QUOTE (Floyd @ Nov 27 2021, 10:34 PM)  I assume you mean images from the LICIACube. Google is your friend--good to develop the skill to answer your own questions. Lots of information on this satellite including the two cameras Leia and Luke. The most detailed information I've come across in in this PDF "LICIACube is equipped with two optical cameras (narrow and wide FoV) that allow acquiring significant images and evidence of the DART mission fulfillment. The primary instrument, named LEIA (Liciacube Explorer Imaging for Asteroid), is a catadioptric camera composed of two reflective elements and three refractive elements with a FoV of ± 2.06° on the sensor diagonal. The optic is designed to work in focus between 25 km and infinity and the detector is a monochromatic CMOS sensor with 2048x2048 pixel. The latter is equipped with a Panchromatic filters centered at 650nm±250nm. The primary camera will acquire pictures from a high distance providing high level of details of the frame field. The secondary instrument, named LUKE (Liciacube Unit Key Explorer), is the Gecko imager from SCS space, a camera with an RGB Bayer pattern filter, designed to work in focus between 400 m to infinity. The sensor unit is designed to contain the image sensor interfacing with a NanoCU, while the optics consists of a ruggedized, mission configurable aperture, lens and required spectral filters. Moreover, the hardware is capable of directly integrating the image data to the integrated mass storage." I'll let you do the math to find the resolution. we could easily get a 4k or 8k texture map from those images hopefully someone creates a shape model from the imagery (as radar meshes tend to not be fully correct, good example of this is toutatis), so i am able to properly reproject the stuff |

Nice overview paper on ESA's Hera expedition.

Didymos ahead in DRACO!
Not much given they were from from late July, but new observations were taken in August as well (not released yet). Two and a half weeks left, where did the time go? |

Fascinated to see the results from this mission - 4 days to impact!

This brings me big memories of Deep Impact that summer of 2005, and watching the early webcasts (how quaint they were).
One of the press releases mentions LICIACube will take a few days to relay the plume images back, so it won't be quite the same in terms of immediate feedback, but still looking forward to it! |

Can't see the binary distinguished yet... but soon! Quite a bit of 'bouncing' for now.

On the stream they just mentioned that they're seeing Dimorphos now. So that might be real.

Looks pretty convincing:
400% zoom with gamma tweak. |
