What is a safe altitude for a low orbit around Kerbol/the sun?

 

[roopot]

I would say that the safest orbit is around the same level as Moho's. Anything under that is exponetially more difficult

Ironically you can go up to 12 000 km before a sputnick burns up, might have been 120'000 though.

Speed during that sun flight was 85km/s btw lol

You can reduce the delta v cost by doing multiple burns and taking advantage of the Oberth effect.

 

[DraconDarknight]

Do you mean having a low Pe and and using that as a catapult?
That would only work once you are in orbit.

The Oberth effect is using a celestial body's gravitational pull to slingshot yourself around, isn't it?

Like, instead of flying in front of the moon, you fly behind it, so its gravity will pull you along and give you a speed boost with less fuel, right?

Thats what I said then

 

[Baron]

Nope. That's a gravitational slingshot. The Oberth effect is the effect of having to spend far less fuel to accomplish orbital change, which happens at peak velocity, i.e. at periapsis. You can slow down dramatically or increase apoapsis far higher than you could at any other point of your orbit.

 

[DraconDarknight]

Oh just that thing they tell you to do in the tutorial lol.

 

[Baron]

It really works. Difference of 500 delta v on a Mun return to Kerbin.

 

[DraconDarknight]

Hmmm how can I get past the mun btw?
I always only manage to get to the sun no matter how well I aim a direct burn to other planets oO

 

[roopot]

you dont aim directly for them. you aim for thier orbit

 

[DraconDarknight]

That happens automatically if you set them as target.
For some reason though i always end up hitting the suns orbit if I try anything but the mun oO

 

[Baron]

You can only shoot for the planets at certain times of the year, when the transfer window becomes available.

 

[DraconDarknight]

Yeah I found out that maneuver mode is quiete useful, even though i never land in the approach angles it wants me too (or at least not where it wants me to lol). Too bad I forgot to extend the solar panels, if I hadn't I could have landed that probe on Minimus :/

 

[Angryboy]

I never really was able to use the maneuver mode properly. I'm starting to get the hang of it, after doing a proper mission

 

[DraconDarknight]

I can't do it properly either.
Still it helped me getting my lander probe to minimus and it alreadey starts transmitting data back - I was in such a good flight position thanks to it I would have even encountered the mun too if I'd just contued my journey instead of getting to Minimus
Well, if you excuse me I need to use all the data MP-1 is transmitting to get ION stuff

Those Atomic engines are more useful than I previously thought lol

 

[roopot]

WHOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!

 

[Baron]

That sure is some nice darkness.

That sure is some nice darkness.

yeah I have not unlocked lights yet. Also notice the fuel
