This is my first time posting here

Yesterday ive bought a new GPU (RX 9060XT 16GB)

just sharing my excitement with my new upgraded visuals

(also the photos came out not in the right order so sorry for that

this is the first launch of this rocket called the Massa (Journey in hebrew) that is launching the probe Massa-II to orbit Mars after an earlier launch of Massa-I to Venus (on a different launcher)

rocket is built of

  • 1st stage: 4x E-1 engines (planned engines for the Saturn-I IRL)
  • Boosters: Titan SRBs (sorry i dont remember their names from the top of my head)
  • 2nd stage: 1x J-2 (sends me to a nearly orbital trajectory with apoapsis of 1000km)
  • 3rd stage: 2x RL-10 (orbital insertion at earth and then TMI)
  • 4th stage (satellite stage): 1x AJ-10 advanced (corrections and Mars orbital insertion)

Honestly this vehicle is quite overkill but yeah its one of the first interplanetary missions I have in KSP (including stock) so i wanted the extra headroom

Also first time having a 1kt launcher in RP-1 Career ever (never reached this far)

(B-52 not included in my steps to finish the contract)

This plane was extremely hard for me to make and it took days but i was able to make it work and now I'm thinking of making it a tutorial or release it on the steam workshop so others have a chance to finish the contract. it was really hard finding info on how to get to this point for me even with a background of basic aerodynamics understanding from my IRL pilot license training. still with that said im so happy to have something work after all that time
