Moss, who also created a clever series of black and red movie posters, and recently designed the brilliant, Hitchcockian Lost Locke poster, drew up this handy survival guide for the A Life Well Wasted podcast. This, and other posters by Moss, will be available in the podcast's store.

We looked at over 300 science fiction and fantasy television shows from 1970, the year after the original Star Trek series ended, to the present. In this chart, we list a few of the most iconic shows, but those are just a sampling of the hundreds we surveyed.

Then we looked at which shows on the air in any given year featured any one of the most common science-fiction themes: aliens, space travel, robots, time travel, and magic.

(Shows that contain multiple themes were counted once in each category, so Star Trek: The Next Generation would add one point each to aliens, space travel, robots and time travel.)

One thing the graph tells us is that the popularity of the different themes are increasingly linked as time goes on. Space travel and aliens are closely linked throughout the graph, since shows about space travel almost always include aliens, but as the graph transitions from the 1970s into the 1980s, shows with robots are increasingly linked to shows with aliens. This is in part because the more recent shows featuring robots and more recent shows featuring aliens are more likely to be one and the same, whereas in the 1970s, shows like Batman and The Bionic Woman would feature artificial intelligence but not extraterrestrials.

But it's interesting to note the way magic trends as well. In 1970, the gap between shows featuring magic and shows featuring more science-based themes is fairly wide, which may be related to the relative cost of producing the different types of shows; Captain Kirk required pricey sets and a makeup crew while Samantha Stevens just needed a film editor and the ability to wiggle her nose. But as audience expectations for shows involving magic become analogous to their expectations for science fiction shows, magic's peaks and valleys start to correspond to those of other themes, though supernatural shows may be a bit more resilient to overall drops in television spending.

The time-travel line is especially interesting, less for what it indicates about the popularity of time travel than for what it says about the variety of stories being told. Although time travel is sometimes the focus of a show (as in Quantum Leap or Seven Days), it more frequently appears in a handful of episodes of a show that tells a diverse set of science fiction or fantasy stories. Shows like the various Star Trek series, Lois and Clark, and even Xena feature the occasional obligatory time travel episode.

But the graph's most striking feature is the boom all the themes apparently experienced in the 1990s, and which now seems to be on the decline. It seems to suggest a huge investment in genre television shows (and perhaps in television in general) that we simply aren't seeing any more.

Interestingly, space travel shows were the first to go as circumstances changed, and although shows about managed to hang on longer, they, too are on their way out. Does this indicate that science fiction and fantasy shows are on the decline? Or does it represent a shift to less expensive, near-future science fiction with different speculative priorities, shows like Dollhouse, Chuck, and Fringe?

Here is a full list of all the shows we surveyed to create this chart.

Graph by Steph Fox and additional reporting by Alexis Brown.

David McCandless created this visualization as part of his upcoming book of chart porn, The Visual Miscellaneum. Here, he charts the temporal paths of different TV and movie time travelers (Doctor Who was omitted for the sake of sanity, though he hasn't ruled out making a separate chart for the Time Lord), and, just for fun, imagines what might happen if time travelers who landed in the same year happened to meet up (I suspect that, despite his ingenuity, Marty McFly would not fare well against the Terminator). McCandless did feel that his research revealed one key deficiency in time travel stories: nearly all time travel journeys he mapped originate and land between the years 1900-2100.

Mostly we've focused on movies from the U.S. and Europe, and we've included the living dead among zombies — so mummies are included, but vampires and ghosts aren't. Obviously as you look at this chart, you have to correct somewhat for the fact that more movies are being made as we get closer to the present, and (more importantly) there are better records of those movies with better tagging. So it's easier to research movies with zombies in them if you're looking at productions from the 1980s onward. In addition, there's been a huge boom in indie and low-budget horror movies over the past ten years, and that undoubtedly accounts somewhat for the giant spike you see during the last 8 years or so.

Still, even correcting for the fact that there are more movies being made today, you can see that there are distinctive spikes in zombie popularity - and they always seem to fall slightly after a huge political or social event has caused mass fear, chaos, or suffering. That's why World War II, Vietnam, and the current Iraq War are all followed by a zombie rush at theaters. Obviously, if you're going to look at these historical correlations, you have to consider that movies inspired by a real-life event aren't going to show up in theaters for at least six months to a year, so we've accounted for that.

