This is part of IEEE Spectrum’s Special Report: Why Mars? Why Now?
Let’s get this up front: The best Mars movie is Paul Verhoeven’s Total Recall. The 1990 sci-fi thriller stars Arnold Schwarzenegger as a former counterrevolutionary who’s had his memory erased and is trying to figure out who he is and who his enemies are on a Mars wracked by revolution. Like all of Verhoeven’s movies, it is compulsively watchable and has creative if often gratuitous violence and sleaze—and also Verhoeven’s obligatory femme fatale, in this case played by Sharon Stone.
The film explores issues of identity, as in this exchange between Schwarzenegger’s character and Stone’s, just after they’ve tried to kill each other:
Schwarzenegger: “If I’m not me, who the hell am I?”
Stone: “Beats me. I just work here.”
Sure, the movie’s good. But is it really the best movie ever made about Mars?
Consider the competition. And when doing so, be sensible and define a movie about Mars as one in which at least part of the plot takes place on Mars. Dozens of movies meet that criterion, but dozens more with the word Mars in their title do not. Of the ones that do, maybe five or six at most are worth watching. Yep, a century of Mars movies and you have barely enough for a one-day film fest (see the accompanying tables of ”Favorite Mars Movies” at the end of this article).
It’s puzzling. Mars has fascinated Earthlings for millennia, ever since sages saw the pink dot in the night sky and wondered why it wandered. The ancient Greeks, seeing red and thinking blood, named it after their god of war, Ares; later the Romans just substituted the name of theirs: Mars. The body of literature about Mars is rich [see “Kim Stanley Robinson’s 10 Favorite Mars Novels”], and a reasonable portion of it is intellectually stimulating.
The movies, not so much. One of the earliest was A Trip to Mars, a 4-minute kinetoscope produced in 1910 by one of Thomas Edison’s movie companies. A magical powder enables a professor to float to Mars, where he is attacked by aggressive trees and tumbles onto the lip of a giant Martian creature. It can’t be called an auspicious beginning.
In the decades that followed, motion-picture directors used Mars and Mars voyages as a backdrop for adventures that could have been set just about anywhere, and also as a contrivance to develop themes that would resonate. That’s what directors do, after all. In postrevolutionary Russia, for example, a visit to Mars depicted in the film Aelita: Queen of Mars (1924) became an occasion to demonize capitalism and glorify bolshevism.
In the United States, where the vast majority of these movies have been made, Mars changed with the times. In the 1930s, it was an alternative to the American West in cheesy serials featuring sets more exotic than cowpoke towns, and villains more exotic than unshaven men in black hats.

An exception is Just Imagine, one of the oddest films of cinema’s adolescence, the brief transition between silent films and talkies, precode and postcode. Released in 1930, Just Imagine is a talkie, but it has intertitles, like a silent movie. The plot is wispy: A young man needs to impress government officials to marry the woman he loves. So he goes to Mars with his best friend and, it turns out, a stowaway who seems to have wandered into the movie from a vaudeville show. Upon arriving, the three immediately encounter Martians, who seem to differ hardly at all from Earthlings. The female Martians, in big hair and shiny two-piece bathing suits, seem to be what on Earth 25 years later will be called Vegas showgirls. The acting is terrible and the dialogue is unbearable at times. But the art deco sets, [see our accompanying slide show, “Mars Movies: The Good, The Bad, The Ridiculous”] effects, and costumes are all stunning for their era.
Mars then basically disappears from cinema for about two decades, reappearing in the golden age of sci-fi motion pictures, the 1950s. The best of those sci-fi films are either paranoid fever dreams inspired by Cold War dread ( Invasion of the Body Snatchers, It Came From Outer Space), or they’re moralistic melodramas tinged by an infatuation with technology and/or a vague sense of wonder at the cosmos (Forbidden Planet, The Day the Earth Stood Still). Unfortunately, none of the Mars movies of the 1950s fit into either category.
