Generational Ships

systems___cryogenics_1Ever since my writing group and I got on the subject of space and colonization, some recurring themes have come up. For starters, there’s the concept of interstellar space travel, the kind that doesn’t involve fictitious Faster-Than-Light drive systems and therefore cannot exceed the speed of light. In those situations, which are far more likely to happen in this and the next century, the question of how to keep crews alive until your arrival keeps popping up.

One way is to utilize some kind of cryogenic procedure, where passengers are put into “reefersleep” for the duration of the journey and awakened upon arrival. Though it might sound a bit crude, it’s actually a very practical solution to the problems of how to keep a crew preserved and provided for during the incredibly long voyages that space travel entails. This procedure has come up repeatedly in the realm of science fiction, particularly H.P. Lovecraft’s Cool Air, Robert A Heinlein’s The Door into Summer, Clarke’s 2001: A Space Odyssey, PKD’s Ubik, the Alien franchise, and the Revelation Space universe, just to name a few.

RAMAThe other solution, which is the subject of this post, is to construct generational ships. These are basically “interstellar arks” where people and even entire biospheres are transported from one location to another. Crews are kept in waking conditions, experience subjective time, and entertain themselves in interactive, simulated or virtual environments in order to stay sane until they complete their voyage. Though much more expensive to build, these ships are an equally elegant solution of what to do about non-FTL space travel and colonization.

These two have made many appearances in science fiction, and I’ve compiled a list of all the Generation Ships, Space Arks, and O’Neil Cylinders I could find.

Firefly:
At the beginning of each episode, it was explained how Earth was used up, prompting humanity to seek out a new home. This is what eventually led them to 34 Tauri  in the 22nd century where they began the process of terraforming and settling its the many worlds and moons. Though it was never explained in detail, mainly because the show was cancelled before they could (screw you Fox!), indications are given in the movie Serenity and the expanded universe that this involved Generation Ships.

In the movie, this was done mainly through visuals, where a large of flotilla dusts off from Earth and eventually finds its way to the system of the White Sun. It was also said that the process of terraforming took decades, which would require that the crews had somewhere to stay while the terraformers did their work. Also, speculative point here, but it would stand to reason that the fleet would have to have some pretty large ships to accommodate both settlers and the kind of equipment they would need.

Chasm City:
This novel, set in Alastair Reynold’s Revelation Space universe, involves a large thread that follows the settlement of the world known as Sky’s Edge. This took place early in the universe’s backstory, before the development of lighthuggers and therefore required that the ships used be able to support crews for long periods of time.

From Reynold’s descriptions, these ships were large, cylindrical vessels that boasted vast bays to hold their many cryogenically-frozen passengers. At the same time, the waking crew needed vast facilities to provide for their needs. These included mess halls, sleeping quarters, medical bays, and recreational facilities. Sky Haussmann, one of the children amongst the crew, had a nursery with a robotic clown and virtual backgrounds.

This divide, between a waking crew and frozen settlers, represents a sort of compromise between the cryoship design and the generation ship. On the one hand, you’ve got the majority of your crew at near-frozen temperatures and perfectly preserved for the voyage. On the other, you’ve got a crew walking about and looking for food, rest and entertainment. However, it still qualifies, and even inspired my group in our quest to design the perfect story for colonization!

Orphans of the Sky:
One of the earliest known examples of the use of generation ships in sci-fi, this two-novella set was also one of Heinlein’s first works. Like Clarke’s Rendezvous with Rama, it features a massive cylindrical ship that is drifting through space. But unlike Rama, Heinlein’s ship, known as the Vanguard, has become a derelict that is permanently adrift in space.

As the story goes on, we learn that this was due to a mutiny which killed all the piloting officers many generations back. Since that time, the descendants of the surviving loyal crew have forgotten the purpose and nature of their ship and lapsed into a pre-technological culture marked by superstition. In fact, they now view their ship as the cosmos itself, and interpret its “voyage” as a metaphor.

