Editing Unity (ISS module) (section)

== Connecting modules and visiting vehicles ==
''Unity'' has two axial and four radial [[Common Berthing Mechanism]] (CBM) ports. In addition to connecting to the ''Zarya'' module, ''Unity'' connects to the U.S. [[Destiny (ISS module)|''Destiny'' Laboratory Module]] (added on [[STS-98]]), the [[Integrated Truss Structure|Z1 truss]] (an early exterior framework for the station added on [[STS-92]]), the [[Pressurized Mating Adapter|PMA-3]] (also added on [[STS-92]]), and the [[Quest Joint Airlock|''Quest'' Joint Airlock]] (added on [[STS-104]]). During [[STS-120]] the ''[[Harmony (ISS module)|Harmony]]'' module was temporarily berthed to the port-side hatch of ''Unity''. ''[[Tranquility (ISS module)|Tranquility]]'', with its [[Cupola (ISS module)|multi-windowed cupola]], was attached to ''Unity'''s port side during the [[STS-130]] mission, and [[Leonardo (ISS module)|''Leonardo'']] was added to the [[nadir]] hatch during [[STS-133]].

In addition, the ''Leonardo'' and ''Raffaello'' [[Multi-Purpose Logistics Module]]s were each berthed to ''Unity'' on multiple missions.
