the GEMS Discovery finalist has been renamed InSight and now has its own website: http://insight.jpl.nasa.gov/

A Universe Today article stated that the landing site will be in Elysium Planitia: “Our planned landing site is in Elysium Planitia,” Banerdt told me. “It was chosen for optimizing engineering safety margins for landing and power.”
In emails with Banerdt, he told me that the lander will carry some meteorology instruments to characterize the effect of wind and temperature on the seismic instrument. -------------------- |

That met data is basically engineering data aka "noise". But, hopefully it can be useful scientifically as well. |

Thanks for confirming that. That met data is basically engineering data aka "noise". But, hopefully it can be useful scientifically as well. Even with the seismometer sitting on the ground with a wind shield, wind will couple some energy into the ground as it pushes on the lander. Additionally, ground deformations occur as pressure systems migrate across the surface. So ancillary meteorology data is vital to make sense of the seismic measurements (as well as being of interest in its own right). For a review of these issues (and if you want to know the ground motions produced by a Leopard 1 main battle tank...) see http://www.lpl.arizona.edu/~rlorenz/seismology.pdf |
