Mechjeb launch help


Recommended Posts

Here is my issue. I use smart A.S.S to help with my launches because it can keep everything how I want it a lot easier and I have used it with this rocket/space-plane for several equal-lateral orbits just fine but when I try to use it to launch into a polar orbit I start adjusting the pitch in the mechjeb window but instead it pitiching front to back like I would expect it starts pitching left to right which would put it into an equal-lateral orbit if the launch didn't fail for obvious reasons. I can't seem to figure out why it is doing what it is doing.

Check your heading. Your HDG is set to 90. 90 degrees is east.
Check your rol. It is set to 90 so it will stay on its side.

Change both HDG and ROL to 0 and you'll be flying true north.

I've had a few funnies with exactly polar orbits. Safer to go with, say, 85° if it is not critical.  

You're confusing him.
Yes, an inclination of 85° is often more useful than 90. But to get to a 85° inclination you have to launch at a 5° heading.

True but he mentioned using Mechjeb. If he's using it's Ascent Guidance then you'd enter "85" into "Orbit inclination" and that would steer you 5° off North.

Yes. But if you had read the OP and had looked at the images you would have known he does not use the ascent guidance. Instead he uses the SURF option in Smart A.S.S.

Oh I can't be bothered doing a proper job like that. Far easier to ramble randomly :confused:

Thanks for the help, I don't know why I did not think of that I feel kind dumb for not realizing it to begin with but thank you and it worked out just how I wanted.
