Well, partially luck, and partially the landing legs that were designed to collapse is such a way as to keep the lander level despite uneven terrain.

Ah, yes, I didn't think of that. Is there info on the specific amounts of collapse of each leg? Well, from a purely empirical point of view, the legs could not have been pushed back up much at all since the tops of the legs are not projecting through the holes on the science deck that I assume are there for just that purpose? I noticed they took some images of those holes early on in the mission; presumably to check for exactly that. Airbag |

There are some interesting but mysterious images up from Sol 21; look for "Full Frame Caterpillar Dodo-Goldilocks 3 Change Monitoring", e.g.:
http://www.met.tamu.edu/mars/i/SS021ESF898...5_12BB0L5M1.jpg Now what makes them interesting is that they are marked as being taken with the solar filters, and are very narrow, and then the names of course. So, perhaps by using the solar filter, these are very long exposures of a particular part of the trench, and then (to monitor changes) either the camera would move very slowly, or, more likely, only a few scan lines would be read in from the stationary CCD. In either case, the vertical direction of the image should correspond to changes with time of the brightness (melting ice?) of a fixed spot on the ground. Well, that is my theory, anyway! However, I can't make head or tail of the images...they look like mostly noise to me. Any takers? Airbag |

Yes, there was a wee bit of a mix up sol 15. Activity IDs, which are used to connect observations to data products, were mis-assigned. Things that were supposed to be separate observations got lumped. There'll be a note on the page at some point... But you may safely assume that none of the images that look like noise were supposed to be the trench or the telltale.

Yes very good flyover, speaking as another who cannot see the anaglyphs.
of course we will never be able to land in such rough terrain. roy |

I'm confused...
Starting on sol 20 the Peter Pan sequences transitioned to 'near field' work which implies that the horizon pan was done. However I can't find any images taken (or planned) between 90 and 130 degrees. Am I missing something? James -------------------- |

Starting on sol 20 the Peter Pan sequences transitioned to 'near field' work which implies that the horizon pan was done. However I can't find any images taken (or planned) between 90 and 130 degrees. Am I missing something? There've been some interesting choices. There is a list of prioritized images with time of day constraints that depend on direction. Ideally, when a time is available, the highest priority set that fits that time goes into the plan. Ideally they do not wander around in time. There is a 3x2 chunk of horizon missing; a 3x1 (top part) was taken on 22 and was on the lander prior to shutdown. I haven't checked the analysis of what survived shutdown to make it to the AM pass. Many sol 20 pan images were lost when an MRO pass failed and there was too much unsent data for the meager flash--that's an everyday risk. |

Thanks for the quick and detailed reply Mark, an interesting insight into the sol to sol operations.
Glad I haven't missed anything, but sorry some has been lost - looking forward to more when you get it. James -------------------- |
