Year 3, day 92.
Customer: O.M.B. Demolition Enterprises
Mission Objectives:

1. Land probe on the surface of Minmus
2. Transmit scientific data back to Kerbin

Returning to our unscrewed program, we set our focus back towards Minmus. Before we send Kerbals there, we need to know a little more about the surface of the moon.

This launch returns to our R4 lifter, but with a new, liquid hydrogen-based upper stage. This gives the rocket just enough extra performance to perform this mission.

The problems from the previous flight have been isolated and no problems are expected this mission.

Year 1, day 287.
Customer: STEADLER Engineering Corps.
Mission Objectives:

1. Place satellite into polar orbit over Minmus.
2. Perform altimetry mapping of Minmus.

Commercial interest in Minmus continues, and this mission will lay the groundwork for possible future crewed missions to Minmus.

Year 1, day 278.
Customer: Moving Parts Experts Group
Mission Objectives:

1. Place the first satellite into orbit around MInmus.

This will be another G-3 probe atop an R-4.1 rocket.

Year 1, day 256.
Project: Resnick
Mission Objectives:

1. Perform flyby of Minmus.
2. Transmit scientific data form space around Minmus.

This launch features an upgraded version of the G-2 satellite, featuring larger fuel tanks and improved electrical systems. The lower stage tanks of the G-4 were lengthened slightly, to accommodate for the heavier payload.
