Fig. 1: Dimorphos boulders’ fractures.
From: Fast boulder fracturing by thermal fatigue detected on stony asteroids
a Dimorphos high-resolution mosaic created with the final 10 DRACO images from 11.447 s to 0.856 s before the impact (pixel scale ranging between 34.9 cm/px and 2.6 cm/px), where the pink box shows the area covered by the image (dart_0401930049_43695_01_iof) analyzed in this work; b Close up of the image (dart_0401930049_43695_01_iof) acquired 1.818 s before the impact with a pixel scale of 5.5 cm where boulders’ fractures are visible and identifiable; c same as b with 54 mapped fractured on different boulders dimension where the modeled boulders are outlined by ellipses. The largest boulder in the scene (6.62 m across), Atabaque Saxum, displays 6 fractures on its surface (Supplementary Fig. 1).
