Phobos in martian sky http://www.youtube.com/watch?v=9QaQ6TCWq-0 That's awesome. I was wondering what that was! On my take of it, I enhanced the contrast and a haze can be seen. Is that indeed the atmosphere? -------------------- |

That's a cosmic ray hit.

That's awesome. I was wondering what that was! On my take of it, I enhanced the contrast and a haze can be seen. Is that indeed the atmosphere? I subtracted the median of all frames and enhanced the contrast. I don't know enough to interpret it for sure, but it sure looks like very well defined clouds drifting by. http://www.youtube.com/watch?v=AFa27WtnFHI (if you watch in HD it has the full resolution of the original 511x511 images, although there are some compression artifacts). |

Thank you very much, Zelenyikot!
The enhanced two-image gif (based on NASA/JPL-Caltech/MSSS) makes things more obvious. |

Wow! A few full resolution images of Deimos and Phobos have come in. Here's my take at taking out the noise and leaving the moons.
Edited to add two more: a Mastcam 34 shot and a MastCam 100 shot of Phobos. -------------------- |

I think I'm seeing the large Stickney crater, and possibly Reldresal crater too. What Phobos features can you see here?

That most certainly, to me, looks like the Stickney crater. Man, that's awesome. Good looking out.

Here's a Stellarium screenshot, set for the place, time, and the approximate field of view of the Mastcam shot. Some of the brighter stars are indicated, I wonder if image-processing wizards here can bring them out in the Mastcam shots.
http://www.pictureshack.us/images/87310_phobosdeimos2.jpg Also of interest may be the saturation-enhanced closeup of Phobos. I wonder is these colours are due to how Mastcam processed the image, or are they the real subtle colour variations of the surface. -------------------- Curiosity rover panoramas: http://www.facebook.com/CuriosityRoverPanoramas

Sorry folks, I think you have your Phobos geography all tangled up. The clearly visible crater is Hall at the south pole, north is at left, Stickney is at the bottom, essentially invisible because the sun is shining straight into it. I will post a comparison image later when I can get to it. (turn that Viking image 180 degrees for an idea of what you're seeing, except the illumination is different)

I trust and believe your words, Phil. But to me it did look like it could be Stickney in the image. I'm looking forward to seeing the comparison image because I couldn't find anything on Google.