The crew are also ruled by an oligarchy of “Officers” and “Scientists”, at the head of which is the descendent of the original captain. Much like pre-industrial times, most crew members are dedicated to a simple life where they tend to agriculture and are illiterate. Seldom does anyone ever venture to the “upper decks” where the “muties” (aka. “mutants” or “mutineers”) are kept. These individuals, it is learned, know the truth of the ship’s purpose, another reason why they are ostracized from the rest of the crew.

As you can plainly see, this book not only featured a generation ship and some rather hard science when it came to colonization, it also raised some valid and interesting questions about how space travel and confining environments could effect subsequent generations of people. Those who were born into an enclosed environment would come to know it as their whole world. And in the absence of external, verifiable facts (such as messages from Earth or historical records), they could even be led to believe there was nothing beyond their walls.

Paradises Lost:
Similar in tone and setting to Heinlein’s Orphans, this story by Ursula K. LeGuin focuses instead on the psychological impact that generational travel would have on a human crew. Adapted into a musical, this story explores the basic question of what happens when you spend your whole life (and entire generations) traveling toward a goal, only to find that the endpoint has become otherworldly and unattainable?

The story takes place aboard a generation ship known as the Discovery, where people are born and die on a trip to colonize a distant planet. Much like the Orphans, the ship becomes their entire universe and begins to seem more tangible to them than Earth or their mission to colonize a new world. The reason for this quite simple; as the journey goes on, those who knew a life on Earth are slowly dying off, and subsequent generations know about these things only through tales and lore.

As a result, a new religion is borne which teaches that the ship is “spaceship heaven” and that it is bound for eternity. This religion is known as Bliss, and the younger generation are embracing it against the wishes of the older. The story is told through the eyes of two elder characters – Hsing and Luis. They know their lives will end on board the ship and that their mission lies in the hands of future generations. Naturally, they worry since said generations are convinced that they should never leave the ship they call heaven.

Rendevouz with Rama:
One of the best examples of a generational ship, which extra-terrestrial in origin! Known as Rama, this massive space cylinder was basically a self-contained world that was carrying the Raman civilization from one corner of the galaxy to another. When a crew from Earth arrive and begin to survey the interior, they begin to notice several tell-tale features.

For one, the interior contains several structures which appear to be arranged in “cities” – odd blocky shapes that look like buildings, and streets with shallow trenches in them, looking like trolley car tracks. In addition, there is a sea that stretches in a band around Rama dubbed the Cylindrical Sea, and trenches cut into the sides that appear to be windows.

In time, all the machinery comes to light, thanks in part to the admission of light through the ship’s long windows. Small creatures that appear to be biological machines (aka. “biots”) begin to come out as well and conducting routine maintenance. In time, they come to the conclusion that the buildings constitute factories, that the cylindrical sea contains trace elements and bio-matter which they will begin to convert into “Ramans” as soon they get in range of their destination.

In the end, it seemed that the Ramans determined that the best way to spread their species was to break them down into their component parts, place them aboard ships that would float for generations through space, and begin recompiling them once they got to where they wanted to go. Ultimately, Sol was just a stopover on their long journey, and more ships were coming in subsequent novels. Still, this first exposure to the alien generation ship was an educational experience!

Ringworld:
Written by Larry Niven, the Ringworld series is considered one of the greatest examples of exploratory sci-fi. Set in the Known Space universe of the distant future, the story revolves around the discovery and exploration of the Ringworlds, an artificial habitation ring built by an extinct civilization. With the makers of these rings long dead, the rings themselves are adrift and their engineered inhabitants degenerated into a primitive state.

These artificial rings are roughly one million kilometers wide and one thousand kilometers across, approximately the diameter of Earth’s orbit. Each one encircles a Sol-type star which provides both life sustaining energy and light. And of course, they rotate, thus providing artificial gravity that is 99.2% as strong as Earth’s through the action of centrifugal force. And night is provided by an inner ring of shadow squares which are connected to each other by thin ultra strong shadow square wire.

The ringworld has a habitable flat inner surface that is equivalent in area to approximately three million Earth-sized planets. Hence, it is able to sustain extensive ecosystems and all forms of life. This appears to be purpose of the rings in the end, the creation of habitable areas in space that were removed from terrestrial environments. And added bonus was the ability to transport said life over vast distances through space without having to stick them in an enclosed environment.

