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 |

Just noting that it looks like it spans more than one pixel at this resolution (and also that it looks elongated from this vantage point). Looking a bit more closely at the images, it seems almost certain to me that it is resolved; but I haven't seen any relevant comments from the science team.

Yes I tend to agree thinking its resolved or nearly so on the first image of the sequence, but on the subsequent images it seem to get saturated and float into adjacent pixel areas -and so larger than it actually is -again Edit: It's not the first, but frames 8 and 9, the page loaded to slow so I missed the early part of the rotation sequence, but I did separate the images after the post to find out. |
