  1. What if the bodies are not equal mass? That could put the barycenter inside the larger body SOI.
  2. Did my first Tylo landing yesterday. Went smooothly. First I messed my transfer from Kerbin, but got enough fuel to get my mothership in high-elliptic Tylo orbit. I sent initially some tankers so no worries. Got my Tylo lander with a tug in a 30km circular orbit bit after. Crew transferred in smaller lander as the mother ship is a bit low on fuel and the small lander is able to refill at Tylo-tug. Then to the business... First attempt from 30km orbit went kaboom. One continuous burn aiming retrograde beginning from 30x30km didn't do. The lander had plenty of fuel and speed left on ground impact. So not enough TWR I guess. Lander descent stage is on single aerospike, some drop tanks. Separate ascent stage with single terrier and more drop tanks. Alcor pod on top with the usual crew. Changed plans and managed to land by aiming thrust below retrograde to gain more time to burn through all the fuel. That did it after some tries. Jeb planted a flag. The he was not able to climb the ladders to the top of a tank, even though I had tested that on the pad. Then I figured out to raise one landing leg and tilt the craft and Jeb got back to pod. At ascent, I then realized just after take-off that my ascent stage was drained. Probaply the tug eptied it through a docking port. So nothing more to comment on that ascent. So reloaded a save, refilled the lander, and eventually managed to land again. Planted "second" flag. Then I did the trick with the landing leg and got ready to take off. Landing had cutted my fuel margins thin. I had to stage almost immediately after take off and switch to single terrier ascent engine. And then I ran out of fuel later. Fired monoprop. Bailed out Bill and Bop with jetpacks to safe orbit. Jeb didn't have enough time to jetpack to orbit. I decided that the ascent was not so optimal and there was possibility to success. So I reloaded a save. This had nothing to do with the fact that I hadn't refilled ALL ascent stage tanks. So refilled two Oscar tanks also. I guess that I lose some delta-v on ascent as I can't aim the prograde when it's near horizontal like on Mun ascents. I have to aim higher to gain altitude. Not enough TWR here also. Then I did a new descent, with just slightly better piloting and all full tanks to begin with. Planted "third" flag. This time no landing leg trickery as I was on nice slope. Adjusted staging to get rid off landing legs and empty tanks right at take off. Had to switch to terrier again too soon. Aimed for hopefully better trajectory, fired monoprop almost immediately to get rid of weight and optimize delta-v. Again ran out of fuel. Bill was ready to bail out. Then Bob right after. Also Jeb managed to get out in time to jetpack for orbit. Now all three crew members are orbiting in suits in safe altitude. I plan to pick the guys with the small lander and then proceed with the mission as usual. Now thinking it I should have used the tug for the initial descent. It at least has some tiny amount of fuel left. Also firing the monoprop right at the beginning of the descent instead on ascent might have gained something. Anyway, the flag is planted and crew is in safe orbit, so I call my first Tylo crewed landing a success. Next on schedule is testing out my first Laythe plane, arriving in few days. I expect nothing to go wrong with that.
  3. I got the smallest stackable battery exploding before circulation burn. Batteries are inside stock fairing, and remain ok while in there. Temp about 280C. When fairing jettisoned, all is ok for about 15 seconds. Then the temperature just runs aways. My computer doesn't have big enough numbers for the heat. There is some DMagic science stuff attached, also with MechJeb AR202 case. Sometimes the mechjeb case just flickers between 0C and infinity. I found this link: http://forum.kerbalspaceprogram.com/threads/126455-Warning-Modders-Parts-Really-Low-Mass-Plus-Large-Surface-Area-1-0-3-1-0-4 Mechjeb case is very low in mass. I fixed that manually. Didn't change anything. Things got less explody when I removed FAR. Oh, and dunno if it relates to this problem, the temperatures of the craft just does not change after deleting FAR. Something else is weird here too. There is hot radiators and hot engine but no cooling or heating anymore. Some other crafts perform normally with FAR in this same save, launched before 1.0.3. The problem case is launched in 1.0.4

    Hello all

    First post here. I have been lurking around since 0.22 so maybe it's time to say hello.