So really, these things were like a gigantic version of a generation ship, capable of moving an entire species or civilization through space.

Stargate Atlantis:

The series Stargate Atlantis contained a few mentions of vessels which fit the profile of generation ships. For starters, there was the Ancients City Ship, a self-contained city that was also a spaceship. Though it was capable of FTL travel, the vessel was capable of sustaining a city-sized population for extended periods of time as it traveled through space.

In addition, in the third season episode entitle “The Ark”, Colonel Sheppard’s team discovers a facility inside a hollowed-out moon that turns out to be an ark created by the people of the planet around which the moon is in orbit. The ark was built to preserve the existence of the people from the planet so that they could reemerge and rebuild their civilization. Generations prior, these people had fought a disastrous war with the Wraith in which they were almost exterminated.

Though not a vessel per se, the moon base served the same purpose as a generation ship. Though the moon orbited their original homeworld and the people really weren’t traveling through space (except in orbit around their planet), the principle was essentially the same. People were kept in stasis until the day came when they could awaken to transplant themselves on the intended world, thus ensuring the survival and expansion of their civilization.

Yes, the examples abound! In fact, the concept of the generation ship and related ideas are so fertile that I’m kind of surprised that it took me so long to really appreciate it. But then again, I came to a lot of the classics a little late in life. Ah well, it doesn’t really matter when you get to the destination, provided that you get there and enjoy the journey. Which is kind of the concept behind a generation ship isn’t it? If you can’t just warp your way across the universe – if you got to take your time and drift slow – you might as well travel in style!

Cool Ships (volume IV)

Back with a fourth installment. As usual, I am indebted to people for making suggestions and offering critiques. Funny thing, these lists seem to be getting longer and more diverse the longer this series goes. But I guess that tells you something about the world of sci-fi. No shortage of material, and kind of like fossil hunting in that the deeper you dig, the more fascinating things get.

Ancients City Ship:
You know the old saying “you can never go home”? Well in this case, the Ancients seemed to think that the best away around that was to take it with you. This one goes out to Nicola Higgins. Thanks for the suggestion, you Stargate fangirl!

Known as a City Ship, this piece of Ancients technology is in centerpiece of the spinoff series Stargate: Atlantis. A self-contained city that is capable of traveling through space, and comes equipped with a hyper drive, this vessel was designed to transplanting colonies of Ancients on distant worlds throughout the Galaxy. It also heavily armed and shielded, making it a veritable mobile fortress.

Beginning several million years ago, the Ancients began what was known as the “Great Migration”, where they left Earth for the Pegasus Galaxy and other destinations in deep space. One such ship which took part in the migration was the Atlantis, which departed from Antarctica and landed on the world known as Lantea, where it was again discovered by humans in the course of the show.

Measuring roughly the same size as Manhattan island, an average city ship comes equipped with extensive living quarters and amenities that make it suitable for large-scale population for extended periods of time. Though capable of space flight and space combat, it’s environment of choice is terrestrial, preferably on water.

Colonial Viper:
This one kind of seems overdue. But I felt the need to push this one back so I could cover the bigger ships from the Battlestar Galactica franchise first. With them done, I can now pay tribute the fighter-craft of choice for the Twelve Colonies, the Viper! Taken from the original series, the Mark II was your basic space superiority fighter, fast, maneuverable, and boasting two laser guns for defense.

In the updated series, the Mark II was considered a relic from the Human-Cylon War, its systems outdated and its controls antiquated (the laser guns were also replaced by two ballistic weapons and a compliment of missiles). However, it was these very antiquated features that would prove to be the saving grace of the Mark II when the Cylons attacked the Colonies at the beginning of the new series.

The updated Mark VII Viper was the pinnacle of Colonial technology at the time. Boasting updating targeting, controls, all of which were networked with the fleet’s central computer system, the Mark VII was far more sophisticated than its predecessor in every measurable way. However, being a networked fighter made it vulnerable when the Cylons unleashed their crippling virus on the Colonies defense mainframe. Several models remained in operation though, thanks in large part to the Pegasus surviving the initial Cylon assault. Once the two fleets combined their resources, the Colonial fleet had several Mark VII’s at their disposal and even began manufacturing new ones to replace their losses.

