Q 01Who created Star Trek: Deep Space Nine?
Rick Berman and Michael Piller
Rick Berman and Michael Piller developed the show while Gene Roddenberry was dying, making it the first Star Trek series without his direct involvement, though Berman said he had given it his blessing.
Q 02How many episodes of Deep Space Nine were made across its seven seasons?
176
Deep Space Nine ran 176 episodes: season one, which began in January 1993 midway through the broadcast year, had 20, and seasons two through seven had 26 each.
Q 03What is the name of Deep Space Nine's commercial and social hub?
The Promenade
The Promenade is the station's main street, lined with Quark's bar, the infirmary, a temple and Garak's tailor shop; in the early seasons Keiko O'Brien ran a school there for the station's children.
Q 04Who plays Benjamin Sisko on Star Trek: Deep Space Nine?
Avery Brooks
Avery Brooks kept up his professorship in theatre at Rutgers University through all seven seasons, and directed nine episodes of the series himself.
Q 05The station was built by the Cardassians during their occupation of which planet?
Bajor
The Cardassians built the station in orbit of Bajor during their roughly fifty-year occupation of the planet, which ended in 2369 when they withdrew and Bajor's provisional government invited Starfleet in.
Q 06What was the station called under Cardassian rule, before it was renamed Deep Space Nine?
Terok Nor
Terok Nor. The Cardassians built it with Bajoran slave labour to process ore, then wrecked it as they pulled out, which is why Sisko finds a station in ruins in the pilot.
Q 07The wormhole discovered near Deep Space Nine leads to which distant part of the galaxy?
The Gamma Quadrant
The Gamma Quadrant. The wormhole puts the far side of the galaxy within easy reach, turning a backwater outpost into a hub for trade and exploration and, later, the front line of the Dominion War.
Q 08The Bajorans revere Sisko as what?
The Emissary of the Prophets
The Emissary of the Prophets. Sisko is uneasy at first about being a religious figure to the people he was sent to help, and only gradually comes to embrace the role.
Q 09In the pilot, Sisko's wife Jennifer dies aboard the USS Saratoga in which battle against the Borg?
The Battle of Wolf 359
The Battle of Wolf 359. A Borg cube led by the assimilated Picard routs the fleet, which is why Sisko can barely hide his hostility when the two men meet in the premiere.
Q 10Which prototype warship joined Deep Space Nine in season three to allow stories away from the station?
USS Defiant
USS Defiant. Ronald D. Moore, who named the ship, wanted to call it Valiant, but Voyager was about to launch and nobody wanted two Star Trek ships whose names began with V.
Q 11What Starfleet rank does Benjamin Sisko hold when Deep Space Nine begins?
Commander
Commander. Sisko arrives thinking of resigning from Starfleet altogether; by the end of season three he has earned promotion to Captain, in 'The Adversary'.
Q 12Which Next Generation character joined Deep Space Nine's main cast in season four?
Worf
Worf. With ratings falling, the studio told the producers to shake the show up, so the Klingon officer arrived in 'The Way of the Warrior' as his people turned on their allies.
Q 13Odo, the station's security chief, belongs to which shape-shifting species?
Changelings
Changelings. Odo spends two seasons not knowing where he came from, then learns in 'The Search' that his people are the Founders, the hidden rulers of the hostile Dominion.
Q 21Who becomes the first Ferengi to join Starfleet?
Nog
Nog becomes the first Ferengi in Starfleet after Sisko sponsors his Academy application in 'Heart of Stone' (1995); he loses a leg at AR-558 and recovers in 'It's Only a Paper Moon'.
Q 22Which Princess Bride actor plays Grand Nagus Zek, the Ferengi leader?
Wallace Shawn
Wallace Shawn, The Princess Bride's Vizzini, played Zek from 1993; in 'The Dogs of War' the Nagus retires and names as his successor not Quark, who expects it, but his brother Rom.
Q 23Who plays Quark, the Ferengi bar owner?
