Memories of El Dorado at Gusev... Will Curiosity be actually able to measure their movement on the ground, some sort of time-lapse measurements at the edges, maybe?

Almost certainly the rover would not be in one place long enough to see any movement of the dune. But it might be feasible to take high resolution MAHLI images showing individual grains several times over a few sols and get an estimate of the number of moving grains per square meter per sol, and relate it to wind speed.

The movement is on the order of 1 m/yr, or 1 cm per few days, so conceivably we might see some changes at the edges. Of course that will depend on how well-defined (ie how sharp) those edges are. More importantly, it'll depend on how uniform that movement is over the Martian year. Most of the movement might happen in a relatively short interval, such as during the summer dust storm season, in which case we might be out of luck.

Well Curiosity's ability to determine wind direction may be constrained, but in this area at least they will be able to correlate wind direction and velocity.

I note that it was mentioned that the study of the upcoming Bagnold dune field is the first attempt of its sort with regards to Mars exploration. I recall the El Dorado dune at the Spirit landing sight in Colombia Hills . Is that a completely different structure or something similar?

Just for fun.... The Bagnold Dunes: EDL to Sol 1171, Using browse MARDI images from the Analyst's Notebook and a revised JPL location map. I have annotated the approximate location of Bradbury Landing and sol 1172 onto the lower middle MARDI Frame.

Do We have a meteorite (black rock) at 10h30 approx ? Effectively, it looks like an iron meteorite (sol1158). Sadly far away now. |

Effectively, it looks like an iron meteorite (sol1158). Sadly far away now. If that rock at 10h30 is the one from sol1158 mastcam or navcam, it looks like run of the mill crater ejecta to my untrained eye at least. |

Haven't seen this here before so thought I'd share Sol 1157 [12615x2102].

We have arrived at the dunes, so time for a new thread.
