Atlantis (Stargate)

In the science fiction television series "Stargate Atlantis", the spin-off of "Stargate SG-1", Atlantis isa city-sized spaceship located in the Pegasus galaxy. Atlantis serves as the base of operations for the main characters, from which they explore other planets through the Stargate. According to the mythology of the show, the city was built by an advanced race known as the Ancients, and is the basis for the ancient Greek accounts of Lost City of Atlantis.

Background

Atlantis was built millions of years ago by the Ancients, who called it Atlantus. The city resided in Antarctica on Earth until five to ten million years ago, when a devastating plague prompted the Ancients to relocate it to the Pegasus galaxy. There, it served as the Ancients' capital as they built a new system of Stargates and seeded many worlds with humans. However, the Ancients' activities gave rise to a powerful new species, the Wraith. With their vastly superior numbers, the Wraith drove the Ancients from their holdings until only Atlantis was left, defended by its powerful shield and a network of armed satellites.sgcite|The Defiant One|Atlantis|show=ref] The Wraith laid siege to Atlantis for years; The Ancients submerged the city for protection but, unable to see a path to victory, eventually chose to return to Earth through the Stargate. There they merged with the native human population, and their accounts of Atlantis gave rise to the classical myth of the Lost City. Atlantis itself lied on the ocean floor, empty and dormant, for ten thousand years.sgcite|Rising|Atlantis|show=ref]

how history

The Lost City of the Ancients is first mentioned by Daniel Jackson in the season 6 finale of "Stargate SG-1", sgcite|Full Circle. In the episode, he directs SG-1 to a tablet that mentions Atlantis, and tells them that there are powerful weapons there capable of defeating Anubis. The search for the Lost City continues through season 7 of "SG-1", and although the team finds the Ancient outpost in Antarctica, the location of Atlantis itself remains a mystery. In the "Stargate Atlantis" premiere sgcite|Rising|Atlantis, Jackson discovers that the Stargate address to Atlantis contains eight symbols, meaning that it is in another galaxy. The multi-national Atlantis Expedition, led by Dr. Elizabeth Weir, is formed to investigate the city, with the knowledge that they may be unable to return as opening the wormhole will use up the last of the power in Earth's ZPM.

The Expedition arrives to find Atlantis still underwater; with power nearly exhausted, a failsafe releases the city and it rises to the surface. The episode sgcite|Before I Sleep|Atlantis reveals that the first time the Expedition arrived at the city, there was no failsafe and most of the personnel drowned. Weir, the only survivor, changes the timeline after traveling back 10,000 years, by convincing the Ancient Janus to help her ensure the survival of the city and her people. Atlantis is cut off from Earth for most of the first season, and must face an impending Wraith attack alone. In the season 1 finale sgcite|The Siege, Part 2|Atlantis, Earth reestablishes contact with Atlantis using a ZPM recovered from Egypt (detailed in the "SG-1" episode sgcite|Moebius), and sends supplies and reinforcements. The Earth ship "Daedalus" subsequently brings the ZPM to Atlantis in sgcite|The Siege, Part 3|Atlantis, but Atlantis only survives the Wraith attack by faking a self-destruct. Keeping the continued existence of Atlantis secret from the Wraith thus becomes a top priority in the following seasons.sgcite|Critical Mass|Atlantis|show=ref] The "Daedalus", newly fitted with an intergalactic hyperdrive, now provides a regular link between Atlantis and Earth.sgcite|The Intruder|Atlantis|show=ref]

In season 3, Atlantis is briefly reclaimed by a group of surviving Ancients in sgcite|The Return|Atlantis. The city then falls to the Asurans, and is finally retaken by Earth forces. The Atlantis Expedition recovers three ZPMs from the Asurans' occupation, two of which are taken to bolster Earth's other defenses.sgcite|Echoes|Atlantis] At the end of season 3, Atlantis comes under attack by an Asuran satellite weapon. McKay and his team figures out a way to activate the city's stardrive and escape, but the city runs low on power well short of its destination.sgcite|First Strike|Atlantis|show=ref] In the second episode of season 4, sgcite|Lifeline|Atlantis, the Atlantis team steals a ZPM from the Asuran homeworld to power the rest of their journey, and Atlantis touches down on a new world, M35-117. With Dr. Weir captured by the Asurans, Colonel Samantha Carter is appointed as the new Atlantis commander.sgcite|Broken Ties|Atlantis|show=ref] At the beginning of season 5, Carter is recalled to Earth and the IOA appoints Richard Woolsey as the new leader of Atlantis.sgcite|Search and Rescue|Atlantis|show=ref]

Layout

Atlantis is a huge, snowflake-shaped platform covered in skyscrapers; at the center is the central spire, the tallest building in the city. The central spire contains the main control room, referred to as Stargate Operations, and the Stargate itself. Rapid access throughout the city is provided by a network of transporter rooms. The underside of the city contains the massive engines that propels the city through space, as well as the docking point for an Ancient outpost.