The Colossus:
Now here’s a franchise I haven’t covered yet! Fans of Freespace and FS II know that when it comes to cool ships, there was no shortage to come out of this video game series. Classically inspired, well-designed and just plain awesome to behold, the Colossus is definitely top of that list. Big, bad, and boasting enough firepower to take down an enemy armada, the Colossus was appropriately named!

Designed by the Terran-Vasudan Alliance in the wake of the Great War, the Colossus was a prototype super-destroyer that was designed to confront all future incursions by a hostile race. Foremost amongst these was the threat of the Shivans, the species that appeared in the first game, destroyed the Vasudan homeworld and nearly destroyed Earth as well.

Measuring 6 km in length, bristling with weapons and boasting a crew of over 30,000, the Colossus took over 20 years to complete and involved dozens of contractors from both races. In terms of defense, it has over 80 weapon turrets, consisting of cannons, missile launchers, and multiple heavy beam emitters. It also houses 60 fighter and bomber wings and requires a crew of over 30,000. In short, the Colossus wields more firepower and fighter wings than an entire Terran or Vasudan armada.

Deimos-class Corvette:
You know the old saying, “it’s not the size of the dog in the fight but the size of the fight in the dog”? That’s what comes to mind whenever I see small ships that are solidly built and pack a wicked punch. As you might have guessed, that precisely what the GTCv Deimos-class vessel is all about! Also taken from the Freespace universe, this corvette was designed for fighter support and attack purposes, providing some added firepower and punch to light assaults and defensive screens.

As the newest addition to the Terran fleet in FS II, these corvettes were designed to replace the aging Fenris and Leviathan-class cruisers from the Great War. In addition to their small profiles and heavy firepower, their hulls are strengthened with collapsed-core molybdenum sheathing for better protection against beam fire and their Vasudan-designed reactor core provides more energy per ton than any other allied ship class.

In a way, these ships remind me of the USS Defiant. Much like that little ass-kickers from the DS9 universe, she packs a lot of power and toughness into a small frame, proving that you don’t have to be big to bring a big ass-whooping! As you might be able to tell, this is a bit of a vicarious experience for me 😉 Being only 5’8”, I too had to be known for scrappiness whenever height and reach failed me in a sparring match!

Drakh Raider:
Once more onto B5 friends. God, I worry people are going to get so sick of this universe given all the attention I devote to it. But as long as it keeps providing ’em, I’ll feel obliged to honor ’em! This time, it’s the Drakh Raider which I’ve chosen to represent. Small, sleek, fast and powerful, these ships were the first line of assault and defense for the Drakh fleet, providing attack screens and defensive escort to their larger destroyers and carriers.

As Londo remarked in the course of the show, “They’re a legend. The kind you would use to frighten small children at night... They were ruthless, savage, but extremely bright. A very bad combination.” And these ships certainly embodied that. Making their first appearance in the third season (“Lines of Communication”) when it became revealed that the Drakh were manipulating the Mimbari into a civil war, and later in the Call to Arms TV movie when the Drakh began assaulting Earth.

Being quite small and based around a central beam weapon, these ships were either unmanned or had a very small crew. They were also quite effective, as two were able to destroy a White Star during their initial encounter with Delenn and the Alliance fleet. However, being small and light, they were also relatively easy for more sophisticated ships of the Alliance to shoot down, and even a small fleet of them could not stand up to larger vessels like the Excalibur. Still, these puppies could wreak havoc against shipping and military vessels that belonged to the younger races. Once they began conducting raids on League Worlds, all parties were forced to turn to Sheridan and the White Star fleet for help.

Romulan Warbird:
Also known as the D’deridex-class, the Warbird class was one of the largest and most powerful ships in the Romulan Star Empire’s armada and served as the backbone of the Romulan fleet during the latter half of the 24th century. In addition to its impressive array of disruptors and photon torpedo banks, the Warbird also has a cloaking device, the result of military exchanges between the Klingon and Romulan Empires.

