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 1,500km 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.
The rocket has been rolled out and hooked up to umbilical towers on the launchpad. Final readiness checks and weather briefing tonight and launcg tomorrow morning at 12:00:27 UTC, which is under the ascending node of Minmus' orbit, allowing the rocket to match inclination during ascent.
