Arthur T Knackerbracket has processed the following story:

Europe and Japan’s BepiColombo beamed back close-up images of the solar system’s innermost planet, flying through Mercury’s shadow to peer directly onto craters that are permanently hidden in the shadows.

BepiColombo, consisting of two conjoined spacecraft, flew past Mercury for the sixth and final time on Wednesday, using the planet’s gravitational pull to adjust its trajectory for an eventual orbital insertion in 2026. The mission launched in October 2018 as a joint venture between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA), each providing an orbiter to explore Mercury. During its latest flyby, the twin spacecraft flew above the surface of Mercury at a distance of around 180 miles (295 kilometers), according to ESA.

From this close distance, BepiColombo captured images of Mercury’s cratered surface, starting with the planet’s cold, permanently dark night side near the north pole before moving toward its sunlit northern regions.

Using its monitoring cameras (M-CAM 1), BepiColombo got its first close-up view of the boundary that separates the day and night side of Mercury. In the image above, the rims of Prokofiev, Kandinsky, Tolkien, and Gordimer craters can be seen littered across the surface of Mercury, casting permanent shadows that may contain pockets of frozen water.

Indeed, a key goal of the mission is to investigate whether Mercury holds water in its shadows, despite its close proximity to the Sun.

The massive Caloris Basin, Mercury’s largest impact crater, stretches more than 930 miles (1,500 kilometers) across and is visible at the bottom left of the image.

Although Mercury is a largely dark planet, its younger features (or more recent scarring) appear brighter on the surface. Scientists aren’t quite sure what Mercury is made of, but material that had been dug up from beneath the surface of the planet gradually grows darker with time.

ESA released a movie of the flyby you can download.

      I do not understand your hieroglyphics.

        I'm sorry, I was using emoji to say I was 'drooling' over the video. I didn't really have anything to say but wanted to indicate that I appreciated the story. My bad for not being clear.

          I thought you were sad.

            One downside of emojis is that they're up to interpretation both on the client end and even on the website itself. Apple, for example, nerfed their emojis to show water pistols instead of guns. On Facebook they have their own set of emoji and the 'rolling eyes' one (🙄), instead of looking slightly amused, looks more like it was whacked on the head and is recovering from the blow. Facebook's overrides Apple's. (that's a weird sentence.) I wouldn't be the least bit surprised if the drool isn't visible on your end. Heck, recently SN had an issue where the flags in my sig drew completely black! Janrinok might be able to go into detail about that, I would have assumed that to be a browser thing but I think he fixed it somehow on the server side.

            Point taken, though, I'll ease up on the emojis.

        I do not understand your hieroglyphics.

        This is EXACTLY why I cannot overstate the importance of choosing good emojis in programming language identifiers in order to make your code clear and comprehensible.
