More Kerbal Space Program 0.9 Beta Career mode coming your way in this video!

Having delivered a satellite to orbit and rescuing a Kerbal in the last episode, we have enough funds to upgrade the launch pad to the final level. This will allow up to launch rocket of any weight.

We then go to Mission Control and pick up some new contracts. We find several Mun related contracts, so we decide to head back to the Mun and get as many of them done as possible. We already had a contract to put a satellite around the mun. We pick up a contract for temperature scans of the Mun, another for returning science data from the mun, another for planting a flag, and finally a fourth for visual surveys of the Mun.

We then go to the R&D Labs and pick up Heavier Rocketry that unlocks the mainsail engine, on large orange tank and the NASA liquid boosters, and we also pick up Advanced Landing, which gives us heavier landing gear and the drogue parachutes. Both of these will simplify the rocket we will build for these contracts.

We then head to the VAB to build this rocket. We want to get to the Mun, put a satellite in orbit, and have enough fuel to pass over several locations and land and lift off again at at least two different location before return back to Kerbin. That means building a lander with a lot of fuel and a series of launch stages with enough fuel to get the lander into Mun orbit without using any of the lander's fuel (like we had to do the last time we went to the Mun).

We start building a lander with a single man command pud, and an RCS fuel tank below it. We put the medium 2.5 meter fuel tank below that with 4 of the same height 1.25 meter fuel tanks around it. Attached to those fuel tanks are materials bays and goo canisters on the top, and 2 landing legs each on the bottom as well as an RCS thruster. We use fuel lines to connect the four outer tanks to the center one, which gets a poodle engine below it. We put 4 radial parachutes on the center tank, and 4 drogue chutes on top of the materials bay. We also add a thermometer and an antenna to the command pod and a small solar panel to each outer fuel tank, as well as a pair of lights and a pair of batteries.

We then build a small satellite on top of the command pod consisting of a small probe body, a small rcs tank, a small fuel tank, an any engine, and 3 solar panels. It isn't until after we launch that I notice that I never put RCS thrusters on the satellite.

Below the lander we build a transfer stage consisting of another medium 2.5 meter tank and a poodle engine.

For launch stages, we build a large orange tank on top of a medium tank, on top of a mainsail engine. Around this, we have four copies of the same tanks, this time on top of skipper engines, with fuel lines so that the these tanks also supply the mainsail. each of these outer tanks also get a Nasa Liquid 1x2 booster as well. Separatrons are arranged to help outer stages leave the rocket without issues. Struts are added to keep everything from wobbling around. Finally launch stability enhancers are added to hold the rocket to the pad. The staging is double checked, and we are ready to go.

The rocket had 159 parts and weighs 525 tons. On the launch pad, everything looks good, so we launch. The rocket leaps off the pad and heads skyward. By 4 km, we have to throttle down as we are approaching 200 m/s. WE have to throttle down more at 6 km, and just above 9 km we throttle back up to full and stage as the liquid boosters are finally out of fuel. We then start our gravity turn on our way to orbit. At about 49 km we stage again, leaving our mainsail engine stage. We coast up to about 80 km, and then burn to circularize our orbit.

Once in orbit, we plan a burn to the Mun, we is about 20 minutes away. We aren't perfectly aligned, so we will have an initial burn, then a small correction to come in along the Mun instead of under it. We do the initial burn with the fuel remaining in our launch stage, with lasts for about 3/4 of the burn, before switching to our transfer stage. We coast for about 10 minutes until we are ready for the correction burn, which is just a small 10 second burn.

We coast out to the Mun. Once we get in it's sphere of influence, we notice that we will be ending up orbiting in the opposite direction for how the satellite is supposed to orbit. This would make getting the satellite in the correct orbit nearly impossible, so we plot another correction that will have us come around the other side on the Mun. Since we are so far away still, this only takes a burn of a bit over 200 m/s. We perform the burn, and we are now ready to get into orbit in the correction direction.

However, getting into orbit and accomplishing the other mission tasks will be in the next episode! I'll see you then!
