Captain of the Starship Exeter who violated the Prime Directive at planet Omega IV in 2268. On Omega IV, Tracey believed he had found the secret to virtual immortality, but instead only found the long-lived survivors of a terrible bacteriological war. Returning to his ship, Tracey brought back a deadly virus that killed all of his crew. Tracey then became involved with an ancient struggle between the Yangs and Kohms on Omega IV, providing phaser weapons to that primitive civilization. Tracey was later taken into custody by Starship Enterprise personnel and charged with violating the Prime Directive at Omega IV. (“The Omega Glory” [TOS]). Morgan Woodward also played Dr. Simon Van Gelder in “Dagger of the Mind” (TOS).
~1:[3,#B],6:[2,#I],21:[2,#B],32:[1,#B]@1Tracy, Lieutenant Karen@2(Virginia Aldridge). Starship Enterprise technician who was to run a psychotricorder analysis on Montgomery Scott on planet Argelius II in 2267. She was killed by the alien entity, Redjac, just prior to the analysis. (“Wolf in the Fold” [TOS]).
~1:[1,#BI],3:[1,#BI],4:[2,#B],14:[2,#B],19:[1,#I],22:[1,#I],28:[2,#BI],40:[1,#I],55:[1,#B]@1Trager@2Cardassian Galor -class warship, with a crew of six hundred, commanded by Gul Macet. In 2367, the Trager attacked the Enterprise -D in retaliation for the U.S.S. Phoenix's attack on a Cardassian science station. The action by the Phoenix had been a violation of the 2366 peace treaty between the Federation and the Cardassians. (“The Wounded” [TNG]).
~1:[1,#B],8:[1,#B],25:[1,#B],38:[1,#B],74:[1,#B]@1Tralesta@2One of several clans of the Acamarian people. The Tralestas were all but wiped out in a massacre by their blood enemies, the Lorank clan, in 2286. One of the five surviving Tralestas, a woman named Yuta, underwent a biological alteration to slow her aging process so that she could exact revenge on the Lornaks. Over the next century, Yuta systematically tracked down and killed all the Lornaks with a genetically engineered microvirus. (“The Vengeance Factor” [TNG]).
~1:[2,#B],22:[1,#BI]@1Tranome Sar@2Site of a battle between the Klingons and the Romulans. The father of an officer aboard the Klingon vessel Pagh was captured in this conflict, but was not allowed to die. He later escaped and returned to the Klingon Homeworld, to await death in disgrace. (“A Matter of Honor” [TNG]).
~1:[1,#B],10:[1,#B],12:[1,#B],60:[2,#I]@1transmuter@2 A thought-conversion device used by the extragalactic life-forms Korob and Sylvia. The transmuter resembled a small wand, and served as a director or amplifier, converting their thoughts into actual matter or powerfully convincing images. Using the transmuter, Korob and Sylvia were able to create illusional humanoid forms for themselves, and were able to capture crew members from the Starship Enterprise. The transmuter was destroyed by Captain Kirk in order to permit he and his crew to escape, whereupon Korob and Sylvia died. (“Catspaw” [TOS])
~1:[2,#B],24:[1,#B],28:[1,#B],45:[6,#I]@1transparent aluminum@2Optically clear, structurally rigid material used for construction in the 23rd century. Transparent aluminum was first devised in 1986 by Dr. Nichols, a scientist at Plexicorp in San Francisco. Nichols apparently had some assistance from time-traveling Starfleet personnel in making the invention. (Star Trek IV: The Voyage Home).
~
~1:[2,#B],29:[1,#I],50:[2,#BI]@1transport, near-warp@2Term used to describe use of the transporter at relativistic speeds (near to the speed of light). A somewhat disconcerting experience to those being transported. The Enterprise -D used this technique to transport an away team to Gravesworld while en route to an emergency rendezvous with the U.S.S. Constantinople. (“The Schizoid Man” [TNG]).
