Centsworth, thanks for digging up Fram! They DO seem remarkably similar, with perhaps the difference being age. So if Concepcion is 1K years old, how old is Fram? 10K? 100K?
And way cool to see Endurance in the background! Seems like a lifetime ago that we rolled to its edge. |

I'm having trouble with these very young ages. Meridiani Planum is lightly cratered by Martian standards but it still has enough craters that I'd be surprised if the age of the surface we see was less than 100 million years, say. If that's the case, only one crater in 100 should be less than a million years old, and only one crater in 100,000 should be less than a thousand years old. As we've passed far fewer than 100,000 craters of Concepción's size (maybe more like 100?), the odds of it being so young seem very slim.
All these numbers are WAGs but I doubt that they are wrong by a factor of 1,000... John |
