The shadow is the main problem of spacecraft orbit design. The shadow can cause a significant loss of temperature in the spacecraft, as well as a reduction in the power supply and other effects. Based on the time and phase space system, the characteristics of shadows produced by different blocking bodies are analyzed for the shadow effect of a specific vertical Lyapunov orbit in the cislunar space. The influence of different initial phases on the shadow effect of spacecraft during three years is also studied. The research provides support for the future vertical Lyapunov orbit mission.

“…The duration of a single eclipse by Mars is less than 1 h, but the duration of the eclipse by Phobos depends on the orbital shape in the inertial coordinate system (vertical scale of Fig. 1 top), and it varies depending on the periods that the spacecraft stays in the Phobos shadow areas (Chikazawa et al 2021). Particularly, during the low altitude operations, the long duration of eclipse (more than 10,000 s) occurs when the inner cycloidal shaped circle overlaps with the shadowed areas (Fig.…”

The science operations of the spacecraft and remote sensing instruments for the Martian Moon eXploration (MMX) mission are discussed by the mission operation working team. In this paper, we describe the Phobos observations during the first 1.5 years of the spacecraft’s stay around Mars, and the Deimos observations before leaving the Martian system. In the Phobos observation, the spacecraft will be placed in low-altitude quasi-satellite orbits on the equatorial plane of Phobos and will make high-resolution topographic and spectroscopic observations of the Phobos surface from five different altitudes orbits. The spacecraft will also attempt to observe polar regions of Phobos from a three-dimensional quasi-satellite orbit moving out of the equatorial plane of Phobos. From these observations, we will constrain the origin of Phobos and Deimos and select places for landing site candidates for sample collection. For the Deimos observations, the spacecraft will be injected into two resonant orbits and will perform many flybys to observe the surface of Deimos over as large an area as possible.
