Creep stability of the proposed AIDA mission target 65803 Didymos: I. Discrete cohesionless granular physics model

•We simulate the slow spin-up of Didymos using rubble-pile models with different material and internal configurations.•The failure mode of a rubble pile depends mainly on the arrangement and size distribution of its constituent particles.•The Didymos primary in certain configurations can remain geo-...
