Mr. Peabody Posted October 27, 2018 Share Posted October 27, 2018 O.K. Thanks for the info. Would it not be simpler to land and refuel on Bop or Pol before heading to Laythe? That should give you the needed DV to lower your orbit around Laythe for a safe re-entry. Link to comment Share on other sites More sharing options...

Depends on your shuttle, how much fuel/dV you can carry around in your orbiter and if you actually want to use an ISRU (I don't^^). Getting back into orbit after landing on laythe will still need ~2800m/s, so if your full fuel orbiter without any cargo got a dV of ~3400m/s you can still not use 1000m/s (probably more) to slow slow down into a nice low Laythe orbit or you will be stucked on laythe after landing. Well, if you can refuel on laythe again, it would be fine anyway. Link to comment Share on other sites More sharing options...

In my opinion the reason is that your orbit is highly elliptical, and its a pain around Jool because you have to understand that you are going extremly fast when below Vall's orbit. It's all about lowering Ap, and best way to do this is multiple flyby around. I checked my screens and I touched Laythe at 2700m/s on the first landing.

I used Tylo for most of my flybys to slow down but probably that's actually the mistake because I cannot lower my Ap down to Laythes orbit without my Pe disappearing within Jool. I'll try some more gentle flybys around Val, maybe it helps Link to comment Share on other sites More sharing options...
sturmhauke Posted October 27, 2018 Share Posted October 27, 2018 You definitely should practice your Joolian pinball. There are two ways to get in, around, and back out of the Jool system. One is to carry several craptons of excess dV, and the other is mastering gravity assists. Here's an example of a multistep maneuver I did on one Jool mission: Spoiler (full mission here - https://imgur.com/a/8ZSZH) 1. Trident SSSTO (that's a Seaplane SSTO) enters Jool system from the top left, along the blue solid conic 2. small course correction puts Trident on a gravity braking flyby of Tylo, starting along the purple conic on the left 3. flyby sends Trident inwards towards a low pass of Jool (slightly above its atmosphere) along the green and red conics 4. Oberth burn at Jool periapsis boosts Trident back up to a Laythe intercept along the blue and yellow conics 5. Trident performs aerobraking and capture burns at Laythe (not shown). I don't have screenshots of that, but I think the initial aerobraking velocity was under 3000 degrees - a bit hot, but manageable with Mk 2 and 3 parts Link to comment Share on other sites More sharing options...

It is more like: put a rocket engine on it and fly it into the atmosphere? Exactly. You only need to recover the hab module, the solar array can be sent to burn in the atmosphere. 14 hours ago, 4x4cheesecake said: Well, I'm getting tired of burning up in Laythes atmosphere Regarding this - I believe that the solution is as everyone hinted - limiting the entry speed by performing a few gravity assists in the Jool system. That's pretty much the purpose of STS-3T, learning how to do those Link to comment Share on other sites More sharing options...

Probably, I just used a too small SMA. Thanks everyone for the great hints :) Link to comment Share on other sites More sharing options...

Thanks everyone for the great hints Also you can encounter Laythe and slightly aerobrake in the higher atmosphere during multiple times, this will lower Ap and you can capture later once your orbit is less elliptical (like my STS Eve 1).

Ozelui Posted November 1, 2018 Share Posted November 1, 2018 We choose to go to Mun, not because it's easy, but because michal.don tells us to do so! (And because of the badges!) Not much time for KSP lately, RL gets in the way whenever I try to build something . Fortunately the only meaningful change to the shuttle for this mission was emptying some OMS tanks. Other than that, I added a couple of solar panels and fuel cells just in case, and replaced the DTS-M1 antenna for a HG-5 to look closer to the real thing: About the reentry, the Dessert airfield or the KSC were too far behind my re-entry point so I went the long way around. The altitude profile is pretty much the same as a skip re-entry (see below), just not leaving the atmosphere at any time: STS-5T report here Craft file here Spoiler Mod list, however the ship is stock+DLC, no modded parts involved.

I love this And I'm very glad to see the first one to come to claim the new badge Your entry sure counts, great gliding capacity and a pinpoint landing, I'll probably never grow tired of seeing those. Good job! And the Eagle landing spot is just right, too Congratulations on being the first 5-level-certified test pilot! So I should design the new mission now....

4x4cheesecake Posted November 2, 2018 Share Posted November 2, 2018 So, while working on the final payload design for my Jool STS - 1, I came across a little problem: Spoiler The blurred part contains my atmospheric exploration aircraft, I just don't want to spoil the design already As you can see, the remaining space in the cargo bay is pretty small to fit in a surface outpost but I have some space left below the aircraft....so am I allowed to split the outpost in multiple modules, assemble them in low laythe orbit and put the whole outpost back into the cargo bay to land it on laythe? Obviously, I need to get rid of the aircraft before I can do this but that's fine with the rules so far Link to comment Share on other sites More sharing options...

Hm...maybe multiple small habitats will actually help a bit.

Yeah I'll try that Never thought about building along the Y-Axis and put the stuff next to each other or at least not for the orignial design... the 'split' version actually requires exactly this type of design, I have no clue why I haven't thought about it earlier xD Well, sometimes you lose the forest for the trees^^ (and finding a translation for an idiom is quiet an adventure ) Link to comment Share on other sites More sharing options...

If you don't decide for a redesign, orbital assembly of the outpost is completely fine, too.
