Acting Ensign Wesley Crusher is assigned regular bridge duty, serving as flight controller (conn). These promotions were not shown, but happened between the end of the first season and the beginning of the second. Captain Picard recruits an old friend, Guinan, to serve as hostess of the Ten Forward lounge. She comes on board the Enterprise -D at Nestoriel III. Guinan was first seen in 'The Child' (TNG). 'Yesterday's Enterprise' (TNG) and 'Redemption Part II' (TNG) established that Guinan had not been aboard the Enterprise -D until sometime after Tasha's death. Data mentions Nestoriel III in 'Time's Arrow Part I' (TNG). |
Stardate 42073.1. Dr. Beverly Crusher accepts a position as head of Starfleet Medical and departs the Enterprise -D. Dr. Katherine Pulaski arrives from the U.S.S. Repulse via shuttlecraft as her replacement. U.S.S. Enterprise -D assigned to transport medical specimens of plasma plague from planet 'audet IX to Science Station Sierra Tango in hope that a cure can be found for an outbreak of the disease on planet Rachelis. The project is supervised by Lieutenant Commander Hester Delt, medical trustee of the Federation Medical Collection Center.Ship's counselor Deanna Troi is impregnated by an unknown alien life form. The resulting child, which gestates and grows at a highly accelerated rate, is the product of this unknown form's desire to learn more about human life. The entity is found to be a source of eichner radiation, compromising the safety of the storage of the deadly plasma plague specimens. Seeking to avoid harm to the Enterprise -D crew, the entity departs the ship. Editors' Note: This episode was originally written for Captain Kirk and his crew for the Star Trek II television series project that was never produced. U.S.S. Enterprise -D heads for Morgana quadrant. After 'The Child' (TNG). |
Stardate 42193.6. The U.S.S. Enterprise -D is updating star charts while en route to the Morgana quadrant. The voyage is interrupted when the Enterprise -D is trapped in a region of space that appears to be devoid of stars or any object other than the Enterprise -D itself. A second ship is eventually sighted, tentatively identified as the Galaxy class U.S.S. Yamato, although further investigation reveals the ship to be a fabrication. The entire situation is eventually determined to be a first-contact scenario with a noncorporeal intelligence known as Nagilum, who is attempting to understand the nature of human life.U.S.S. Enterprise -D continues toward the Morgana quadrant. Just after 'Where Silence Has Lease' (TNG). Geordi La Forge builds a model of the ancient British sailing ship H.M.S. Victory, intended as a gift for Starship Victory captain Zimbata, under whose command La Forge served prior to his Enterprise -D assignment. Prior to 'Elementary, Dear Data' (TNG). Editors' Note: In reality, Geordi's beautiful H.M.S. Victory model still graces the late Gene Roddenberry's office in his home. |
Stardate 42286.3. U.S.S. Enterprise -D arrives three days early for scheduled rendezvous with the Victory. While awaiting the Victory's arrival, user error on the part of a holodeck participant results in the accidental creation of a computer software-based sentient intelligence within a simulation program. This intelligence is based on the character of Dr. James Moriarty from the Sherlock Holmes stories. To avoid the destruction of what is apparently a self-aware life-form, Captain Picard orders the Moriarty simulation program saved until a way can be found to give physical form to the synthetic intelligence.U.S.S. Victory arrives for rendezvous with the Enterprise -D. Captain Zimbata receives his gift of Geordi's model. Just after 'Elementary, Dear Data' (TNG). |
Stardate 42402.7. U.S.S. Enterprise -D, traveling through the Omega Sagitta system, offers assistance to space vehicle Erstwhile, an interplanetary vessel in need of guidance system repairs.While in the Omega Sagitta system, Captain Picard mediates a dispute between planets Atlec and Straleb. Ruling families of both planets have filed claims against Erstwhile captain Thadiun Okona. The dispute is resolved when Benzan, son of Secretary Kushell (of the Legation of Unity of the planet Straleb) and Yanar, daughter of Debin (captain of a Straleb space vessel) agree to marry. U.S.S. Enterprise -D responds to a distress from Kareen Brianon, assistant to noted molecular cyberneticist Dr. Ira Graves on the planet Gravesworld.

