On May 15, 2021, Tianwen-1 successfully landed in the Utopia Planitia of Mars, and its rover Zhurong began to carry out an in-situ science exploration of the Mars surface. To determine the location,driving direction, and exploration targets of the rover, it is necessary to provide decision support for the in-situ science exploration of the rover and ensure the achievement of the scientific objectives, which pose significant challenges to the ground science team. Based on the classical research on Lunar and planetary localization, navigation and exploration target selection, and the recent study of pan-location cartographic theory, a pan-location mapping method for an in-situ rover exploration is proposed. In addition, a panlocation reference system, mapping data model, and mapping method are designed to realize the localization and visualization of the landing platform, rover, and exploration targets. The mapping method has been successfully applied to the localization, navigation, and science exploration of the target selection involved in the in-situ exploration of the Zhurong rover. The results of this study not only provide vital support to the implementation of the Tianwen-1 mission; they can also be used as instructions for other future in-situ Lunar and planetary exploration missions.

This paper introduces a new method of small lunar craters’ automatic identification, using digital orthophoto map(DOM) data. The core of the approach is the fact that the lunar exploration DOM data reveal contrasting highlight and shadow characteristics of small craters under sunlight irradiation. This research effort combines image processing and mathematical modeling. Overall it proposes a new planetary data processing approach, to segment and extract the highlight and shadow regions of small craters,using the image gray frequency(IGF) statistical *** can also be applied to identify the coupling relationships between small craters’ shape and their relative features. This paper presents the highlight and shadow pair matching(HSPM) model which manages to perform highprecision automatic recognition of small lunar *** was performed using the DOM data of Chang’E-2(CE-2). The results have shown that the proposed method has a high level of successful detection rate. The proposed methodology that uses DOM data can complement the drawbacks of the digital elevation model(DEM) that has a relatively high false detection rate. A hybrid fusion model(FUM) that combines both DOM and DEM data, was carried out to simultaneously identify small, medium, and large-sized craters. It has been proven that the FUM generally shows stronger recognition ability compared to previous approaches and it can be adapted for high precision identification of craters on the whole lunar *** results meet the requirements for a reliable and accurate exploration of the Moon and the planets.
