Livestreamed by China Media Group, the SZ-13 crew gave a 41 min science lecture on 23 March at 16:00 BJT from aboard the Tiangong space station. Millions of students across China and a worldwide audience watched the taikonauts demonstrating unique physical phenomena in the orbiting spacecraft. The crew conducted 4 experiments to demonstrate physical phenomena only possible in microgravity, including liquid crystallisation and a water bridge. Hundreds of students in Beijing, Lhasa (Tibet autonomous region) and Urumqi (Xinjiang Uygur autonomous region) watched the event at "ground class venues".

CNSA released images with 0.5 m resolution taken by the cameras on TW-1 orbiter, showing dust storms on the surface of the planet. Track marks left by the Zhurong rover can be seen in the pictures. The orbiter is operational since 609 days. Zhurong also relayed selfies from Mars. Compared with the images taken shortly after it landed on the planet, the new photos showed a layer of dust accumulated on its surface. Chinese scientists have specially designed the rover's solar panels to offset the power generation efficiency decline caused by dust coverage.

On 21 March, CASC completed a 100 s test fire of its high-thrust oxyhydrogen engine for the CZ-5 rocket, which will launch the space station lab module Mengtian. The engine is now ready for final assembly into the rocket. Designed for the core stage of the Long March-5 series carrier rockets, the engine is the most advanced cryogenic liquid rocket engine ever in China. There will be more than 20 experimental tasks that the rocket engine will undergo to test its performance further.

On 20 March, the construction China's first subway Beidou satellite navigation system started. It will be installed along the 30 km Beijing Capital International Airport line and 5 stations. It is expected to be completed by the end of this year.
The subway Beidou positioning system will improve the positioning accuracy of subway stations, which can be used not only for vehicle scheduling, passenger organization and emergency disposal, but also allow commuters to use cell phone maps to access navigation and positioning in subway stations through three-dimensional navigation.
