A Starfleet repair and construction facility in Earth orbit, where the Enterprise-D was refitted after its battle with the Borg in 2367.
Earth Station McKinley is an orbital shipyard above Earth. Its most recognisable feature is a set of large articulated arms that close around a starship while work is carried out.
It is seen in the Next Generation episode Family, set in 2367. After the Borg incursion of The Best of Both Worlds, the USS Enterprise-D spends several weeks docked there for repairs and a refit, and the crew takes leave on Earth. Picard visits his brother in La Barre, Worf's adoptive parents come aboard, and Wesley Crusher views a message from his late father.
The station is mentioned again in later stories as a place where ships are serviced, and its design was reused for other Starfleet docks. It is one of several orbital yards serving Earth, alongside Spacedock and the San Francisco Fleet Yards.
