The Copernicus was a Federation Galileo-type shuttlecraft that was in service with Starfleet in the late 23rd century, attached to the USS Enterprise-A. It was Shuttle 3.
Copernicus was stored in the shuttlebay during the Enterprise's mission to rescue the Nimbus III hostages and subsequent hijacking by Sybok in 2287. The Copernicus was used by Sybok, Captain James T. Kirk, Spock, and Doctor Leonard McCoy to journey to the surface of Sha Ka Ree due to the Enterprise transporters being inoperable. The shuttle was later destroyed by the malevolent lifeform inhabiting the planet. (Star Trek V: The Final Frontier)