~1:[3,#B]@1transporter carrier wave@2A subspace signal through which a transporter beam is propagated. Romulan transporters, with minor adjustments, can be made to simulate the carrier wave of a Starfleet transporter. (“Data's Day” [TNG]).
~1: [3, #b], 23: [1, #b], 32: [2, #bi], 35: [1, #b]@1Transporter Code 14@2Command for an object to be dematerialized, then immediately rematerialized in a dissociated condition, effectively destroying the object. Captain Picard used Transporter Code 14 to destroy the fabled Tox Uthat at Risa in 2366. (“Captain's Holiday” [TNG]).
~1:[3,#B],52:[2,#B]@1transporter ID trace@2A computer record maintained by a Federation starship's transporter system, recording the identity of all transport subjects. The transporter ID trace provided a useful means of verifying whether or not a person has actually been beamed. (“Unnatural Selection” [TNG], “Remember Me” [TNG]). Data and Dr. Beverly Crusher compared Ambassador T'Pel's transporter ID trace to her “remains,” left on the transporter pad after her apparent death in 2367. The single bit errors discovered by this comparison proved the remains were not those of the ambassador. (“Data's Day” [TNG]).
~1:[2,#B],85:[2,#B],88:[2,#B]@1transporter psychosis@2Rare medical disorder caused by a breakdown of neurochemical molecules during transport. Transporter psychosis was first diagnosed in 2209 by researchers on planet Delinia II. The condition affected the body's motor functions, as well as autonomic systems and higher brain functions. Victims were found to suffer from paranoid delusions, multi-infarct dementia, tactile and visual hallucinations, and psychogenic hysteria. Peripheral symptions included sleeplessness, accelerated heart rate, myopia, muscular spasms, and dehydration. The problem was eliminated around 2319 with the development of the multiplex pattern buffer. Lieutenant Reginald Barclay, suffering from acute fear of transporting, believed he might have been experiencing transporter psychosis. (“Realm of Fear” [TNG]).
~1:[3,#B],7:[1,#B],43:[24,#I],72:[3,#I],77:[1,#I]@1transporter test article@2A cylinder of duranium about one meter tall and 25 centimeters in diameter. Used to test transporter performance by beaming the article away and then back to a transporter pad, or simply beaming it between pads. (“Hollow Pursuits” [TNG]). The transporter test article prop was made from a Navy sonobuoy casing. The same shape was used for quite a number of props in Star Trek: The Next Generation and in the Star Trek movies.
~1:[2,#B],9:[2,#B]@1Transporter Theory@2A class taught at Starfleet Academy. Reginald Barclay studied this subject under Dr. Olafson. (“Realm of Fear” [TNG]).
~
~
~1:[2,#B],42:[1,#I],52:[1,#B]@1transwarp conduit@2Artificially created subspace tunnel. Inside the conduit, the normal limitations of subspace travel did not apply. Ships that were able to access the transwarp state could travel at speeds at least twenty times greater than the maximum warp of Galaxy -class starships. In 2369, a previously unknown type of Borg ship was traversing Federation space using a series of transwarp conduits, which they accessed by transmitting an encoded high-energy tachyon pulse. (“Descent, Part I” [TNG]).
~1:[2,#B],35:[1,#I],36:[1,#BI],37:[7,#I]@1transwarp drive@2Experimental technology for increasing the efficiency and speed of starship propulsion systems. Although initially showing great promise, the transwarp development project eventually proved unsuccessful and was abandoned after extensive testing on the Starship Excelsior. (Star Trek III: The Search for Spock).
~
~1:[2,#B],21:[1,#I],28:[1,#I],48:[5,#I],56:[3,#I],60:[3,#I]@1travel pod@2Small shuttle vehicle used for inspection tours at Starfleet's orbital drydock facilities. Kirk and Scott rode to the Enterprise in a travel pod when the Enterprise's transporters were not functional during the final preparations for the ship's departure to intercept the V'Ger entity in 2271. (Star Trek: The Motion Picture, also seen in Star Trek II and Star Trek IV).
