Some of those areas have NO features at all!! Even with a descent camera - I wonder how easy localisation will be Actually - given MRO's huge swath width and resolution, easy Doug |

As I understand it - the pre-launch ellipse ( i.e. what they'll pick ) will be 'butterfly' shape becasue the geometry will change so much between the opening and closing of the launch window.
Now - as the ellipse moves from the opening to the closing position, it draws out quite a large area they have to 'certify' as suitable for landing....not easy. More equatorial sites, the ellipse just moves around just a little. http://sci.esa.int/science-e/www/object/do...fobjectid=36770 is quite interesting on the issue - not sure how up to date that is however. (attached - screenshot of interesting page) http://www.lpi.usra.edu/meetings/lpsc2006/pdf/2341.pdf as well The phrase 'butteryfly' gets mentioned, which I believe is the shape drawn by the opening and closing ellipse http://www.msss.com/mars_images/moc/guest/...23_phoenix.html Doug |
