This morning, io9 demonstrated that in addition to putting out an awe-inspiring blog every day, they could also put on a mind-expanding Comic Con panel.  With no Hollywood celebrities and just a couple of special guests, our favorite sci-fi bloggers ran through the TV shows, movies, comics and books of the past year that “blew our minds without blowing up any giant robots.”

Here are a few of their recommendations:

Moon -Duncan Jones’s new movie topped the list for both Annalee Newitz and Meredith Woerner.  Like a lot of the works recommended by the panel, Moon explores what it means to be human in a rapidly approaching era where humanity can be technologically upgraded or artificially created (note: this is not a spoiler, the lead character realizes very early in the film that he is a clone).

Julian Comstock – In this novel, Robert Charles Wilson depicts a 22nd century American that has sunk into barbarism and theocracy.  In response, the hero undermines the regime in part through trying to popularize ideas about Darwin in a world that has forgotten about science.

Rest -  What if someone invented a pill that meant no one would ever have to sleep, with no adverse side effects?  Panel guest Bonnie Burton from StarWars.com picked the Devil’s Due comic Rest, which explores this idea and its implications on society, the environment and mental health.

Wonton Soup – James Stokoe’s comic, recommended by Graeme McMillan, investigates what humans would do if they had to be out in space for a really long time.  Apparently the answers are get high and cook alien recipes.

Infoquake – io9 editor Charlie Jane Anders picked a series of novels by David Louis Edelman.   In Edelman’s future, people can hack and upgrade their own bodies and brains, impacting human relations in both the literal and business senses of the phrase.

Forty years ago today, Neil Armstrong made science-fiction geeks out of everyone. Without waxing too poetic, it was the moment when decades—if not centuries—of dreams about going to new worlds became a reality. With all due respect to Yuri Gagarin and Alan Shepard, Armstrong’s step onto an actual extraterrestrial surface was the first real space travel, in the sense of going somewhere. For a short while, there actually was a man on the moon.

Given the awesomeness of science non-fiction that year, I might almost expect it to be a down year for science fiction. Not so. 1969 had some good sci-fi—maybe not as good as landing on the moon, but damn good nonetheless.

It was, for example, the year Billy Pilgrim came unstuck in time. In Slaughterhouse-Five, Kurt Vonnegut challenged the idea that sci-fi wasn’t an appropriate genre for high-brow “literary-fiction” writers, tradition that has carried forward to become the “counter factual” fiction (sci-fi by any other name…) of writers like Margaret Atwood and Michael Chabon. It was also the year Ursula K. LeGuin explored gender and identity in Left Hand of Darkness, and Michael Crichton scared the bejesus out of everyone with his  mutated virus in The Andromeda Strain. Ray Bradbury published a collection of short stories in I Sing the Body Electric (the title story of which became The Electric Grandmother), and Isaac Asimov collected some of his best stories in Nightfall and other Stories.

Maybe it’s because nanoFET sounds like Boba Fett, but the name just screams “science fiction” to me. The device is still in very early stages of development, but it could theoretically propel spaceships into the vicinity of light speed. And getting close to light speed means going to other solar systems, and THAT means a science fiction-like reality. So work with me here.

If a nanoparticle field emission thruster (the aforementioned NanoFET) has been a subject of investigation for University of Michigan electrical engineer Brian Gilchrist for several years now. Gilchrist, joined by a team of scientists, has published and presented papers (pdf) at conferences (pdf) around the country, trying to show the theory of how electronically charged nanotubes could enable a spaceship to achieve astonishing speeds.

Today we present a very special installment of the Codex Futurius, Science Not Fiction’s look at the big scientific ideas in sci-fi: Kevin Grazier—JPL physicist and friend of SNF—gives an insider’s peek at the workings of and discussion around the Orion antimatter drive used to propel the Phaeton starship in Ron D. Moore’s recent TV movie, Virtuality. Grazier was a science adviser for the movie (which was intended to be the pilot for an ongoing show), so he was right in the middle of these discussions. The screenshot further down in this post shows the actual spreadsheet used in the production to see what stars would be reachable with the Orion drive. Without further ado, here’s some sci in your sci-fi:

DISCOVER: What kind of realistic technology could we use to get to nearby stars? Which stars would be feasibly reachable by such technologies?

Kevin Grazier: It’s a saying plastered on T-shirts and bumper stickers—the kind sold at both science-fiction conventions and physics departments nationwide:

186,000 miles per second:
It’s not just a good idea, it’s the law.

The speed of light, of all electromagnetic energy, in a vacuum is the ultimate speed limit in the universe. Nothing that has mass or carries information can travel faster.

This universal speed limit is a direct fallout from Albert Einstein’s special theory of relativity. Special relativity implies that the speed of light in a vacuum is a universal constant, but values that we tend to think of as constant in our daily experience—mass, length, and the rate of the passage of time—are not. Depending upon the relative velocity of two observers, these values will “adjust” so that both observers see the speed of light as a constant. Two observers travelling at high speeds relative to each other will find themselves in strong disagreement about measurements like the length of each other’s spacecraft and the rate of the passage of time.

Another consequence of special relativity is that, as an object travels increasingly faster, it behaves as if it has increasingly more mass. Therefore the amount of thrust it takes for an incremental change in velocity (known in the space program as a delta-V) is vastly greater at high speeds than at low. This effect is also highly nonlinear: It takes almost an order of magnitude more thrust to accelerate from .9c (nine-tenths of the speed of light) to .99c than it does to accelerate from .5c to .7c. An object travelling at the speed of light would act as if it had an infinite amount of mass and it would, therefore, require an infinite amount of energy (read: an infinite amount of thrust/fuel) to attain it.

