Since Spirit is no longer "Running for the Hills" and it appears that she will be staying at Low Ridge Haven for the next eight months or so, it seems like a good time to start a new topic.
I thought we could start with the great panorama stitched by jvandriel, and then altered by Tesheiner. We are going to become very familiar with this view in the coming months. David [attachment=5107:attachment] (286k) |

I think Spirit is still at the same place.
Here we have two navcam images: - Sol 807 (old site AR00): http://marsrovers.jpl.nasa.gov/gallery/all...00P1986L0M1.JPG - Sol 855 (new site AS00): http://marsrovers.jpl.nasa.gov/gallery/all...00P1986L0M1.JPG Do you see any movement? I don't. |

Do you see any movement? I don't. Really? Load them both up and flick back and forth....there's motion ![]() This is one image as a 'difference' of the other - the horizon has moved more than a little. PERHAPS...here's a thought..it was a scheme to exercise the wheels, without actually moving anywhere, to minimise the risk of bad sticking when they come to use them properly in a few months time? I remember there being mention of motors having high currents when driving Oppy for the first time after the Olympia hiatus, probably due to the wheels getting a big 'draggy' after being parked for so long. If they had powered each wheel in turn, just to give them a bit of exercise..they might not have moved, but they might have settled the rover a little? Doug |

Doug There is a slight overall vertical shift (4 pixels) between those two frames. But I can see no relative shift, ie parallax shift, between foreground and background objects (eg rover body and ground) on these images or on any of the series. Had there been any movement or rotation of the rover, we'd see such a parallax change. Instead the overall shifts in these frames must be just due to slight navcam pointing differences between the sol 807 and 855 frames. In fact, when I first saw these frames I was impressed that they duplicated the pointing angles as acurately as they did! |