After their debut in the first season of TNG (“The Neutral Zone”), the Warbird went on to appear in several engagements with Star Fleet (most notably the Enterprise) and the Dominion. In the spinoff series of D29, they would figure prominently in the Dominion War. Initially, this consisted of providing defense against Jem’Hadar incursions, but eventually went on to take part in most major offensives. These included the battles of Chin’toka and the final assault on Cardassia Prime.

Measuring twice as long as a Galaxy-class starship (such as the Enterprise D) the Warbird is powered by a forced quantum singularity and boasts the latest in Romulan technology. This makes it not only one of the most advanced ships in the Romulan fleet, but the Alpha Quadrant itself!

Rama:
Once again, I find myself looking back and wondering how the hell I forgot this one. You can’t call yourself an Arthur C. Clarke fan and a sci-fi geek without knowing about Rama. Lucky for me, ongoing segments give us chances to correct for our mistakes, which I am doing now.

Taken from Clarke’s famous novel Rendezvous with Rama, this namesake was what can be termed a “generational ship”, meaning a spaceship where successive generations of people are expected to be born and die before it finally reaches its destination. In the course of the story, this massive ship was detected on its way towards Earth. Once scientists and astronomers learned that it was not an asteroid or some other natural phenomena, they became mighty interested mighty fast!

Basically a large cylinder in space, the ship measured 50 km in length, 16 km wide, and rotated in order to provide gravity equal to 0.25 g’s (or a quarter of what we’re used to here on Earth). After boarding it, astronauts from Earth noticed an interior layout that resembled cities, rivers and other common geographical features, but being based on technology and chemical compositions which they could not recognize. The horizontal sections of the ship also housed windows which appeared to be letting in outside light, which in turn was having a thawing effect on the landscape since it was frozen from being in deep space for so long.

In addition, they discovered that their was no crew to speak of, nor any cryogenic tanks that held them in stasis. Evenutally, it was determined that these chemical rivers contained the trace chemicals needed to “manufacture Ramans”, and that as it neared a star, it would take the energy and heat necessary to perform these and other life-restoring functions. In the end, Rama was just passing through, a grave disappointment for Earth people… until they realized that more were on the way!

Pretty damn cool huh? This concept of a cylindrical hull with a self-contained city went on to inspire countless franchises and writers, not the least of which was J.M. Straczynski who modeled the interior of Babylon 5 based on Clarke’s descriptions. Generational ships also appear in many science fiction franchises, not the least of which are Alastair Reynold’s Revelation Space series and Joss Whedon’s Firefly.

USS Saratoga:
Space Above and Beyond is back for another installment, this time with the main ship of the fleet! Designated as a SCVN (Space Carrier Vehicle Nuclear) the USS Saratoga is the futuristic equivalent of a modern-day aircraft carrier and was home to the 58th Squadron (“The Wild Cards”) for the entire series.

In the course of the show, the Saratoga served on the front lines for the entire Chig War. This included the defense of Earth in the pilot episode, the offensive at Ixiom and Deimos, and in Operation Roundhammer – the assault on the Chig homeworld – at the end of the series. For the duration of its service, the Saratoga was commanded by Commodore Glen Ross, a no-bullshit naval officer who enjoyed playing guitar, cared deeply for his people, and was known for his catch-phrase “take that bird out of my sky!”

In addition to its compliment of fighters, the Saratoga boasted some pretty heavy armaments, including laser pulse cannons, phalanx missile launchers, and anti-ship torpedos. The vessel was also powered by a helium 3 fusion engine, measured 525.6 m in length and was capable of FTL travel thanks to a wormhole-generating engine technology.

Tigers Claw:
Yet another franchise I have neglected to include so far, but which deserving since cool ships was kind of their thing… Here we have the TCS Tiger’s Claw, the carrier and command vessel from the video game series Wing Commander. In the first installment in the series, the Tiger’s Claw was as the focal point of the story, a Bengal-class carrier that was deployed to the Vega Sector to fight in ongoing conflict known as the Terran-Kilrathi war.

