In a recent study published in Space: Science & Technology, a research team from Simon Fraser University and the University of Calgary, for the first time, adopted the brain vital signs framework to monitor cognitive and neurophysiological function in astronauts participating in a 17‑day mission to the International Space Station.

In a recent study published in Space: Science & Technology, the team led by Researcher Wang Xiaowei from the China Academy of Launch Vehicle Technology proposed a novel approach to detonation defense technology for large‑sized near‑Earth asteroids.

Recently, a study published in Space: Science & Technology by researchers from Capital Medical University in collaboration with the National Space Science Center systematically investigated the cerebrovascular coupling response mechanisms during early simulated microgravity by integrating Doppler ultrasound with three-dimensional pseudo-continuous arterial spin labeling magnetic resonance perfusion imaging.

In recent years, rapidly advanced space technology has resulted in a growing number of objects in orbit, including both operational and decommissioned spacecraft, as well as space debris, which pose potential threats to China’s on-orbit spacecraft. To ensure the safe operation of spacecraft in near-Earth and high-orbit environments, a key research focus in the field of space technology is the high-resolution and high-accuracy detection and perception of environmental objects under strong backlight conditions. Such capabilities are critical for providing timely early warnings to on-orbit spacecraft. However, a plethora of studies have demonstrated marked challenges in imaging dark and weak targets under strong light backgrounds. It is essential to analyze the challenges of current backlight imaging technologies, summarize the working principles of existing backlight detection methods, and explore future development trends.

iant planet in our solar system. Currently, numerous engineers are engaged in efforts to deploy probes into the Jovian system, and some key technical research studies are also carried out for future Jovian system exploration missions. However, capturing into another planet’s system is a costly process, particularly for the Jovian system. The presence of 4 Galilean moons renders the gravity-assist technique a highly effective means of modifying the velocity of probes relative to Jupiter. However, if a Jovian moon is expected to be visited, the perijove of the spacecraft must be lower than the orbital radius of the moon. There are disadvantages to capturing with a low perijove. Firstly, the spacecraft is severely affected by the strong radiation of Jupiter, which is harmful to the electronic components on the spacecraft when it gets close to Jupiter. Secondly, an amount of fuel is consumed to raise the perijove to satisfy the requirements of subsequent objectives. In order to alleviate the disadvantages of low-perijove capture, one solution is to raise the perijove more efficiently by leveraging the solar gravity perturbation (SGP).
