  1. Inline Ballutes Slow down your rocket in an upper atmosphere. Ballute = parachute + baloon = an alternative to a heatshield. Sample usage: Duna aerocapture and aerobraking, Kerbin reentry for reusable stages etc. Dependencies: stock aero = none. FAR: Module Manager by Sarbian and RealChute by stupid_chris Suggested mods: RealChute by stupid_chris - especially when with FAR aerodynamics. Config for RealChute is already included in the mod. RealHeat by NathanKell - brings the shock heat in the upper atmosphere to more realistic levels. R
  2. Aerocapture is a great way to save massive amounts of fuel on interplanetary missions. Its main downside is that it's not possible to plan very well, as your final trajectory depends on your craft, your planetary intersect, your periapsis, and what you do during the capture. Usually aerocapture involves trial and error with a couple of quicksaves/quickloads. Below I describe a technique for more controllable aerocaptures. It is applicable to Duna, Laythe, and Kerbin*; Eve and Jool would require exceptionally robust designs with creative use of heat shields at least. Designing the cra
  3. Hi, Using the oft-recommended KSP Launch Window Planner (http://alexmoon.github.io/ksp/), I'm attempting to set up a mission that will take a very aggressive (totally non-Hohmann) transfer to Duna. The idea is to shave time off the transfer (and depart a good ~80-100 days before the planets are "ideally" aligned) by spending a lot more delta-v than would be "optimal". I'm about to unlock the ISRU converter and build out a Mun mining base with Extraplanetary Launchpads, so my thinking is "fuel is cheaper than time". (I don't want to time-warp through the long coast because I've got lots of
  4. First off, it's not my first rodeo in KSP. However, I found that one of my greatest challenges for interplanetary missions is designing a ship that is aerodynamically stable while performing an aerocapture maneuver. The primary reason for this is that rockets are naturally bottom-heavy, especially when launched from KSC. So while one can easily place an inflatable heat shield between the launch abort system and the command module, the center of mass will be so far back that the ship will tend to flip unless you add a ton of drag to the back end, in the form of literally tons of fins or more cr

  6. Okay - I'm finally getting to Eve and Jool, and I'm hitting a wall with aerocapture. I'm having ships simply explode. I've resorted to having ships just use lots of fuel, but that's making them large and unwieldy. Would be nice to have some ideas on how to best accomplish aerocapture, as well as good altitudes - is the KSP wiki still accurate on this? Thanks for any help you can give.
  7. Hi there, Just a quick question. Is it possible to aerocapture a vessel with a direct transfer from Kerbin to Laythe using heat shields? I've been trying this all night long, but the vessel keeps exploding the minute (nay, second!) I enter Laythe's atmosphere! Below you'll find a picture of my vessel. As you can see, I'm coming in hot (orbital velocity is + 8000 m/s). The vessel consists out of 5 FL-T stacks with 5 large heat shields. Do I need more heat shields? Or maybe the larger, inflatable one? Or is it just impossible at these speeds. If I need more heat sh
