So far images of Victoria - from orbit and from the ground, as Oppy approaches - have been tantalising at best, and frustrating at worst. What does everyone think we've seen so far, and what features do you think we'll see as Oppy approaches and later, when she finally arrives?

I checked the data on images R1400021 and R2200640 at the USGS catalog of MOC images and found there isn't data on image orientation, and hence on the convergence of the images.
There is, however, the altitude of the spacecraft and the slant range to the image center. A little trigonometry and we find R1400021 deviates from the vertical by 24.0° and R22000640 by 15.8°. Depending on the geometry, the images converge by anywhere from 39.8° to 8.2°. Although a larger convergence would be great, either should give enough elevation information to fill in some of the gaps in the MOLA data. Does anyone of the experts here know a source for image orientation parameters to get a better convergence figure? |

Here's a shrunken version of the image above.
If there's a way in, I'd say the on-ramp is at 9:10 (on a clock face). I see zero in the way of impact features - this is all about mass wasting. Bob Shaw -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!