This is, of course, a shame for civilizations (like ours) who want to explore planetary systems around other stars first hand. The distances involved are, well, astronomical. Just within the Solar System, it typically takes NASA probes 6 months to a year to reach Mars; it took Cassini 6 years, 9 months to reach Saturn. The (currently) fastest object created by humankind, the Voyager 1 spacecraft, will take 40,000 years, give or take a few thousand years, before it makes its closest encounter with its first star: AC+79 3888—currently located in the constellation Ursa Minor. At that speed few Time Lords, and even fewer humans, would survive the journey to even “nearby” star systems.

In memory of Karl Malden, who passed away last week at the age of 97, Hero Complex digs up this trailer for 1979′s “Meteor“, one of “the last and least regarded films from the 1970′s disaster genre.”

So, without further ado, here is what it would have looked like if a large object hit the Earth, during the 70′s, and many, many movie stars from that era (including Malden, Sean Connery, Natalie Wood, Brian Keith from Family Affair and a presidential Henry Fonda) had to run around reacting to it.

Stand back, humanoid! Here comes the next installment of the Codex Futurius project, this blog’s never-ending quest to explore the ineffable scientific ideas raised by science fiction. This question on killer asteroids goes to Kevin Marvel, head of the American Astronomical Society. Thanks to Dr. Marvel for the scary info and to Jennifer Ouellette, the director the NAS’ Science and Entertainment Exchange (SEEx) program, for connecting us with him.

Question: How big an asteroid would be needed to completely destroy a planet?
That’s easy. It would have to be really, really big or moving very, very fast (or both for a real whopper of an impact), but there are some subtleties that are worth explaining.

First off, let’s admit that we’re really concerned with how big an asteroid would destroy planet Earth, especially life on Earth. I’m a bit more worried about my home planet than Mars, Jupiter, or even Pluto and even more worried about all the life we see around us (not to mention ourselves!). Earth is far more important from the human perspective, so let’s tackle that question.

Frighteningly, many large objects have hit Earth. Real whoppers. That’s a bit scary to think about. The good news is that the Earth is still here, so apparently large impacts of the planet-destruction kind rarely happen. We do know that smaller impacts have happened, such as the meteorite that hit the high Arizona desert just east of Flagstaff, at the site known as Meteor Crater. If we could count the impacts, we could gauge how frequently and when the impacts took place.

In our vigilant monitoring of the popular media for all things science-related, we’ve identified an emerging trend: scientists as fashion accessories.  In just the last few weeks both GQ and Louis Vuitton have inserted scientists and/or astronauts into glossy fashion shoots.

The GQ layout, “The Rock Stars of Science,” introduces a public service campaign that matches musicians with leading researchers in different medical fields to highlight the need for additional research funding.  The featured scientists include Francis Collins,  Harold Varmus and Anthony Fauci, all of whom have been mentioned in DISCOVER recently, so we can’t quarrel with the science cast or the cause.

My beef is with the rock stars.  Joe Perry?  Sheryl Crow?  Seal?  It’ s beyond me why GQ couldn’t find anyone who had produced a meaningful hit in the last ten years.  How about Tunde Adebimpe from TV on the Radio (bonus: album is called “Dear Science“)?

Even on the harsh deserts of Arrakis, the the water recycling capacity of a stillsuit prevent the wearer from would only lose a thimbleful  of water a day.  If you figure a thimble holds about 10 milliliters of water, and an astronaut normally consumes 2.7 liters of water per day through eating and drinking, that’s only a loss of .4% of the body’s daily water. Pretty impressive for a desert race with long life but limited resources. (In case this wasn’t clear, I’m talking about George Frank Herbert’s Dune here.)

Until recently, there was no need for us to try and engage with this sort of water recycling technology. In general, water has been plentiful in this world, and if it wasn’t we just piped it in. (I just re-saw Chinatown, so I’m feeling up on all this.) But increasingly short supplies of water in the American southwest and elsewhere have turned eyes to water recyling as at least a part of the long-term water supply solution. But to take a more extreme situation, let’s look at the final frontier, where there’s really no water at all. In fact, to transport water up to the International Space Station costs $15,000 a pint if we let the Russians do it, more if we send it up on Endeavor or Atlantis.

But today we got the marvelous news that instead of having to truck tons of water of space, the astronauts can just drink their own pee! (Yay?) Today marked  a successful test of the International Space Station’s water recycling system. The astronauts marked the occasion by raising a baggie (no glass in space) of recycled water (née urine) in a toast,  and taking it a sip. They deemed it delicious, and, after taking a few questions from reporters, went about their day.

It’s a constant on SciNoFi that we do one post per episode of a given show. But as we all now know from watching the unexpectedly epic season finale of Fringe last week, constants can change, universes collide, and worlds are as multitudinous as the stars in the sky. And really, none of that was a spoiler.

But this whole question of varying physical constants has been roiling the scientific community for years, especially the astrophysicists who really have their telescopic fingers on the cosmic pulse of the question. As all of us who ever took a high school sicen class know, physical constants are crucial to making a great many descriptive equations actually work.  In Einstein’s E=mc², the c is the constant, it’s the speed of light. Then there’s the Planck constant, Avogadro’s number, and on and on. But if those numbers suddenly turned out to be changing, then how would the equations still work? Would science be broken?
