QUOTE (Marcin600 @ Sep 26 2022, 03:44 PM)  The illuminated rim of a relatively large crater (or some other depression). For example like here: Yes! That illustration is very clarifying. |

This is the best stack of images I could wrangle from the video at https://www.nasa.gov/feature/dart-s-final-i...prior-to-impact

Since there are no other craters, I don't think the isolated bright object is a crater rim. More likely, I think, is a large rock sticking up into the sunlight. There was a very prominent rock on Itokawa like that. Explorer1 already suggested the same thing.
I hope we will be getting better versions of the primary asteroid images as well. It looks a bit like Itokawa with rough and smooth areas. Phil -------------------- ... because the Solar System ain't gonna map itself.

QUOTE (CryptoEngineer @ Sep 26 2022, 06:40 PM) Strong vibes of 7 year old me watching Ranger 7 send photos as it crashed into the Moon in 1964. Same here. Back then, hitting the moon with a working spacecraft was hard. We have come so far since then! |

I think Ranger 9 was the only one people actually got to watch.

PNGs of a few images and downloadable 1080p video from pre-impact available from JHUAPL DART site
https://dart.jhuapl.edu/News-and-Resources/...php?id=20220926 Don't know why there is horizontal flip between video and still images. |

That impact debris/plume sequence is extraordinary. Is that about what we expected to see? I wonder is Dimorphos is still in one piece

Phil After looking at the enlarged fragment on the djellison's mosaic, now I also think it is an illuminated very large boulder on the surface - as Explorer1 suggested (you can see the texture of the rock) |

So it looks like the view from the impact video and all the frames pasted here are mirror-inverted |

I notice that the final partial frame appears somewhat out of focus. This makes sense because the frame width is apparently 16 meters and the telescope aperture is 0.21 meters, so the frame is only about 80 apertures wide. For a camera focused at infinity, the size of the focus spot should be equivalent to the aperture.

Wow, those streamers, it looks quite catastrophic! Much more violent than the SCI on Ryugu, as expected!