According to Visual Effects Artist Bruce Woloshyn, the model of the city of Atlantis, when they first built it, was over four million polygons, which is feature film size. Thanks to this there is a lot of detail that they can back up, allowing the city to look really nice. Also they could get right up beside the buildings and there is still a large amount of detail. Also most of the city is modelled, not textured, which allows for the details to move when the city is turned around.DVD-Video "Behind the Gate" of the SGA Season 1 DVDs.]

Many sets used for Atlantis (and also SG-1) are actually part of a massive sound stage which was built for almost 2 million dollars. This large stage is used for rooms like the brig, several balconies including the ones with the grounding stations or other interior parts of Atlantis. If they require outdoor views they use green screens to hide parts of the set.DVD-Video "Behind the Gate" of the SGA Season 1 DVDs.] Also some sets of Atlantis are part of the set which was used for , for example the bridge seen first in "The Storm" or the infirmary in "Michael".

Areas

*Auxiliary control center This is a large room in the underground of the city. It allows people to control the city if the main operations center is unavailable. From this room a person can for example use the communications system or power up the city's star drive.cite episode| episodelink=The Tower (Stargate Atlantis)| title=The Tower| series= Stargate Atlantis| serieslink=Stargate Atlantis]
*Brig The brigs in Atlantis are used to lock dangerous people away. The brigs are rooms which have a cage in the middle. This cage is not only protected by horizontal running bars but also by a powerful force field which no one can penetrate. These fields only drop when the chamber is unlocked. The Atlantis expedition used the brigs several times to imprison captured Wraith and Genii.cite episode| episodelink=Suspicion (Stargate Atlantis)| title=Suspicion| series= Stargate Atlantis| serieslink=Stargate Atlantis] cite episode| episodelink=The Siege (Stargate Atlantis)| title=The Siege, Part 1| series= Stargate Atlantis| serieslink=Stargate Atlantis]
*Chair room Like the Ancient outpost in Antarctica, Atlantis also contains a control chair. It is used by Sheppard to control the city's drone weapons in sgcite|The Siege|Atlantis. It is also used to fly Atlantis in sgcite|First Strike|Atlantis and sgcite|Lifeline|Atlantis.
*Conference rooms Atlantis houses two known conference rooms, that allows the leadership to discuss important matters. The two known rooms are located right beneath the gate room. The smaller one is used for only a few people and it contains only a larger triangle shaped table with chairs. Another bigger one, which contains a longer table, is used for large meetings in which many people can take part. Each of these rooms can be accessed by multi-panel doors.
*Hologram room A room that allows access to the Ancient database in the form of holograms. In sgcite|Rising|Atlantis, it plays a message from the Ancient Melia describing their history in the Pegasus galaxy. Sheppard uses the room to show Colonel Evrett the galactic tactical situation in sgcite|The Siege|Atlantis. In sgcite|The Pegasus Project, Daniel Jackson and Vala Mal Doran use the room to search for information about planets where the Sangraal might be hidden. The Ascended Ancient Morgan le Fay poses as the teaching hologram she originally invented in order to give them the information. The room is relatively power-intensive and so is used sparingly.sgcite|The Siege|Atlantis]
*Gym An empty room which is used by the personnel to train. This room is often used by Teyla Emmagan, John Sheppard and Ronon Dex.
*Infirmaries Atlantis has several medical facilities. These rooms house many different medical devices, most of them from Earth but some from the Ancients. There are also possibilities for medical and biological research. The primary medical facility is a large room with several beds to treat and watch over many people. But there are also extra rooms like an adjacent room where people can recover as well as a single room for treating only one person while other people can watch from above through a large glass façade. The medical facilities were under the command of Dr. Carson Beckett. After Beckett's death, he was replaced as chief medical officer by Dr. Jennifer Keller.
*Jumper bays The main puddle jumper bay in Atlantis is a two-story located atop the central tower. The jumpers can exit either outside through a portal in the roof or into the control room to travel through the Stargate.sgcite|Suspicion|Atlantis|show=ref] The design of the jumper bay changes after the season 3 episode sgcite|The Return|Atlantis, in which Sheppard's team destroy much of the upper central spire. "The Return" also shows that there is another jumper bay accessible from the ocean underneath the city.
*Laboratories Atlantis houses a huge number of laboratories in which the Ancients were conducting many different experiments. Over time the Atlantis expedition stumbled upon some of them. These laboratories have contained an energy creature,cite episode| episodelink=Hide and Seek (Stargate Atlantis)| title=Hide and Seek| series= Stargate Atlantis| serieslink=Stargate Atlantis] a nanite virus,cite episode| episodelink=Hot Zone (Stargate Atlantis)| title=Hot Zone| series= Stargate Atlantis| serieslink=Stargate Atlantis] a stasis capsule containing an alternate version of Elizabeth Weir,cite episode| episodelink=Before I Sleep (Stargate Atlantis)| title= Before I Sleep| series= Stargate Atlantis| serieslink=Stargate Atlantis] , a human advancement device similar to a DNA resequencer,cite episode| episodelink=Tao of Rodney (Stargate Atlantis)| title=Tao of Rodney| series= Stargate Atlantis| serieslink=Stargate Atlantis] , a zoology lab,cite episode| episodelink=Echoes (Stargate Atlantis)| title=Echoes| series= Stargate Atlantis| serieslink=Stargate Atlantis] and a device that creates explosive tumors.cite episode| episodelink=Sunday (Stargate Atlantis)| title=Sunday| series= Stargate Atlantis| serieslink=Stargate Atlantis]
*Living quarters Since Atlantis can house many people there are also a lot of living quarters. Some are rather small, can only house one person and do not have much free space,cite episode| episodelink=Hide and Seek (Stargate Atlantis)| title=Hide and Seek| series= Stargate Atlantis| serieslink=Stargate Atlantis] while others are bigger and provide more room.cite episode| episodelink=Duet (Stargate Atlantis)| title=Duet| series= Stargate Atlantis| serieslink=Stargate Atlantis]
*Mess hall A large hall located halfway up the central spire where Atlantis personnel can eat or socialize. It has a spectacular view of the city.sgcite|Aurora|Atlantis|show=ref] sgcite|Sunday|Atlantis|show=ref]
*Outpost When Atlantis resided on Earth in Antarctica, it was docked with an Ancient outpost. The outpost is powered by a ZPM and contains a shield and a large number of drone weapons.sgcite|Lost City|show=ref] The outpost was left behind when Atlantis travelled to Pegasus. Another, similar outpost is found on Proclarush Taonas.
*Stargate operations The main control room of Atlantis, located in the central tower and containing all devices and control consoles to operate the city. Here the DHD of Atlantis is located (and the only one which can make a connection with Earth as it has a special control crystal to do so,cite episode| episodelink=Home (Stargate Atlantis)| title=Home| series= Stargate Atlantis| serieslink=Stargate Atlantis] ) as well as controls for the Stargate force field, city-wide communications,cite episode| episodelink=Hide and Seek (Stargate Atlantis)| title=Hide and Seek| series= Stargate Atlantis| serieslink=Stargate Atlantis] external communications,cite episode| episodelink=The Siege (Stargate Atlantis)| title=The Siege, Part 1| series= Stargate Atlantis| serieslink=Stargate Atlantis] energy systems, city-wide sensors, space and planetary sensors, access to the Ancient database and much more. Later a console is found and installed in the operations center which turns out to be a biometric sensor to scan the city.cite episode| episodelink=Sanctuary (Stargate Atlantis)| title=Sanctuary| series= Stargate Atlantis| serieslink=Stargate Atlantis] In the direction of the gate room, the center is enclosed with a glass façade and a balcony, which allows the people to watch the gate area. Lastly the room provides access to the Puddle Jumper bay and a balcony at the backside.

