    Funnily enough I was working on something like this over the weekend. Only really hits the first objective and it's not very practical but I had a lot of fun working on it so I may come up with something specific for the challenge later this week.

     

    Aside from the tanks/tank intake on the engine block, most of that is empty tank. So... yeah, if you want bouyancy you really do need a hell of a lot of empty tanks.

    OMG Porco Rosso Plane ? Excellent xD

    Yes, mine was set to ALT+F8 by default, which worked fine!

    Unfortunately, teleporting my craft from Eve orbit to Kerbin surface doesn't mark the mission as complete. 

    My developer debugging brain tells me that that means that whatever I did during my mission that broke one of the requirements of Under Pressure, occurred before my craft returned to Eve orbit from the surface. So I could work back further and further until I actually complete the mission, then zero in on what I did specifically during that phase of the mission that might have broken one of the mission stipulations. Does it sound like I'm on the right track with that logic?

    I mean, using the cheat menu, couldn't I just slap a 2-person lander can onto an 8-person crew carrier, teleport it to Eve, then teleport it back to Kerbin? 

    Yes you are on the right track !!! :)

    Iirc, i think i tried to do the direct cheating from kerbin to eve and back and that didn't ended the misson.... :(

    But to be tested, maybe that could work for you :)

    Really annoying bug...

    gameplay time of ksp2

    Hi @ralanboyle and All :)

    Here is my entry for this challenge... 2.44 Tons with Jebediah onboard.

    I already played 858 hours on KSP2.... and a lot more on KSP xD (ok ok i'm a big fan of this game..... lol)

     

    That was fun to play without reaction wheels xD

    Did you ever figure this out definitively? We're not supposed to launch from Eve surface to orbit, then make the entire trip back to Kerbin without a pusher ship, right? That would require an impossibly huge rocket...

    I just completed this mission yesterday, and didn't get credit for it too. I'm thinking it could be one of two things. 1) My ship didn't have any bone-fide command pods in it. All ten kerbals were in rover chairs. Maybe the game doesn't could that as a 'vessel'? or 2) I realized after I got my ship back into orbit, that I used different size docking ports on my lander and my interplanetary pusher, so I had to build a new pusher ship and fly it out to Eve to pick up my Kerbals. Maybe using a ship that was launched after the Kerbals were launched caused the game to see it as 'not the same ship'?

    Regardless, I hope the devs sort this out eventually, because it's pretty frustrating to spend three weeks designing a ship for this mission, only to have it glitch out and not mark as 'complete'.

    If you have a saved game while back in Eve Orbit, you can use the cheat menu (alt F12) to teleport your ship with the ten Kerbals on the rover chairs on the surface of Kerbin just to see if the mission is 'complete' :)

    Just saw your Eve SSTO vid @astrobond - that's incredible! Would never have thought that was possible. Wonder if you'd be interested in this? 

    So far one brave soul's posted a brilliant, enormously complicated solution (I'm in awe), but no one's yet figured out the simpler way of doing it :) (Still tricky, but doable.)

     

    Thank You ;) That was a long time ago lol, I made some tries on KSP2 for a SSTO from Olympus Mons on Eve, but from 3000m, that's really hard... not found a solution for now... but i will try with darts on first part ascent xD

    Your challenge is excellent !!! I only play KSP2 now, but maybe i will try ;)

    picture of landing legs

    1 hour ago, KincaidFrankMF said:

    Btw, is it just me or are fairings doing literally nothing at this point? Likewise cargo bays. Neither seem to help lifting off from Eve, where aerodynamic costs are really obvious.

    Not only cargo bays don't help, but actually they induce a lot of drag !!! I wanted to do science on Eve, i ended with all science parts on a decoupler to let them on Eve after doing the science  and getting the datas in the command pod :)

    Tried also fairings, but no help for me too... Using just good aerodynamic parts are enough, and lighter is better ;)

    For landing legs if the lander tends to tip over , i have "home made" landing legs with xs truss and small heatshields at the bottom, really strong and no problems  :)

    Really awesome designs here. I've struggled with the landing plan. What's the preferred strategy here? Parachutes and/or powered touchdown? I don't see any landing legs. Landing on the heat shields? Decoupled legs?

    Thankyou @steveman0 This is only the version to test to go orbit, i use only Parachutes, you must keep all the fuel for the ascent :)

    I use landing legs that can be decoupled yes, same for the heatshields, they are decoupled before landing to save weight for the parachutes !

    I also use heatshieds at the top of the lander to be autostable on reentry, and i have also twisted a little the upper shields to do an autorotation to keep parts not too much hot ^^

    Actually, after a bit of tweaking I can do better - 144t, made it to orbit with 600dv spare.