~1: [1, #b], 93: [1, #i], 123: [2, #b], 150: [1, #i]@1Traveler@2(Eric Menyuk). Humanoid from the distant planet Tau Alpha C. The Traveler possessed the ability to manipulate a previously unsuspected relationship between space, time, and thought, serving as a “lens,” focusing the energies of thought in himself and others. Those energies could be translated into reality, although 24th-century science has yet to grasp these principles. He was a student of humanoid behavior, and sought passage on Federation ships as a means of observing humans, posing as an assistant to Starfleet propulsion specialist Kosinski. When the Traveler and Kosinski were aboard the Enterprise -D, a slight miscalculation caused the Traveler to send the ship first to Galaxy M-33, then to an even greater extragalactic distance. During that time, the Traveler befriended young Wesley Crusher and encouraged Picard to support Crusher's unusual talents in mathematics, engineering, and science. (“Where No One Has Gone Before” [TNG]). The Traveler returned to the Enterprise -D in 2367 when a static warp bubble, accidentally created by Wesley Crusher from Kosinski's equations, trapped Dr. Beverly Crusher in an alternate reality. The Traveler helped Wesley use his mental abilities to establish the stable gateway through which Beverly was able to return, just prior to the collapse of the warp bubble. (“Remember Me” [TNG]).
~1:[2,#B],9:[2,#B],19:[1,#B],34:[1,#I]@1Travers, Commodore@2Commander of Federation outpost on planet Cestus III in 2267 before it was destroyed by the Gorns. Travers was known for his hospitality, so Kirk and his senior officers from the Enterprise eagerly accepted an apparent invitation from Travers for dinner at the outpost before learning that nearly everyone on Cestus III had been killed in the Gorn attack. (“Arena” [TOS]).
~1:[3,#B],10:[3,#B],26:[3,#B],60:[2,#B],67:[1,#I]@1Treaty of Algeron@2 Peace accord between Earth and the Romulan Star Empire that concluded the Romulan Wars around 2160. The Treaty of Algeron established the Romulan Neutral Zone, violation of which by either side without adequate notification would be considered an act of war. (“The Defector” [TNG]). The Treaty of Algeron also forbids the Federation from developing or using cloaking device technology in its spacecraft. (“The Pegasus” [TNG]).
~1:[3,#B],7:[4,#B],13:[2,#B],46:[11,#I],57:[1,#BI],58:[5,#I],63:[2,#BI],65:[22,#I]@1Treaty of Alliance@2Agreement between the United Federation of Planets and the Klingon Empire ending the war between the two powers. The pact allows for mutual aid and defense against aggressors, but forbids interference in the internal affairs of either government. (“Redemption, Part I” [TNG]). It is not clear if this treaty was established during the Khitomer conference of 2293, after the Narendra III incident of 2344, after the Khitomer rescue in 2346, or at some other point not yet established in an episode or film.
~1:[1,#B],8:[3,#B],13:[1,#B],24:[1,#B]@1Trefayne@2(David Hillary Hughes). Member of the Council of Elders on planet Organia who telepathically voiced happenings outside the council chambers on planet Organia in 2267. (“Errand of Mercy” [TOS]).
~1:[1,#B],11:[1,#I],33:[2,#B],52:[1,#B],76:[1,#I],106:[68,#I]@1Trelane@2(William Campbell). Life-form of unknown origin who kidnapped several Enterprise crew members in 2267. A tall, dashing humanoid male in appearance, Trelane was actually a small child from a race of noncorporal life-forms possessing enormous powers. With his ability to change matter to energy at will, he created the planet Gothos and manufactured an elaborate façade of a Gothic castle from Earth. Trelane patterned himself after an 18th-century Earth squire. He toyed with the Enterprise personnel, eventually forcing his parents to keep him from making any more planets until he could learn not to be cruel to inferior life-forms. (“The Squire of Gothos” [TOS]). Actor William Campbell also played Koloth in “The Trouble with Tribbles” (TOS). The voice of Trelane's mother was provided by Barbara Babcock, who also played Mea 3 in “A Taste of Armageddon” (TOS), the voice of Isis, the cat, in “Assignment: Earth” (TOS), the voice of Commander Loskene in “The Tholian Web” (TOS), and Philiana in “Plato's Stepchildren” (TOS). James Doohan (Scotty) provided the voice of Trelane's father.
