The second lesson of "Tiangong Classroom" was a complete success!
At 15:44 on March 23, 2022, the second lesson of "Tiangong Classroom" was held on the China Space Station, and "Space Teachers" Zhai Zhigang, Wang Yaping and Ye Guangfu gave another wonderful space science popularization class.
In the about 45-minute lecture, Zhai Zhigang, Wang Yaping and Ye Guangfu cooperated with each other to vividly demonstrate the space "ice and snow" experiment, the liquid bridge demonstration experiment, the water and oil separation experiment, and the space parabolic experiment in the microgravity environment, explained the scientific principles behind the experimental phenomena in a simple and simple way, and showed some space science facilities and introduced the work and life on the space station. During the lecture, the astronauts interacted with the teachers and students of the ground classroom through video calls.
Tianwen-1 transmitted high-resolution images of the Mars patrol area
In mid-March, the near-fire point of the Tianwen-1 orbiter once again passed over the rover inspection area, and a 0.5-meter resolution image of the "Zhurong" inspection area was taken, and the driving route of the "Zhurong" rover in the picture was clearly recognizable. As of March 24, 2022, the "Zhurong" rover has worked on the surface of Mars for 306 Martian days, with a total of 1784 meters, and the "Tianwen-1" orbiter has been in orbit for 609 days, 277 million kilometers away from the earth, and the two are operating normally.
