well, I really haven't checked in on the NASA Mars missions sites in a while (something like three years.) Part of the problem is that the massive amounts of data the rovers are collecting (yes! they're still active!) take a while to sort through, and even then, the globally significant implications (Yes! there was water on Mars! Yes! There was rainfall! Yes! There's still localized magnetic fields on Mars!) are few and far between. And slow in coming.
Of course, my main, perhaps my only, interest in Mars is for my nobble (seven years and counting I've been working on that thing.) So I'm looking for very specific information, and I get bored and wander away fast if I don't get it.
So I've been missing this sort of coolness (see above.)
Anyhoo, I just talked about this with someone a few days ago. Perspectives on what Mars looks like have improved enormously with the rover missions and the reconnaisance orbiter missions. Before then, all you had was basically a satellite view, and a dog's eye view from the previous rover. The dog's eye view of a dog with a very short leash.
Neither of these perspectives is a human one. Our elevation from the ground, or our shape or wiring, is such that we don't look down, or feel a closeness to the dirt and rocks under our feet. We're always stretching up and up to get a higher view. And the first thing we do in terra incognita is to go find a hill or promontory and get on top of it, so we can see around better. The human perspective is one of constantly changing perspective, five feet off the ground, but off an extremely variable and quick-changing ground. The human perspective is the one that fills the gap between the dog's eye view and the satellite view.
The current rovers are much taller (man's eye view) and can go much farther, and have lasted much longer. So there have been many opportunities to change that perspective. And the reconnaisance orbiter has come far lower into the Martian atmosphere than intended, and of course far lower than any previous orbiters have done. So much so that the orbiter's images have been almost at fighter-jet-eye-view. That's close to the range of human perspective.
But. There's still a gap between the rover's perspective and the orbiter's perspective. They're filling that gap with clever science and CGI. But the CGI isn't Pixar enough (even Pixar isn't Pixar enough) to read as "realistically" as a photograph. Nor should it. So the human perspective on Mars is still missing.
The end of the video above demonstrates exactly what I mean. (Starting at about 3:30.)
