Super Eve challenge

[Robonoise]

You have probably run a mission to Eve and have had trouble escaping it’s massive gravity before. But what happens when Eve becomes a super earth and has 10x the mass? Your challenge is to launch a rocket from super Kerbin, achieve orbit, and go to super Eve, land, take off, and finally return to super Kerbin. 

To simulate the high super planet gravity, hold the alt key and press the f12 button, then go to cheats, click on hack gravity and set gravity to 10 (for an easier challenge, set gravity to 5). 

To measure your progress, use this rubric:

Took off from Kerbin successfully...1

Achieved orbit of Kerbin...2

Set course for Eve...1

Orbit Eve...2

Land on Eve...2

Take off from Eve...3

Set course for Kerbin...2

Return to Kerbin’s surface...1

Total points possible:15

Add up your points and tell how you did!

Considering that even orbiting Kerbin in 10x gravity is barely possible, Eve and back would likely take a computer more powerful than any existing today.

To be fair the challenger never explicitly forbade k-drives...

Exactly, go nuts!

Remember, I said you can do this too if you like.

Ok so here's the thing. Eve gravity and atmosphere basically makes 10x Eve launch difficult to even start. Especially if we're not launching from the tallest mountain on Eve.

I'm curious whether a Vector engine can even lift off at Eve sealevel?

Again, you can also use x5 gravity. Also, you can use all the mods you want! Use as many engines as you can, that’s part of the challenge. Go nuts and think outside the box

Well then what stops me from just flying a K-drive there, landing, pointing up, and flinging myself back at Kerbin at relativistic speeds?

Nothing! It just takes some fun out of the challenge. But if you want to take that way out, go ahead.

Challenge needs some rules to be challenging... If everything is allowed, everything is easy.

When I set rules, people say things like this:

When you dont set rules people say things like that. When you set rules people will see that it is forbidden to use cheats/exploits

Show us how you did it @Robonoise. It is customary for those presenting a challenge to show that it is a possible one...

Not often, as my experiences go...

Actually this is much easier than what it looks, when using the proper technology to do it.

A planet with a so dense atmosphere is never a disadvantage, because increase the break action force (advantage 1) to enter in atmosphere which allow almost a zero delta-v to land from Orbit.

And with very simple technology like electric fans or air-balloon type you can very easily go until 10km or 15km height, without using the main engines and then just light them and go very easy to orbit again.

But this breaks the logic of using normal rocket engines which are not suitable for that.

You've gotta electric fan up a rocket with more than enough DV for an IRL direct ascent moon mission and 17+ G TWR. In 17 G. This is a very hard challenge.

Yet doable, as said by @pmborg. Also, a thick atmosphere means better performance from parachutes! Now Duna in 10x g would really be a challenge!

I have done a basic test, with a small ship at the 3th attempt made it, (in a Kerbin of 10G) and got it in Orbit at 7500m/s at with AP: 452km, then just run out of fuel, I need a 4th attempt to do all steps of the Challenge for tomorrow night.

Actually 4th attempt, Kerbin Orbit:

 

Hope tomorrow night have more time to do all mission and upload the video.

Cheers!

Great job! Just want to remind everyone that there was no rule against assembling ships and landers in orbit of Kerbin.

Of course everything is doable if all mods etc are allowed. I mean you could just mod in an engine with 1000000isp and 100000kN thrust and that's it.

Now you guys are getting it! But remember, the more you mod, it becomes less of a challenge.

[pmborg]

Both engine values are in the image, provided yesterday, engine provided by KSPI mod @FreeThinker:

• Not 100000kN  = 58,320kN
• Not 1000000isp = 594,603 ISP

Please note that about the mods, nothing is refereed as a limitation or even as a penalty points.

So until now at least I have:

• Took off from Kerbin successfully...1
• Achieved orbit of Kerbin...2
• Set course for Eve...1

Points: 4

• But as a side note the secret is not the engine, that is just a detail, I have done it, with 3 different engines types, this engine is not even capable of get off the ground.
• No boosters were used
• Vehicle until now is 100% reusable.

Ship "Eve5":

Landed on EVE, but during descent the Radiators Broke from air stress, because the ship got initially at 60,000m lateral deceleration.

I think that I will need a "Eve6"

[Robonoise]

At least you got there. Great job! Best of luck on the easiest part, getting home!

Thanks:

Added here an intrigue question, I have done it and only used 33% of engine power!

I am uploading the video of takeoff:

Looks amazing!
