According to CoinMeta, the main objectives of China's Tianwen-4 mission are to achieve orbiting Jupiter, orbiting Ganymede (Jupiter's largest moon), and conducting landing missions, with the aim of deepening scientific research on the Jupiter system. On November 13th, the Lunar and Space Exploration Engineering Center issued a notice to solicit proposals for the development of payloads for the Tianwen-4 mission, and the best design proposals and responsible units will be selected through a competitive process. According to the submission guidelines, the payloads for the Tianwen-4 orbiter include a Soft X-ray Spectrometer, a Far Ultraviolet Imager, a Jupiter Magnetosphere Particle Detector, and nine other engineering development tasks. For example, the Soft X-ray Spectrometer is required to study the characteristics of Jupiter's auroras across different energy ranges and the processes by which they are influenced by the solar wind and Io (one of Jupiter's moons); the Far Ultraviolet Imager is capable of capturing far ultraviolet images of Jupiter's auroras and Io's plasma ring for related research; the Laser Altimeter needs to have the capability to probe icy moons such as Ganymede. The payloads for the Tianwen-4 lander include a Surface Composition Analyzer and a Surface Magnetic Field Detector, which will support tasks such as conducting Raman spectroscopy of the surface in the landing area of Ganymede, determining the types of surface materials, and in-situ detection of the surface magnetic field.
