Sage Grimm posted:Had my first landing and return from Gilly. That last stage managed to get back into a low polar orbit around Kerbin (not enough fuel to adjust the plane much without burning in the atmosphere). I sent up a capture rocket to nab it and bring it down behind a heat shield since it wasn't built for atmospheric landing. Felt pretty good! You could also use a trick from Real Life rocketry: spin stabilization. Basically, aim for the heading you want to go, make sure you're really stable, then turn off SAS and get a good healthy axial spin going (Q or E), then fire up the engine. This will distribute any off center thrust and while it doesn't cancel altogether, it should be manageable for short/medium length burns. Doesn't help too much for landing, but Gilly you should be able to land with just RCS or really really short burns--once you're in orbit you're only doing 30m/s or so if I recall.

The landing is pretty much what you said, I'm going to be turning the limiter down low so I can easily damp out the swinging. Didn't think about the spinning, though, I'll give that a shot in the Hohmann transfer. EDIT: Spinning kind of worked until it didn't but I had plenty of deltaV to spare. Made it down gently to the surface by bopping up and down, barely giving it any juice. I think what happened was in order to make a more squat base-like structure I turned the science lab on it's side then stuck a tripod engine setup underneath, totally unbalancing the thrust vector. It wasn't a big deal when it was on top of much heavier stages but when it got down to the last stages (both with <1 TWR), the flaws emerged in force. Scientist condemned to never return to Kerbin again.

If you have multiple engines, and are using Mechjeb, check out Mechjeb's Differential Throttle - definitely saved my bacon a few times. Differential throttle made landing this thing a breeze

Differential throttle, Throttle Controlled Avionics, Davon avionics and one or two more I can't recall have been around for a long time (some of them years). Every time one of the older ones slips down the mod pages or isn't maintained for a while, a new one seems to pop up.

Wow, played v0.16 - v0.90 would have spent many fewer days tweaking VTOL and Space Shuttle with something like TCA, that really turns on easy mode when you accidentally throttle up too fast and your space station goes in to an uncorrectable spin

There are mods to manage throttle for off centered thrust?  I have made so, so many lopsided lander designs where I was tweaking the engines manually. Sometimes mid suicide burn

Doesn't the hangar adjust the center of thrust marker if you manually neck down the engine in the VAB? Just get it roughly under the COM and you'll be fine.

Yeah basically that, for me it's really only an issue with large vtol rovers. Or landing surface colony outposts.

So I figured out the problem with the parachutes (it now takes much longer for a parachute to fully deploy and begin slowing the craft, which I guess is better from the perspective of pulling g's), but now I keep running into something which seems to be a real pernicious bug. I think it might have something to do with loading a save, but most of the time my heat shields won't use up any ablative material, there will be atmospheric effects and a build up of heat, but the speed of my ship won't be effected. It'll continue to gain speed as if in space rather than slowing down as it plows through the atmosphere. Jettisoning the attached heat shield suddenly makes the ship start slowing down, but is obviously a very short term fix as the ship tends to overheat and blow up before slowing down enough. I looked around to see if anyone else is having this problem, but couldn't find anything. I'm playing completely stock and it seems like a really huge bug, even for KSP.

Pic of your landing stage with the heat shield attached? Sounds like you have it on backwards or clipped into the part above it or something.

Its really gently caress off heavy. The dynamics of atmospheric freefall is that your terminal velocity will be lower for a lighter object when it has the same exposed cross section. That its affecting your descent deceleration so much means its a not inconsiderable amount of your return stage weight. Your options are drogues, make your return stage less fat, make your return stage draggier, reconsidering approach to get a longer descent, and or any combination of these that doesn't involve blowing up. e. Maybe also misunderstanding the density changes as you fall and you are coincidentally dropping the heatshield right before you hit the soup. The altitude around 18k-22k is the soup and where a lot of your slowing is going to come from. The goal of most reentries is to survive blowing up in this region while slowing down enough you are on track to open chutes before you get too close to the ground. zedprime fucked around with this message at 13:26 on Aug 18, 2017 |

Nalesh posted:What's the first area that has something like that? Also what's the offplanet ship building mod of choice nowadays? It is randomized on your save but I generally find that minmus should have some, you'll have to scan for where exactly the good concentrations of it are though. I used KSILS and KSTS together and it appears, once you switch to the craft in question, to update the crew life support statistics properly for anybody you sent there with KSTS. But I don't know how robust that is and I would exercise caution when doing it, save beforehand and check immediately. The rest of KSTS works perfectly though and you can use it to both launch craft into orbit and resupply orbital infrastructure with fuel and supplies. MKS appears to come with some sort of extraplanetary launch pads compatibility as well as some other kind of in-situ building system but I don't know exactly how it works, documentation remains iffy for MKS.

Is there a good way to get an assload of exoticminerals back to ksc from another spot on kerbin? I was originally just gonna Bon Voyage it, but it turned out to be on an island so I can't. Would prefer something like the old USI drone system.

Build a rocket and suborbital jump it is the most time effcient approach. Or build a plane with rocket boosters and suborbital jump that there and back.

My team is working on some design explorations for a company's new brand, and we're doing a bunch of images with space and rockets. Is there a single, iconic KSP rocket design I could send to my art director to slip in there? (I can't do anything too gonzo like 1000 boosters strapped to a MK1 module).
