As reported by my fellow DISCOVER blogger Eliza Strickland, researchers believe that the moon may have considerable amounts of water ice. But Tintan fans have known this since 1954, which is when Hergé published the second half of his Destination Moon two-parter, Explorers on the Moon: during a moonwalk, Tintin discovers a cave with a floor of ice.
Okay, okay, admittedly the ice suggested by Eliza’s researchers isn’t just lying around — it’s bound into lunar rocks. But it is another prop for the Destination Moon books, which have held up surprisingly well over the decades, especially given that they were published three years before Sputnik I and 15 years before the Apollo moon landing.
Written with a desire to get the science and technology right (for example, in the first book, Destination Moon, an explanation of how a nuclear reactor burns uranium fuel is given that was not materially different from the version I found in physics textbooks years later, and which was somewhat better presented), the books feature a nuclear-powered rocket that uses Von Braun’s original Direct Mode mission plan to get to the moon (no mucking about with lunar landers, or rendevousing with booster stages in Earth orbit when you have a nuclear engine!). Acceleration couches support the crew, whiskey forms into little balls under its own surface tension in zero gravity, and reduced lunar gravity complicates walking.
Of course, there are lots of inaccuracies one could pick at, but to my mind Tintin’s discovery of ice is emblematic of why the books hold up so well. Hergé could easily have chosen to have Tintan discover the ruins of a lost civilization, or giant mushrooms, or any one of a number of things that are a lot more dramatic and cartoonogenic than ice. But by making the discovery of ice the scientific highlight of the mission, Hergé grounds Tintan’s fantastic adventures in reality, and gives the books the ring of truth.
A recent episode of the “This American Life” podcast (episode #329: “Nice Work If You Can Get It”) opens with an amusing rundown of what astronauts actually spend their time doing now that there are almost no manned spaceflights. The answer was mostly: go to lots of meetings in Houston.
The more interesting revelation was that the astronauts get their vicarious space thrills by watching Farscape and Battlestar Galactica. Aside from being “hugely jealous” of the capacity for interstellar space flight, one of the astronauts pointed out that classic BSG Viper/Star Wars X-Wing Fighter design is pretty dumb:
“All of those shows assume that there is some sort of magical gravity thing so that when you’re in your vehicle, you know, everybody’s all walkin’ on the floor. Well, not in our space program.
“They’ve got fighter jet flying. They have pointy noses and wings and they make them look like fighters. None of that is any advantage when there’s no atmosphere.
“You could be a box and have the same maneuverability. The Borg had it right. They’re a big cube and they’re perfectly maneuverable, as opposed to the little star fighter with the pointed nose and the wings and the engine in the back.”
In Pixar’s robot love story WALL-E, the Earth is surrounded by a dense field of orbiting junk. (Incidentally, you know you’re a geek when you’re the only one laughing in the cinema because you recognise one of the satellites that WALL-E has to brush out of his way as Sputnik 1.) But while things today aren’t quite as bad as depicted in WALL-E, space debris is still a big problem, as can be seen on a real plot from NASA of the junk orbiting overhead.

Pixar worked its magic this weekend, shooting to the top of the box office for the ninth consecutive time with WALL-E. And deservedly so–the movie pulls you into its world, and anybody whose heart doesn’t go out to the title character has a soul made of burnt toast. WALL-E is the name of the last robot left cleaning up the garbage-strewn Earth. All the humans left for an intergalactic cruise while the planet was getting spruced up, but the cruise has been going on for 700 years now with no end in sight.
Used to being pampered by robots and never leaving their hover-chairs, the humans have gotten a little bit portly over the centuries, and now find it difficult to even walk (if it ever occured to them to do so). Which is a problem that lurks in the minds of the people who are planning real-life expeditions to Mars.

Early on in the latest Indiana Jones installment, Dr. Jones survives the blast from a nuclear explosion by hiding in a lead-lined fridge. Oddly enough, this may be one of the more realistic stunts in the movie.
When we think of nuclear explosions, we tend to imagine a fireball that annihilates absolutely everything within a certain radius. But in fact it is possible for man-made objects to survive an atomic blast, relatively intact, in even the heart of the nuclear explosion. During a 1954 15-megaton atomic bomb test, two steel balls covered in graphite were hung from the bomb tower. Incredibly the balls survived—but were thrown a considerable distance from the bomb site. This led scientists, including the famed Freeman Dyson, to consider the possibility of using nuclear bombs to propel spacecraft through space.

Some of the characters on Battlestar Galactica have been tooling around on a sewage recycling ship recently. Not surprisingly, the onboard accommodations are less than four star. Still, however the characters might feel about it, whenever I’m watching a show with scenes set on a spaceship, the messier the interior looks, the happier I am. Unless a spotlessly clean spaceship is being used for specific plot point (“A key member of the crew offends the obsessive-compulsive plant people of Nebulan Six by failing to use a coaster when ritually offered a glass of ice-cool Krotj”) the problem is that spic and span spaceship interiors break down my suspension of disbelief just as quickly as watching a cardboard background tremble at the approach of a castmember.
