Penyandaran dan penambatan wahana antariksa
Mekanisme penyandaran dan penambatan wahana antariksa (bahasa Inggris: docking and berthing) adalah mekanisme yang digunakan untuk menghubungkan satu wahana antariksa ke wahana antariksa lainnya (termasuk stasiun luar angkasa). Sambungan dapat bersifat sementara atau semipermanen untuk modul stasiun luar angkasa.
Mekanisme penyandaran (docking) secara rinci merujuk pada penggabungan dua buah wahana antariksa yang terbang bebas.[1][2][3][4] Sementara itu, mekanisme penambatan (berthing) merujuk pada penghubungan wahana/modul tidak aktif pada antarmuka penghubung wahana antariksa lainnya menggunakan lengan robot—bukan menggunakan propulsi dari wahana tidak aktif.[1][3][4] Karena proses pelepasan tambat modern memerlukan banyak tenaga dan memakan waktu yang lama, mekanisme penambatan tidak cocok untuk evakuasi cepat awak wahana antariksa dalam kondisi darurat.[5]

Docking is when one incoming spacecraft rendezvous with another spacecraft and flies a controlled collision trajectory in such a manner so as to align and mesh the interface mechanisms. The spacecraft docking mechanisms typically enter what is called soft capture, followed by a load attenuation phase, and then the hard docked position which establishes an air-tight structural connection between spacecraft. Berthing, by contrast, is when an incoming spacecraft is grappled by a robotic arm and its interface mechanism is placed in close proximity of the stationary interface mechanism. Then typically there is a capture process, coarse alignment and fine alignment and then structural attachment.

Berthing refers to mating operations where an inactive module/vehicle is placed into the mating interface using a Remote Manipulator System-RMS. Docking refers to mating operations where an active vehicle flies into the mating interface under its own power.
