Editing Unity (ISS module) (section)

== Launch and initial berthing ==
''Unity'' (with its two attached PMAs) was carried into orbit as the primary cargo of the [[Space Shuttle Endeavour|Space Shuttle ''Endeavour'']] (OV 105) on [[STS-88]], the first [[Space Shuttle]] mission dedicated to assembly of the station. On 6 December 1998, the STS-88 crew mated the docking port of the PMA on the aft berthing port of ''Unity'' with the forward hatch of the already orbiting ''[[Zarya (ISS module)|Zarya]]'' module. (''Zarya'' was a mixed Russian-U.S. funded and Russian-built component launched a few days before aboard a [[Russia]]n [[Proton (rocket family)|Proton]] [[launch vehicle]] from [[Baikonur Cosmodrome|Baikonur]], [[Kazakhstan]].)
