You know.... With a few extra Klicks of tether and a pair of entangled lasers, I think we can set up a seriously high resolution gravity wave dector to use as a form of "telescope". The inflight "spin" would be used to unreel the tether pods, calibrate the lasers, and any "vibration" or quantum flux should give us a read. Anything out there with a gravity well should be dectable in near realtime.
We could use a "stationary" unit at the center of rotation, and three tethered units deployed between the pods, and we should be able to derive three-dimensional structure in the gravitational wave spectrum.
We could feed the information into the astrogation database, and display it in correlation with optical channels.
I think it would be advisable to have the kind of multi-spectral lasers that normally operate at relatively low wattage, but can be ramped up to appreciable power to overcome dust clouds or for other significant reasons.
They could then also be used for asteroid spectrographic analysis, among other things. Unless you'd prefer to sling a washing-machine at a comet?
