How to get into low laythe orbit?

[Prat4545]

Hello everyone,

So I get a bit of gravity slingshots and gravity breaking. So I'm going to joule! (unmanned, otherwise all those poor souls). And I would like to land on laythe! So my orbit is about 68,500,000 m (apoapses and periapses (its around as big as tylo's orbit)) But how do I get into a low orbit around laythe now? I tried aerobraking because I only have 900 m / s of fuel but that is far too bad. Do you know how I can lower my speed to NOT explode in the atmosphere? Thank you in advance!

Sincerely Prat4545! (Sorry for my bad english this is checked by google translate)

900 dv is not enough to go into a low Laythe orbit at this point. If aerobraking is your only shot, try spinning the craft wildly upon entering the atmosphere. Do not use SAS. the Joolian system is very friend in terms of offering gravity slings, so try to a lot of them. They can really lower the burn you need to go into an LLO (low laythe orbit)

Okay i'll try it but do you have any advise for the next mission that i dont run out of fuel again?

i'm going at 7000 m/s Soooooo how do i lower that speed?

Remember that you don't need to aerobrake directly into a low Laythe orbit. For starters, you only need to aerobrake into a capture. That means, any trajectory that ensures you stay near your destination, instead of careening off into solar orbit again.

Ideally, you'd capture into Laythe's sphere of influence. But if you're going so fast that a single aerobraking pass doesn't do the trick without melting your spacecraft, then at least capture into Jool's sphere of influence. As long as you stay at Jool after going past Laythe, you can later encounter Laythe again, and aerobrake again.

If a safe aerobraking pass at Laythe still results in your spacecraft shooting back out into solar orbit... well, I'm afraid in that case, you did it wrong. Going this fast when arriving at Jool is a sign of not using a proper Hohmann transfer in the proper transfer window. Which is totally fair, sometimes you want to do a high energy transfer instead, to lower the travel time. But as the name implies, you'll be on a highly energetic trajectory, and you'll have to deal with that excess energy once you arrive at your destination. That typically means provisioning large amounts of spare fuel for propulsive capture. And you didn't bring enough. In such a case, two options: either abandon the mission and send another one, or cheat infinite fuel (alt+F12).

i'm trying again with some more fuel and i hope its gonna be better

Do you have heat shields? If so, Jool is so big and close that there are often opportunities to aerobrake there and reduce your speed somewhat before getting to Laythe itself. But you will need heat protection to survive it. 

Oh, and even non-aerobrake passes of the moons can help, as they can slow you if you approach them from opposite the direction they are moving.

I have one but it doesnt cover the whole craft

I did the mission again and my tip is that your periapses has to go over laythe orbit or lower! I lowered my apoapses about to the orbit of tylo and did the burn to laythe at periapses (laythe peraipses was at 60 000 m) And that burn costed 400 m/s and into a low orbit 900 m/s so i had 1800 m/s left!

This was a better try thanks for the help everyone!z
