Rotationally induced surface slope-instabilities and the activation of CO2 activity on comet 103P/Hartley 2

•Identify a mechanism for excavating CO2 ices on Comet 103P/Hartley 2 that only affects the region of the nucleus associated with CO2 activity.•Mechanism predicts that a massive avalanche excavated CO2 ices, which activated the nucleus of Comet Hartley 2 shortly before its discovery in 1986.•Mechani...
