“…A controlled experimental environment was designed and built based on the hygiene area of a space station with support from the China Astronauts Centre ( Figure 1 ). Based on the reports on the International Space Station by Messerschmid and Borrego [ 4 , 46 , 47 ], the various functional elements were optimised to provide an integrated experimental system of the hygiene area in the space station in order to ensure reliability and accuracy of the experiment. This simulated environment included four subsystems: temperature and humidity monitoring, illumination system, physiological monitoring, and urine/stool collector simulator.…”

“…In long-term manned space missions, astronauts may suffer unstable physiological and psychological states in confined, narrow, isolated environments, which brings unprecedented challenges to space mission support and manned space engineering [ 1 , 2 , 3 ]. As an important measure for ensuring the success of manned space missions, habitability research needs to consider the harmony of the astronauts’ body mechanics, but also their psychological and physical health [ 4 , 5 ]. Many NASA reports indicate that habitability is highly related to human factors, behavioural health, environmental interaction and human-computer interaction [ 6 ].…”

The hygiene area is one of the most important facilities in a space station. If its environmental lighting is appropriately designed, it can significantly reduce the psychological pressure on astronauts. This study investigates the effect of correlated colour temperature (CCT) on heart rate, galvanic skin response, emotion and satisfaction in the hygiene area of a space station. Forty subjects participated in experiments in a hygiene area simulator with a controlled lighting environment. The lighting conditions included 2700 K, 3300 K, 3600 K, 5000 K and 6300 K; physiological responses (heart rate, galvanic skin response), as well as emotion and satisfaction, were recorded. The results showed that CCT significantly influenced the participants’ physiological and subjective responses in the space station hygiene area. 6300 K led to the best emotion and satisfaction levels, the highest galvanic skin response and the lowest heart rate. The opposite was true for 2700 K.

Most spaceborne scientific experiment applications require a microgravity environment. The current high-precision accelerometers used for the spaceborne vibration isolation system generally have a noise floor of sub-μg/√Hz, which cannot meet the demand of higher-level microgravity measurements. This article introduces a micro-electromechanical system (MEMS) acceleration sensor that has a noise floor of 2–5 ng/√Hz and an input range of more than ±2 mg. Its three-component version, the MEMS microgravity measurement module (MEMS-M3), is designed to measure accelerations in the space microgravity environment and might be used in the active vibration isolation system for higher-level microgravity scientific experiments in the future. The MEMS-M3 has a volume of 105 × 90 × 115 mm3, a weight of 1.2 kg, and power consumption of 3 W. The performance of the MEMS-M3 has been characterized on the ground and a series of preflight reliability experiments have been conducted. Then, the MEMS-M3 installed inside the test spacecraft has been carried by the Long March 5B rocket (CZ-5B) to the low Earth orbit at 10:00 on May 5, 2020, and returned to Earth ground at 5:00 on May 8, 2020, both in UTC time. During the on-orbit period, the MEMS-M3 has been switched on for 11 h. After data processing, the transient, periodic, and steady accelerations can be observed by the MEMS-M3 and a much noisier shelf product IMU STIM300, verifying the functionality of the MEMS-M3. Apart from application in active vibration isolation systems for spaceborne scientific experiments, it can also be used for drag-free control of satellites and other space applications.

“…In the process of manned space flight and extraterrestrial exploration, astronauts are faced with basic material and energy requirements. An astronaut consumes about 820-840 g of oxygen and exhales 1000-1040 g of carbon dioxide a day [1]. It is expensive and technically difficult to carry all the consumables from Earth for long-term manned extraterrestrial exploration.…”

A Membrane Reactor with Microchannels for Carbon Dioxide Reduction in Extraterrestrial Space

Long-term continuous oxygen supply is of vital importance during the process of space exploration. Considering the cost and feasibility, in situ resource utilization (ISRU) may be a promising solution. The conversion of CO2 to O2 is a key point for ISRU. In addition, the utilization of the abundant CO2 resources in the atmosphere of Mars is an important topic in the field of manned deep space exploration. The Sabatier reaction, Bosch reaction, and solid oxide electrolysis (SOE) are well-known techniques for the reduction of CO2. However, all the above techniques need great energy consumption. In this article, we designed an electrochemical membrane reactor at room temperature based on microfluidic control for the reduction of CO2 in extraterrestrial space. In this system, H2O was oxidized to O2 on the anode, while CO2 was reduced to C2H4 on the cathode. The highest Faraday efficiency (FE) for C2H4 was 72.7%, with a single-pass carbon efficiency toward C2H4 (SPCE-C2H4) of 4.64%. In addition, a microfluidic control technique was adopted to overcome the influence of the microgravity environment. The study may provide a solution for the long-term continuous oxygen supply during the process of space exploration.
