要做到这一点，请检查您的星图，并确保Eve在绕Kerbol轨道上落后于Kerbin，而且Eve-Kerbol联线和Kerbin-Kerbol联线之间的夹角约等于60°。From this angle, you can get to a height of 200 km around Kerbin, orbit retrograde until Eve is directly behind Kerbin, and burn until you have reached a velocity of roughly 3000 m/s for a direct path to Eve.
Alternatively, you can visit The Interplanetary Guide and Calculator to calculate your own path.
Step 3 - Launch to Kerbin Orbit
Take off as usual into an eastward orbit (see Tutorials for how to achieve orbit). Unless you've done your own calculations, try to aim for a circular equatorial orbit at around 200,000 meters.
Step 4 - Fly from Kerbin to Eve
If you have successfully reached your desired orbit around Kerbin, begin your high-velocity burn. Keep an eye on your map, as mentioned above you will need to wait until Kerbin sits exactly between you and Eve, and get your velocity up to approximately 3060 m/s.
It's really important to watch the map while you are accelerating. As you accelerate your Kerbolar orbital path should move to intersect Eve's. If all goes well, there should be a brief moment where you are captured by Eve's gravity well right around the target velocity. Immediately cut your thrust. If you overshoot, just turn the craft around and do a slight retro burn until you are caught again.
Your orbit will probably be a bit higher or lower than Eve's. Just warp to the next ascending/descending node (If you don't have one, make sure you have set Eve as your target) and burn until both nodes are at 0.
This journey should take about 200+ days, so hit the warp key and enjoy the ride.
Step 5 - Arriving at Eve
When you enter Eve's sphere of influence you will almost certainly be travelling at escape velocity. If you have the fuel, simply burn retrograde at periapsis until you are in some kind of orbit.
You can greatly reduce the amount of fuel required to achieve an orbit around Eve by aerobraking. As shown on the information page, Eve's atmosphere begins around 90 km, so if you pass Eve with a periapsis slightly lower than that, the atmosphere will bleed off some speed before you retro burn in to an orbit.
You can continue to lower your orbit with aerobraking by keeping your periapsis slightly below 90 km. If you are not planning on landing, execute a prograde burn at apoapsis to raise your periapsis above the atmosphere once your apoapsis is low enough. Unless you have escape velocity or an extremely wide orbit (Or a good Heat shield and radiator panels), going below 80 km will probably result in overheating.
Step 6 - Land on Eve (Optional)
Adjust your orbital path to where you would like to land, and continue aerobraking to bleed off that extra velocity. Eventually you will be caught on a terminal descent through the atmosphere. You will notice that due to the thicker and larger atmosphere than Kerbin's you will descend much more slowly. Deploy your chute(s) to slow down even further. Lower whatever landing gear you brought with you and fire retrorockets if the chutes aren't slowing you down enough. Ultimately we're going for a typical touchdown speed (6–12 m/s).
Congratulations! You've landed on Eve!
