Looking around at our surroundings a bit as we look forward to the second lunar day... here is a comparison of a descent image and the reprojected circular panorama:
The main craters are probably visible on the horizon. There have been statements about driving 7 to 10 m at a time, imaging the surroundings and choosing the next drive segment. This is intermediate between the joystick-style direct driving of the Lunokhods with live (if intermittent) TV images, and the Mars experience of planning a drive of 100 m or so, imaging, and sending data down for the planners to work on the next sol. Presumably the ground team in China could do several of those short drive segments in an Earth working day, but I'm not sure they could ever get up to distances of 1000 m/day like that (the Lunokhod record was 3000 m in one Earth day). The stated goal of driving as much as 10 km would require a long extended mission, it seems to me. Phil -------------------- ... because the Solar System ain't gonna map itself.
