Our tried-and-true 3-satellite communications network is coming to Minmus. Successful use of the constellation around both Kerbin and Mun have deterred engineers from implementing more complex solutions, although they certainly thought about them. The satellite will carry two dishes and one antenna. The antenna will serve for the local omni network while the dishes allow for direct comms to Mun and indirect comms to Kerbin, routed through the IP ComSats. A lofty 1,150km orbit will provide for a very stable constellation once all satellites are in place. The transfer stage contains a probe core that will allow for any remaining fuel to be used to send the stage into Minmus for impact experiments in the future.
We've properly adjusted our trajectory slightly to bring us down to 15km as originally planned and will be able to snap photos of Minmus from close up before and after the maneuver that will send the probe back up to 1,150km and into its operational orbit.