An away team is left on Gravesworld, while the Enterprise -D proceeds expeditiously to a successful rescue mission to the Constantinople. Still on Gravesworld, Dr. Ira Graves is discovered by Enterprise -D staff physician Dr. Selar to be terminally ill. Before his death Graves succeeds in recording the sum of his personal knowledge into the Enterprise -D computer system.Editors' Note: Although this has been the only appearance of the Vulcan Dr. Selar to date, we did hear Selar being paged over the PA system of the alternate timeline Enterprise -D in 'Yesterday's Enterprise' (TNG), and Selar was also mentioned by Dr. Crusher in 'Remember Me' (TNG). |
Stardate 42477.2. U.S.S. Enterprise -D is unexpectedly diverted to the Ramatis star system, assigned to transport famed mediator Riva to help resolve a bitter planetary conflict on planet Solais V. Initial attempts to negotiate a cease-fire between the two combatants are unsuccessful, but Riva remains behind to continue efforts to bring the adversaries together in a quest for peace.The first officer of the Starship Lantree is treated for Thelusian flu, an exotic but harmless rhinovirus. Five days prior to 'Unnatural Selection' (TNG). U.S.S. Lantree under the command of Captain Iso Telaka visits the Darwin genetic research station on planet Gagarin IV. It is not realized at the time that exposure to the genetically engineered children of Darwin station scientists results in hyperaccelerated aging of all Lantree personnel. Three days prior to 'Unnatural Selection' (TNG), according to Telaka's log. Twenty Lantree personnel are killed by unknown causes, leaving only six crew members alive. Captain Telaka orders course set for nearest Federation outpost. Just prior to 'Unnatural Selection' (TNG), stardate 42293.1. |
Stardate 42494.8. U.S.S. Enterprise -D mission to Star Station India is interrupted by a distress call from the U.S.S. Lantree. Responding to the call, Enterprise -D discovers all Lantree personnel to be dead from an unknown malady strongly resembling old age.The source of this affliction is learned to be the Darwin genetic research station on planet Gagarin IV. Further investigation determines the aging disease to be caused by genetically engineered children at the station. These children are found to possess an unusually powerful immune system that actually attacks potential causes for infection, including other human beings. Remains of Starship Lantree are destroyed to eliminate risk of further contamination. U.S.S. Enterprise -D resumes mission to rendezvous with Starfleet courier at Star Station India. Just after 'Unnatural Selection'. (TNG). |
Stardate 42506.5. U.S.S. Enterprise -D at Starbase 179 to participate in new officer exchange program. Serving temporarily aboard the Enterprise -D is Ensign Mendon, a Starfleet officer from the planet Benzar. Enterprise -D executive officer William Riker is assigned duty aboard the Klingon vessel Pagh, the first Federation Starfleet officer to serve aboard a Klingon ship.A previously unknown submicron life-form is discovered by Mendon, who reports the life-form has been detected on the hulls of the Enterprise -D and the Pagh. Mendon devises a successful means of removing the parasites from both ships, using a tunneling neutrino beam. |
Stardate 42523.7. U.S.S. Enterprise -D at newly established Starbase 173 for crew rotation and offloading experiment modules. Lieutenant Commander Data is assigned to Commander Bruce Maddox for study of Data's positronic neural systems to further the goal of manufacturing additional androids for Starfleet service. Data declines to accept the transfer, and Starfleet Judge Advocate General Phillipa Louvois subsequently rules that Data is indeed a life-form with full civil rights, and that he is therefore free to make his own decisions.Editors' Note: This episode shows for the first time the weekly poker game that became a fixture of off-duty life for our heroes. |
Stardate 42568.8. U.S.S. Enterprise -D assigned diplomatic mission to ferry Salia, a young planetary head of state, from planet Klavdia III to her home on Daled IV. Salia, an allasomorph, is returned to her home to accept her role of leader, and will attempt to unite the warring factions of her planet.U.S.S. Yamato at planet Denius III, where Captain Donald Varley, participating in an archaeological study, deciphers evidence from an ancient Iconian artifact, making it possible to determine the actual location of the Iconian homeworld, somewhere in the Romulan Neutral Zone. Varley, citing the potentially disastrous consequences should the Romulans gain access to Iconian weapons technology, orders the Yamato to proceed to Iconia. Near Iconia, the Yamato is scanned by an Iconian space probe. Shortly prior to 'Contagion' (TNG), according to Varley's log. |
