Extended Data Fig. 9: Modelling of the evolution of a length distribution of fractures.
From: Alignment of fractures on Bennu’s boulders indicative of rapid asteroid surface evolution
The evolution as a function of time is displayed at different epochs for a set of surface fractures with an initially microscopic length distribution (curve at t = 0 kyr). The vertical slope of the t = 50 kyr and t = 100 kyr curves are very similar to the one measured for Bennu’s boulder fractures and displayed in Fig. 3. The thick-solid curve shows the size distribution of the boulders hosting the modelled fractures.
