Hello spacers,
I released version 0.15-1 of sfsim. sfsim is a realistic 3D space flight simulator with an advanced single-stage-to-orbit space craft.
This version displays some orbital information:
height of periapsis above surface
height of apoapsis above surface
time to periapsis
time to apoapsis
This should make it much easier to achieve a stable orbit. For example if the periapsis is moving closer (or even was passed) in the later stages of a launch, you need to pitch up to prevent the spacecraft from dropping.
Also Andrewkn’s Surrealism (Ambient Mix) is played when achieving low Earth orbit (both periapsis and apoapsis above 160 kilometer).
Let me know any feedback and comments in the sfsim playtest discussion forum.