Stardate 42609.1. The Enterprise -D responds to distress call from Starship Yamato in the Romulan Neutral Zone, but is unable to save the ship or its crew from destruction due to major on-board computer malfunction. Investigation determines the Yamato to have been the victim of a computer software weapon surviving from the long-dead planet Iconia. This weapon is believed to have been transmitted during a sensor scan from an Iconian probe. During the investigation, the Romulan warbird Haakona is similarly infected by the software weapon, but assistance from the Enterprise -D averts destruction of the Romulan craft as well as an interstellar incident.A passing Klingon cruiser reports discovering pieces of an unknown space vehicle in the upper atmosphere of the eighth planet in the Theta 116 system. Enterprise -D diverts from scheduled course to investigate. Just prior to 'The Royale' (TNG). |
Stardate 42625.4. U.S.S. Enterprise -D investigates report of wreckage in orbit of the eighth planet in the previously unmapped Theta 116 system. An elaborate recreation of a 20th-century Earth environment is discovered on the otherwise uninhabitable planetary surface. Investigation determines the environment to have been created by an unknown alien intelligence in an effort to create a habitat for Colonel Steven Richey, the commander of the space vehicle Charybdis. That vehicle had been reported missing in 2037 after the third unsuccessful attempt to explore beyond Earth's solar system.U.S.S. Enterprise -D makes layover stop at Starbase 73. Just prior to 'Time Squared' (TNG). |
Stardate 42679.2. Mission to planet Endicor is interrupted by discovery of a duplicate of Enterprise -D shuttlepod 5, drifting in space. Discovered on board the recovered vehicle is a duplicate of Captain Jean-Luc Picard. Both the shuttle and the duplicate captain had apparently come backward in time six hours, during which the Enterprise -D had evidently been lost with all hands except the captain. The time loop is determined to have been caused by a temporal distortion. This distortion (and the impending destruction of the Enterprise -D) is disrupted when Captain Picard orders the Enterprise -D into the center of the phenomenon.Editors' Note: The shuttlepod seen in this episode, the El-Baz, is named for former NASA planetary geoscientist Farouk El-Baz, currently on faculty at Brown University. Several years ago, El-Baz worked on a documentary film with Star Trek: The Next Generation executive producer Rick Berman. U.S.S. Enterprise -D resumes mission to the Endicor system. Shortly after 'Time Squared'. U.S.S. Enterprise -D at planet Nasreldine. A crew member contracts a flulike illness there. Afterward, minor readout anomalies require an unscheduled course change to Starbase Montgomery for engineering consultations. Prior to 'The Icarus Factor' (TNG). |
Stardate 42686.4. U.S.S. Enterprise -D at Starbase Montgomery for engineering consultations. Starfleet civilian adviser Kyle Riker, father of William Riker, is a guest aboard the Enterprise -D.Commander William Riker is offered command of Starship Aries, a small scout ship serving in frontier areas, but he declines the promotion in favor of continued service aboard the Enterprise -D. This is the second time Riker declines the opportunity to command a starship. U.S.S. Enterprise -D heads for Beta Kupsic. Just after 'The Icarus Factor' (TNG). Lieutenant Commander Data, while performing modifications on ship's sensors, detects a radio transmission from a previously unknown life-form in the Selcundi Drema sector. Data responds to the signal. This action is later determined to be in violation of the Starfleet Prime Directive. 'Pen Pals'. Data told Picard he first detected the signals about eight weeks prior to the completion of the geological survey. That survey was finished six weeks into the episode, suggesting the signals had been received about two weeks prior. |
Stardate 42695.3. U.S.S. Enterprise -D on survey mission of star systems in Selcundi Drema sector. Acting Ensign Wesley Crusher is placed in charge of planetary geophysical surveys.Lieutenant Commander Data reports receipt of a radio signal from a life-form on planet Drema IV. Data also acknowledges responding to the signal, even though such a response was in violation of Prime Directive protection. The signal is determined to be a distress call resulting from massive geologic instability on the planet. Captain Picard determines assistance to be appropriate, even though such intervention is a further violation of the Prime Directive. Picard further orders appropriate steps be taken to minimize cultural contamination from this action. |
Stardate 42761.3. U.S.S. Enterprise encounters the entity Q at the frontier of Federation territory. Q expresses a desire to become a member of Starfleet. When Picard declines the request, Q sends the Enterprise -D some 7,000 light-years across the galaxy. At the previously uncharted star system J-25, evidence is found of a Class-M planet which exhibits massive surface scarring. The phenomenon is similar to that found at outposts Delta Zero Five and Tarod IX near the Romulan Neutral Zone on stardate 41986.At System J-25, the Enterprise -D shortly thereafter makes first contact with a Borg spacecraft. The Borg are determined to be a humanoid species making extensive use of cybernetic implants. Their spacecraft is extremely powerful, but highly decentralized, supporting a hivelike shared consciousness. First contact is a Borg incursion on the Enterprise, resulting in severe damage to the Enterprise -D, the loss of shuttle 06, and the death of eighteen Enterprise -D personnel. Q, apparently satisfied with his demonstration of the hostile and powerful nature of the Borg, later returns the Enterprise -D to Federation space. U.S.S. Enterprise -D travels to Starbase 83. After 'Q Who?' (TNG). |
