The question How could InSight's seismometers be intentionally and meaningfully “pinged”? is a hypothetical and has several good speculative answers.
But here I'd like to ask specifically about any planned experiments.
Seeing as insight is originally made to detect earthquakes, and because lunar seismic detectors have been used to detect impact events, is it planned to slam a rocket body, orbiter, or any other artificial impactor into the surface some distance away from INSIGHT and detect the propagation of the waves caused by the impact?
As a side question, are there any current or future candidate objects are big enough to be potentially of use for this?
