I believe we're going to need a better instrument than MAHLI for the next rover mission. An electron microscope perhaps??

...for what purpose?
MAHLI is the right instrument. The idea is to emulate field geologist methods, and the resolution provided is ideal for minerological characterization. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Curiosity may be on the verge of opening up a new chapter in Mars exploration that goes beyond geology. I probably am not allowed to mention the word in this forum. |

There was a higher resolution imager on Phoenix:
The optical and atomic-force microscopes complement MECA's wet chemisty experiments. With images from these microscopes, scientists will examine the fine detail structure of soil and water ice samples. Detection of hydrous and clay minerals by these microscopes may indicate past liquid water in the martian arctic. The optical microscope will have a resolution of 4 microns per pixel, allowing detection of particles ranging from about 10 micrometers up to the size of the field of view (about 1 millimeter by 2 millimeters). Red, green, blue, and ultraviolet LEDs will illuminate samples in differing color combinations to enhance the soil and water-ice structure and texture at these scales. The atomic force microscope will provide sample images down to 10 nanometers - the smallest scale ever examined on Mars. Using its sensors, the AFM creates a very small-scale "topographic" map showing the detailed structure of soil and ice grains. And any mission that felt it needed such an instrument would be able to use that or something similar. Phil -------------------- ... because the Solar System ain't gonna map itself.

Curiosity may be on the verge of opening up a new chapter in Mars exploration that goes beyond geology. I probably am not allowed to mention the word in this forum. You think? Come on. Sorry, that's just playing with words and trying to be clever. If you know you're not allowed to mention "the word" then you must know it's a waste of time even saying something like that. The position re Rule 1.3 has been made perfectly clear to everyone. If it's still not clear, please feel free to ask one of the Moderating team. But generally, a good guide is if you think you're "probably not allowed" to mention something, you're right, and already know it. -------------------- |

Wow. What a radical change!!!

As Mt. Sharp disappears into the dust as seen from Curiosity, I wonder if Curiosity and its environs will disappear as seen from orbit. IF so what (if any) impact will this have on operations, specifically navigation ?

That's very good Zelen'
Maybe they will start monitoring this same area in the next sols. Not an animation, but a side-by-side picture of it. @Eyesonmars. Seeing the rover or not from the orbit is not a matter of danger. Curiosity is power by RTG, she can even work during night-time. So, it's not a duststorm that will reduce the operations. -------------------- |

None. Dust storms on Mars never approach the level of optical density at the local level that they do in terrestrial deserts. Also, Curiosity does not utilize the orbiters for navigation, merely as comm links, and the atmospheric dust levels do not degrade even this to a significant degree.
MSL uses both optical techniques and inertial navigation for these functions. Furthermore, it's not solar-powered; dust storms are a FAR more significant hazard for Opportunity. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

If we do get a dust storm right over Gale, I think that could make MSL invisible from orbit, based on orbital dust storm images I've seen. (Didn't tau hit something like 5 during the '07 storm?)
But that doesn't matter at all, since we already have hirise imagery and we know exactly where MSL is. |

And just to remember : Viking 2 was not very exactly located, and it didn't affect ground operations. So, this is the same thing with Curiosity, even if it's a mobile lander.

There can be this series of photos consecutive shooting from the horizon to a zenith?

It feels good, Zelenyikot - and I'd love to see the equivalent when it's more-or-less dustless.
