Any more information on the insight mission and how these scales will be used? Ordered 3, because NASA.
Edit- found some info
A seismic experiment will listen for "marsquakes" and use this information to map the boundaries between the rock layers inside Earth's neighbour.
It will determine if the planet has a liquid or solid core, and provide some clues as to why its surface is not divided up into tectonic plates as on Earth.
Key components of this package will come from France and the UK.
InSight will also push a German-built thermal probe into the surface to gauge Mars' temperature profile. This will reveal how the planet is cooling.
It will also deliver another sensor that will very accurately determine the degree to which the planet wobbles on its axis.JPL will provide the two cameras on InSight and a robotic arm.
