So has a landing site been chosen yet, anyone know? and what is the specific (or general) location... and don't just say "up north", latitude and longitude would be better.

Stu, I don't have the idea about the sizes of the stones. It can be interpreted as 1 cm or 1 meter since this picture has no referential size.

It would be very pity if the spacecraft loose the balance after the touchdown. The case landing MER is safer than the ones of Phoenix / Viking way of landing. This is because the ball will most probably be stopped whenever the surface is on the flat. Hope that MSL won't take so much risks as Phoenix does since MSL will cost many times more than Phoenix.

Wow, if HiRISE can suddenly spot rocks 1cm across it's had a heck of an upgrade! tongue.gif

As HiRISE's best resolution is typically - correct me if I'm wrong, someone - "around a metre" then those rocks are each bigger than Phoenix. Again, I stand ready to be corrected here guys...

... but I'm going to have nightmares about "The Hump Of Horror" on PSP_002104_2485...!!! unsure.gif

Having said that, imagine the view if Phoenix lands smack bang in the middle of that Hump... so much for "few rocks and boulders visible..." wink.gif

Actually, being serious for a moment, why would these be so many rocks here and not elsewhere in this region? Why have they collected - or gathered - around the edge of this feature? There's another similar mound further "down" the strip, and it too has rocks arranged around its edge. What gives..?

HiRISE's best resolution is actually roughly 30cm (or very roughly one foot, for those of us who still use Imperial units). That said, though, I'd think you're still correct, each of those rocks is likely as larger as, or larger than, Phoenix itself.
