Need a little help here

[GrazzleyAtoms]

So I keep running into this one problem. I can launch fine. but once u detach my side rockets to thrust off and get out into orbit. my orbital line the blue line goes away. even if I add in a maneuver line it too will do the same. I have looked everywhere for an answer for this but nothing seems to work. starting to get mad if someone can help please let me know. I will post a screen shot as well.

You are escaping Kerbin's gravity. To get into a proper orbit try this technique:

1. Fly straight up until about 10Km

2. At 10Km turn your ship to a 45 degree angle (look on the naviball)

3. Exit to map view and wait till your AP is 100Km

4. Once the AP reaches 100Km cut your engines

5. Create a manuever at your AP

6. Burn the manuever

7. Congratz, you're in orbit

Do mean the blue line in map view? This should not disappear and sounds like a bug. Are you in career or sandbox? I would start a new sandbox game to see if that changes anything. If not, maybe backup your saves and do a fresh install.

That is a bad idea and you should never do it. It will cause your rocket to flip over and crash.

Instead, turn just a little bit to the east when your rocket exceeds 50 m/s, then turn SAS off. Your rocket will slowly continue to tilt sideways on its own (called a gravity turn). If your rocket ends up turning all the way down to 45 degrees by the time you're between 10 and 15 kilometers, that's a good place to be and you can keep letting it fly without SAS. If not*, you'll want to carefully try and correct it. Sometime between 30 and 40 kilometers you want to be flying almost level. Continue accelerating until your apoapsis rises above the atmosphere; you will start going pretty fast by the time that happens, but don't be afraid. You need that kind of speed to get into orbit (not just space, but actually orbit) anyway.

*Reasons for the turn happening too fast or too slow are generally related to too much or not enough thrust.

Might be worth noting that you need to upgrade your tracking station for your 'blue line' to work outside of Kerbin
