An Enterprise yeoman who is one of the seven aboard the shuttlecraft Galileo when it is forced down on Taurus II in 2267 under Spock's command.
Yeoman Mears appears in the first-season episode The Galileo Seven. She is assigned to keep the records of a survey of the quasar-like Murasaki 312, travelling with Spock, McCoy, Scott and Lieutenants Boma, Gaetano and Latimer. The shuttle is pulled off course and crash-lands on a planet at the heart of the phenomenon.
While Scott works to get the craft flying, the party is attacked by the giant inhabitants. Latimer and Gaetano are killed, and Mears is shaken about inside the shuttle when the creatures batter its hull.
She is one of the five survivors beamed back to the Enterprise after Spock jettisons and ignites the fuel as a flare. Mears was played by Phyllis Douglas.
