Summary: This article describes the use of a cross-calibration method to calibrate the ZY1-02D hyperspectral imager, as the laboratory and vicarious calibration methods were not accurate after the satellite launch. By comparing with other calibration methods and conducting validation experiments, it is shown that the cross-calibration provides high-accuracy and stable radiation performance, and it is applicable to different ground features.

Summary: The study introduces a method to enhance signal-to-noise ratio in optical imaging using quantum techniques. By utilizing a supersensitive phase imager that operates over a large field of view, quantum-enhanced imaging of birefringent and nonbirefringent phase samples was demonstrated, with potential biomedical applications shown through imaging a protein microarray sample. The technology is scalable to high-resolution images and represents a significant advancement in practical quantum-enhanced imaging.

Summary: In this work, we present a versatile interference contrast imaging technique that achieves high phase sensitivity and a large field-of-view. This is achieved through the use of a self-imaging non-resonant cavity and a specially designed single-photon camera. The technique allows for multi-round measurements and reduces measurement noise through novel data processing. The results demonstrate a significant improvement in phase measurement noise and show good agreement with theoretical predictions. The technique is easy to use and has important applications in low light conditions for biological or photo-sensitive samples.

Summary: This paper investigates optimal solutions for a transfer from a parking orbit around the Moon to a halo orbit around L-2 of the Earth-Moon system. The transfers are executed by applying a single maneuver and exploiting the stable invariant manifold. The problem is solved using a nonlinear programming method, and the results show the feasibility of this kind of transfer with low Delta V and suitable times of flight.

Summary: Hyperostosis in taxonomically related species, Atlantic Moonfish Selene setapinnis and Lookdown Selene vomer, manifests and develops differently. Radiographic images showed that hyperostosis occurred in 65.22% of S. setapinnis specimens in three different skeletal regions, while all S. vomer specimens had hyperostosis in four regions. The affected regions differed between the two species, except for the cleithrum. The occurrence and development of hyperostotic bones were related to sexual maturity.

Summary: The original hypothesis of ice in lunar polar cold traps, claiming the concentration of meteoritic water through exospheric lateral transport, has been proven false. Solar wind sputter is proposed as the main process for removing meteoritic water from the lunar regolith. While past impulsive exospheric events are still possible, this study sets a constraint on the modern day water cycling.

Summary: Efforts are being made in Asia to reduce methane emissions, with a focus on accurate quantification of the region's CH4 budgets. This study provides top-down estimates of CH4 emissions in Asia from 2009 to 2018, showing significant emission growth in East Asia and decreasing emissions in South Asia. Climate variability plays a key role in interannual variability of CH4 flux, with Southern Asia being particularly affected.

Summary: Research indicates that the subsurface material of asteroid Ryugu is more hydrated than its surface, and has experienced alteration processes that can be traced back to its parent body. Observations using near-infrared spectrometer show that the subsurface material underwent heating above 300 degrees C, similar to the surface, supporting the hypothesis that primary thermal alteration occurred on Ryugu's parent body.

Summary: The study presented emissions data of open biomass burning in Northeast China from 2001 to 2017, with crop residue burning contributing the most to the total emissions. Heilongjiang Province was the largest emitter of CO2, with forest fires and grassland fires also influencing CO2 emissions. Emissions showed significant interannual variability, peaking in 2003 and 2008.

Summary: Planetesimals in the early stage of planetary formation are thought to have been porous aggregates of dust, with boulders on the surface of asteroid (162173) Ryugu found to have an average porosity of 30-50%, higher than meteorites but lower than cometary nuclei. High-resolution thermal and optical imaging revealed boulders with over 70% porosity at the bottom of small craters on Ryugu, indicating they may be the least processed material on the asteroid and remnants of porous planetesimals.

Summary: The dramatic increase in natural gas use in China as a substitute for coal has helped reduce CO2 emissions and air pollution. However, this climate mitigation benefit is offset by methane leakage into the atmosphere. Research estimates methane emissions from 2010 to 2018 in four regions of China and finds that the northeast region contributes the most to the overall methane emission growth rate, mainly due to the growth in natural gas use. The study highlights the detectable impact of increasing natural gas use on atmospheric methane observations and calls for methane emission reductions throughout the gas supply chain, as well as the promotion of low emission end-use facilities.

Summary: GOSAT-GW is a Japanese Earth observation satellite that aims to monitor global greenhouse gases and air pollutants. One of its key instruments, TANSO-3, is responsible for validating nationwide greenhouse gas emissions and detecting emissions from large sources. TANSO-3 data will also be used for identifying point sources using fossil fuels and their plumes.
