BuzzFeed have gotten their hands on how the NH team plans to name features on both Pluto and Charon: http://www.buzzfeed.com/alexkasprak/the-vader-crater
The names give some clues for how the science team is interpreting things: you find things named fossa, vallis, cavus, rupes, dorsa and linea - all on Pluto. EDIT: The maps on the mission website: Pluto Sputnik plain and surroundings Charon This post has been edited by Habukaz: Dec 20 2015, 09:11 PM -------------------- |

With the use of metadata of LORRI frames I clarify trajectory of New Horizons (error is about 0.000002 on distancies to Pluto at snapshots momens). After that it made possible to simulate all frames with subpixel accuracy. As a bonus Pluto radius was determined: R=240.89 km * u, where 'u' is LORRI pixel size in microradians.
If we assume that the under-Charon avarage point has longitude 0°, then the map of Pluto (for example http://www.unmannedspaceflight.com/index.p...t&id=37374) is offset by 1.6 ° to the east. So I had to make such correction to map, that the image consistent with LORRI frames. Nevertheless, clear to see that there are still quite a strong distortion in the map. Another file, which I posted earlier in http://www.unmannedspaceflight.com/index.p...8071&st=30: There is a general shift of the East, which I removed, but there are still some parts of the motion relative to each other. To generate frames I used this map: Map was taken from http://www.unmannedspaceflight.com/index.p...st&id=37232 and enlarged to the right (eastern) side and manually filled in the southern region based on the map obtained by the Hubble Space Telescope observations. |
