Expert: The second Shenzhou-13 spacewalk is necessary to accumulate knowledge and EVA spacesuit experience
As Chinese astronauts prepare for a spacewalk from the country's space station, CGTN's Global Watch is joined by Professor Yang Yuguang from the China Aerospace Science and Industry Corporation. He is also the vice chair of IAF Space Transportation Committee. Professor Yang said that Sunday's spacewalk will be the fourth usage of EVA spacesuit.
