Economical with the truth?
"and there were no instruments designed to do surface science after landing"
This is untrue. There was a surface science package (SSP) on the Huygens probe that was designed to measure surface properties. Hence the name. Whilst there was no experiment to determine the properties of a solid surface by a direct sample there were several experiments to measure liquid properties for a potential liquid landing. Also the penetrometer and accelerometer data were used to determine the surface composition.
I know this because I designed and wrote the SSP s/w!
Having said that I think it is a great idea anyway.
