Tiangong-2 mission has caught the attention of people at home and abroad. A Brazilian aerospace expert told CCTV that the launch of the Tiangong-2 will not only benefit China but also the whole world.

He said many experiments to be conducted during the mission are unprecedented, and will give us more insights into space. He added that China's achievements in space exploration are a demonstration of the country's economic success.

"I think the successful launch of the Tiangong-2 is a very important moment in aerospace history. Currently, only a few countries have space lab technology. China's progress in this field will offer more possibilities for future space exploration," said Prof. Annibal Hetem Junior, Federal University of ABC, Brazil.
