This is one of three vintage-looking travel posters released by SpaceX for some of Mars’s more exotic locales.
Phobos and Deimos are Mars’s two moons, both of which are much smaller than our own. Of them, Phobos is probably more interesting for humans. NASA is already looking into ways to create a human transport vehicle to explore Phobos, and Buzz Aldrin believes that it might make a good place to set up an initial Martian base. From there, quick missions could be run from Phobos to the Martian surface. Phobos, interestingly, looks kind of like a potato—that’s because it’s so small and so close to the Martian surface that it’s own gravity can’t force it into a spherical shape.