You can see that most of these spikes in zombie popularity do seem weirdly close to periods of historical trauma like wars or the AIDS epidemic. Is there a causal connection, or is it just coincidence? You be the judge.

We've labeled all the futuristic features of this home, and color-coded it so you can see which gadgets don't exist (red), sort of exist (yellow), and are in your kitchen right now (green). Below, you can see which movies each device came from, and a bar graph that measures how many greens the movie got vs. reds. We also included domestic vehicles like cars in our "home of the future."

The documentary New Horizons turned out to be most accurate — at least when it came to domestic improvements that are possible with modern technology. This reel commissioned by General Motors focused on realistic advances in the automotive industry, looking only 20 years ahead. After all, why overreach? Googie’s had yet to be built in its landmark style, and human spaceflight was but stardust in scientists’ eyes.

In all the flicks, two of the most accurately-predicted items were large screen TVs and videoconferencing. Wireless technology, implied often by The Jetsons, is now ubiquitous. Less popular devices available today include the Master Cook (in the form of kitchen computers), fins on cars, and thumbprint entry.

Though the Scene Screen doesn't exist as such, it gets a yellow because it could be created by the do-it-yourself crowd. Just set up a projector display for your window. And you can create a Garden Center by winching a hydroponics rig above your dining room table.

In the red zone are a lot of technologies we wish we had — or maybe not. You’ll have to wait for the three seashells, walk-in Orgasmatron, and gigantic fruit (though we’re already genetically modifying produce) — but anti-grav space boots probably aren’t on the way anytime soon.

Of course, what would a piece on everyday life in the future be without mention of the notorious flying car? The roadable aircraft in development today leave us with hope… as well as something to be desired. Even the promising Moller Skycar falls short, lacking the ability to be driven as an automobile.

The self-driving, self-repairing, foam spewing car technology of Demolition Man is also unavailable to today’s motorist. When compared to the domestic conveniences afforded to us now, this film’s gorgeously grandiose vision of modern LA was the least in tune view of the future reviewed (we’ve got at least a couple of decades before 2032 to fix that, but we’d better get cracking).

Personally, I’ll be happy with a simple populuxe revival.

The categories in the chart should be pretty self-explanatory. But here's some explanation anyway:

We love our heroes to be super rich, and to have an excuse for self-pity. If your fabulously wealthy parents got killed in front of you when you're a kid, so much the better. (Seriously, a tragic past seems to be a crucial ingredient for many escapist heroes, because it lets you project all your own real-life pain onto your hero, even as you're imagining rising about that pain and becoming a mega-adventurer. )

And it makes us happy when our heroes have two or more devoted acolytes/sidekicks, who follow almost without question, and awesome gadgets. Superhuman powers means what it says. "Gets laid" doesn't just mean your hero hooked up one time.

"Marked for greatness" requires slightly more explanation. If your hero is the subject of a prophecy (like Starbuck), or is "the One" like Neo, then he/she is marked for greatness. Captain Kirk wasn't marked for greatness on the original Star Trek TV show, but we have a strong suspicion that the new Trek movie, by revisiting his origins, will show that he was marked for great things from the beginning.

"Not tied down" doesn't just mean being single: it means that you get to roam around having adventures. And at the end of an adventure, you jump in your spaceship and zoom off to the next adventure somewhere else. Captain Kirk wasn't tied down, but Captain Sisko was.

"Becomes a god or king" means your character ends up with a lot of people looking up to him/her. The Hulk, for example, is destined either to become a ruler, the Maestro, or the last survivor of Earth. Captain Kirk becomes an admiral, but more importantly he becomes a legend in his own time. The Doctor becomes the last of the Time Lords, and gets called a god a lot. Neo turns into the blind buddha Jesus monster, or something.

First, two caveats: most of these satellites are representative of an entire class of satellites. There may be others that serve similar functions, but the satellites listed are exemplars. Also, the list is obviously U.S.-centric. If you live in Europe or Asia, there are likely different satellites that fill the roles of these all-star orbiters.

Hubble Space Telescope - By taking thousands of breathtaking photos unhindered by the blurring effects of Earth's atmosphere, the Hubble has brought the beauty and mystery of space to more people than any other observatory, not to mention the massive amount of scientific research accomplished with it.

