dc.descriptionThe data consist of 11 animated sequences, each with a leading panel that provides a summary of what is portrayed in that sequence. Additional information is given in the accompanying text for each file. Identical sequences are provided in both MOV and MP4 formats. Displaying with Quicktime or a similar app allows the user to play the movie at different speeds, and also to step through the sequence a frame at a time, which is helpful for following the details as the ejecta evolves. Time tags (seconds since the time of impact) are incorporated to help identify the images in the sequence. Zip files containing all 11 animated sequences are included for both MOV and MP4 versions.
dc.description.abstractThis data collection contains animated sequences showing different aspects of the ejecta that were observed after the Double Asteroid Impact Test (DART) spacecraft crashed into Dimorphos, the moon of asteroid (65803) Didymos on September 26, 2022. The images comprising the sequences were obtained with the LICIACube Unit Key Explorer (LUKE) instrument on board the LICIACube spacecraft that flew by the Didymos system about 3 minutes after the impact event. Although the sequences are comprised of the same observations they are presented in different ways to emphasize various aspects of the ejecta field. These animations are intended as a supplement to the individual LUKE images, to provide insight and to help in the interpretation of the data in support of studies that address spatial and temporal changes in the DART ejecta field. Note that in some of the sequences, black sections may encroach in from the sides. These are gaps in the data where the asteroids moved to the edge of the camera's detector.
dc.description.sponsorshipThis study was supported in part by the DART mission, National Aeronautics and Space Administration (NASA) contract No. 80MSFC20D0004 to JHU/APL.

Description:
MOV Version: Sequence showing the large (meter-sized) boulders in the DART ejecta. Images are registered on Didymos and scaled to a common spacecraft range. The boulders can be seen sweeping in front of Didymos as the spacecraft flies by. A total of 104 boulders were tracked and their 3-dimensional positions derived. Another 30-40 were detected, but could not be tracked. Select boulders are circled and numbered in the images where they were measured.

Description:
MOV Version: Sequence showing the approach phase, centered on Didymos. 1000x1000 pixel subsections of the images reflect what was observed by LICIACube. The approach phase is defined as the times from 29 to 140 sec after impact, when the changes in the observation conditions were primarily radial as the spacecraft got closer to the asteroid, but experienced little change in the viewing direction over time.

Description:
MOV Version: Sequence showing the appearance of Didymos during the flyby sequence (140 to 195 sec after impact). Subsections have been extracted and scaled to a common distance to highlight the primary body. Because of this scaling, the spatial resolution in the images changes throughout the sequence.
