Kind of answers my point too, there would be no orbit vehicle with the amount of bandwith to transmit back anything like that amount of traffic.
What's the chances that the first few collisions produce some new type of energy/matter that rips right through those detectors?
The main problem with an orbital design is the atmosphere, any by products from the collision would be absorbed by the atmosphere before they got anywhere near the detector. In the LHC the atmosphere has been almost completely removed. I believe it's at a similar level to the atmosphere of the moon.
Also you need a lot of collisions occurring at a known location in order to record enough data to see what the products are released, much of the byproducts will just pass straight through the detector without interacting.
