2021, 41(1): 22-33. doi: 10.11728/cjss2021.01.022
Abstract:
Surface morphology and target characteristics are two important problems in remote sensing. Surface morphology is a geometric problem and the aim of photogrammetry. Target characteristics are not only a physical and chemical problem, but also an important problem to be solved in the development of hyperspectral remote sensing. After decades of development, hyperspectral remote sensing technology has made great progress, from data acquisition, processing to application. As a new and young technology involving multiple disciplines, hyperspectral remote sensing development is a demand-oriented process in which the demand is constantly explored. Especially, the hyperspectral imager is the only tool to obtain hyperspectral data, and its development is very important for the development of hyperspectral remote sensing. In the paper, the feature and application of different types of hyperspectral imagers are analyzed, and some conclusions of hyperspectral imagers in recent 40 years are obtained. Combined with the current development status of hyperspectral imager, the future development trend of hyperspectral imager, especially the development of key indices and technology, is prospected to provide some ideas for the follow-up research in this field, and also to provide a reference for the related remote sensing satellite missions.

ZHANG Zexu, LI Ruixue
2021, 41(1): 118-128. doi: 10.11728/cjss2021.01.118
Abstract:
The mission of a space station that is known as the big platform of near-earth space is to enable long-term flight to explore space. As the ever-increasing number of on-orbit missions, it is a challenge to manage an effective on-orbit project. With the deep integration of artificial intelligence and space technology, the on-orbit operation of a space station has gradually developed to be intelligent. Therefore, the intelligent operation of spacecraft has become an inevitable trend. This paper focuses on the development of on-orbit intellectualization at the International Space Station (ISS) and the application of artificial intelligence technology in its health management, mission planning and scheduling, mission operation and human-computer interaction. It is hoped that the research will contribute to the intelligent on-orbit operation in China.

2021, 41(1): 129-132. doi: 10.11728/cjss2021.01.129
Abstract:
The exploration for extraterrestrial life is one of the most important targets of deep space exploration. The successful launch of China's first Mars probe “Tianwen-1” has started the scientific exploration about the surface morphology and life signs of Mars. As the most similar planet to the earth in the solar system, Mars brings human being endless reverie. Is there life on Mars? Can human beings immigrate to Mars in the future? Phosphorus, one of the important elements for life, plays an irreplaceable role in the whole evolution of life. Phosphate can be used as a potential biomarker to provide new ideas and clues for life exploration on Mars.

LU Huizhi, HUA Yuejin
2021, 41(1): 133-140. doi: 10.11728/cjss2021.01.133
Abstract:
Ionizing radiation exists widely in Earth and space, causing DNA damage and leading to mutation and even cell death. DNA damage response is essential for maintaining the integrity of genome. Deinococcus radiodurans is one of the model organisms for studying DNA damage repair due to its extraordinary DNA repair ability. PprI-DdrO system is a distinct and efficient damage response pathway in Deinococcus, in which PprI acts as an important switch regulating DNA damage response genes by cleavage of DdrO. This review discusses the research progresses of PprI from aspects of function, structure, activation mechanisms and applications.
Mirror-image Biological Molecules
CHEN Ji, ZHU Ting
2021, 41(1): 141-144. doi: 10.11728/cjss2021.01.141
Abstract:
The homochirality of biological molecules is a hallmark of all terrestrial life. Whether life's dependence on D-ribose nucleic acids and L-amino acids was required for the origins of life, or merely a chance event on prebiotic Earth remains unclear. Despite the challenges in elucidating the cause for homochirality, accumulating evidence suggests the possibility of synthesizing mirror-image life based on L-ribose nucleic acids and D-amino acids. Here we briefly summarize the recent findings in mirror-image biology and discuss the prospects of building mirror-image life in the laboratory using newly developed mirror-image molecular tools.
Time in Space:Advances in the Study of Circadian Rhythms under Microgravity
GUO Jinhu, GAN Xihui, MA Huan
2021, 41(1): 145-157. doi: 10.11728/cjss2021.01.145
Abstract:
Circadian clocks, derived from long-term evolution, are endogenous mechanisms which endow the organisms to adapt to the daily cycling environment on Earth. At the molecular level, circadian clocks are controlled by a series of clock genes and other clock associated regulators. At the tissue level, circadian systems are composed of master and peripheral clocks. Circadian clocks affect physiology, cognition and behavior of almost all organisms, which dictate their adaptability to the environment. Space environmental factors, e.g., microgravity, radiation, lighting condition and social factors, dramatically differ from those on the Earth, which may lead to impacts on circadian rhythms. Therefore, circadian clock needs to be considered in the study of space life sciences. Misalignment in circadian rhythms leads to sleep disorder and affects the skeleton-muscular system, neural system, cardio-vascular system, endocrine system, and so on, and decreases the performance of astronauts. Circadian clock will be a critical factor in future space life research and in study of astronaut health and performance.
Molecular Simulation Research on Metabolic Origin and Evolution

2021, 41(1): 158-166. doi: 10.11728/cjss2021.01.158
Abstract:
Metabolism provides the material and energy basis for life and played important roles in the origin and evolution of life. However, due to the lack of fossil evidence, significant issues such as the origin of metabolism and the molecular mechanisms of metabolism affecting evolution have yet to be resolved. In recent years, the emergence of molecular simulation methods such as network expansion algorithms provides new solutions to the above issues. This article will review recent molecular simulation studies on the origin and evolution of metabolism, with a view to providing new ideas for research in related fields.
