Webb10 dec. 2024 · For atmospheric studies, Phobos offers a preferential position for a long-term monitoring of the Martian atmosphere on both Mars' dayside and nightside. Additionally, it could permit monitoring auroras (e.g. via UV instrument) and meteor flux (e.g. Christou et al. 2012) on the nightside. WebbNeither Phobos nor Deimos have atmospheres. They are too small, with no volatiles to create an atmosphere, and their gravity too low to retain one. Like Phobos, Deimos has characteristics that make it similar to a C-type …