Armin Shimerman
Armin Shimerman. He had already played one of the first Ferengi on The Next Generation; in the DS9 pilot, Sisko pressures Quark into staying on the station by holding his jailed nephew over him.
Q 14Who plays Odo on Deep Space Nine?
René Auberjonois
René Auberjonois. He acted through a smooth, unfinished-looking mask, explained in the story by Odo never quite getting the humanoid face right.
Q 15The Dominion's genetically engineered shock troops are called what?
The Jem'Hadar
The Jem'Hadar are bred as soldiers and kept obedient by addiction: they depend on the drug ketracel-white, which only the Founders supply.
Q 16In which second-season episode is the Dominion first mentioned?
Rules of Acquisition
'Rules of Acquisition' (1993) first names the Dominion: while Quark negotiates a tulaberry-wine deal with the Dosi, they reveal that the Karemma belong to it. Its soldiers do not appear until the season-two finale.
Q 17Which actor played two recurring Deep Space Nine roles, the Ferengi Brunt and the Vorta Weyoun?
Jeffrey Combs
Jeffrey Combs. Weyoun dies in his first episode, but the producers liked the performance so much that they made the character a clone so he could keep coming back.
Q 18Elim Garak, Deep Space Nine's Cardassian tailor, is a former agent of which secret police organisation?
The Obsidian Order
The Obsidian Order. Garak was one of its top operatives until he was exiled, and its feared chief, Enabran Tain, is later revealed to be his father.
Q 19Who plays Gul Dukat, Sisko's arch-enemy?
Marc Alaimo
Marc Alaimo. He had played the first Cardassian ever seen, on The Next Generation; as Dukat he hands Cardassia to the Dominion in order to make himself its ruler.
Q 20Which Cardassian, introduced as Dukat's aide, eventually leads an insurgency against the Dominion?
Damar
Damar, first seen as Dukat's aide in 'Return to Grace' (1996), later becomes Cardassia's Dominion-installed leader, then turns rebel and dies in the final episode leading the Cardassian uprising.
Q 24Which Klingon general becomes Chancellor after Gowron is killed in a duel near the end of Deep Space Nine?
Martok
Martok, played by J. G. Hertzler, becomes Chancellor in 'Tacking Into the Wind' when Gowron dies in a duel and the victor hands Martok the title rather than claim it.
Q 25Morn, the regular at Quark's bar, is famous for what?
Never speaking a word on camera
Never speaking a word on camera. The running joke is that everyone else calls Morn a chatterbox; he is named for Norm, the barfly of the sitcom Cheers.
Q 26Which piece of jewellery do Bajorans on Deep Space Nine wear as a symbol of their religious faith?
An earring
An earring. Its design once also showed a Bajoran's caste, a system so rigid that when a visitor from the past tries to revive it, Sisko warns it would bar his hosts from joining the Federation.
Q 27In 'The Way of the Warrior', DS9's effects team filled out the distant battle fleets with what?
Toys, model kits and Christmas ornaments
Toys, model kits and Christmas ornaments. Shop-bought Playmates toys, Ertl kits and Hallmark Bird-of-Prey ornaments stood in for far-off warships, because building that many studio models would have cost too much.
Q 28What do the Ferengi of Deep Space Nine hoard as currency?
Gold-pressed latinum
Gold-pressed latinum. The value is all in the liquid latinum; the gold is only a worthless casing that makes it easier to handle, as Quark learns when he ends up with bricks that have been drained.
Q 29Rather than follow his father into Starfleet, Jake Sisko chooses to become what?
A writer
A writer. Jake turns down a place at a writing school on Earth to stay on the station, and when the Dominion seizes it he stays behind to report on the occupation.
Q 30Into which original series episode were the DS9 crew digitally inserted for Star Trek's 30th anniversary?
The Trouble with Tribbles
The Trouble with Tribbles. In 'Trials and Tribble-ations' its villain Arne Darvin, played again by Charlie Brill, goes back in time to kill Kirk with a bomb hidden in a tribble.
