Traveling to Eve
Eve is Kerbin's closest neighbor, and therefore is the easiest to reach. Still getting to Eve, landing on it safely, and (if you're crazy) returning home is no easy task.
Specifications
- Length: 1-3 hours
- Difficulty: Moderate/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
To perform a successful landing on Eve you will need an immense rocket.
Upper Stage
Only consider building an upper stage if you want to perform a landing. It should consist of, at the very least, a lander that can touch down on the surface. You may also want to consider packing some extra fuel, in case either:
A. Your middle stage can't pull you out of Eve's orbit.
B. You want it to be capable of flying back to orbit.
Middle Stage
This is the stage you will be using to fly from Kerbin's orbit to Eve's, and possibly to decelerate into controlled descent. It's recommended this stage remain light, so thrusters with a high specific impulse, such as the LV-909 Liquid Fuel Engine or ideally, nuclear engines, are recommended for the journey.
Lower Stage
This stage should take you at least into Kerbin's orbit if you hope to reach Eve. It will require several large thrusters to lift the interplanetary vehicle itself into orbit, probably assisted by some SRBs.
Step 2 - Launch to Kerbin Orbit
First, you need to make sure the orbits of Kerbin and Eve are aligned properly, or you will not be going anywhere. Check your map and make sure that Eve is behind Kerbin in it's orbit around Kerbol, and if you were to draw a line from Eve to Kerbol to Kerbin, it would form a 60 degree angle.
Take off as usual (see Tutorials for how to achieve orbit), only tilt your craft heading east instead of the usual west. Try to aim for a circular equatorial orbit spinning clockwise at around 200,000 meters.
Important Note: Sling-shotting around Kerbin to planets with a lower Kerbolar orbit requires a retrograde orbit. The shortest and most fuel-efficient method of traveling to Eve is by traveling around Kerbin in a clockwise orbit, rather than the standard counterclockwise orbit. To do this will require a little extra fuel for the first stage, as you are flying against the spin of Kerbin.