~1:[1,#B],9:[2,#B],17:[1,#B],44:[14,#I]@1Trent@2(Leonard J. Crowfoot). A citizen on planet Angel One who worked as an assistant to Beata, leader of the planet's governing council. Like most males on the planet, Trent was submissive to the authority of the ruling female class. (“Angel One” [TNG]). Leonard Crowfoot also played the preliminary android version of Lal in “The Offspring” (TNG).
~1:[2,#B],10:[1,#B],12:[2,#B],55:[2,#I]@1tri-cobalt satellite@2Energy weapon in the war between planets Vendikar and Eminiar VII that ended in 2267. None of these devices were used for some 500 years, but simulations of them were used in the computer war between the two planets. A tri-cobalt satellite was used for the mathematical attack during which the original Starship Enterprise was declared a casualty in 2267. (“A Taste of Armageddon” [TOS]).
~1:[1,#B],26:[1,#B],33:[3,#B],52:[2,#B]@1tri-magnesite@2Chemical that, combined with trevium, can produce an intensely bright light rivaling that of a star. Tri-magnesite satellites were considered for use at planet Deneva in 2267 for eradication of the Denevan neural parasites, but a more limited spectrum of light was found to be preferable. (“Operation— Annihilate!” [TOS]). SEE: ultraviolet satellite.
~1:[2,#B],26:[1,#B],49:[9,#I]@1tri-ox compound@2Medication used to help a patient breathe more easily in a thin or oxygen-deprived atmosphere. When Kirk faced hand-to-hand combat with Spock on Vulcan in 2267, McCoy said he would administer tri-ox to Kirk to help him compensate for the thin Vulcan atmosphere. (“Amok Time” [TOS]). McCoy also administered tri-ox in “The Tholian Web” (TOS).
~1:[1,#B],7:[2,#B],46:[2,#B],87:[1,#B]@1Triacus@2Class-M planet surveyed by the Starnes Expedition in 2268. The explorers unearthed an evil entity that drove the adult members of the colony to commit mass suicide. According to legend, Triacus was the home to a band of marauders who attacked the inhabitants of Epsilon Indi. After many centuries, the marauders were destroyed by those they had attempted to conquer. The legend also warned the essence of those destroyed would live again to do evil throughout the galaxy. (“And the Children Shall Lead” [TOS]). SEE: Gorgan.
~1:[2,#B],29:[1,#B],34:[1,#I]@1triangular envelopment@2A classic attack posture in which three spacecraft surround an enemy vessel at points describing the vertices of an equilateral triangle. Triangular envelopment was used by Talarian forces when threatening the Enterprise -D in 2367. (“Suddenly Human” [TNG]).
~1:[1,#B],13:[2,#B],43:[4,#B],54:[1,#I],91:[1,#B],130:[1,#I],150:[11,#I]@1tribble@2Soft, furry warm-blooded animal sold as a pet by interstellar trader Cyrano Jones. Tribbles are bisexual and capable of reproducing at prodigious rates, although they will stop breeding when food is withdrawn. Cyrano Jones gave a tribble to Lieutenant Uhura at Deep Space Station K-7 in 2267. When Uhura returned to the Enterprise with her new pet, the tribble quickly multiplied to the point where its offspring nearly overran the ship. Tribbles also multiplied on Station K-7, somehow finding their way into storage compartments containing a valuable grain called quadrotriticale. The grain had been poisoned by a Klingon spy, a fact revealed when many of the tribbles were found dead. The remaining tribbles on K-7 were presumably removed by Cyrano Jones, while Scotty beamed the tribbles from the Enterprise to the Klingon ship, where he expected them to be “no tribble at all.” (“The Trouble with Tribbles” [TOS]). Tribbles were also seen in the bar visited by McCoy in Star Trek III.
