India is hosting this year's G20 summit on September 9 and 10. Global economic, technological and multilateral collaboration are some of the hot topics. India's remarkable achievements in space, particularly its recent lunar and solar exploration missions have captured global attention. 

But, what is the reason behind the country's successful lunar mission? How will this mission inspire other developing countries' space explorations? CGTN reporter Wu Lei invited Srijan Pal Singh, a scientist, entrepreneur and advisor of the 11th Indian President Abdul Kalam; Dr. Bernard Foing, director of the International Lunar Exploration Working Group; Dr. Yang Yuguang, vice chair of IAF Space Transportation Committee for this discussion.
