Although Human, Dr. Jones had never visited the planet Earth; she did however spend four years on Vulcan. While on Vulcan, she studied Vulcan mental discipline to turn her telepathic abilities "off" in order to maintain her sanity. In 2268, she was given an assignment to coordinate with the Medusan Ambassador Kollos after the initial offer to Commander Spock was turned down. Her assignment's success was based upon her ability to achieve a true mind-link. Miranda Jones was played by Trek veteran Diana Muldaur.
