I never really "got" gravity assists...

[magnemoe]

It is absolutely possible to get low flybys of everything and sling back to Kerbin. For my "grand tour" I landed on Pol and Bop which cost quite a bit, but if you never capture, you should be able to hit everything for very low delta-v.

Bob and Pol is not so expensive, one smart tricks is to do an Laythe aerobrake who put your Ap at the edge of SOI, raise Pe out of atmosphere, now wait for Ap to be forward of Laythe orbit so raising it a bit put you in an Jool orbit between with Pe near Laythe and Ap ap out to Pol, you might use additional assists to raise Pe while waiting for an Pol intercept, Recommend doing Pol first as you don't have to undo the Bop plane change.

You might want to just take the lander to Bop and Pol and keep the mothership in orbit outside Tylo.

I can do better:

pi=3,14159265358979323846264338327950288519716939917510582097494459230781640628628089986280248253421170679814808651328230664709384460955058223172535940812864462294895493038194428810975665933446128475648233786783165271201909145648566923460348610

Yes, I'm learning the digit of pi(201(3 is included) so far) for fun...

(I have no life )

Periodic table, go!

Hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, magnesium, alimuinum, silicon, phosphorus, sulfur, chlorine, argon, potassium, calcium, scandium, titanium, vanadium, chromium, maganese, iron, cobalt, nickel, copper, zinc, gallium, germanium, arsenic, selenium, bromine, krypton, rubidium, strontium, yttrium, zirconium, niobium, molybdenum, technetium.

And that's all I got.

Anyway, to stay on topic, the only place better then Jool to get gravity assists from is the planet from the mod pack 'the sentar expansion' a tylo moon, a laythe moon, a retrograde Titan like moon, and a moon with a gravity of 3.14gees and no atmosphere (called ringle, Erin, skeletion and thud, repecitivly)

Intercept is not expensive, insertion is expensive. And even then, not all that expensive in an absolute sense, just much more expensive than the intercept, which you can get almost for free with gravity assists.

Yes, having aspergers is quite useful at times. I.e pi=3.14159265358979323238462634338327.

Duplicate one-thousand-million-billionth value. You lose.

Jool is indeed fun. Once you're there it doesn't really require that much dV to get to anywhere in the system, particularly if you're already in amongst the orbits of the moons

I do kph-to-m/sec-conversions by dividing by 3. Just three. When calculating in my head. The error is about 17 percent but it's enough to estimate the energy that provides a hammer to a toe. Same with pi. For estimations, it's 3. Plus a little bit. In my calculator, it has eight or 15 digits after the comma. But this one is used only if precise numbers are needed.

Is there a calculator for gravity assists? I would estimate and assemble it for my own. But there's a calculator for all the inter-planetary transfers, even with some explanation. I think we are not the only persons who discuss that topic. So I'm sure this exists somewhere. Even with the extended error in these transfers (giggling orbits).
