Abstract
The Earth 2.0 (ET) mission is a next-generation Chinese space mission to detect thousands of Earth-sized planets, including habitable Earth-like planets orbiting solar type stars (Earth 2.0s), cold low-mass planets, and free floating planets. The ET mission will enter its Phase C study in 2026. During the Phase B study, detailed design and optimization of the spacecraft system were carried out, and several key aspects were updated to better fulfill the scientific requirements. In particular, the pointing stability requirement has been increased by more than one order of magnitude. This paper presents the progress in the ET spacecraft system design, covering the overall configuration, pointing stability control, scientific data download, and other aspects.

Innovation Academy for Microsatellites (China)
Kun Chen holds a Ph.D. in Instrument Science and Technology from Tianjin University. After completing his degree, he joined the Innovation Academy for Microsatellites, Chinese Academy of Sciences, where he has contributed to several key space science missions, including the ET, SVOM, Taiji-1, and STU-2 projects. He currently serves as the Deputy Chief Designer of the ET spacecraft.
His research is centered on advancing the design of scientific spacecrafts, with an emphasis on enhancing the efficiency of space-based exploration. This involves the full-cycle development of satellite systems, from mission analysis and conceptual spacecraft design to system integration and engineering implementation.
