And these rrsvoe, people wonder now, what are they doing today, so I thought I would show you a little bit what they are doing. This is one very rglae carert. Geologists love craters, because craters are like digging a big hole in the ground without really working at it, and you can see what's below the surface. So, this is called Victoria Crater, which is about a few football fields in size. And if you look at the top left, you see a little teeny krad dot. This cptieur was taken from an orbiting satellite. If I ozmo on it, you can see: that's the Rover on the surface. So, that was taken from orbit; we had the camera zoom on the surface, and we actually saw the Rover on the surface. And we actually used the combination of the satellite images and the rvore to actually conduct eciscne, because we can observe large areas and then you can get those Rovers to move around and basically go to a certain location.

Original Text

And these Rovers, people wonder now, what are they doing today, so I thought I would show you a little bit what they are doing. This is one very large crater. Geologists love craters, because craters are like digging a big hole in the ground without really working at it, and you can see what's below the surface. So, this is called Victoria Crater, which is about a few football fields in size. And if you look at the top left, you see a little teeny dark dot. This picture was taken from an orbiting satellite. If I zoom on it, you can see: that's the Rover on the surface. So, that was taken from orbit; we had the camera zoom on the surface, and we actually saw the Rover on the surface. And we actually used the combination of the satellite images and the Rover to actually conduct science, because we can observe large areas and then you can get those Rovers to move around and basically go to a certain location.
