Interesting, it seems that China has settled on hypergolic staged combustion engine for lunar lander after investigating both LOX/Kerosine and LOX/CH4.Mr. Wang Meng (王猛) has won the 2022 Aerospace Propulsion Award for his work on the 80kN engine of the future manned lunar lander. The engine apparently took only 14-months to go from detailed design to full-system test run.
This news also filled a hole in the "8 years 9 engines" roadmap according to

Zhejiang University, University of Hong Kong, Hong Kong Polytechnic University, and United Arab Emirates University to develop and launch a gravitational wave observatory.
In recent years, gravitational wave detection has become a new window and means for human beings to observe the universe. Countries are scrambling to move the gravitational wave observatory into space and launch gravitational wave detection satellites.
From May 16 to 17, Zhejiang University, together with the University of Hong Kong, the Hong Kong Polytechnic University, the United Arab Emirates University and other units, held a seminar and signed a cooperation agreement at the Yuquan Campus of Zhejiang University. The participants plan to jointly invest resources to develop and launch the gravitational wave observatory - 6U CubeSat satellite. It is equipped with a 0.1-10 MeV energy range detector to detect cosmic gamma rays.
According to Professor Wang Huiquan, deputy director of the Microsatellite Research Center of Zhejiang University, compared with ground-based exploration, the frequency band of space gravitational wave detection is lower and has richer wave sources. In August 2019, China's first space gravitational wave detection technology experimental satellite "Taiji-1" was successfully launched into orbit.
MeV is a unit of energy, and 1MeV is 1 million electron volts. In space, gamma rays in the 0.1-10MeV energy range carry a large amount of astronomical information that has not been observed before, which can help scientists better understand the phenomenon of gravitational wave sources and cosmic singularities, and lay the foundation for subsequent large-scale MeV ray observatory missions to help human beings. Exploration of the universe. Wang Huiquan told Chao News that the satellite is expected to be launched into orbit in 2025.
In September 2015, the LIGO research group for ground-based laser interference gravitational wave detection directly detected gravitational waves for the first time in the history of human science. The results were announced in February 2016, causing a global sensation. Kip Thorne and Barry Barish, the scientists who conceived and designed LIGO, were awarded the 2017 Nobel Prize in Physics. Since then, space gravitational wave detection has become one of the competitive focuses of astronomical exploration at home and abroad.
It is reported that this meeting is supported by the Sky Exploration Gathering Plan of Zhejiang University, which strives to promote the convergence of superior disciplines of Zhejiang University such as aerospace, mechanics, information, control, machinery, energy, medicine, etc., and promotes major breakthroughs in original achievements.
