## Soyuz-MS. Godot 4.7. Units: 1 m.
|
||||
## Axes: dock / forward +Z, dorsal +Y, starboard +X. The service engine exhausts -Z.
|
||||
## rcs_direction uses those axes. Nose thrust is +Z, not +Y.
|
||||
## Drive is a chemical torch (short, warm). Abort motors are the same ribbons as Kestrel.
|
||||
## See PARTICLE_FX.md.
