Allegedly, 36 healthy male participants lay on beds with their feet high and head low for 90 Days for a trial to create weightlessness that will make the way for Chinese astronauts’ long-duration stay in space. Li Yinghui—Deputy Chief Designer for China’s crewed space program—said the number of people concurrently participating in such a trial was a world record. The Earth Star-2 experiment was carried by the China Astronaut Research and Training Center and is grounding for China’s space station that is anticipated to be finished by 2022. When the body is supine for a long time, fluid moves to the chest and head, and the leg muscles and bones are less stimulated and active, comparable with the body alterations of astronauts in space owing to weightlessness, stated Li.
She added, “In the trial, we can analyze cardiovascular dysfunction, muscle atrophy, bone loss, endocrine disorders, and other medical issues under the conditions of lightness in space. This experiment can present scientific information on the impact of long-term lightness on the human body, and aid us in testing the efficiency of the protection measures for astronauts.” The volunteers were picked from over 400 candidates. Scientists conducted over 10,000 tests and assembled the data on basic physiological, bone, psychological evaluations, cardiovascular, and other indicators. The trial had three phases such as 15 Days of adjustment, 90 Days of bed rest, and 33 Days of revival, making a total of 138 Days. At present, the participants are in the revival period, said Li.
On a similar note, recently, China launched an innovative Earth observation satellite. In recent times, China launched Gaofen-7—Earth observation satellite—that will play a major role in land mapping and surveying, rural and urban construction and statistical investigation, as reported by the CNSA (China National Space Administration). The Gaofen-7 was developed on a Long March-4B rocket from the TSLC (Taiyuan Satellite Launch Center), Shanxi Province and is the country’s first civil-use optical broadcast three-dimensional mapping and surveying satellite that attains the sub-meter level, CNSA reported.
