I would like them to extend the expiration period that applies to collectors to the prospectors. You would only ever need 1 prospector, launch it, and when you direct your ship at a roid, the prospetor goes to it. Once you have your info on the roid, you mine it (or not) and then when you move to the next roid, the prospector leaves the first roid and then heads to the next roid you approach. You only need to launch a new prospetor after the one you are using expires. This makes them like a short lifespan scanning tool, reuable for a period of time determined by the A-E rating of your controller purchase.. I think the logical extension/progression is the mining scanner you mention.....
