4. Can I see the Mars data using the Google Earth client?
Not yet, but we’re working on it. To whet your appetite, you can check out this 3-D fly-through movie of Valles Marineris made using this data.
The old pay version of Keyhole’s Earth had a Mars layer that was very popular, judging from legacy comments, and now it’s coming back. Flying over Mars is a boyhood dream of mine. Mars + network links, Mars + 3D structures, Mars + detailed imagery from Reconnaisance… I can’t wait.
