Jool. If you don't see this at some point during the tutorial, you've probably done it incorrectly.

Traveling to Jool

Jool is Kerbin's most distant neighbor, and one of the more time-consuming locations to reach. Getting to Jool is really the next step after Eve and Duna, and is an attractive target due to its large atmosphere and complex moon system.

Specifications

• Length: 1–3 hours
• Difficulty: Hard
• For version: .17

Additionally, you will need a good understanding of orbital mechanics (see Tutorials section), angles, and a lot of patience.

Steps

Step 1 - Build Your Rocket

The rocket should be a large ship with different things to land on all 5 moons docked to it in kerbin orbit

Upper Stage

Huge rocket with at least 2 rockomax jumbo fuel tanks and then capacity for all the crew that will dock to your ship

Middle Stage

To circularize orbit and start kerbin escape

Lower Stage

Massive launcher. Should be capable of carrying the rocket to orbit

Step 2 - Planetary Alignment

The alignment for a very efficient transfer is jool is slightly ahead of kerbin. You should escape kerbin with the orbit direction of jool as it will save you much fuel and troubles later when you arrive

Step 3 - Launch to Kerbin Orbit

You should first launch your main ship into orbit and then dock different landing modules to it in orbit

Step 4 - Fly from Kerbin to Jool

Make a maneuver node that is prograde and when you get a jool encounter burn to complete the maneuver

Step 5 - Arriving at Jool

When you arrive at jool you have 3 options: 1) aerobrake If possible I recommend using laythe and not jool due to jool'a thick atmosphere which is more prone to overheating your ship than laythe. Put your periapsis at 15km and also I suggest using several Klaw-heat shield modules which have probe cores and RCS to dock to your engines temporarily to protect them from exploding. 2)tylo Gravity assist Read the gravity assist page for detailed instructions on a RETROGRADE a gravity assist. 3) burn fuel The crude and fuel wasting method but is easier to perform. Just burn retrograde when you are at your jool periapsis.

After circulation

You should put your orbit in a moon unaffected region

Step 6 - Traveling to one of its moons
