Triple

Target class: space station docking interface
Context triple: [Russian Service Module Zvezda aft port, instanceOf, space station docking interface]

• A. spacecraft docking system chosen
  A spacecraft docking system is a coordinated assembly of mechanical interfaces, sensors, and control software that enables two spacecraft to safely approach, align, and connect in orbit for transfer of crew, cargo, or resources.
• B. space station interface standard
  A space station interface standard defines the common physical, electrical, and communication specifications that enable different spacecraft, modules, and systems to reliably connect, dock, and interoperate in orbit.
• C. spacecraft berthing mechanism
  A spacecraft berthing mechanism is a structural and mechanical interface system that enables two spacecraft or modules to be precisely aligned, securely joined, and later separated while maintaining required load paths and connections for power, data, and environmental control.
• D. spacecraft payload adapter
  A spacecraft payload adapter is a structural interface that securely connects a satellite or payload to the launch vehicle, ensuring proper alignment, load transfer, and separation during ascent and deployment.
• E. spacecraft service module
  A spacecraft service module is the section of a spacecraft that houses and provides essential support systems—such as propulsion, power, thermal control, and consumables—to enable and sustain the operation of the crew or payload module.
• F. None of above.
