«Shenzhou — 10» returned to Earth

On the morning of June 26 after a 15-day flight the crew of a Chinese spacecraft «Shenzhou-10» of three people — not Haisheng commander, operator and laboratory Zhang Xiaoguang Wang Yaping — safely returned to Earth. The return capsule of the ship at 8 7 local time (0:07 UTC) successfully landed in a predetermined area of ​​Inner Mongolia Autonomous Region.

In the ten years since 2003, when the first space flight of China representative Yang Liwei in space was visited by only 10 taikonaut. Wang Yaping has become the second Chinese woman in orbit. She was one of two women who were outside the atmosphere June 16, 2013, to commemorate the 50th anniversary of the historic flight of the first woman cosmonaut Valentina Tereshkova. The second was Karen Nyberg (Karen Nyberg), took part in the ISS 36/37.

Flying «Shenzhou 10» is also notable for the fact that on 20 June Wang Yaping held a school lesson, while on board the orbital module «Tiangong-1» at an altitude of 340 km. Taykonavtka via video children read a lecture on the laws of physics in weightlessness and showed several experiments. Video calling has been set to one of the classrooms of the People’s University in Beijing, which gathered 330 students from all over China.

The lecture was broadcast as Chinese TV. More than 60 million students and their teachers from more than 80 thousand. Chinese secondary schools across the country watched the space physics lesson on the air.

The class started at 10 minutes 4 Beijing time and lasted 51 minutes. Initially, Wang Yaping told that the space can not measure its mass using conventional weights, and showed a special device for this purpose, the principle of action is based on Newton’s second law. «Cosmic teacher» helped her male colleagues, in orbit. For example, simple things — top, ball and water — they demonstrated how to operate the basic laws of physics of weightlessness. The students wanted to know what water use taikonaut: brought from Earth, or stored on the station. Not Haisheng said that a small supply of water they brought with them, but the station is and install recycling. Wang Yaping also shows how weightlessness changes the behavior of the liquid. Asked what interesting taikonaut seen in space, she said, «The stars that we see is much brighter and they do not flicker in a vacuum. The sky is not blue, as we used to, and black. And every day we are 16 times to watch the sunrise. After all, our station flies around the Earth in 90 minutes. » At the end of the lecture the children were asked a few questions about life on board the orbital complex.

Speech Wang Yaping was not the first lesson drawn from the cosmos. The first «cosmic teacher» was to be an American Christa McAuliffe (Christa McAuliffe). However, during the collapse of the space shuttle Challenger in January 1986 she was killed along with his crew. Lessons conducted in 2007, another American — Barbara Morgan (Barbara Morgan), the former understudy Christa McAuliffe. She flew aboard the shuttle Endeavour and visited the International Space Station.

The module «Tiangong-1» was launched into Earth orbit in November 2011. He is a prototype of China’s long-term station. Successful completion of all tasks during his joint mission with the spacecraft «Shenzhou-10» marks the entry of China in the era of the construction of manned orbital stations. Since September 2011, China sent into orbit three spacecraft — «Shenzhou-8», «Shenzhou 9» and «Shenzhou-10.» During their flights have been fulfilled the most important technologies, including docked with the orbital unit taikonaut and out into space.

By 2015, under the program of construction of a manned space station, China will complete the development of two new types of launch vehicle — «Long March-5» and «Long March-7.» The first of them will have a capacity of over 20 tons and is designed to orbit the station itself. And the second (with a capacity of more than 13 tons) — to deliver her cargo and crew. By 2015 China plans to send into space lab «Tiangong-2», by 2018 will be launched pilot base module of the future space station, and in 2020 the construction of China’s manned space station will be completed.
