    Made an upgrade for my Saturn V MLV. Payload capacity increased from 200 tons to 250 tons I am still working on it. I think I can push the capacity to 300 tons. On the paper this version works already but I will have to test it......
  5. What did you do in KSP today?

    My Saturn V MLV got a huge upgrade! Now it is capable of carrying 250 tons to LEO instead of 200 tons. The upper stage enters into orbit with 17 seconds of fuel remaining. This rocket will be the key element for my upcoming crewed Mars Missions

    Here is the 8K Milkyway Skybox: Here are the ones from @Poodmund https://forum.kerbalspaceprogram.com/index.php?/topic/96851-11-texturereplacer-2413-442016/&page=42#comment-2388097 This is my personal recommendation: https://www.curseforge.com/kerbal/ksp-mods/markus1002s-galaxy-skybox-for-texturereplacer And here are the ones you were talking about: https://forum.kerbalspaceprogram.com/index.php?/topic/96851-11-texturereplacer-2413-442016/&page=66&tab=comments#comment-2933813
  7. What did you do in KSP today?

    Very first Ariane 5 ECA mission ! Lift- off! I only had problems with the upper stage TWR (0.18 for this mission and 12m30sec burn), so I transferred the fuel down to the corestage.
  8. What did you do in KSP today?

    Today the Callisto Lander entered into its orbit around Callisto. Although I managed to hit Callisto with a relative inclination of -0.1 degrees and at my apoapsis , I was not able to land. Fine tuning my approach I wanted to use all of my fuel, so I had to time the stage separation very precisely At this moment I realized that I dont have enough fuel for a landing Capture ! Low Callisto orbit, 64km x 70km Well at least I can farm the science from every biome and a newer version of this vessel is on its way to Jupiter
  9. What did you do in KSP today?

    My Mars Return Vessel (MRV) arrived at Mars and performed an aerobreak maneuver. Lowest altitude: 30km Heatshield separation and rising the periapsis to 290km. This will (hopefully) return back to Earth in T-540 days.
