Eve attempts

[-RanZ-]

Fire first MK-25 chute and then others (if needed). Drag with Mk-25 is smaller, it didn't broke my 140 t ship. 12100 dV is good, report from what altitude you get to orbit.

Video of my ascent is here:

I did some extensive testing last night and the problem was I was opening all chutes at once, if I stage them and do like 6 at a time it works fine and doesn't rip my craft apart. Landing legs I will just have to deal with, I land at about 8ms/sec and it crushes the landing legs so hard most do not retract on ascent... not a big deal though as they get jettisoned almost immediately so I think I will just go with it. I am going to launch it tonight and dock it with my RIPV Mk II(Reusable inter-planetary vehicle) and get Jeb sent off to Eve!

At long last, success!

My first working Eve return mission took two launches, each in the 700t ballpark-- one for the giant rover/lander/ascent vehicle, and one for a huge transit pusher stage to get it to Eve and back. Landed, drove up a mountain, and safely got Jeb back to Kerbin.

As is usually the case, though, once you've actually succeeded, suddenly all sorts of optimizations become obvious. The second attempt used a similar design-- but the rover assembly weight was cut in half, room for a tiny Gilly lander was found, and the entire assembly was able to cram into a single launch with a weight of 590t. Jeb made a second trip to Eve, drove up a different mountain, and returned to orbit where he made a daring spacewalk from the remains of his lifter to the main ship. A side trip was made to Gilly so that Bill had a chance to stick a flag in something as well, and then everybody returned home safely. Or at least that was the plan... thanks to a bit of over-engineering, the two actually ignored orders and stopped for tea at Minmus on the way back as well.

The drive-up launcher concept definitely seems to be the way to go, though. Through a bit of luck, I decided to try it out shortly before .22, so I managed to accidentally replace legs with wheels at just about the exact moment when legs become problematic on Eve. The tires are almost always all flat on landing, but that's one of the few things a Kerbal can fix in-flight. In theory, a vehicle like this should be more than capable of a sea-level landing and return, but the cross-country uphill drive would take a while.

Pictures of the adventure later. One more quick flight to make to plant a flag on Ike, and I can finally say I've landed (and returned) a Kerbal on everything, in career mode.

An Eve accent? What's it sound like? I can do passable Scottish.

Yes, since landing legs are "broken" as far as Eve is concerned, one might as well go with landing on wheels and then use the driving-up-a-mountain method. Congratulations one escaping Eve (and reaching all other bodies). Have some kerbal snacks.

Managed an ascent from Eve from 400m altitude, with a 120 tonne lander (aerospikes) with a 0.8t lander can on top. It barely made it to a 115x120km orbit before running dry.

The entire thing was launched as a single 1600 tonne rocket, to bring the lander to Eve as well as a tiny fueldump to rendez-vous with for the return home.

That was in 0.21; now the landinglegs dont stand a chance anymore, and i can't figure out how to mod the CFG parameters to get them to work.

I tried once, I already knew it was unable to reach orbit, but I didn't need anymore that probe xD

[Death Engineering]

Made four landings there which had the intent of returning to orbit, of which only two were successful. The last successful return was two kerbals in the mk 2 Lander can. I'd like to try three or four next using a "cluster" of mk 1 Lander cans now that I've realized their low mass. Time for attempt 5...

[FlamedSteak]

I've never been game to try it.....but after I rescue Jeb from Laythe, I'm going to attempt it.

I'm going to assemble three vessels in LKO, one with a command pod and fuel for Eve injection. A second to carry landing and ascent stages and a third module for the return journey.

[-RanZ-]

I just attempted it and I greatly underestimated my TWR needs.... TWR on EVE != TWR on Kerbin lol. I am going to try from a higher mountain and hopefully salvage this mission else I need to start over again!

[thereaverofdarkness]

I made a launcher that when tested on Kerbin was able to take to orbit a payload that I was then able to land back on Kerbin and take to orbit. The whole craft was able to survive parachute deployment on Kerbin. I'm hoping it will be able to descend into Eve and launch back out but I haven't yet managed to bring it over there. I have it in high Kerbin orbit and am having difficulty refueling it because it seems to have inherited a glitch in which it slowly gains rotational acceleration while I am trying to dock another craft with it.

Back in 18, I did a rescue mission to eve. Managed to successfully rescue Lars after an error put me into too low of an aerobrake orbit. Since it was my favorite Kerbonaut stranded, made a little movie for it using previous versions as kind of a really crappy tech race thing. Was a way to kill some spare time.

Be warned, cheesiness is strong with this one... Also, I had upped the engine fuel efficiency some on lander simply because my comp at the time didnt like really big rockets...

I have found that TWR 1.74 on Kerbin is equal TWR 1 on Eve.

[-RanZ-]

I am probably going to have to send a rescue mission, my final stage is about 600m/s short to circularize orbit and only has a twr of .99

May I introduce you to a new activity? Eve Extreme EVA:

http://forum.kerbalspaceprogram.com/threads/59653-Eve-Extreme-EVA

A TWR of .99 is perfectly fine to circularize btw.

I have only ever landed one thing on Eve, a single lone unmanned rover. An odd planet, it is...

[Ghost13]

Had anyone did successfull mission to Eve in 0.22? What is about landing legs? They no longer support heavy craft properly?

[Hodo]

I have attempted this recently... with a probe, using Remote Tech 2, and the signal delay ON, so I have a delay of 74 seconds. I have successfully landed the probe there.

This lander worked well. In fact it was a bit of an overkill as it was based on an 0.21 design with weaker 48-7S engines.

Bottom tank is for plane change and deorbit. An landing stage with command module with an rover below.

I had to take off again to decouple the rover as the landing legs compressed.

Landing legs helps even if they compress so the engines touches ground as they soften the landing

[Agent86]

The first time I sent a dude to Eve, I had no idea how thick the atmo was and the strength of the gravity. My first rescue vehicle was pitiful, and I spent my ascent and transfer engines just trying to ascend, failed, and parachuted back down. My second rescue vessel broke apart on descent. My third rescue vessel broke apart as I was orienting it for a circ burn. So close. The guy survived that crash too, and is still there on Eve. I've assigned him to be a permanent colonist now. By the way, his name is Jeb.

[Col_Jessep]

You can add 1 vote for success and remove one from failure. I landed on an ant hill of 2145 meters but made it back with EVA thrusters. I think this was probably the most fun I had in KSP so far... =3

Balloons and EAS-1= sensible.

For some reason, it seems to have cracked through the surface of Eve..

Hopefully the hybrid engines in .23 wont make it less of a challenge ... ?

Hybrid engines? I think you will have to show me the source of that.

<p><strong>Chad (C7):</strong> I spent this week working on new module additions and testing the implementation of new features. The landing gear are now steerable and tweakable in the editor. So you’ll be able to steer and taxi aircraft. I’ve also added multi-mode engines. These will allow for engines that are air-breathing and transition to rockets, or any combination thereof. They’ll each be able to have their own FX, engine performance stats and propellants.</p>

But it is all around the news!