~1:[1,#B],11:[1,#BI],14:[1,#B]@1triceron@2An explosive compound. The bomb used to disrupt the Sonchi ceremony aboard K'mpec's ship was of a triceron derivative. (“Reunion” [TNG]).
~1:[1,#B],9:[1,#B],12:[2,#B],38:[2,#B]@1triclenidil@2One of several chemicals used by the Angosians during the Tarsian War to “improve” their soldiers, making them more effective in combat. Unfortunately, the effects of many of these drugs were irreversible. (“The Hunted” [TNG]). SEE: Danar, Roga.
~1:[1,#B]@1tricorder@2Multipurpose scientific and technical instrument. This handheld device incorporates sensors, computers, and recorders in a convenient, portable form. (“The Naked Time” [TOS]). Several models of tricorders have been used by starship crews over the years. All of them have featured state-of-the-art sensing technology, and all have been an essential part of starship missions and operations. Specialized tricorders are available for specific engineering, scientific, and medical applications. Standard-issue Starfleet tricorders were unable to detect subspace phenomena in 2366. (“The Bonding” [TNG]). They were also incapable of sensing neutrino emissions. (“The Enemy” [TNG]).

~1:[1,#B],38:[2,#B],44:[4,#I],48:[1,#BI],49:[18,#I]@1tricordrazine@2A powerful neurostimulant drug usually administered subcutaneously by hypospray. Tricordrazine treatment was successfully used by Dr. Pulaski to stimulate neural activity in William Riker when he had suffered neural injury on an away mission at planet Surata IV. (“Shades of Gray” [TNG]). Tricordrazine was based on cordrazine, the drug that sent McCoy on a paranoid flight in “The City on the Edge of Forever” (TOS).
~1:[1,#B],11:[3,#B],42:[1,#B],44:[2,#B]@1tricyanate@2A purple crystalline substance that occurs naturally on planet Beta Agni II. Toxic to humanoids, tricyanate contamination was found in the water supply of the Beta Agni II colony in 2366, an incident later found to have been engineered by Zibalian trader Kivas Fajo. (“The Most Toys” [TNG]).
~1:[2,#BI],4:[1,#I],13:[1,#I],27:[1,#I],33:[1,#B],37:[1,#I],52:[1,#I],59:[1,#I],68:[1,#I],78:[1,#I],80:[23,#I]@1Trieste, U.S.S.@2A Merced -class Federation starship, Starfleet registry number NCC-37124. The Trieste was stationed near Starbase 74 and was unable to render assistance when the Enterprise -D was hijacked by the Bynars in 2364. The Trieste was some 66 hours away at the time. (“11001001” [TNG]). Data served aboard the Trieste prior to his assignment to the Enterprise -D. During Data's tour of duty on the Trieste, the ship once fell through a wormhole. (“Clues” [TNG]). The Trieste was named for the bathyscaphe in which oceanographer Jacques Piccard (for whom Captain Picard was named) explored Earth's Marianas Trench in the 1960s.
~1:[2,#B],18:[3,#B]@1trilaser connector@2Medical instrument used by Dr. McCoy to restore Spock's brain to his body on planet Sigma Draconis VI in 2268. (“Spock's Brain” [TOS]).

The Tripoli was the ship that discovered the android Data at the remains of the Federation colony at Omicron Theta in 2338. The crew of the Tripoli activated Data, who later went on to become a member of Starfleet. (“Datalore” [TNG]). The Tripoli was decommissioned and was relegated to the Zed-15 surplus depot at planet Qualor II. In 2368, the Tripoli was stolen by Romulan operatives. (“Unification, Part I” [TNG]).
~1:[2,#B]@1tripolymer composites@2Material used in the construction of the android Data, who has about 24.6 kilograms of the material in his body. (“The Most Toys” [TNG]). Tripolymers are not electrically conductive. (“Disaster” [TNG]).

