[Aiming at Jupiter, the Tianwen-4 payload development plan is solicited] November 13th, the main goal of China’s Tianwen-4 mission is to achieve Jupiter orbit, Callisto orbit and landing detection, and deepen the scientific research of the Jupiter galaxy. On November 13, the Lunar Exploration and Aerospace Engineering Center issued a notice to launch a collection of payload development plans for the Tianwen-4 mission. The payload design plan and the responsible unit will be selected through competitive selection. According to the application guidelines, the payload of the Tianwen-4 orbiter includes 10 engineering development tasks such as a soft X-ray spectrometer, a far-ultraviolet imager, and a Jupiter magnetospheric particle detector. For example, the soft X-ray spectrometer must be able to support the completion of detection tasks such as studying the multi-energy segment auroral characteristics of Jupiter and the processes controlled by the solar wind and Io; the far-ultraviolet imager must be able to obtain far-ultraviolet images of Jupiter's aurora and Io's plasma ring and conduct related research; the laser altimeter needs to have the ability to detect icy satellites such as Callisto. The payload of the Tianwen-4 lander includes a surface composition analyzer and a surface magnetic field detector, which will support the completion of Raman spectrum detection of the surface of the Callisto landing area, acquisition of surface material composition types, and surface magnetic field in-place detection.
