This series of images was taken by the small (38 x 28 x 20 cm) MASCOT lander as it descended to the surface of the asteroid Ryugu on Oct 23, 2018. It descended 41 meters from its mothership (the Japanese spacecraft Hayabusa2) to the surface below. It saw two basic kinds of rocks; dark, rough ones with shiny mineral bits inside, and brighter rocks with flat face and sharp edges. Some of the images just show bright reflections inside the camera, but most show the surface texture of an alien world. A tiny one just 1000 meters across, but a world nonetheless.

![No Kings protest on June 14, 2025
I went to the HUGE Jue 14 2025 No Kings protest in Charlottesville VA where easily over 1,000 people were protesting Trumps claim to kinghood. I have thoughts, including why attending these events is important as a citizen, but also an individual human: They can help with the feeling of helplessness.

![Bad Astronomy Newsletter comment answer 1!
A new feature on my BA newsletter is that paying subscribers can leave comments and questions. Ill pick one and then answer it, posting it on the following public newsletter. For the first one, subscriber Allan Jensen asks about JWST and when we can expect images from it.
[UPDATE: ARG! The L2 point is actually on the side of Earth OPPOSITE the Sun, not between them (which would be the L1 point). Thats what I get for running around too much, then plopping down to put together a quick video. Id promise to do better next time, but in all honesty I do make mistakes. Ill try to keep them to a minimum.]
[P.S. Sorry the first second or two of audio glitched, but it was just me saying, Hey folks! so please dont think I was being rude and unwelcoming. I was actually just being wrong at thinking my Mac would actually record the first second or two of the audio.]