    I start the gravity turn much earlier - around 4-5k but keeping it very gentle.

     

    Awesome Design !!! Good idea to use exactly 10 seats with 4 parts,  lighter than my 11 seats two parts :) Really optimized Lander.... Congrats ;)

    Ah, grumble seats. My guys travelled in comfort :sticktongue:

    Did a bit of experimenting, and I still can't make vectors come out better than darts - even with the improved aerodynamics they're about 350dv short. Could just be a less efficient setup though - adapting a design isn't the same as building it that way from the ground up...

    Hmmmm... yes, Tourist Class for Kerbals is better !!! I just tried a new 151.58 t version, with Hydrogen tank Full,  30  degrees prograde at 20km and... 400m/s left with this big boy full of Kebals, SWERV is awesome and Vectors boosters definately good in aerodynamics :)

    You mean you have a 154t Eve 10k launcher without grumble seats ? WOW i hope you will post a picture of your lander :)

    Here is another tip i use for my eve Launchers:

    I use two small fins with some angle to separate last boosters without colliding the core stage... lighter and more efficient on Eve than sepratrons :)

    Hydrogen tank tunning :)

    Excellent thread :)

    Here is the last version of my Eve 10K Lander:

    0s9ZHMO.jpeg

    144.85 Tons with 8 Vectors aspargus and a SWERV, Ok From Eve Sea Level with about 300m/s left in 100x100km Orbit :)

    Ascent is vertical until SWERV stage at about 20km, then aim 40 degrees inclination, and prograde until AP 100km.

    (Edit: Hydrogen tank set to 5.6 t of fuel)

    @astrobond What? Are you serious? I didn't even know that body temperatures are even simulated. What you are trying to say is that the wheels explode because the sand is too hot? Will definitely give this a try.

    I think the ground is muddy, so when it is not frozen, we are stuck and the landing gears explode when landing or taking off !!!

    What did you do in KSP2 today?

    Lastly, I'm kind of surprised by the choice of the Mammoth over the Vector for your ascent engine.  I had thought that the Mammoth's worse ISP curve would have rendered it impracticable despite its better inherent TWR, but I guess I was mistaken!

    Thank you @herbal space program :)

    As you can see later in this topic, I made a new version of this Lander, with... Vectors lol ! And yes, this is a better choice :)

    I did this whole mission but did not get credit.  Is there something specific you need to do.  I was very sad, spent since Jan working on it and didn't get credit when I pulled it off. 

    Hi @Destinesta, yes there is a bug in this mission, sometimes you do not get the credits, happened to me too :( 

    If you saved your game while back in orbit around Eve, you can try to reload from that file and go back to Kerbin, or you can  use the cheat menu to teleport your ship from Eve Orbit to Kerbin surface  to end the mission with rewards :)

    Welp, I made a ship that can get to Laythe, land, and then circumnavigate the planet in airplane mode before returning to orbit and then coming home. It works on water and land so I should be able to complete this challenge. Unfortunately, the game is having trouble recognizing where the ground is on Laythe, so when I land 9/10 times it slightly clips into the ground and crashes. The other 1/10 times I can land but then the Kerbal cant move around in EVA because they are floating above the ground. Then the plane clips into the ground again when the Kerbal boards. I can get around most of this by landing in the water and then driving to land but the landing gear immediately clips into the sand and causes a crash.  Frustrating, but I guess I'm gonna have to wait to run the challenge. 

    Hi @ralanboyle, I found that if you land, drive or EVA at the end of the night or early in the morning, the ground is safe, like if the temperature is taken in account on Laythe...

    Hope this help :)

    Added link to MK2 Version of the Rocket

    After my first Mission Report of "Under Pressure", @magnemoe wrote: "Impressive, but was they in tourist class the entire trip? "

    Hmmmm... Ok... 

    So i made a new rocket, with Tiers 3 parts, more Science,  a lot more snacks, and NO External Command Seats !!!

    Here is a link to the craft:

    excellent job!!

     

    But now,  im trying to figure out, what the upper heat shields are attached to?    (the ones for the desenct to eve surface, above the rocket)

    It kind of looks like they are attached to solar panels, but that cant possibly be strong enough, right???

     

    Thanks!

    Hi @CFTeague2 and Thank you :)

    The Upper heat shields can be attached to Radials Decouplers (TT-38K) using xs long struss (ST-XS-4) or Tubes (TOOB-000) for better temperature resist but harder to use in VAB.

    In the first version of my ship i used small panels (SP-S06), but that was not as good as the other ones :) (too much parts, weight and can overheat)

    Hope this help :)
