China to Launch Shenzhou, Holds 2nd Lunar Samples Forum and National Space Day During China Space Conference
Tiangong Space Station Taikonauts are planning to welcome Shenzhou 20 three-member crew subsequent to their launch from Jiuquan aboard a Long March 2F rocket. Similar to the current 3-member crew, they expect a stay of about 180 days. April 22-23 will assemble scientists in Shanghai for presentation of the latest research into Moon regolith samples returned via the Chang’E-5 and Chang’E-6 missions. Also in Shanghai, Apr 23-26, ~1,200 guests from 40+ countries are expected for the China Space Conference. Goals include not only technological innovation but international cooperation and exchanges. Conference activities include forums, exhibitions, roadshows and cultural experiences. One of the forums is on Advanced Aerospace Materials, Structures and Manufacturing Technologies, and one could imaging a report on the research and development of the mag-lev launch system being accomplished in China by private aerospace company Galactic Energy, which would accelerate rockets to at least Mach 1 before ignition, saving approximately 87.54% of its fuel. Other Space Conference forums include space biology , space policy / law, and an International Forum on Commercial Space Industry. Over 400 related activities: science lectures and seminars, space knowledge competitions and the China Space Culture and Art Form will be held, particularly in celebration of April 24 as the Space Day of China, which marks the launch of its first satellite “Dongfanghong-1” on that day in 1970.
