"Humongous Anaglyph III" ...and is now in z-axis heaven. That's what we've been waiting for. Thanks for all your work on that.Sol 45 and Sol 23 MC100 with a 210 meter wide baseline... Yup. Elvis has now left the building... About marsshine on Phobos, I'm skeptical considering all the blocky jpeg artifacts in the sky. But the thought is really interesting. Mars would look huge from Phobos, much bigger than the Earth from the Moon. So if the geometry is right, the marsshine could be very bright. It's hard to see earthshine on the Moon unless the sky is quite dark. But it could be much easier to see marsshine on Phobos... (Emily - according to Joe's site, the Phobos image was taken at 17:27 LMST, not near local noon. That's consistent with it's orientation at sunset.) |

Sol 49 late afternoon panorama.

Just looking back at the Phobos images from sol 45... I thought it might be useful to combine the two best images to reduce JPG noise... but it looks like there is too much rotation of Phobos (and/or the terminator) for that to work.
PS my daughter informs me that I use too many ...s in my emails to her. I have decided to move them all here instead... enjoy! ... Phil -------------------- ... because the Solar System ain't gonna map itself.

Stitched out of 12 Mastcam 34 mm images - Sol 49:
Big version here. Nice texture on the stones and rocks! And a second-but-not-so-impressive one: Big version here. |

it looks like there is too much rotation of Phobos (and/or the terminator) for that to work. Yeah, I noticed that too. But rotation seems unlikely, since the two frames were taken only 16 seconds apart. Maybe the lower S/N frame is too heavily corrupted by jpeg artifacts?Anyway, we can hope for cleaner images in the press release tomorrow... |

That's right... Kepler invented them, I believe.

Phil
Applying your reasoning and examples to what we see at Mt. Sharp it would seem highly unlikely that any of the layers we see were deposited by a fluid. Any comments folks ? (I suppose since our primary goal is the underlying phyllosilicates this is not of primary interest.) On the other hand on Emily's webcast today she showed what appeared to be a channel which turned into an inverted delta(somewhere near Mt. Sharp). It would be interesting to see this on a countour map. When I saw Emily's image I immediately thought of the fluvial like channels on the interior crater walls that turned out to be not quite the proof of running water on mars that we at first thought. |

I present you with an anaglyph of a rock. From Left & Right SOL 50 NAVCAMS
Link to Right NAVCAM image http://mars.jpl.nasa.gov/msl-raw-images/pr...NCAM00435M_.JPG It is not even a great anaglyph. As it stands it seems to me to me to have the suggestion of an outer crust. However, I may be reading to much into nothing but blurry shadows. If someone with more skill is also intrigued perhaps they could improve the Navcams. EDIT Never-mind! I found a 2nd DOWNSAMPLED NAVCAM view that presents a different lighting situation. It now looks like a normal rock. |