In the course of its deployment in the Vega Sector, the Tiger’s Claw participated in many successful campaigns. These included the destruction of the Kilrathi base of operations for the entire sector in the campaign known as Custer’s Carnival, and the destruction of the KIS Sivar in what was known as the Goddard Campaign.

Unfortunately, after proving victorious in Vega, the ship was transferred to the Enigma Sector where it was destroyed during an assault on the Kilrathi starbase K’tithrak Mang. Using stealth fighters, the Kilrathi managed to ambush and then obliterate the carrier using torpedoes. These events took place between the first and second installment in the series and formed the basis of the latter’s backstory. Save for the main character of the story – Col. Christopher Blair (aka. you) – all hands aboard her were killed, including her air group commander, General Halcyon.

In addition to its vast compliment of 104 fighters, the Tiger’s Claw also possesses 8 heavy laser turrets, 20 defensive batteries, and powerful shields. Measuring 700 meters in length and weighing over 80,000 tons, her crew numbers in the thousands. Although slow and lumbering compared to smaller craft, she is still capable of a high maximum velocity (468,000 km/hour) and can make FTL jumps.

Voth City Ship:
Here’s another example of something the Star Trek franchise did really right! Appearing in the third season of Star Trek: Voyager (episode 64: “Distant Origin”), the Voth City Ship was something that was both intriguing and heavily-inspired. Based on the concept of a self-contained city in space, she was the command and administrative center of the entire Voth race and home to its ruling matriarch.

As the episode which featured her progressed, we learn that a group of alien scientists have discovered Voyager and have become convinced that she holds the key to proving their “Distant Origins” theory. When they meet these creatures, they learn that their kind evolved from dinosaurs on Earth to become a race of talking, bipedal humanoids who developed an entire civilization before they were forced to flee. After millennia of wandering, they landed in the Gamma Quadrant where they have since become the dominant power.

Unfortunately for said scientists, and the crew of Voyager, the Voth leaders are not too crazy about this idea. In addition to contradicting their beliefs that they emerged in the Gamma Quadrant (known as “Doctrine”) they are insulted to think they are related to mammals, creatures they consider inferior. Once they make contact, they are able to capture Voyager and neutralize her defenses quite easily, beaming the entire ship into one of their massive internal bays and knocking out all of their equipment using a dampening field.

In addition to all this impressive technology, the Voth also appeared to possess cloaking technology, trans-warp capability, and no doubt had some serious mother-loving weapons technology. It was a major blessing that Janeway and her crew didn’t press matters too hard and try to get into a firefight with these aliens, otherwise we would have seen some serious fireworks.

Final Thoughts:
Woo! Okay, that one was pretty good. And some rather new and unique examples made it in this time. Thanks for the suggestions people and my endless thanks as always to the good folks who maintain the Wiki’s and other source info sights for these franchises. Without you, I’d be very limited and would have quite doing these long ago! Also, I seem to have focused on city and generation ships a lot in this posting, which got me thinking…

It was the physicist and mathematician Freeman Dyson who claimed that the pinnacle of technology would be the ability to build a “Dyson’s Sphere”. That is, a sphere so large that it could encompass an entire star system, or at least the star and its primary planets. After all, the amount of materials and engineering capabilities required to build such a thing are just staggering and clearly beyond the means of anything we now know. Now that all may be true, but might I suggest that a more realistic and attainable measure of technological prowess would be the ability to create self-contained environments where several successive generations of humans and animals could survive for long periods of time?

Think about it. A species that can do this would be capable of leaving whatever world they call home behind and transplanting themselves in a distant star system or galaxy, meaning that their fortunes would never be tied to one rock in one star system. Even if our survival didn’t depend on it – which it might given the state of the planet! – it would still be a rather elegant way of planting the seed of humanity elsewhere in the galaxy. Instead of sending people out land on a planet and then do all the hard work of terraforming and building infrastructure, you just send the ship, and people can grow outwards in their own time without having to worry about hostile environments or organisms.

Pretty anthropocentric, I know. And yes, colonization is chock full of potential for evil, especially where indigenous life is concerned. Still, it’s a cool concept and it got me thinking, which is partly why I like to do these things. An excuse for research and to expand my mind!

Until next time, keep those idears coming!
