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) |

So fragil that some gushing wind may break it off. I have also measured it but I got different result. According to GIMP tool, the given distance is 130.9 pixels. Then, the picture has 1024x1024 pixels (this is of 1 Megapixels) and its proportion is 2.8346 has pixels/mm (36.124 cms width and 36.124 height). Then the size of "flying stone" is 46.18 mm (130.9/2.8346). How do you get to measure it as 160 mm long? Changing the topic, around the Low Ridge Heaven has many strange and rugged stones (ones which has undergone a process of great temperature that has produced bubbles of gas) that might be of volcanic or impact origns. So Spirit with its limited permissible autonomy can visit some stones facing to the northern side. One of interesting lava rocks http://qt.exploratorium.edu/mars/spirit/pa...00P2535R1M1.JPG Rodolfo |

Rodolfo I verified the measurement, measuring to the right tip of the projection, and got 18 cm with about a 1 cm error, basically in agreement with alan's measurement (he set the right side of the measurement a bit to the left of where I did). I'm not sure how he did it, but I used my own app, AlgorimancerPG, which you can find at http://www.clarkandersen.com/RangeFinder.htm. I'm not familiar with GIMP, so I don't have any idea of why it offers different results. |