Flight To Mars (1951) was shot in five days using borrowed costumes, sets, and even sounds. “Cameron Mitchell, who stars in it, barely remembers it,” says Gerry Williams, who maintains The Mars Movie Guide and organizes the Mars Society San Diego chapter’s monthly Mars movie nights. Flight follows the standard trajectory: Earth ship with attractive coed crew lands on Mars and finds a civilization with people who look exactly like Earthlings and even speak English. But beneath their padded tunics, these Martians harbor Earth-invasion plans, because their world is dying.
Much of the plot and dialogue is so ridiculous that the film is surprisingly enjoyable today as an unintentional parody of ’50s sci-fi pictures. The movie has precisely one clever touch: The Martian heroine is named Alita, an apparent homage to the Russian movie’s Queen Aelita.
Invaders From Mars (1953), a compelling piece of Cold War paranoia rendered cleverly in primary colors, doesn’t really have anything to do with Mars. The Martians might as well be Venusians. Ditto Red Planet Mars (1952), a story about rival Cold War radio engineers, one of whom makes contact with a Martian civilization. It starts promisingly but degenerates abruptly into inanity when viewers are asked to accept that God has chosen Mars from among the universe’s many celestial bodies to be His base from which to proselytize by radio. At least the inanity is revealing: “It’s mind-boggling from a cultural perspective,” notes Vivian Sobchack, a former associate dean of the film school at the University of California, Los Angeles and author of Screening Space: The American Science Fiction Film (Rutgers University Press). Time.com recommends the movie “as a rear-view mirror into the roiling national psyche of the ’50s” U.S.A.
In the early 1960s, the surging U.S. space program rejuvenated interest in Mars and helped spawn two striking yet meandering exercises, each based on a well-known fable. Robinson Crusoe on Mars (1964) and The Wizard of Mars (1965) are interesting partly because they were the last gasp, so to speak, of the cinematic Mars where people could walk around in light clothing, breathe through compact thingamabobs, and happen upon complex life.
Crusoe, in particular, is still very fondly regarded by cinephiles. “It uses the landscape as something more than a setting for chases,” says Sobchack. “It’s about survival. A use of the landscape as this strange and hostile place. It’s beautiful.”
In July 1965, the U.S. space probe Mariner 4 flew by Mars and began sending back the first close-up pictures of the planet. They showed a cratered world that was airless, waterless, canal-less, and devoid of the sort of life that could green-light a script.
From that point onward, strolling around on Mars in street clothes became a no-no. Also out: Martians that seem distinguishable from humans only in their more-daring fashion choices.
Mars movies pretty much disappear again for the next 25 years, except for a few cinematic curiosities and a couple of TV series. The unintentionally funny 1967 throwback, Mars Needs Women, is about a dying race that needs nubile Earthlings with whom to breed.
In 1976, the U.S. Viking landers do their thing, and interest in Mars resurges hugely. But not a single decent Mars movie comes out of it. In fact, Viking’s sharp images of beautiful, barren Martian plains probably did more harm than good, Sobchack says. After Viking, the fake Mars images of cinema lost much of their power to captivate. Or even to be taken seriously. “There was this feeling that, ‘Okay, we’ve seen it. So?’ ”
To sum up: no agreeable environment; no plausible indigenous antagonists. “So now what?” asks Sobchack. “If you go there with your script, what do you do? There seem to be two choices: some sort of a chase, or you have your crew killing each other off for various reasons.”
In the 1970s, writers and directors of serious science-fiction films weren’t much inclined to do either. They were too busy grappling with earthly social issues in high-concept movies like Soylent Green, Logan’s Run, Silent Running, and A Clockwork Orange. The only notable motion picture with any connection to Mars is Capricorn One (1978), a post-Watergate conspiracy-theory vehicle centered around U.S. officials faking a trip to Mars to avoid national embarrassment. Nobody goes to Mars. In fact, that’s the point.
Eventually, six more Mars movies come along: Total Recall in 1990, Escape From Mars in 1999, Red Planet and Mission to Mars in 2000, John Carpenter’s Ghosts of Mars in 2001, and Stranded in 2002.
