Dawn is now officially in orbit around (1) Ceres!
Congratulations, NASA. Nice images of crescent Ceres. NASA Spacecraft Becomes First to Orbit a Dwarf Planet |

It is tricky to discern the orientation of the valleys between the large basin and spot 5, so I took scalber's cylindrical map and brought it into Celestia:
Some valleys radiate from the basin, but the ones that extend to spot 5 do not. I thought all the valleys were due to the big basin, but something else seem to be in play. |

It is tricky to discern the orientation of the valleys between the large basin and spot 5, so I took scalber's cylindrical map and brought it into Celestia: This might be his real color? Here, lower, older rocks were drawn up by the central rebound. The tan in the middle is Cambrian, and the red dot represents huge, rootless blocks of Precambrian granite. The outer ring is younger Ordovician. A cross section of the structure: [attachment=36019:Decaturville_2.png] This could be one of the good reasons for central bright spot 5. I hope soon we will know.. Greetings - this map version has some revisions in the area of the two southern basins to try and show more details. [attachment=36022:ceres_rgb_cyl_1mb.jpg] Full 4K resolution and polar views are here. Incredible.. many years, long-awaited and imagined.. and is now fully mapped .. Thanks, |
