Find the first published maps of many worlds

Hello, I’m currently doing a term project that is worth a fair amount of my elective course. I have done very bad in the previous project and this one is my only chance. Therefore, please make sure you get this one correctly.
I basically only need first images of many planets/worlds, however, the image must have grids and must be legit and actually the first maps of that object.

I talked to my prof and he basically said i need 24 images, 8 images on each page in columns manner, where there will be 4 rows and 2 columns of images with only the source or link at the bottom of each page.
