Summary: This work compares four different image processing algorithms for the analysis of image data obtained during the Multiscale Boiling Experiment of ESA. The algorithms were developed by four research teams to detect bubble edges and calculate geometric features. The efficiency of each approach varies with the nature of measurement, and the benchmark dataset is published for further testing.

Summary: This study provides a comprehensive analysis of the International Space Station (ISS) surface microbiome, including microbial burden, prevalence of bacterial and fungal species, temporal and spatial changes in the microbiome and resistome, as well as the functional capabilities and microbial interactions of this unique built microbiome. The results show that the ISS surface microbiome is dominated by organisms associated with the human skin. The study also identifies antimicrobial resistance genes and assesses the functional potential of the microbiome.

Summary: Despite extensive research, the understanding of human health changes resulting from long-duration space flight is still limited. This study provides a compilation of data from 37 health studies, analyzing 517 parameters, to enhance our understanding of the effects of long-duration spaceflight on human health. The results suggest that there are significant physiological and biochemical changes during spaceflight, while the changes post-flight are minimal.

Summary: This study demonstrates the use of superconducting materials, specifically in a superconducting magnetic levitation magnetoelectric generator (SMMG), to harvest energy in dark environments. The SMMG converts mechanical impacts to electricity and operates at low temperatures. This technology is well-suited for powering sensors and communication devices in outer space, especially in places without sunlight.

Summary: This study predicts possible metabolic interactions in the ISS microbiome using a computational approach and sheds further light on its organization. The results show beneficial interactions between Klebsiella pneumoniae and Pantoea genus, and parasitic and amensalistic interactions between Klebsiella pneumoniae and Aspergillus and Penicillium species. Klebsiella pneumoniae has positive effects on the survival of other microorganisms, but may also have negative interactions with potential pathogens.

Summary: This study reports the genomic, proteomic, and metabolomic alterations in Aspergillus niger strain JSC-093350089 grown in a controlled experiment aboard the International Space Station (ISS). Results show that microgravity and enhanced irradiation triggered non-synonymous point mutations in specific regions of the genome, altered protein abundance, and changed the metabolite composition.

Summary: Three novel bacterial strains, IF7SW-B2(T), IIF1SW-B5, and IIF4SW-B5, belonging to the genus Methylobacterium, were isolated from the International Space Station (ISS). These strains are proposed to be a new species named Methylobacterium ajmalii based on genomic, phylogenetic, biochemical, and fatty acid analyses.

Summary: The study found that under different gravity conditions, Sphingomonas desiccabilis and Bacillus subtilis enhanced the leaching of vanadium by 184.92% to 283.22% compared to sterile controls. Gravity did not significantly affect the mean leaching rate, demonstrating the potential for biomining on Solar System objects.

Summary: In a space experiment, a roll of cotton cloth fixed on the International Space Station for over 10 years was returned to Earth in September 2019. By analyzing the elemental composition and radioactivity of the contaminated and clean fragments of the cloth, researchers found more chemical elements on the contaminated fragment and discussed possible sources of these elements.

Summary: This publication lays the foundation for the description of the Multiscale Boiling Experiment conducted on the International Space Station. The experiment investigates two-phase heat transfer during boiling processes by selectively igniting bubbles on a heated substrate using a short laser pulse. The study is significant for understanding the phenomena and has generated over 3000 datasets over an 11-month measurement period.

Summary: The rapid growth of China's national resources in the space domain may change the power gap with the United States in relevant international rulemaking. This article presents an analytical framework for identifying and comparing states' power resources critical to international rulemaking, and applies it to compare China and the US in the space domain. The article explores comparative advantages, consensus, differences, and cooperation possibilities of the two countries in specific international space rules. The framework has wider applications and contributes to research on space law, international legislation, and national power.

Summary: China should balance its own national interests and the common interests of the international community when engaging in international space cooperation, emphasizing the establishment of a space station through China-led cooperation. It should invite developed countries to participate to safeguard its own interests while also creating opportunities for developing countries to participate in order to safeguard the wider common interests of the international community.

Summary: This paper investigates the magnetic field data provided by the Astro Pi sensor onboard the International Space Station (ISS) and finds good agreement with the geomagnetic field model. The paper points out the difficulty of extracting the magnetic field contributed by ISS due to the ISS not being designed for magnetic field observations, but proposes an optimization procedure to overcome this issue. However, the accuracy of the results is currently limited by sensor performance and lack of attitude information, but can be improved by better sensors and data processing algorithms. The paper highlights the importance of the ISS in providing magnetic field data at low altitudes rarely reached by satellites for monitoring and modeling purposes.