~1:[1,#B],20:[1,#B],43:[2,#B]@1Triskelion@2Planet in the M24 Alpha, a trinary star system. The planet was ruled by three disembodied brains called Providers, who maintained a colony of humanoid slaves for gaming purposes. These slaves were freed in 2268. (“The Gamesters of Triskelion” [TOS]). SEE: drill thralls.
~1:[1,#B],25:[2,#B]@1tritium@2Isotope of hydrogen with an atomic weight of 3. Low concentrations of tritium gas were used to trace particle flow to a dangerous graviton field buildup on station Deep Space 9 in 2369. Tritium gas is mildly radioactive and is hazardous when highly concentrated, but the amount used on the station was very small. (“Q-Less” [DS9]).

~1:[1,#B],6:[1,#B],44:[1,#B],57:[1,#B],60:[1,#B]@1Troglytes@2Citizens of the planet Ardana who lived on the planet's surface, performing mining and other labor-intensive tasks that supported the privileged few who lived in the cloud city of Stratos. The Troglytes who worked in the mines were forced to breathe toxic zenite gas, resulting in impairment of mental processes. Troglyte political activists, known as Disrupters, forced the Stratos government in 2269 to recognize these hazardous working conditions and provide appropriate safety equipment. The Troglytes expressed an intent to win political and economic equality, as well. (“The Cloud Minders” [TOS])
~1:[2,#B],8:[2,#I],24:[2,#B],27:[3,#B],34:[2,#B],62:[1,#B],106:[2,#BI],108:[1,#B],137:[3,#B],166:[2,#BI],198:[2,#B],204:[3,#B],233:[2,#B],268:[1,#I],282:[2,#B],320:[48,#I]@1Troi, Deanna@2(Marina Sirtis). Counselor aboard the U.S.S. Enterprise -D under the command of Captain Jean-Luc Picard. (“Encounter at Farpoint” [TNG]).
Daughter of Lwaxana Troi and Ian Andrew Troi, Deanna was betrothed to Wyatt Miller through the Betazoid custom of genetic bonding when they were both children. Deanna and Wyatt never married, though, because Wyatt chose to join the last surviving Tarellians in search of a cure for the Tarellian plague. (“Haven” [TNG]).
Deanna's father used to read her heroic stories about the ancient American West on planet Earth, and she remained fond of these stories into her adulthood. (“A Fistful of Datas” [TNG]). SEE: Ancient West; Durango. Troi studied psychology at the University of Betazed prior to her joining Starfleet. (“Tin Man” [TNG]).
While a psychology student on Betazed, Troi became romantically involved with Lieutenant William T. Riker. (“MŽnage ˆ Troi” [TNG]). Troi had hopes of a serious commitment between the two, but Riker's career plans took him away to an assignment aboard the U.S.S. Potemkin. (“Encounter at Farpoint” [TNG], “Second Chances” [TNG]). Troi graduated from the Academy (possibly having taken classes on Betazed) in 2359. (“Conundrum” [TNG]). Troi was once involuntarily impregnated by an unknown noncorporeal life-form. Troi named the child Ian Andrew Troi, after her late father. (“The Child” [TNG]).
Troi suffered a brief loss of her empathic powers in 2367 from proximity to a newly discovered group of two-dimensional creatures. Although Troi found the loss disconcerting, she was pleased to discover that she could still function as ship's counselor without her Betazoid abilities. (“The Loss” [TNG]). Counselor Troi assumed temporary command of the Enterprise -D on stardate 45156 when the ship was disabled from collision with two quantum filaments. Troi, who held the rank of lieutenant commander, was the senior officer on the bridge at the time. (“Disaster” [TNG]). Troi said she never met a chocolate she didn't like. (“The Price” [TNG], “The Game” [TNG]). Deanna Troi was first seen in “Encounter at Farpoint” (TNG). Marina Sirtis originally auditioned for the part of Natasha Yar and was almost cast for the part, but Gene Roddenberry decided at the last moment to switch the roles of Yar and Troi between Sirtis and Denise Crosby.
