Yes, astronomers have created star charts and maps for other planets in our Solar System, including Mercury and Mars. These maps are not for locating stars but rather for identifying surface features, such as craters, mountains, valleys, and other geological formations on these planets.
For Mercury, NASA's MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) mission, which operated from 2004 to 2015, gathered detailed data and images of the planet's surface. This data was used to create topographic maps and detailed geological maps of Mercury.
Similarly, for Mars, various missions have provided extensive mapping and imaging data. The Mars Global Surveyor, Mars Reconnaissance Orbiter, and Mars Odyssey missions, among others, have collected high-resolution images and other data that have been used to create detailed maps of Mars. These maps showcase features like canyons, volcanoes, impact craters, and the Martian polar regions.
These maps and charts are invaluable for scientists studying the geology and surface features of these planets and for planning future missions to explore these worlds more extensively.
