Chinese astronauts on Thursday taught science lessons from the country’s under-construction space station. The lecture focused on physics, intended to explain how a weightless environment affects buoyancy, the motion of objects, and optics. Astronauts from five cities, including Beijing and the semi-autonomous region of Hong Kong, posed with questions about living conditions in space and were treated to a virtual tour of the station. The event was also open to the public via a livestream.
Wang Yaping, the only woman on the station, served as chief instructor, while Ye Guangfu assisted and Commander-in-Chief Zhai Zhigang served as the camera. Wang taught a similar lesson aboard one of China’s first experimental stations in 2013.

What happens when you dissolve a glowing tablet in a floating ball of water in space? Here is the answer to the first space lecture at Tiangong Space Station (CSS).

The trio arrived at the station in October for a six-month stay, charged with preparing the main Tianhe module for the arrival of two additional modules, named Mengtian and Ventian, before completion by the end of the following year.
Wang became the first Chinese woman to perform a spacewalk last month, when she and Zhai spent six hours outside the module to set up and test equipment with the station’s robotic service arm.
His Shenzhou-13 mission is China’s longest since it sent humans into space for the first time in 2003, becoming only the third country after Russia and the US to do so.

There are three permanent second crewmembers on the station, which when completed will weigh about 66 tons, much smaller than the International Space Station, which launched its first module in 1998 and weighed about 450 tons.
With equipment installed in preparation for the station’s expansion, the crew is assessing living conditions in the Tianhe module and conducting experiments in space medicine and other areas.
China’s space program was banned from the International Space Station, mainly because of US concerns over its intimate military ties.
China has also carried out crewed missions, and its lunar exploration program generated media buzz this week when its Yutu 2 rover sent back photos of what some have described as a “mysterious hut, but the most More likely only the rock of some sort.
The rover is the first to be placed on the little-explored far side of the Moon, while China’s Chang’e 5 probe returned lunar rocks to Earth last December for the first time since the 1970s. Meanwhile, a Chinese rover is searching for evidence of life on other Mars.
The program has also raised controversy. In October, China’s foreign ministry rejected a report that China had tested a hypersonic missile two months earlier, saying it had only tested whether a new spacecraft could be reused. Is.
China is also reportedly developing a highly secretive space plane.
