Planetary science is a new interdisciplinary subject. With the successful realization of the lunar "Chang'e" series of missions and the Mars "Tianwen No. 1" mission, it shows that my country's deep space exploration has been at the forefront of the world and has obtained massive scientific data on the moon and Mars. In order to tap the application potential of planetary science data and obtain more scientific and popular science achievements, the participating teams used unity platform and C# language to develop a mobile phone App that realizes virtual reality and three-dimensional visualization of data on the moon and Mars based on remote sensing and morphological science data obtained by lunar and Mars missions. The APP mainly realizes the three-dimensional space browsing of the digital moon and Mars, the drawing of geological objects and place names, the superposition and visualization of multi-source (composition, morphology, gravity, etc.) information, the division of geological units and the dynamic review of exploration missions, and uses augmented reality technology to complete the three-dimensional display of the landing areas of Chang 'e -4 and Tianwen -1. The App has a friendly and convenient interface to enhance the user's real interaction, and realizes the visualization of massive data, which has important scientific and popular science significance. It can not only meet the data browsing needs of professionals, but also is a popular science education tool for deep space exploration tasks and achievements in China.
