I’ve updated the image galleries on the blog (see the drop-down menu(s) under the header graphic); the current main categories are Planets, Dwarf Planets, Moons, Asteroids, Comets, Exoplanets and Space Miscellaneous, which then link to more specific subcategories such as Mars, Enceladus, Saturn, etc. Those are then in turn organized by specific planetary robotic missions or telescopic observations, such as Cassini, Kepler, Mars Reconnaissance Orbiter, etc. These are still a work-in-progress, and I still have to add the Mars images, but more images in all categories will be added as I have time. These include public domain photographs, illustrations and diagrams from NASA and other space agencies. You may need to also scroll down the main blog page a bit in order to view some of the longer listings in the drop-down menu(s), such as Moons. The Space Miscellaneous category includes various other space-related images of interest, such as the Sun, International Space Station, etc.
I’ve also updated the links listings in the right-hand column of the blog to now include Previous Missions and Future Missions as well as the Current Missions, for quick access to information on all of the various planetary robotic missions over the years (including orbiting telescopes) and those still to come.
