I put one IAS map sensor/dish on top of the rocket/prob and two (perhaps more) Kethane detectors to the side. Polar orbits for mapping then kethane detecting in same orbit and compare, writing down the center of deposits with amount of fuel in the deposits. I time increase 50x when mapping. If I remember right ISA will map under 250k height AGL and Kethane detection (I not sure?) under 200K. By using two detectors (or more) activated opposite in time I get a nice map with better resolution for the same time of mapping with one. http://imgur.com/gsc862t Currently I have a ship/prob with 2 IAS dish on top and 6 Kethane detectors spaced out from the sides of the ship with long I beams headed to Jool. http://imgur.com/e8aA8Ok I have tried this in orbit of Kerbal and like the mapping results with the detectors activation spaces out. All of this is in version 1.9. I am stating to play with version 2.0 but have yet to figure how to successfully transfer add on's and ships/miners/probes over. BJ Quest PS: The Two attached rovers to the scout ship are fuel trucks that hook up to the Kethane mining rig with a winch cable that can attach to ships to transfer fuel. Mods I use are: parts from nova punch pack(6.25mm tank and engine), Kethane, winch, as well as ISA map mods. The Scout can be used to explore the surface once the rovers/fuel truck are dumped off at the mining rig. I do use the FTmN400 Nuclear engine in the middle stage on both rockets. The Ranger (with 6 detectors) has this nuclear engine as it core power source.