In this, the most recent cycle of movies, the pseudoscientific backdrop is terraforming, the theory that humankind could change, radically and globally, the environment of a planet in a short period of time. It shouldn’t seem too implausible if, say, you liked Al Gore’s movie. In Ghosts of Mars, terraforming is just a piece of backstory that lets the actors, notably former supermodel Natasha Henstridge, run around on Mars in tight sweaters (that is, we’re back to the 1950s again). But terraforming is an integral part of the plot, albeit a contrived one, in Total Recall, Red Planet, and Stranded. Whether the whole terraforming thing has any more cinematic life in it is now moot.
Today, seven years since the last significant Mars movie, there are a couple more of them in the works. John Carter of Mars, a version of Edgar Rice Burroughs’s 1917 novel A Princess of Mars, is scheduled for release by Walt Disney Pictures in 2012. It is to be directed by Andrew Stanton Jr. (Finding Nemo, Wall-E ), so it will probably be entertaining, at least. But given the source material, it will almost certainly be a fantasy vehicle rather than sci-fi. Disney is also reported to be working on an animated movie for children based on the Berke Breathed book Mars Needs Moms. It’s difficult to imagine it being compelling for adults.
Sobchack would love to see a great Mars picture, but she isn’t, uh, holding her breath. “We live in a science-fictional culture, and it’s hard to come up with something truly strange or novel,” she says. In the science-fiction movies of the 1950s, she adds, “there was a fascination with the science itself that gives them a kind of gravitas. But nobody cares about that anymore.
“Plausibility has always been an issue in sci-fi,” she continues. Even in the best of the 1950s pictures, you could usually count on a scientist character at some point to spout “some gobbledygook that quite literally rationalized what was going on.
“But when you live in a science-fictional world, sci-fi is not going to knock your socks off,” she adds. “You want fantasy and comic-book movies in which you can put whatever you want to zing audiences. It’s called ‘wish fulfillment.’”
Seen in this light, the quest for the great Martian movie is up against two major obstacles, Sobchack explains. One is the general trouble with sci-fi movies set on a planet: the tendency for them to degenerate into chases or orgies of extraterrestrial homicide. The other obstacle is the general decline of movie sci-fi and its replacement by fantasy and comic-book movies.
Still, there are reasons to hope that a great Mars movie will get made some day. Start with this one: If NASA is serious about going to Mars, it’s hard to imagine it happening without the kind of mass public enthusiasm that movies are good at nurturing and even better at exploiting. Then, too, there’s that rich and untapped body of Mars literature.
The movies have been kind to Philip K. Dick— Total Recall, for example, was based on his short story ”We Can Remember It for You Wholesale”—but his best two works about Mars, Martian Time Slip and The Three Stigmata of Palmer Eldritch, have yet to get cinematic treatments. Time Slip, in particular, intrigues sci-fi scholars. “It would be a great movie about the ‘Other’ with a capital ‘O,’ ” says Jorge M. Martins Rosa, an assistant professor at the Universidade Nova de Lisboa, in Portugal. In Time Slip, “the Martians are just like primitive people, being subjugated by this corporation. It could explore issues of colonialism. It would be a fantastic movie, if properly done.”
Kim Stanley Robinson, whose trilogy on Mars is considered one of the best works ever about the planet, is the other novelist most frequently cited by wistful sci-fi cineastes. The cable channel AMC announced last October that it had begun working on a TV series based on Red Mars, the first novel in the trilogy. No release date has been set. From the same general period as Robinson’s books (the 1990s) came many other worthy novels, including ones by Greg Bear, Ben Bova, Paul J. McAuley, and Gregory Benford.
Maybe the best reason for hope is Mars’s clear appeal to something deep in us. Having emerged from our myths, it still feeds our fantasies. It’s the most interesting motif left in archetypal dreams of escape and adventure in strange, vast realms, of human rejuvenation and transcendence through exodus and hardship.
