Shenzhou-19 crew perform work on extraterrestrial survival technology

The Shenzhou-19 crew on board China's space station has performed work related to experiments on the technology of artificial photosynthesis for extraterrestrial survival.

The crew used sampling cans to collect samples of reactants inside relevant devices and stored the samples to be brought down to the earth.

The technology, which simulates the natural photosynthesis of green plants through physical and chemical methods, utilizes carbon dioxide resources in confined spaces and extraterrestrial atmospheres in situ to produce oxygen and carbon-containing fuels. It is expected to provide important technical support for human survival and exploration in outer space in the future.

In the field of microgravity physics science, the crew disassembled solid-liquid mesoscopic experiment units in fluid physics experiment cabinet and installed experimental sample trays.

They also cleaned non-container experimental chambers, replaced experimental samples and maintained axis mechanisms and electrodes.

Last week, the crew also participated in a number of in-orbit training programs.

Rendezvous and docking is one of the professional and technical training programs for astronauts during their stay in the space. The crew used the metacognitive training system to complete trainings on image recognition under different initial conditions.

They also carried out medical rescue exercises, and emergency evacuation in the event of fire in space station.

Regarding equipment inspection and maintenance, the crew replaced circulation pumps of fluid loop system for space applications as planned, amongst other tasks.

The fluid loop system for space applications serves as a crucial mechanism within a space station for controlling and regulating the temperature of application system payloads, which ensures the smooth space science experiments.

The first widespread heavy rainfall China has experienced this year has triggered emergency responses across the country.

The National Meteorological Center (NMC) said the heavy rain is set to intensify throughout Saturday night to Sunday.

Level-IV flood control emergency responses were activated at 12:00 on Saturday for central China's Hubei Province and the southwestern Chongqing Municipality, while responses at the same level were maintained for the southern province of Guangdong and the southwestern province of Guizhou.

On early Saturday, heavy rain hit Guizhou's Zhenning Bouyei and Miao Autonomous County, with rainfall in some regions in the county exceeding 50 millimeters,

Trees toppled over on some roads in Zhenning, as thunderstorms and high winds swept the city.

Local authorities immediately launched emergency responses including hazard inspections and road obstacle clearance.

Continuing rainfalls in Guigang City in south China's Guangxi Zhuang Autonomous Region caused extensive flooding in major streets.

With the help of traffic control and flood drainage, the situation on the city's roads has returned to normal.

In Chongyi County, in east China's Jiangxi Province, persistent rain has flooded farmlands and triggered landslides on some roads.

Swift responses were launched to clear debris and reopen roads and traffic has started flowing again.
