolith Simulant Ameliorated by Compost as In Situ Cultivation Substrate Improves Lettuce Growth and Nutritional Aspects [PDF]

open access: yes, 2020
Heavy payloads in future shuttle journeys to Mars present limiting factors, making self-sustenance essential for future colonies. Therefore, in situ resources utilization (ISRU) is the path to successful and feasible space voyages.

Current Concepts and Future Directions of CELSS [PDF]

open access: yes, 1985
Bioregenerative life support systems for use in space were studied. Concepts of such systems include the use of higher plants and/or microalgae as sources of food, potable water and oxygen, and as sinks for carbon dioxide and metabolic wastes.