Technology

The city holds many secrets and technology far in advance of that mastered by the human expedition. In regular use are the transporters to move people and objects around the city and the Puddle Jumpers docked in Atlantis. But the city has not been fully explored due to its size, and search teams are finding new rooms and technology every day.

Computers

Atlantis holds a huge database of Ancient knowledge. Even with all the hard drives the Atlantis expedition brought with them and using an efficient compression codec invented by Dr. McKay only about 9% of the translated database could be stored. The database holds a collection of Stargate addresses for both Pegasus and the Milky Way,cite episode| episodelink=Rising (Stargate Atlantis)| title=Rising| series= Stargate Atlantis| serieslink=Stargate Atlantis] information about the Wraith, the Iratus bug,cite episode| episodelink=Conversion (Stargate Atlantis)| title=Conversion| series= Stargate Atlantis| serieslink=Stargate Atlantis] information about other species,cite episode| episodelink=Trinity (Stargate Atlantis)| title=Trinity| series= Stargate Atlantis| serieslink=Stargate Atlantis] and much scientific research, including zero-point module research, work on ascension, weapon schematics and notes on space travel. The database also has an incredible ability to back up data, so deleting it is difficult. The database can be accessed through many database terminals in the city.cite episode| episodelink=The Siege (Stargate Atlantis)| title=The Siege, Part 1| series= Stargate Atlantis| serieslink=Stargate Atlantis]

