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.

African Space Agency to Be Inaugurated at 4th NewSpace Africa Conference in Cairo, Egypt
The 4th NewSpace Africa Conference is being held in Cairo, Egypt on April 21-24 with theme Empowering Africa’s Economy through Space-driven Innovation and hosted by the African Space Agency (AfSA), Egyptian Space Agency, and Space in Africa. AfSA, although officially formed and ‘inaugurated’ in 2023, will again be inaugurated during the conference by the African Union (AU). There will be 65 countries represented by 500+ delegates, 50 speakers, 40 exhibitors and 35 sponsors involving space agencies, commercial companies, academia and government. Opening the Conference will be Sherif Sedky (Egyptian Space Agency CEO), Tidiane Ouattara (African Space Agency President), and Temidayo Oniosun (Space in Africa Managing Director). ‘The Future and Perspectives of the African Outer Space Programme’ Keynote is by International Space University Chancellor Valanathan Munsami. ‘Space for All: Advancing Africa’s Influence in International Space Governance’ session describes “Africa’s evolving position within the rapidly expanding global space economy, projected to reach USD 1 trillion in the coming decade.” There are 54 United Nations recognized countries in Africa–18 of them have national space agencies. Egypt, South Africa and Senegal are part of the International Lunar Research Station, while Angola, Nigeria, and Rwanda signed the Artemis Accords. Space Exploration and Research Agency, a USA company, facilitated an agreement to send the first Nigerian citizen to space aboard a future Blue Origin New Shepard flight.
