“…Life support functions, such as waste degradation, water recovery, and oxygen production, can be carried out by microorganisms, thus, sustaining life in space. In fact, several studies have shown that fungi, bacteria, and cyanobacteria enhance vitamin production, water recycling, air decontamination, and waste management under space conditions ( Acevedo-Rocha et al., 2019 ; Aydogan-Cremaschi et al., 2009 ; Carillo et al., 2020 ; Lindeboom et al., 2020 ; Roberts et al., 2004 ). In particular, fungal biotechnology can be harnessed such that space stations are self-sustaining with respect to food, pharmaceuticals, waste recycling, and plastic degradation for long-term missions ( Cortesão et al., 2020 ).…”

Summary Microbial research in space is being conducted for almost 50 years now. The closed system of the International Space Station (ISS) has acted as a microbial observatory for the past 10 years, conducting research on adaptation and survivability of microorganisms exposed to space conditions. This adaptation can be either beneficial or detrimental to crew members and spacecraft. Therefore, it becomes crucial to identify the impact of two primary stress conditions, namely, radiation and microgravity, on microbial life aboard the ISS. Elucidating the mechanistic basis of microbial adaptation to space conditions aids in the development of countermeasures against their potentially detrimental effects and allows us to harness their biotechnologically important properties. Several microbial processes have been studied, either in spaceflight or using devices that can simulate space conditions. However, at present, research is limited to only a few microorganisms, and extensive research on biotechnologically important microorganisms is required to make long-term space missions self-sustainable.

“…Also, the crew life will be totally dependent on the Environment Control and Life Support System (ECLSS) of the spacecraft. A life-support system for manned missions is a set of technologies to regenerate the basic lifesupport elements, i.e., oxygen, potable water, and food during longtime spaceflights, such as in low-Earth orbit, on the Moon, on Mars, or beyond [3]. Life support technologies are also being studied for colonization of the Moon [4] and Mars [5,6].…”

In deep space manned travels, the crew life will be totally dependent on the environment control and life support system of the spacecraft. A life-support system for manned missions is a set of technologies to regenerate the basic life-support elements, such as oxygen and water, which makes resilience a paramount feature of this system. The resilience of a complex engineered system is the ability of the system to withstand failures, continue operating and recover from those failures with minimum disruption. Resilient design is a new design framework on which the main goal is to quantify system resilience upfront in order to guide the design team during the conceptual design stage. In this article, we present a tool that combines a rule-based approach with a Monte Carlo-based approach to evaluate the resilience of a proposed environment control and life support system designed for deep space travel. Based on the results found, we explore a few design alternatives in order to increase system resilience.