Galaxy 14 - This communications relay carries digital TV signals for much of the east coast, including ESPN, Lifetime, Sci-Fi, CNN, A&E and my personal favorite, the History Channel.

GOES-12 - From its high-altitude geosynchronous orbit, GOES-12 keeps a constant watch on weather conditions in most of North America.

The Moon - Tides, werewolves, the Apollo Program: without our natural satellite, we'd have none of these things.

KH-13 - This U.S. spy satellite is so secret, even the name is probably wrong (the government started giving them random names after people caught onto to the KH numbering system). Who knows what black budget, cutting edge satellite intelligence gathering devices are capable of these days?

GPS IIR11 - The U.S. government's NAVSTAR program brought global positioning abilities first to the military, then to the general public. It takes a constellation of these things for the system to work, so IIR11 is just one cog among many. Without it, there'd be no geocaching!

GoldenEye - With the ability to fire an EM pulse that could have wiped out an entire nation's financial records, GoldenEye is typical of fictional satellites and representative of our fears of orbiting weapons.

International Space Station - It's a symbol of international cooperation and a frontier outpost in the quest to colonize space. The low orbit maintained by the ISS makes it one of the easiest satellites to spot with the naked eye.

NOAA 17 - Unlike the GOES satellites, the NOAA satellites have asynchronous orbits, spinning around the globe to spot developing weather patterns that affect billions of people.

LANDSAT 7 - NASA and the U.S. Geological Survey teamed up in the 1970s to create a catalogue of Earth images shot from space. Since then, not only has the data improved with huge advances in digital photography, but numerous companies (including Google) have licensed the images for their mapping software.

Crowning a moon champion ain't as easy as it seems when Saturn alone has 59 of them. Fortunately the field got smaller when we considered five key points all moons should have on their resumes. It may be hard to stomach having Charon up there — it's questionable that it's even a moon — but someone had to be the goat.

And now, the winners in the individual categories:

BEST FEATURE NAME: Despite tons of creative feature names, Europa wins by a wide margin with Rathmore Chaos. It sounds like a level of Hell from Dante's Inferno, but like most of the outer system, the Chaos is a cold place. In fact it's a jumble of broken up ice that's evidence of the moon's active ice tectonics...and maybe a liquid water ocean below.

POTENTIAL FOR COLONIZATION: Phobos gave Earth's Luna a run for it's money; it's low gravity and proximity to the Red Planet make it worthy of it's full score. But in the end the deck's stacked against the Martian moon — the stated goal for NASA's next generation of manned spaceflight is to return to the moon...to stay.

ACTIVE GEOLOGY: This is a toughy. Uranus' moon Miranda doesn't have active geology, but scientists speculate that the whole moon may have been obliterated by impacts, then reassembled itself. You know, like T-1000 in Terminator 2. Charon, Triton, and Enceladus all look like they've got actively erupting cryovolcanoes of frigid ammonia, water, or liquid nitrogen which is cool, but it knocks Titan down a notch in uniqueness. Jupiter's Io wins for it's self sacrifice though; riddled with volcanoes, the firey moon is literally gutting itself, spewing 1 ton of sulfur dioxide into space every second.

MOVIE/BOOK: The hands-down winner is Earth's Moon, which has been in books and movies since the art forms were invented. It's hardly a fair fight, so the prize goes to Jupiter's Ganymede. The largest moon in the solar system (that's right, bigger than Titan!), it haunts tons of Philip K. Dick's books.

POTENTIAL FOR LIFE: Cryovolcanoes are going off all over the solar system's icy moons, and where there are volcanoes, there's liquid. Most of the liquid is in the form of methane, ammonia, nitrogen, or some other substance that Earth-life wouldn't want to swim in, but who knows what sort of strange aliens could be out there?

That said, Europa's icy shell is made of old-fashioned H2O, and features like Rathmore Chaos look a lot like shifting pack ice here on Earth, which floats on a big ocean of salty water, which in turn contains tons of critters. There's a good chance the same is true on Europa, meaning....

the prize for THE OVERALL AWESOMEST MOON IN THE SOLAR SYSTEM goes to EUROPA!!! Honorable mention to TItan for a strong showing, but it just goes to show...don't mess with the moon with the water oceans under the ice!

Let's go through some of the insights this chart offers.

