Yeah, this image was simultaneous with the RLB sequence. Very cool indeed! Was this never done with MER?
The darkening moving over to the mound makes sense - the shadow (penumbra) of Phobos is on the order of the size of Phobos, ie 20-odd km. (Actually the penumbra will be somewhat wider.) The mound is several km away. |

Here is the image taken ("rescan" mode) on its mission Sol 423 : the darkening of the Phobos shadow flying above its Chryse Planitia site can be seen easily also. Cheers ! |