“A lot of it, for me, just comes from the idea of a group of people getting together and doing something incredible: building a spaceship to go to another planet,” says Williams, whose personal collection of Mars-related movies runs to 154 titles. “The actual going is the awesome part for me…and when they get there, that feeling that, ‘My God, we’ve made it to another world.’ ”
The Red Planet isn’t home to charismatic life. But maybe it will be when our descendants, having conquered it, discover that it has transformed them into something new.

Made in bulk for the first time, this new carbon allotrope is the semiconductor graphene isn't
Prachi Patel is a freelance journalist based in Pittsburgh. She writes about energy, biotechnology, materials science, nanotechnology, and computing.
Researchers have found a way to make graphyne, a long-theoreized carbon material, in bulk quantities. Like its cousin graphene, graphyne is a single layer of carbon atoms but arranged differently.
Since graphene’s discovery 18 years ago—leading to a Nobel Prize in Physics in 2010—the versatile material has been investigated for hundreds of applications. These include strong composite materials, high-capacity battery electrodes, transparent conductive coatings for displays and solar cells, supersmall and ultrafast transistors, and printable electronics.
While graphene is finding its way into sports equipment and car tires for its mechanical strength, though, its highly touted electronic applications have been slower to materialize. One reason is that bulk graphene is not a semiconductor. To make it semiconductive, which is crucial for transistors, it must be produced in the form of nanoribbons with the right dimensional ratios.
There’s another one-dimensional form of carbon related to graphene that scientists first predicted back in 1987, that is a semiconductor without needing to be cut into certain shapes and sizes. But this material, graphyne, has proven nearly impossible to make in more than microscopic quantities.
Now, researchers at the University of Colorado in Boulder have reported a method to produce graphyne in bulk. “By using our method we can make bulk powder samples,” says Wei Zhang, a professor of chemistry at University of Colorado Boulder. “We find multilayer sheets of graphyne made of 20 to 30 layers. We are pretty confident we can use different exfoliation methods to gather a few layers or even a single layer.”
Graphite, diamond, fullerenes, and graphene are all carbon allotropes, and their diverse properties arise from the combination and arrangement of multiple types of bonds between their carbon atoms. So while the 3D cubic lattice of carbon atoms in diamond make it exceptionally hard, graphene’s single layer of carbon atoms in a hexagonal lattice make it extremely conductive.
Graphyne is similar to graphene in that it’s an atom-thick sheet of carbon atoms. But instead of a hexagonal lattice, it can take on different structures of spaced-apart rings connected via triple bonds between carbon atoms.
The material’s unique conducting, semiconducting, and optical properties could make it even more exciting for electronic applications than graphene. Graphyne's intrinsic electron mobility could, in theory, be 50 percent higher than graphene. In some graphynes, electrons can be conducted only in one direction. And the material has other exciting properties such as ion mobility, which is important for battery electrodes.
Zhang, Yingjie Zhao of Qingdao University of Science and Technology, in China, and their colleagues made graphyne using a method called alkyne metathesis. This is a catalyst-triggered organic reaction in which chemical bonds between carbon atoms in hydrocarbon molecules can crack open and reform to reach a more stable structure.
The process is complicated and slow. But it produces enough graphyne for scientists to be able to study the material’s properties in depth and evaluate its uses for potential applications. “It will take at least a couple years to have some fundamental understanding of the material,” says Zhang. “Then it will be in good shape for people to take it to a higher level, which is targeting specific semiconducting or battery applications.”
He and his colleagues plan to investigate ways to produce the material in much larger quantities. Being able to use solution-based chemical reactions would be critical for making graphyne at industrially relevant scales, he says.
It’s just the beginning for graphyne though, and for now, just being able to make this long-hypothesized material in sufficient quantities is an exciting first step. “Fullerenes were discovered in the 1980s, then nanotubes in the early '90s, then graphene in 2004,” Zhang says. “From discovery of a new carbon allotrope to its intensive study to first application, the timeline is becoming shorter. I’m already receiving calls from venture capitalists around the world. But I tell them it’s a little bit early.”
