Core Viewpoint - The Chang'e 7 mission aims to explore the lunar south pole, specifically the Aitken Basin, with the goal of discovering water on the moon, potentially making China the first country to find lunar water [1][3]. Group 1: Chang'e 7 Mission Details - Chang'e 7 employs a "four instruments and one satellite" combination, including an orbiter, lander, rover, and relay satellite, to conduct close-range exploration of permanently shadowed craters on the moon [3]. - The mission will utilize an innovative flying device to conduct the first close-up investigation of the moon's shadowed areas, where scientists believe large amounts of water ice may be stored [3][4]. Group 2: Scientific Research and Experiments - Research is being conducted at Harbin Institute of Technology to simulate lunar conditions and create water ice from lunar regolith, utilizing a vacuum environment and extremely low temperatures [6][8]. - The equipment developed can generate a stable flow of water molecules, which, when in contact with cold regolith, can lead to the formation of water ice samples [8]. Group 3: Broader Space Exploration Initiatives - In addition to the Chang'e missions, China's "Tianwen" series of planetary exploration tasks are advancing, including missions to collect samples from near-Earth asteroids and return Martian samples to Earth [9][11]. - Future missions are planned for solar exploration, boundary exploration of the solar system, and Venus exploration, contributing to a comprehensive deep space exploration system [13].

Core Viewpoint - China successfully launched the Tianwen-2 probe on May 29, 2023, to explore asteroid 2016HO3 and comet 311P, marking a significant step in planetary exploration and sample collection [2][16]. Group 1: Mission Overview - The Tianwen-2 mission consists of two phases: the first phase (2025-2027) involves flying to and sampling the near-Earth asteroid 2016HO3, which is considered a potential source of primordial solar system information [5][16]. - The second phase (2028-2035) will focus on observing the main-belt comet 311P, which has characteristics of both comets and asteroids, to study its volatile components and formation [5][16]. Group 2: Future Missions - The Tianwen-3 mission is planned for launch around 2028, with a goal to return samples from Mars by 2031, including surface and subsurface samples weighing no less than 500 grams [6][16]. - Tianwen-4 is scheduled for around 2030, focusing on orbiting Jupiter and its moon Europa to investigate their spatial and internal structures [6][17]. Group 3: Scientific Goals - The primary scientific objectives of Tianwen-3 include searching for signs of extraterrestrial life, understanding the evolution of Mars' habitable environment, and studying its geological structure [8][12]. - The mission aims to clarify the distribution and evolution of water on Mars, as well as the mechanisms of atmospheric escape, which are crucial for understanding planetary habitability [10][12]. Group 4: Importance of Landing Site - The selection of landing sites for the Tianwen-3 mission is critical for achieving its scientific goals, requiring precise identification of high-value scientific locations that also meet engineering feasibility [12][18]. - The research team is employing methods similar to "mineral prediction" on Earth to evaluate potential landing sites on Mars, considering geological evolution, ancient climate, and water activity [13][18]. Group 5: Broader Context of Planetary Exploration - The exploration of Mars and other celestial bodies is part of a broader strategy to understand planetary habitability and the potential for extraterrestrial life, which is a significant focus of global scientific efforts [8][19]. - Following the Tianwen series, China plans to continue advancing its planetary exploration initiatives, including missions to Venus and the icy moons of the outer solar system [19][20].
