Have you already tested if it will make it to orbit? I'm actually refining it. I'm planning to release some of my designs someday. But it's not that hard to rebuild if you have a look at both videos

Please

Hm... Helicopter....

Ok, would like to see that I think a balloon or electric helicopter would be good on eve

I could land at sealevel and then jump to my launchsite to refuel and get back, but I think both does not count as sea level return A ground based isru truck would save you from having isru on the ssto. But a boat will force you to launch from sea level. Maybe an isru tanker plane would be an idea? That could easily reach ever landing site without the problems that wheels do have no eve.

And then drive to higher place, or what is your plan?

I've got these coordinates from Stratzenblitz75 at reddit: -25,-158.45 They work perfectly for hyperedit. Already the difference between 7500m and 6800m is massive... Sea level seems impossible without staging

Or you could use a tanker instead that harvests alone at Gilly and then refuels the lander in orbit. So it doesn't need to be moved around.

The lander and the mothership do both refuel at Gilly. The mothership then takes the fully loaded lander to low eve orbit. But since it's nothing special to move a ship from Gilly to eve, I only concentrated on the lander for now, the mothership might need resizing if it should bring the lander also to moho and so on for a grand tour. If you do a late suicide burn, the ship won't need all its fuel to descend. Maybe it can get from Gilly to low eve orbit by a lot of aerobraking with enough fuel to land safe. But since can't leave eve orbit alone after this, it will always need a mothership, so I haven't tested this. What speed is that on eve? It will vary. Yes, I just didn't want to wait the burntime it would take on my computer to get there on nervs with a 450part ship at almost no framerate but the mothership should be able to do this. The worst possible thing would be, that I need to add more fuel tanks. The video is just about the lander and the mothership should show that one is needed to pull it away from eve. For a second descend they both need to refuel at Gilly again. A mothership that can take the lander plus more than a thousand tons spare fuel for a second descend to eve would be... Gigantic

I think you will need a lot of inflatable heatshields and an insane amount of parachutes. If you either land on that heatshields or mount them on top of your lander, they could assist the parachutes down to landing. But you would have to check if this works, just an idea.

That's a really great collection! Thanks for all your work. I will have to add this soon... Did anyone find any issues or anything unbalanced in the tree?

That was a quick reply ok thanks

I'm thinking about doing this again... But in addition 100% reusable this time, because I now have this litte nice Eve lander Ps: am I still listed under "modded:" or do I read the list wrong?

Thanks! As I already wrote on youtube, your Eve SSTO video gave me the power to keep trying. My first designs were winged too, but it seems a rocket is the way to go in 1.1.3 This would take some time, my last grand tour took 3 month to develop and execute See: https://youtu.be/FXAzQk01vuw Maybe it just gets to heavy with the produced fuel, and then breaks when you return to normal speed/physics? Something I have realized now that I had more sleep than the last days: All my plane attempts were done from 6.800m and also this rocket was developed on this height. When @Stratzenblitz75 told me there is also a 7.500m launchsite, I already gave up plane designs and was happy that my actual rocket design worked from there. It reached orbit with ~10tons of fuel left, and I did not try to scale it down again. Maybe it can be downscaled to the half size or less. also a really small single seater should be possible.

If you want to switch between two or more nearby vessels in mapview and can't get a click on the desired one, you could change the type of the actual vessel in the rename window to something else (if it is not already), and then make this type of vessel invisible in the map view. At least that's faster than leaving the game to do this in the tracking station. Or is there an easier way? It also took a long time until I realized that you can use mirrored symmetry in the VAB and radial symmetry in the SPH.

I would have to check how much thrust they generate on 7500m. But it will be verry low above a twr of 1 I think

Yes, if I take it to a grand tour I will optimize it. The tug is just a quick build for the video, but it has 6 large drills and a large converter, so it can mine too partially refuel the lander. There are a lot of ways to speed up mining, in this model I was just after an all in one solutions that also looks and flies nice. Since I'm playing stock, I do not have a display for that, but profossi on reddit calculated these numbers based on the video: Property Value Unit Dry mass 279.62 t Propellant when fully loaded 1168 t Propellant expended 1165.3 t Propellant after reaching LEO 2.71 t "Mammoth" engine ISP (vac) 315 s Eff. exhaust velocity (vac) 3089.2 m/s Vac. ∆V when fully loaded 5079.4 m/s Vac. ∆V expended 5049.6 m/s Vac. ∆V after reaching LEO 29.8 m/s "Extra" propellant at launch 13.9 t Propellant margin 1.2 % That's around 1448tons on 8 mammoth - to calculate twr. You right with both, have realized it while uploading and have mentioned in the video description... But this was to much work to record again.

For sure there are many ways to make this more efficient. My goal was just to make it deorbit and orbit autonomusly at all costs. The margins are not as bad as they seem. I'm flying manually on keyboard. You just need to start the gravity turn at the right time. The chutes have to be packed in space unless you add ladders. But you can also use it as biome hopper by landing without chutes.

It was more than a hundred hours of really hard work just to build this one working lander, plus several hundred hours of experience in building SSTOs. But the result is worth the pain I think I'm at work right now and will have to answer this later. What I can say: 3. Yes almost all 4. Yes. You would need to add (disposable?) heatshields. No. Drop rate is around 35m/s on chutes only. 5. Ahm... Yes... But you can change this to the large drills to speed it up. The tug was just a quick build to have something cool looking for the video, since it is mainly about the SSTO. It will change if I really use it for a grand tour.

I don't know since when, but this ist stock in 1.1.3 There is a little round button left to the Kerbals "portraits"

Thanks Thanks it's absolutely stock. @magnemoe is right, it's a mk1 lander can, clipped into the mammoth. I think this kind of clipping is ok, since it doesn't give me any other advantage than a better looking. The thing would work with long ladders too The lander itself has 123parts, that's actually good to handle. The problem is the interplanetary ship, which adds around 350 parts. That means 2-5 fps Thanks to be honest... The landing didn't succeed in the first try... it might have been two or three or a million attempts Yes it has just 2 small ones. They are powered by 16 NUK generators inside the small bays. This lander has a payload of ~10tons - if flown correctly. So you can also put large drills on it. The only reason why I'm using the small ones, is to make look better vor the video

Turn up volume

The most time I feel like a mad rocket scientist Video will hopefully come tomorrow, it's all recorded, only needs to be cut.

Landing: works Isru: works SSTO: works All systems go the video should be there tomorrow. 1.448 tons with ~10 tons payload. I was even able to give it an Mk3 cockpit, but that doesn't look verry well, so I switched back some other pods

Wow! What an honour! I like the second one and will definitely take this with me on my next grand tour.
