# How do I transfer to JOOL?

## How do I transfer to JOOL?

Play with the prograde and retrograde vectors a bit until you see the arrows. If you get the two white arrows close enough to each other, you will get an encounter with Jool. If you cannot get an encounter, try moving your maneuver node around a little bit. Once you complete the burn, you will be on a course to Jool!

## How does the Oberth effect work?

The gain in efficiency is explained by the Oberth effect, wherein the use of a reaction engine at higher speeds generates a greater change in mechanical energy than its use at lower speeds.

How do you calculate angles in woodworking?

The formula involves dividing 360 by the number of sides to calculate the corner angle. Then divide it by two to get the miter angle. If you’re making a five-sided project with all sides equal, you divide 360 by five to get 72 degrees. So each joint or corner forms a 72-degree angle.

### What is a transfer angle?

There is a geometric construction for laying off, on another part of the same drawing or on a different drawing, an angle equal in size to one that is already drawn. This procedure, called transferring an angle, is shown in figure 4-10.

### What is the radius of kerbin?

600 000 m

Kerbin
Synodic orbital period Not defined
Orbital velocity 9 285 m/s
Physical Characteristics
Equatorial radius 600 000 m

Why are burns more efficient at periapsis?

The Oberth effect is strongest at a point in orbit known as the periapsis, where the gravitational potential is lowest, and the speed is highest. This is because a given firing of a rocket engine at high speed causes a greater change in kinetic energy than when fired otherwise similarly at lower speed.

## How do you get Kerbin to cross the joolian system?

Next, wait until Kerbin is about 50 degrees behind Jool. Set up a maneuver node at about 45 degrees past sunrise. Then, pull out your prograde vector until the dotted yellow line leaves the Joolian system and crosses Kerbin’s orbit.

## How do I perform a Jool maneuver with Kerbin?

Once you are in orbit, and Kerbin and Jool are aligned properly, select Jool as your target, it makes things a lot easier. Next, make a maneuver node about 45 degrees past sunset. Then, pull out your prograde vector until the dotted yellow line leaves the Kerbin system and crosses Jool’s orbit.

How do you get to Jool in kerbol?

Another way to reach Jool is to preform a Gravity Assist around Eve. (You can find that here: Tutorial: Gravity Assist ) You have now successfully done a mission to the Jool! Your next mission is to now go to Eeloo, the farthest planet in the Kerbol system. Or, you could also go to Moho, the one closest to the sun.

### How far ahead of Kerbin should I be from Jool?

Jool should be ~90 degrees ahead of Kerbin. While not absolutely essential, the easiest and fastest way to reach Jool from Kerbin is ensuring that they are properly aligned. Otherwise, you may spend a lot of time (possibly years) and fuel drifting until they happen to match up.
