This Saturday marks the 25th anniversary of Warhammer 40k, which is sort of a big deal if you’re male between the ages of 13 and 60 who digs sci-fi violence and the sweet, seductive scent of acrylic paint. The franchise kicked off in 1987 as a sci-fi take on Games Workshop’s fantasy tabletop game “Warhammer.” From there, it steadily sucked in sci-fi influences to become its own distinct world: novels, movies, video games and of course vast armies of tiny soldiers.

I grew up painting figurines and playing war games with my dad, so I have a warm place in my heart for Games Workshop. But the don’t pay me to reminisce. They pay me to bring the science. So here, for your enjoyment, are five sciencey reasons to be thankful for the Warhammer 4oK universe:

I would have written this post earlier, but I was too worried I’d jinx my second shuttle launch attempt if I got cocky and started handing out advice and whatnot without ever actually having watched one lift off. Now that I’ve seen Endeavor safely into the sky, however, here goes. Because while seeing a shuttle launch wasn’t easy, and it wasn’t cheap, it was so amazing it brought tears to my eyes. I’m tearing up a little now just reminiscing about it. And to any aeronautics enthusiasts out there who are debating, I have to say, it was well worth the effort and expense. 100 percent. The experience is incredible, and now that I’ve seen a shuttle blast off into space, I can’t imagine passing up the chance while I had it.

So for anyone out there harboring the dream, you have one more shot with the space shuttle Atlantis (tentatively targeted for June 28 or possibly mid July) and I’ll give you the lowdown on what I found works and what doesn’t after the jump.

You asked: Is it possible to turn Mars into another Earth? Marshall Brain answers: The process of turning mars into an earth-like planet is called terraforming. However, Mars could ever be exactly like earth. To turn Mars into another earth it needs: – More gravity – More water – More atmosphere – Higher temperatures – [...]

The space shuttle Discovery took off for what’s likely the last time yesterday, and it got me thinking about the future of space travel, especially in the form of tourism. More specifically: affordable space tourism. Virgin Galactic is going to be offering flights soon, for example, but at $200,000 a pop, that’s a little more than my wallet — and bank account, and 401k, and Roth IRA, combined — can handle. So how much longer do I have to wait here?

Ever since the movie “2001: a Space Odyssey” came out (back in 1968, before humans had landed on the moon), people have been ready to head out into interplanetary space: Now NASA has drawn up a realistic ship to do this sort of interplanetary travel in real life. It’s called the Nautilus-X MMSEV (Multi-Mission Space [...]

Whether you’re a marathon runner, a dayvan cowboy or an interstellar spaceship, you’re going to need to refuel along the way. Marathoners can just reach out and accept a cup of water from volunteers, and countless gas stations await pit stops from road-tripping van enthusiasts. But just where’s a star ship supposed to tank up on fuel? The fusion runway concept offers one possible answer. I chatted with Tau Zero Foundation writer Paul Gilster on just this topic the other day and yes, scientists have given some serious thought to the fuel woes of interstellar travel.

Have you ever watched an action hero fly through the air, propelled in slow motion by the massive explosion erupting behind them? This slice of cinematic cheese gives you a decent taste of how NASA considered propelling spacecraft in the 1950s and 1960s.

Dubbed Project Orion (not to be confused with NASA’s more recent Orion spaceship project), this crazy-sounding propulsion system depended on nuclear warheads. You read that right, not mere nuclear power but actual nuclear detonations.

If nothing else, the Skylon space plane is ambitious. It will be a shuttle-like vehicle with wings and a cargo bay, and it is reusable. However, it will take off from a runway and be able to turn around for its next mission very quickly…

You Asked:

Can we send rockets outside our solar system? — Sahil, Pune, India

Marshall Brain Answers:

Yes, we can send spacecraft outside the solar system. And we have two spacecraft that are heading toward interstellar space now. These would be the two Voyager spacecraft. Find out more after the jump.

Chances are that you are sitting in a chair right now, so it seems like you are stationary. But in fact you are moving through the universe at a tremendous speed at this very moment. Let’s take a look at where all that motion is coming from. The first thing to consider is the earth’s [...]
