Tsinghua High School students participate in the first "Space Dream" youth Space Science and technology camp

From February 3 to 10, 2015, the Astronaut Center and Tsinghua University jointly held the first "Space Dream" youth Space Science and technology camp activity. Five students from Tsinghua High School Affiliated to Tsinghua University participated in the activity: Liang Ziqing, Liu Yuehan, Han Sanyue, Zhang Yifan, Senior 12, and Zuo Runze, junior 12。

2月3日，The opening ceremony was held at the Astronaut Center，Chen Shanguang, deputy chief designer of manned space engineering and director of the Key Laboratory of Human Factors Engineering, announced the official opening of the camp，Vice Chairman of China Association for Science and Technology Chen Zhangliang delivered a speech，Said the event will be of great significance to students pursuing their space dreams，Congratulations to the students who were able to participate in the event。Astronauts Wang Yaping and Liu Wang also came to meet with the students after the opening ceremony and took a group photo。

After the opening ceremony, experts from various departments held expert lectures for students, such as space suits and the challenges faced by human extraterrestrial survival guarantee, so that students had a deeper understanding of the relevant knowledge of manned space flight, and stimulated great interest in space exploration。Space suit lectures mainly focus on the classification, use, function, dangers to protect and limitations of space suits. Students carefully study the content of lectures, actively ask questions, and interact with experts on points of interest to themselves。

On February 4, the students visited the facilities such as the 1:1 simulation of the Shenzhou 10 orbital module and Tiangong-1 experiment module, the physical space suit, the environmental control and health protection laboratory and the weightlessness simulation tank。During the visit, experts explained the functional principles of each part of the space suit to the students;A series of processes from waste absorption to recycling in environmental control life protection system and the practical application of weightlessness principle in weightlessness simulation water tank。The students also experienced the weight of the 20K high space suit, which narrowed the distance between the students and the most advanced space technology, opened up the students' vision, and let the students have the spirit of in-depth exploration and pursuit of technical knowledge。

On February 5, the students experienced the rendezvous and docking simulator and the robotic arm simulator。After listening to the theoretical guidance, the practical operation of the simulated platform was carried out, and the target aircraft was docked by manually controlling the handle。In practice, from failure to success, students experience not only the joy of success at the moment, but also not only the in-depth understanding of the docking process between the spaceship and the target aircraft, but truly appreciate the distance between theory and practice, as well as the experience and knowledge mined through failure。The operation of the space robot arm also brought a lot of fun to the students，They think the technology is more like a computer game，In this simulation exercise，Students need to operate the handle to control the joint of the robot arm by observing the images of the robot arm in all directions on the computer to realize the end of the robot arm to reach the specified target position，It is required to have good spatial imagination ability and coordination control ability of hand and brain。

On the morning of February 6, the students came to Tsinghua University to visit the manned spaceflight related laboratories and understand the functional principles of the relevant equipment。In the afternoon, I went to the office of Professor Gao Yunfeng of Tsinghua University, and had a preliminary experience of the new learning mode. Under this mode, students could quickly turn their ideas into reality, which greatly stimulated their innovative thinking。

2月7～9日，Students began to design products autonomously in small groups under the model of CAME，In the process，Students combine knowledge from various subjects they have previously studied，The knowledge of various disciplines has been integrated，They also understand better and are able to apply what they have learned before，同时，In group work，The students demonstrated strong teamwork skills，And finally achieved good results。

On February 10, we returned to the Astronaut Center, and the students made a detailed report to the leaders and experts of the Astronaut Center with the gains, feelings and achievements of labor in these days, and won the recognition of the leaders and experts, and won the applause of the students themselves。