ATOMICS/DEADLY ATTACKS: As you can see, there is a very clear historical connection between atomic bombs and atomic testing and giant monster movies, so that truism turns out to be correct. After a long period of no giant monsters in pop culture at all, we get a sudden burst of giant monsters in the 50s, many of which are explicitly created by "atomic tests" (see: the ants in Them, the dinosaur in Behemoth, Godzilla, and more). What's interesting is that there appears to be about a 10-year lag between the disaster and the first movies dealing with it. A similar lag happens between disasters of the 1990s and early 2000s and the giant monster explosion of the 00s. Interestingly, the biggest explosion in giant monster movies since the 1950s is going on in the 00s, perhaps as a response to global terrorism and human-caused disasters (see below).

PLAGUES: "Call of Cthulhu," which is about a giant monster who haunts people's dreams and drives them mad, could probably be linked to the "sleepy sickness" plague that was sweeping the United States at the time Lovecraft first thought up his tentacly menace. The disease made people appear to sleep all the time, and did drive them insane. But generally, as we can see later in the timeline, plague doesn't appear to spawn giant monsters. In fact, the HIV/AIDS plague has probably resulted in more human-sized monster tales: witness the explosion in vampire and zombie stories during the 1990s and 00s. So, generally, plague disasters don't cause giant monster movies.

NATURAL DISASTERS: One of the biggest natural disasters of the 20th century, the Yellow River floods in China in the 1930s, gave us no giant monsters. King Kong, the most popular giant monster of the 1930s, was probably inspired by Westerners "discovering" gorillas in Africa in the early 20th century. But the Indian Ocean earthquake and tsunami seems to have had an effect: two of the biggest giant monster movies of the last year have both involved beasts from the ocean.

HUMAN-CAUSED DISASTERS: Yes, human toxic spills and pollution seem to trigger giant monster movies. Most of the giant monsters in the 1970s and 80s are related somehow to pollution, and come soon after several widely-publicized oil spill disasters. Note that the 70s and 80s were also a time of human-sized toxic creatures, like the Toxic Avenger, the bears in Prophesy, the whatevers in CHUD, and so on. So these disasters inspire both giant and regular-sized monsters. I think the explosion in 00s monster movies may also be a result of the same lag we saw between atomics in the 1940s, and giant monsters in the 1950s. A lot of toxic disasters happened in the 80s and 90s, and suddenly a bunch of giant monsters pop up in the 00s.

What we found: As you might imagine, the real surge in literary novels with science fiction themes came in the past five or six years, after literary journal Conjunctions published its "New Wave Fabulist" issue and magical realism was on the wane. There were literary novels with SF themes, like David Foster Wallace's Infinite Jest, which didn't really fit into the general subject areas of "alternate history," "time warp," or "post-apocalyptic." We were most interested in seeing which years featured the most literary novels featuring those themes.

Of those three subcategories, alternate history was the most consistent, with literary authors using it to explore how wars could have gone differently, but also other topics. Not surprisingly, you saw more alternate history novels at the start of this period, when the U.S. was active in Somalia and still bombing Iraq, and then at the end, when we had invaded Iraq. Alternate history is traditionally a fairly conservative genre, with authors like Newt Gingrich dabbling in it and exploring how things could have turned out worse if we hadn't stiffened our spines. But a recent spate of alt-history novels is more liberal, exploring a world where the Aztecs never fell (Atomik Aztex) and a world where the Jews got a homeland in Alaska and we avoided the Middle East conflict (Yiddish Policemen's Union).

There was a boomlet in time-travel fiction, and stories about time acting strange, in 2003-2004, with Audrey Niffenegger's The Time Traveler's Wife proving a huge mainstream hit. This was the peak of the Bush-era resurgence in conservativism, with a lot of mainstream nostalgia about World War II and the Greatest Generation.

And then was a boom in post-apocalyptic fiction in more recent years, with three huge classics of the genre hitting in 2006. In particular, Cormac McCarthy's The Road has become the poster-child for the literary-authors-going-speculative trend. These books coincided with the Indian Ocean Tsunami, Hurricane Katrina, and a worsening Iraq conflict. But there's been a lull in the post-apocalyptic genre since then as well.

Cylons have thinned an interplanetary civilization down to 50 thousand members, and as season four begins the humans have been reduced to roughly 41 thousand. We even know roughly how many days it's been since the first Cylon attack. In our chart, we've correlated each population change with an event, including when each new Cylon is revealed.

