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

That's cool - PLUTO was an awesome and cunning little piece of kit.

Does seem like a shame that only one copy of this spacecraft will fit into the Discovery cost envelope. A seismometer network would provide some very interesting data.

I agree, three landings would give them the chance to use earthquakes & impacts to probe the interior of Mars in the same way Apollo allowed us to determine what was underneath the surface of the Moon.

As to the suggestion that they fit something like the weather mast used on Phoenix, they'd also need a camera to monitor it.

New techniques don't require 3 landers, they can do the science with one, thats why they have been given the go ahead for the mission.
