I'm back with some more Kerbal Space Program! This episode we are going to Minmus!

First we look at what contracts we have. We have four contracts involving Minmus: Explore Minmus, position a satellite around Minmus, perform visual surveys of Minmus, and build a orbital station around Minmus. Because of all these contracts, not is the time to go there, assuming we can accomplish all of them in one trip.

If we are to get them all done, we will need a rocked with a lander, a satellite, and a station! That's going to be heavier than what we just went to the Mun with, but landing on Minmus is actually easier than landing on the Mun, and we'll be leaving the weight of the satellite and station around Minmus, so with the amount of fuel we had left over from the Mun, this should be possible.

So we head off to the VAB to build this ship. We make a sub-assembly out of the launcher stage from our Mun rocket, but we well be remaking the lander so that it includes a larger capsule, a satellite and a space station.

We start of the lander with the large 3 man capsule. This is so we have 3 kerbals, as I'm planning the station to have a science lab, and we'll need to have two Kerbals to run that. The rest of the lander is build similar to the Mun lander, except that it is build with 3-way symmetry instead of 4-way. This saves a bit of weight but also reduces our thrust. Since Minmus has lower gravity, the lower thrust wont be an issue for landing, it will only cause out burns in orbit to take a bit longer, while it should allow our fuel to last a bit longer.

On the node of the capsule we add a docking port, so that we can dock with the station. On top of the docking port we build a small satellite, consisting of a probe body, a small fuel tank, an ant engine, a thermometer, an antenna and some solar panels. Below the lander, connected by a 3 meter decoupler, we build the station. This consists of a hitchhiker storage container and a science lab, with a small 3 meter fuel tank with a pair of mark 55 engines. A probe body and SAS unit are placed on the bottom. On the sides are placed pairs of docking ports, RCS tanks, solar panels, lights, and batteries, and two sets of 4 RCS thrusters.

All of this is then attacked on top of the launcher sub-assembly that we saved. Struts are added to prevent the rocket from wobbling as it is launched.

With everything ready, we get Bill, Bob, and Jeb aboard. We double check the staging (making a few corrections), and we are ready for launch!

We launch the rocket, and everything goes well despite the ship being heavier than the one we took to the Mun. We get into orbit with some fuel remaining in the last launch stage.

We then plan a set of burns to get to Minmus. The first burn raises our apoapsis out to Minmus' orbit, while the second corrects for Minmus' inclination. We perform these burns, but find when we are done that the periapsis at Minmus is much higher than planned. Se we do one additional small burn to lower the planned periapsis at Minmus.

With our burns to get to Minmus complete, we bring this episode to a close. Next time we will get into orbit around Minmus, and try to get the station and satellite into orbit!