It’s a lot of progress over just one year
One year ago, we wrote about some “high-tech” warehouse robots from Amazon that appeared to be anything but. It was confusing, honestly, to see not just hardware that looked dated but concepts about how robots should work in warehouses that seemed dated as well. Obviously we’d expected a company like Amazon to be at the forefront of developing robotic technology to make their fulfillment centers safer and more efficient. So it’s a bit of a relief that Amazon has just announced several new robotics projects that rely on sophisticated autonomy to do useful, valuable warehouse tasks.
The highlight of the announcement is Proteus, which is like one of Amazon’s Kiva shelf-transporting robots that’s smart enough (and safe enough) to transition from a highly structured environment to a moderately structured environment, an enormous challenge for any mobile robot.
I assume that moving these GoCarts around is a significant task within Amazon’s warehouse, because last year, one of the robots that Amazon introduced (and that we were most skeptical of) was designed to do exactly that. It was called Scooter, and it was this massive mobile system that required manual loading and could move only a few carts to the same place at the same time, which seemed like a super weird approach for Amazon, as I explained at the time:
From what I can make out from the limited information available, Proteus shows that Amazon is not, in fact,behind the curve with autonomous mobile robots (AMRs) and has actually been doing what makes sense all along, while for some reason occasionally showing us videos of other robots like Scooter and Bert in order to (I guess?) keep their actually useful platforms secret.
Anyway, Proteus looks to be a combination of one of Amazon’s newer Kiva mobile bases, along with the sensing and intelligence that allow AMRs to operate in semistructured warehouse environments alongside moderately trained humans. Its autonomy seems to be enabled by a combination of stereo-vision sensors and several planar lidars at the front and sides, a good combination for both safety and effective indoor localization in environments with a bunch of reliably static features.
I’m particularly impressed with the emphasis on human-robot interaction with Proteus, which often seems to be a secondary concern for robots designed for work in industry. The “eyes” are expressive in a minimalist sort of way, and while the front of the robot is very functional in appearance, the arrangement of the sensors and light bar also manages to give it a sort of endearingly serious face. That green light that the robot projects in front of itself also seems to be designed for human interaction—I haven’t seen any sensors that use light like that, but it seems like an effective way of letting a human know that the robot is active and moving. Overall, I think it’s cute, although very much not in a “let’s try to make this robot look cute” way, which is good.
What we’re not seeing with Proteus is all of the software infrastructure required to make it work effectively. Don’t get me wrong—making this hardware cost effective and reliable enough that Amazon can scale to however many robots it wants to scale to (likely a frighteningly large number) is a huge achievement. But there’s also all that fleet-management stuff that gets much more complicated once you have robots autonomously moving things around an active warehouse full of fragile humans who need to be both collaborated with and avoided.
Proteus is certainly the star of the show here, but Amazon did also introduce a couple of new robotic systems. One is Cardinal:
There’s also a new system for transferring pods from containers to adorable little container-hauling robots, designed to minimize the number of times that humans have to reach up or down or sideways:
It’s amazing to look at this kind of thing and realize the amount of effort that Amazon is putting in to maximize the efficiency of absolutely everything surrounding the (so far) very hard-to-replace humans in their fulfillment centers. There’s still nothing that can do a better job than our combination of eyes, brains, and hands when it comes to rapidly and reliably picking random things out of things and putting them into other things, but the sooner Amazon can solve that problem, the sooner the humans that those eyes and brains and hands belong to will be able to direct their attention to more creative and fulfilling tasks. Or that’s the idea, anyway.
Amazon says it expects Proteus to start off moving carts around in specific areas, with the hope that it’ll eventually automate cart movements in its warehouses as much as possible. And Cardinal is still in prototype form, but Amazon hopes that it’ll be deployed in fulfillment centers by next year.
Think back to when you were a young and an eager beginner in technology. Remember the first time you took apart your first PC, wrote your first line of code, learned how to hack Doom. The easiest way to learn technology was (and is) by being hands-on.
