The Eve & Tylo Challenge

[KAL 9000]

We all know how terrifying landing on Tylo and launching from Eve is, so I'll make a challenge where you have to do both in one mission! 

Challenge rules:

-Land on Tylo or Eve with ONE LAUNCH!

-After returning to orbit, land on Eve if you landed on Tylo, and land on Tylo if you landed on Eve with the SAME SPACECRAFT!

-Return To Kerbin 

----------

Your score is your mission time, in days, plus the amount of Delta-V you spent. So the lower the score, the better

You have done this already, right?

[Chabadarl]

With the smallest probe, the landing and takeoff are really doable and your challenge sums up to finding the best date with three transfer windows close to one another. 

Do we need to bring Jeb or some science tools ? 

[Foxster]

Also...can we use a mothership?

[Nefrums]

I guess the intent is to not allow docking? In that case this is a unique and very difficult challenge.

[KAL 9000]

No docking, at least 3 Kerbals

I did this a while back, but I forgot to take screenshots. It is doable!

You have just upped the stakes a lot. Just getting three Kerbals off Eve is tough enough, getting them over toTylo and down/up and back to Kerbin sounds really tricky. Or even just getting a craft down to Eve and back to Kerbin with no docking is a tough challenge. 

I'll have a go when you prove you have done it

Of course, I'll do it again with screenshots and a new craft (physics might have changed since 1.0.5 when I did it). I did use ISRU and mods though, but no Alt+F12 or Hyperedit! Oh wait, did I say no docking? Sorry, I just saw someone else ask about it and brain farted. No, docking is allowed, it's just that any craft you use have to be launched together. But still 3 Kerbals minimum.

[Foxster]

What do you mean by "return to Kerbin"? Back to orbit, crew on the ground...?

[KAL 9000]

Crew on ground.

[Rayder]

By my estimates the craft needs at least 20k dV. Very challenging indeed if it must be one launch...

[KAL 9000]

It is! I used Behemoth Aerospace and a 10 meter wide rocket was barely big enough!

[Laie]

If your vessel can get from Eve to Tylo and back home, you could as well land on every other body. Insofar this is like the Ultimate Challenge, only without the tedium of actually visiting every single body.

Forgive my haggling, but will this really be necessary? All this proves is a tolerance of low frame rates.

[KAL 9000]

Actually, launching everything you may need on one rocket is a major engineering challenge.
