China will launch the “Tianwen-IV” mission around 2030, focusing on the orbiting exploration of Jupiter and Callisto, a moon of Jupiter. As part of this ambitious mission, a main satellite will carry another satellite that will be released in the

A navigation camera or topography camera is a standard payload for deep space missions and the image data are normally used for auto-navigation. In this work, we study the potential contribution of image data in precise orbit determination for deep s

The main belt comet 133P/Elst-Pizarro is one of the targets of the proposed Chinese small body exploration mission. The rotation and gravity of this comet will be modelled at the end of the mission phase. To prepare this mission, we performed a radio

Context. Accurate gravity and ephemerides estimations for Neptune and its satellites are necessary for the forthcoming deep space exploration missions targeting its system. In addition, these estimations are also meaningful for the modeling of Neptun

The Main Belt Comet 133P/Elst-Pizarro is one of the targets in China’s asteroid exploration mission. To support this goal, gravity field estimation for this celestial object was simulated and analyzed using two-way and four-way range rate observati

Context. The cryptomare in the Balmer-Kapteyn region is the oldest one on the Moon. Determining the extent and formation of this feature can deepen our understanding of early mare volcanism and help establish temporal and spatial constraints on lunar

The FeO and TiO2 contents are critical for distinguishing petrological properties of the Moon and for studying the distribution of the lunar maria and its multi-period volcanic activity. Traditional methods used the ratio between spectral reflectance

High-precision Mars orientation and rotation parameters (MOP) can constrain the internal structure of the planet and the modeling of processes such as polar dry ice waning and waxing. Currently, these orientation parameters are obtained by using trad
