2 shots of Deimos, the smaller of Mars' 2 moons.
I did have a question. If these are "impact" craters have we ever actually seen one being created? check this
Looks to me to be an astro- gravel
Well being its 7 miles in diameter I don't think that can classify as 'gravel'
We need one of these, Earth with 2 moons, one being a chunk of astro-gravel.
