Vehicle tracks are visible on the ice, converging toward the 6-metre-wide hole. Most of the tracks run from the impact area to Chebarkul, 2.5 km east. The asteroid that entered the atmosphere was 17 m across and took 32.5 seconds to break up into several fragments. An underwater expedition is underway to recover the fragment at the bottom of the lake.
The Pléiades satellites generate 50-cm-resolution products ideally suited to precision mapping and photointerpretation. The identical twin satellites operate as a constellation in the same orbit, phased 180° apart. This unique configuration gives them a daily revisit capability to rapidly acquire imagery of an area of interest or monitor a crisis.