“Hands-on learning is 15X more effective than passive learning (ie. lectures).”
Getting started in technology can be intimidating. If you want to learn technology these days, there aren’t many great options.
Since these are purely digital, you don’t get the hands-on experience of building electronics. These often end up being just coding lessons.
Most schools don’t even offer electronics and programming in their curriculum. Even fewer engage students in hands-on learning. If you’re lucky, you might find a school that has an afterschool program led by a passionate STEM educator.
“There are nearly 500,000 open Computing jobs in the U.S. alone.”
You can find some hands-on projects that use block code and snap-on parts, but these are often oversimplified to the point that you don’t even learn the fundamentals. When you remove the potential of making mistakes, you lose the connection to how things work in the real world.
What happened to the good ole days of getting your hands dirty with real hardware and programming?
The truth is, people learn best by doing.
That’s why we created Creation Crate, a tech subscription box that prepares learners for the jobs of the future by teaching them how to build awesome DIY electronic projects!
Would you rather build your own bluetooth speaker, or read a textbook on electronics? Hands-on learning is not only more engaging, but fun too. Learning shouldn’t be a chore, and Creation Crate makes sure of that.
Creation Crate combines hands-on learning with educational electronics courses to teach electronics, circuits, coding, critical thinking, problem solving, and more!
“I am majoring in STEM (physics and computer science double-major), and I ordered this mainly for the purpose of tinkering and expanding my computer engineering knowledge through independent projects, and even for me, this bundle ended up being incredibly handy and interesting. Thank you guys, and good luck in the future!” - Roman F.
If there was ever a time to be an aspiring engineer, it’s now! The cost of components is a fraction of what it was ten years ago. Anyone can get access to the hardware and software used in everyday tech careers.
So why settle for anything but the real thing?
With Creation Crate, everything necessary is delivered in a kit to your door. Kits include all the components needed to build your project. You will also find access to an online classroom with detailed step-by-step video tutorials.
Each project uses an Uno R3 (Arduino-compatible) Microcontroller, a small programmable computer that acts as the brain of the project.
They’ll also learn how to use components like a Breadboard, Ultrasonic Sensor, LED Matrix, 7-Segment Display, Accelerometer, Distance, Pressure, Temperature, & Humidity Sensors, LCD Screen, Keypad, Microphone Module, Resistors, Servo Motors, Motor Driver Board, and more!
Learning how to program is a tedious but rewarding process. Most engineering careers in technology require an understanding of programming languages like Java, C++, Python, Ruby, and others.
With Creation Crate, students will learn how to write their own computer programs in the Arduino language (C/C++) to make their projects come to life!
Each project will introduce different lessons in programming C++. Here are a few examples of what they’ll learn:
What are Comments and Variables?
As your aspiring engineer progresses through the curriculum, they’ll learn how to build and program electronic projects that become more challenging as they learn new lessons. They’ll learn how to build things like...
A color-changing mood lamp that activates when the lights are off
An optical theremin that let you create music simply by waving your hands
A Bluetooth speaker that plays music from your phone
A rover bot that avoids obstacles and follows lines
By the end of the curriculum, they’ll have more hands-on learning experience in hardware and programming than many students receive in a four year degree!
“Creation Crate fills a void that has existed in the Tech Subscription box world. Most kits are aimed at the very young or adults with extra income. Creation Crate is affordable and challenges tweens and teens (and at least one adult!). I especially appreciate the manner in which the project challenges build from month to month.” - Justin D.
Family activities create everlasting memories. The key to a great family activity is to do something that everyone enjoys and is interested in.
Unlike every other “learn electronics kit” out there, this isn’t just for kids and teens. Even adults will find the projects fun and challenging! That’s why Creation Crate makes the perfect family activity for parents looking to spend more quality time with their child.
“By high school, a child will have used up 90% of in-person parent time” - Tim Urban (Author Wait But Why)
Americans spend almost $13 billion on unwanted presents each year. Why not gift something that’s not only fun, but will help develop a lifelong skill?