All this information comes directly from the show, where most episodes begin with a population number. Numbers are also frequently bandied about in trials and policy debates. Many of these numbers were faithfully recorded, in great detail, by the amazing folks behind the Battlestar wiki. Is this emphasis on hard numbers a reflection of the U.S. obsession with numbers of dead in Iraq, or is it just part of a general trend toward realism in science fiction?

As you can see, Trek's crews have always treated the Prime Directive like a speed limit on the Interstate. But the high point of Prime Directive violations was the late 1990s, which surpassed even the late 1960s of Kirk's cowboy-ism.

At the same time, the United States was reducing its troop presence around the world. Why did Starfleet start interfering more, even as America was throwing less of its weight around? The late 1990s was an era of military spending cutbacks and base closures, when the U.S. seemed to be less influential without the threat of the Soviet Union to rally our own citizens, let alone our allies.

I know what you're going to say: It's all down to Star Trek: Voyager's Captain Janeway and her "anything goes" approach. But first of all, Janeway's not the only culprit. Ben Sisko on Deep Space Nine also played fast and loose with the Directive more in the late 1990s than in its earlier seasons. And the Federation also threw its non-interference principles out the window, in different ways, in both 1998's Star Trek: Insurrection and 2002's Star Trek: Nemesis.

But also, consider that Voyager is a metaphor for the U.S.' more confusing situation after the Cold War. Instead of being one superpower facing another (like the Klingons, Romulan or Borg) suddenly the Voyager is isolated in a quadrant full of independent players, each of whom has its own agenda. Just as the Soviets were replaced with Bosnians, Serbs and Kosovans and the U.S. had to form alliances to deal with messy situations, Voyager faces a bunch of warring races and Janeway has to strike deals with different races to escape in one piece.

All of which makes us wonder: If Star Trek were on the air as a television show now, and it took place during an era where the Directive applied, would we see fewer violations? After all, U.S. troop levels in other countries have rebounded, and we're once again involved in a massive confrontation overseas. Would a 24th century Trek step more lightly around the galaxy, to counterbalance the United States' greater use of force?

Here is our Martian woman's spec:

First, our woman is tall, a little pear-shaped, with really thick legs. This shape compensates for the reduced gravity.

She has a very lightweight exoskeleton covering her whole body. The exoskeleton has to keep her warm, keep her pressurized, shield her from solar wind, and absorb lots of sunlight. So it can be thin, but laced with heated mesh. It should have a nanofabric outer shell laced with lead to repel x-rays and other cosmic rays. And the upper half should have super bendy, ultra-thin solar cells that are constantly sucking up solar energy.

In her boots and strapped to her thighs, she has water drilling/processing packs. A cannulated drill can extend out of it, go deep under martian crust, suck up water, run it through a filter to get the salt and acid out, and then store it close to her body to keep it liquid so she can sip from it.

She also has a photosynthesis rig on her back. This is a light, thin backpack that converts the C02 from the atmosphere and some of the water from her leg pack into sugars and oxygen for our Martian. So it's a combination breathing apparatus and feeder.

To some extent, it's understandable that space adventures play fast and loose with physics. After all, who wants to watch Han Solo spend years on the journey to Alderaan, only to find that the planet has twice Earth gravity and he can barely stand up, much less swagger?

The categories of mistakes in our report card should be pretty self-explanatory, but just in case, I'll expand on them a little bit:

• There's no sound in space
• Not all planets have Earth gravity
• Planets should have diverse climates, instead of one unified climate across a "desert planet" or "forest planet."
• It shouldn't be too easy to communicate with alien creatures, without some kind of high-technology "translator" explanation.
• And it definitely shouldn't be too easy for humans to interbreed with aliens.
• Humans exposed to vacuum without a spacesuit shouldn't explode or shatter. And a "hull breach" where the ship's crew is exposed to vacuum should kill everyone instantly.
• You can't have fires in space, unless there's oxygen leaking out somehow.
• Asteroids or other objects shouldn't be able to float close together without falling into each other's gravity
• People shouldn't be able to dodge lasers and other speed-of-light weapons
• And there's no reason why someone would move in slow-motion in zero gravity.
• Faster-than-light travel is probably not ever going to be possible.
