Starship Asterisk*

Where did this rock come from? The local Martian landscape does not appear to be very rocky. And there are no cliffs from which it fell. Being balsitic it probably came from the Martian crust, but how did this isolated rock arrive at this location ?

I believe I know the answer. Nobody knows where the rock came from. It is the kind of rock that on Earth is called an "erratic".
