Are there any androgynous docking/berthing systems currently in use for docking?
I've browsed the list and it seems all the androgynous systems fall into three groups:
- obsolete / used on crafts no longer in use
- used for berthing only
- planned / in development, or craft they are to be used on is in development.
Maybe I missed something, but are currently any androgynous systems used for docking (and not just berthing)? Any spacecraft out there that could dock to other spacecraft?
