Je to prototyp ESA k otestování odběru vzorků z povrchu těles s velmi nízkou gravitací (měsíce, asteroidy).
Měl být testován v dubnu, nebo květnu 2016 při parabolických letech.

According to one of the scientists on the project, NASA was extremely upset by the "JPL" raised letters on the wheels, wanting them to read "NASA" instead. JPL assured NASA that this was merely a prototype and that the letters wouldn't appear on the final model.
Eventually the design was finalised and approved, and the wheels were made and fitted:
I'd imagine that the NASA folks would have felt that they'd won a little victory over JPL - all of the lettering on the wheels had been designed-out.
And I'd imagine that JPL's lot would have felt far more victorious because they'd got their initials in there anyway in the form of Morse Code which NASA, apparently, didn't notice
