In 1975 the Soviet Union performed two manned flights on board the orbital station Salyut 4. The first mission of 30 days was flown by A. A. Gubarev (Commander) and G. M. Grechko (Flight Engineer) and the second mission of 63 days by P.I. Klimuk (Commander) and V.I. Sevastyanov (Flight Engineer). The present paper gives preliminary data on the general health and cardiovascular investigations of the crew members during and after flight. The clinical and physiological examinations of the cosmonauts showed that the work-rest cycles and counter-measures used helped to maintain their good health and high performance in flight, to alleviate adverse reactions and to facilitate readaptation post-flight. Medical results of the post-flight investigations revealed no changes that may detract from further increasing the duration of manned space missions.

Space agriculture, pivotal for sustainable extraterrestrial missions, requires plants that can adapt to altered gravitational conditions. This study delves into the adaptive responses to altered gravity of Wolffia globosa, an aquatic plant known for its rapid growth and high nutritional value. The research aimed to analyse the effect of simulated microgravity and hypergravity on relative growth rate (RGR), morphological characteristics, protein content, and the correlation between plant size and growth rate of Wolffia globosa.

Perinatal stem cells have prominent applications in cell therapy and regenerative medicine. Among them, human Wharton's jelly mesenchymal stem/stromal cells (hWJMSCs) and human amniotic epithelial stem cells (hAESCs) have been widely used. However, the distinction in the therapeutic potential of hWJMSCs and hAESCs is poorly understood.

Article Synopsis
- - NASA is planning to resume manned deep space missions, starting with the Moon and then Mars, and is investigating the potential health impacts of space radiation on astronauts during these long missions.
- - Research indicates that astronauts might experience significant impairments in cognitive functions, particularly in advanced executive skills, and these effects could vary based on their previous space exposure.
- - A study on rats found that after being re-exposed to space radiation, their ability to perform attentional set shifting tasks significantly declined, showing that prior radiation exposure alters cognitive impairments compared to animals that have never been exposed.

In the past decades, China has made significant progress on space life science research. Since completing the construction of the China Space Station (CSS) at the end of 2022, space life science research in China has entered a new era. Through carrying out numerous experiments on space life sciences, space medicine, and space agriculture conducted aboard the Shenzhou series, the CSS, and ground-based space environment simulation platforms, Chinese scientists have uncovered the effects of the space environment on the physiological and molecular mechanisms of live organisms.

This paper is devoted to the issue of using laser (lidar) sensing to determine wind speed and direction when solving practical problems during the analysis of meteorological conditions in the area around spaceports. This issue is relevant both for making decisions on the possibility of a safe launch of a launch vehicle and for conducting search and rescue operations using groups of manned and unmanned aerial vehicles. Based on numerical and experimental modeling, it is shown that lidars provide highly accurate measurements of wind speed profiles and allow for the determination of weak wind shear in vertical and horizontal directions.