Stardate 42779.1. Captain Jean-Luc Picard and Ensign Wesley Crusher take personal leave at Starbase 515. Crusher's leave is for the purpose of taking Starfleet Academy exams. Picard reports to the Starbase hospital for routine replacement of his bionic heart.U.S.S. Enterprise -D en route to planet Epsilon IX for astronomical survey of Epsilon Pulsar cluster when diverted to investigate a distress call from the Rhomboid Dronegar sector. The distress call is found to have been sent from a Pakled ship, the Mondor. Further investigation reveals the call was a ruse, an unsuccessful attempt to gain access to Federation weapons technology by capturing Enterprise -D chief engineer Geordi La Forge. U.S.S. Enterprise -D at Starbase 73. Picard has meeting with Admiral Moore to discuss a distress call received from the Ficus sector. Just prior to 'Up the Long Ladder' (TNG). |
Stardate 42823.2. U.S.S. Enterprise -D, having departed from Starbase 73, proceeds to the planet Bringloid V in the Ficus sector. A colony on the planet had sent a distress call because of severe solar flares in that system. At Bringloid V, Enterprise -D personnel evacuate all colonists and discover evidence of a second, previously unknown colony, in a nearby system. Investigating further, the missing colony is discovered on a nearby planet called Mariposa. It is learned that due to a disastrous crash landing of their ship, the Mariposa colony began with only five individuals who used cloning technology in an attempt to keep their society populated. The inhabitants of the colony report, however, that replicative fading threatens to make their culture nonviable. The Bringloidi colonists and the Mariposans agree to a joint settlement in an attempt to make both groups viable. |
Stardate 42859.2. U.S.S. Enterprise -D on diplomatic mission to transport Antedian and Betazoid delegates to a conference on the planet Pacifica to consider the question of admitting planet Antede III to the Federation. The telepathic assistance of Betazed ambassador Lwaxana Troi is instrumental in exposing two Antedian delegates as assassins, intent upon disrupting the conference.A Federation conference on planet Pacifica convenes to consider the petition of planet Antede III for admission to the United Federation of Planets. Just after 'Manhunt' (TNG). Starbase 336 receives an automated transmission from the T'Ong, a Klingon sleeper ship launched in 2290, now returning to Klingon space. 'The Emissary' (TNG). Two days prior to the episode. |
Stardate 42901.3. Special Federation emissary K'Ehleyr is dispatched to the Enterprise -D with orders to intercept the Klingon sleeper ship T'Ong near the Boradis system before its crew is automatically revived. The Enterprise -D mission is based on fears that the T'Ong crew, launched prior to the Khitomer peace conference of 2293, still believes that a state of war exists between the United Federation of Planets and the Klingon Empire. K'Ehleyr's orders include the option to destroy the T'Ong and its crew if necessary, but Captain Picard opposes this course. Instead, he and Lieutenant Worf devise an alternate strategy in which Worf poses as Enterprise -D captain long enough to order the T'Ong's crew to accept command of K'Ehleyr.During the T'Ong crisis, Emissary K'Ehleyr and Enterprise -D security chief Worf renew an old romantic relationship, although K'Ehleyr declines to take the Klingon oath of marriage. Unknown to Worf at the time, their liaison results in the conception of a child. The title of this episode, 'The Emissary' (TNG), should not be confused with 'Emissary, Part I & II' (DS9), which was the 2-hour pilot episode for Star Trek: Deep Space Nine. |
Stardate 42923.4. U.S.S. Enterprise -D participates in strategic simulation exercise near the Braslota star system ordered by Starfleet in preparation for possible conflict with the Borg. Also participating in the exercise is the U.S.S. Hathaway, an older vessel temporarily commanded by William Riker. The entire operation is overseen by Zakdorn tactician Sirna Kolrami. The exercise is briefly interrupted by the Ferengi spacecraft Kreechta, whose commander misinterprets the tactical importance of the obsolete Hathaway.U.S.S. Enterprise -D returns to the nearest starbase. Just after 'Peak Performance' (TNG). |
Stardate 42976.1. U.S.S. Enterprise -D on survey mission to planet Surata IV, when Commander William Riker is injured by accidental contact with indigenous plant form. |
