The MSS-1 (Macau Science Satellites-1) twin satellites were successfully launched on 21 May 2023 into a nearly circular low-inclination (41 degree) orbit at an altitude of about 450 km: Satellite A carries a payload of high-precision magnetometers to accurately measure Earth's magnetic field while Satellite B is equipped with other sensors such as a solar X-ray instrument to obtain space environmental data. The MSS-2 twin satellites, marked by strongly eccentric polar orbits forming the MSS constellation of geomagnetic survey satellites, are scheduled to launch in the year of 2028. We report using the geomagnetic field accurately measured by the MSS-1 geomagnetic satellite to probe the convection-driven geodynamo and the spatial-temporal structure of Earth's oceans movement.

Professor Keke ZHANG is a Chair Professor, Associate Vice President of Macau University of Science and Technology, and Director of the Macau Institute of Space Technology and Application. He serves as the Chief Scientist and Chief Designer of the Science and Application System for the "Macau Science Satellite-1". His main research areas include Earth and space sciences, as well as geomagnetic theory and its applications. Professor Zhang is a Fellow of American Geophysical Union (USA) and Royal Astronomical Society (UK). He received the National Science Fund for Distinguished Young Scholars Fund Award in 2000, the Royal Astronomical Society Achievement Award in 2013, the First Prize of the Macau SAR Government Science and Technology Award in 2020, and was listed among the top 0.5% of global scientists in 2024. In 2025, he was awarded the Shen Kuo Award, the highest scientific honor from the International Association of Geomagnetism and Aeronomy (IAGA), in recognition of his contributions to geodynamo theory, core wave studies, and the Macau science satellite mission—marking the first time an Asian scientist has received this prestigious award.
