Radiation environment in exploration-class space missions and plants’ responses relevant for cultivation in Bioregenerative Life Support Systems [PDF]

open access: yesFrontiers in Plant Science, 2022
For deep space exploration, radiation effects on astronauts, and on items fundamental for life support systems, must be kept under a pre-agreed threshold to avoid detrimental outcomes.

Development of Nitrogen Recycling Strategies for Bioregenerative Life Support Systems in Space [PDF]

open access: yesFrontiers in Microbiology, 2021
To enable long-distance space travel, the development of a highly efficient and robust system to recover nutrients from waste streams is imperative. The inability of the current physicochemical-based environmental control and life support system (ECLSS ...

Approaches to nitrogen fixation and recycling in closed life-support systems

open access: yesFrontiers in Astronomy and Space Sciences, 2023
N2 fixation is essential to the sustainability and operation of nitrogen systems but is energetically expensive. We developed a model and used sensitivity analysis to identify the impact of aerobic and anaerobic waste digestion, crop harvest index, rates

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.

Use of cryogenic components of propellants for liquid-propellant rocket engines and in life support systems of manned space vehicles [PDF]

open access: yesMATEC Web of Conferences, 2020
The cited materials show the use of oxygen, hydrogen, liquefied natural gases (methane) and fluorine as components of the fuel for liquid-propellant rocket engines (LRE). The reasons for the need to use oxygen as an oxidizing agent are indicated.
