IMHO it's too early to say how often big mosaics will be taken. Mastcam can take color in a third the images of MER and it takes at least 10x less time to take a mosaic because the cameras are faster. And MSL should be able to return many times the data volume of MER. Balanced against that is the desire to target 100mm images of specific targets. We'll see how useful the narrowband filters are; if they prove valuable then that's another data consumer. And how often do you really want a full mosaic anyway, the scenery doesn't change that fast. Though it would be nice to get a pretty 360 including the deck.
Anyway, they don't let me push the button so my opinion isn't worth much. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

Given the time that SAM and CheMin (I think) take to get their samples and do their analyses, I would think there would seem to be a fair amount of time available for taking pictures and sending data. N'est-ce pas?

Maybe. But they're still in the commissioning period, and this is potentially a long-lived spacecraft. In order to help realize that potential there must be time to learn the vehicle's actual vs. projected behavior & performance...there will always be differences.
Let's not joggle their elbows. They know what they're doing. -------------------- 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.

QUOTE (centsworth_II @ Sep 4 2012, 02:41 PM) Many MER large mosaics are done during long periods of forced immobility. MSL, I expect, will have fewer such periods. I see 31 panoramas here http://pancam.astro.cornell.edu/pancam_ins.../panoramas.html If you describe 'forced immobility' as being stuck in a dune or huddling down for winter - I see only 6 that qualify. 1/5th. Long periods of IDD work, long weekends for holidays etc - are things MSL will have also. Doing a full up arm contact science, sampling, SAM and CheMin workout could take a week or two. Given that it took less than an hour to take that M34 panorama - I expect we'll see just as high a sols-between-pans ratio as MER. This team know what they're doing, and they know those big pans are a big win for outreach. |

Some of those rocks are sharp... owie owie ouch! If real, hope it's from landing & not daily wear and tear.
A few detail anaglyphs from sol 29:

I've been searching all morning for a documentary I saw recently about curiosity that starts with some artful shots of her twin in the shed at the JPL Mars yard. The close-up footage showed her wheels with large "tears" in them. When I saw that dent, that was the first thing I thought of. Anyone know what documentary I'm talking about? I think we are going to see a some very beat-up wheels in two years. |

I'm actually not warping them yet; for the moment they're just projected as a straightforward rectangle (or actually a grid). If you look really carefully, they're distorted and don't match up as well as they might. Correcting for the actual camera model will be one of the next things to try
 (Even the literature mentions the mathematics of that is complicated. It's certainly complicated for me.)

Sol 29 Navcam pan. I love to see these tracks, going to the horizon.
 Hmm… Are we there yet ? Are we there yet ? Are we […] -------------------- |

That drive was apparently the last act of Intermission; CAP 2 started sol 30. I've opened a new thread.