Defenses

The main defense system of Atlantis is its energy shield, without which the city is surprisingly fragile.sgcite|The Storm|Atlantis|show=ref] While the shield can effectively hold back almost any threat, it consumes so much power that a ZPM is required to activate it.sgcite|Rising|Atlantis|show=ref] In sgcite|The Eye|Atlantis, McKay uses the energy of multiple lightning strikes to briefly power the shield. The Ancients once extended the city's shield over much of the hemisphere in order to protect the native life against a coronal mass ejection.sgcite|Echoes|Atlantis|show=ref] In sgcite|The Siege, Part 3|Atlantis, the Atlantis Expedition links the cloaking generator of a puddle jumper to the city's shield generators, converting the shield into a cloak. This is used to fool the Wraith into believing Atlantis has been destroyed,sgcite|The Siege, Part 3|Atlantis|show=ref] and is used in subsequently episodes to hide from the Wraith.sgcite|Critical Mass|Atlantis|show=ref] sgcite|Allies|Atlantis|show=ref] In sgcite|The Return|Atlantis, the Atlantis team modifies the shield generators to emit a replicator disruptor wave.

The primary weapons of the city are drone weapons, which require the Ancient control chair to fire. At the time of sgcite|The Siege|Atlantis, Atlantis has only a few dozen drones left, which are all used in defending the city against the Wraith. The city's drone supply is replenished from the stores of another city ship discovered in sgcite|The Tower|Atlantis. The SGC has also installed multiple railgun, machine gun, and SAM missile emplacements.sgcite|The Siege|Atlantis|show=ref]

Power

Atlantis is powered by three Zero Point Modules, though most systems can function with just one. The Atlantis Expedition has installed a series of naqahdah generators, which are sufficient for basic systems. The city also has solar power generators that can power minor systems.sgcite|The Last Man|Atlantis|show=ref] Power is distributed throughout the city via conductive conduits lining the walls of every corridor. The city will automatically power up sections when people enter them, and can also make some system adjustments to compensate for low power.

Propulsion

Atlantis' stardrive allows the city to achieve orbit and travel between galaxies via hyperspace. To protect its inhabitants during flight, the city is equipped with inertial dampeners.sgcite|Critical Mass|Atlantis|show=ref] The city is flown from its Ancient control chair.sgcite|First Strike|Atlantis|show=ref] sgcite|Lifeline|Atlantis|show=ref] The power requirements of the stardrive are enormous. In sgcite|First Strike|Atlantis, the Atlantis Expedition is able to launch the city with a single ZPM by adding additional power from an Ancient geothermal drilling station during the first few minutes of lift-off. However, Atlantis runs low on power before it reaches its intended destination, due to damage to the power distribution system.

ensors

The city is equipped with several types of sensors: first the long-range sensors which allow Atlantis to scan distant star systems. Thus the inhabitants can find out whether ships are on their way to the city and thus are warned if the Wraith are coming.cite episode| episodelink=The Brotherhood (Stargate Atlantis)| title=The Brotherhood| series= Stargate Atlantis| serieslink=Stargate Atlantis] cite episode| episodelink=Inferno (Stargate Atlantis)| title=Inferno| series= Stargate Atlantis| serieslink=Stargate Atlantis] This set of sensors ran in the background and was discovered months after the arrival of the expedition. Another set of sensors are the internal sensors, which display detailed plans of the city and life-forms in it. Although it can distinguish between organic and energy life forms,cite episode| episodelink=Hide and Seek (Stargate Atlantis)| title=Hide and Seek| series= Stargate Atlantis| serieslink=Stargate Atlantis] it cannot differentiate between organic life forms.

The third set of sensors are the biometric sensors that scan the city for irregularities in biometric rhythm. If people of different species are in the city, the sensors detect them.cite episode| episodelink=The Siege (Stargate Atlantis)| title=The Siege, Part 1| series= Stargate Atlantis| serieslink=Stargate Atlantis] These sensors were discovered by the Atlantis expedition about one month before the arrival of the Wraith.cite episode| episodelink=Sanctuary (Stargate Atlantis)| title=Sanctuary| series= Stargate Atlantis| serieslink=Stargate Atlantis] However the biometric sensors need a lot of power so they were ordered to only scan the gate room.

Transportation

The transporters are the primary means of transport to move quickly between different parts of the city.cite episode| episodelink=Hide and Seek (Stargate Atlantis)| title=Hide and Seek| series= Stargate Atlantis| serieslink=Stargate Atlantis] They are small chambers and if someone enters, a console opens in the back and reveals a map of the city with red lights that display the location of the other chambers. To be transported to another chamber a user only needs to press one of the red lights at the target location. Afterwards the people in the chamber are transported to this location in a blinding flash of light. This system functions in a similar manner as the Ring Transporters which doesn't come as a surprise since both systems were invented by the Ancients. The chambers also function as elevators to move people up and down in the same structure or building.

Miscellaneous

Atlantis experiences frequent lightning strikes; for protection there are lightning rods throughout the city, which channel the electricity to four grounding stations that lead into the ocean.
