It made me laugh that art imitating life imitating art. My name's Chris Hadfield, Colonel in the Air Force, astronaut, flew in space three times, commanded the International Space Station, did two different space walks, used to be a test pilot and engineer, downhill ski racer, occasional guitar player, and we're here today to look at some scenes from different space movies. - [Astronaut] You need to detach. I can't see you anymore. Do it now. - I'm trying. [intense music] [astronaut yells] - Ugh. This is "Gravity", and this is the scene where the space shuttle explorer is orbiting the earth and they're doing repairs on the Hubble telescope, and they go through some sort of asteroid debris field. Okay, well that's a nice concept. And the visuals are great. But what happens is so far from reality that I just, I want to turn my head. First off, this satellite goes whizzing by at about, I don't know, maybe 120 miles per hour. Satellites are going five miles a second, 17.5 thousand miles an hour. How that thing where you can, oh, you can identify the satellite going by. And then, it's like some big dump truck just suddenly put this big pile of rubble just upwind of the space shuttle and suddenly it looks like an avalanche in space has poured in front of this shuttle. And they violate the laws of physics when Sandra Bullock, she's on the end of the big cannon arm, the big robot arm, and it's tumbling, and she releases her little straps, and suddenly, whoosh, she flies away in a while new direction like there was some force on Sandra that wasn't on the arm. How come she has a different gravity than the arm does. And then everybody in the crew, I mean, the dialogue, they're all yelling back to Houston as if somehow Houston's going to help them right here. [astronaut yells] - [Astronaut] Houston, I've lost location on Dr. Stone. - And George Clooney is referring to this other astronaut as Dr. Stone, like they haven't really met each other yet. And he's asking permission from somebody, I don't know, to go and help her out in the, I mean, it's not astronaut behavior, it's not logical behavior, it's so execrable from actual practical demonstration of what the reality of space flight is like. The most experienced astronaut in American history is a woman. It's Peggy Whitson. She's been in space longer than any other American. She commanded the International Space Station twice, she's done 10 space walks, she was NASA's chief astronaut. In this movie, Sandra Bullock has only been an astronaut for less than a year, and when she's faced with a problem, she's panicking and has no idea what to do, and George Clooney is driving around like some sort of space cowboy as the only person that really knows what's going on, and it's like they met when they were out on this space walk. And then it's like, he's trying to pick her up during a space walk. - Prototypes, even for your pretty blue eyes. - What is he even doing out there, driving around in his jet pack. I mean, we don't go outside recreationally. It's so different than the actual people that are exploring space that devote their lives to being astronauts that are actually on the Space Station right now. The wonderful human role model examples we have of people who are doing these things. I think it set back a little girl's vision of what a woman astronaut could be an entire generation. Sandra Bullock did a great job of portraying this character in the movie, but I just think the character that they wrote for her was really disappointing. That's what I would've changed. Get the characters right, get it to represent what astronauts are actually like, and then build the story around that. Don't just make it the perils of Pauline, where she's strapped to the train tracks, and she needs George Clooney to magically appear next to her to tell her which book to open to be able to do the right thing. Real astronauts recognize the seriousness of their job. The fact that it's always life or death, and that we're there as the representatives of 7.5 billion people. Everybody's trusting us to be good at this, to have spent decades getting good at this. If you want to know what a space walk looks like, there's never been a better movie though than "Gravity". That opening scene is magnificent for the visual impact and the beauty of the silent turning world and the resolution of each of the fine things and the lighting, it's wonderfully good. It gives you the raw emotional sense of a space walk. Just don't pay attention to what the astronauts are actually doing. [dramatic music] [computer beeps] This movie is "Passengers", so if you're gonna get on a ship and you're gonna be on it between stars, going to settle some planet in another solar system, you can't be floating weightless the whole time. Who knows what your babies would be like if they were conceived and developed and tried to grow without gravity. Their bodies wouldn't grow right. How do you make gravity if there's no planet nearby? One way of course is just like we do in a little experiment where we spin it in a centrifuge, you can spin the whole ship, and then everybody is pinned against the outside of the ship just by the centrifugal force, and that feels like gravity. If you shut off the spinner, then it would continue to spin for quite a while. There's really nothing to slow the spin down, and that's one of the big scenes in "Passengers", the ship has a problem, it stops spinning, and therefore, everything becomes like on the International Space Station and starts floating. I'm not sure why, when it starts losing power, the ship suddenly starts slowing down. You'd actually have to put big brakes onto it to stop all of that metal from spinning. I'm not sure why the ship didn't just blithely keep on spinning as it drove into the asteroids, but it would've been a worse story if that had happened. Let's say, all right, the ship stops spinning, now everybody's got no gravity, and one of the characters is in a swimming pool. What happens to water without gravity? Onboard the International Space Station, we played with water all the time. You could squirt it and it would just float there in front of you. It naturally, with the surface tension, goes to a perfect ball. That's the easiest shape for it to go. If you had a swimming pool held in place by gravity, and then the gravity went away, the water would have some inertia as the ship slowed down, and it would slosh, but then the water would almost look like a big blob slowly forming itself into a ball. And I think that's quite well shown. And the weirdest thing is if you were in the water at the time, how would you even know which direction to swim? Which way is the surface if there's no up or down? Even if you started swimming one direction, the blob is flexing, and the way you're swimming might be getting further away from you. That was a very compellingly accurate scene, assuming there's a swimming pool on board a spaceship. The way it resolves though, it bends the edge of probability because if you spin the ship back up again, then you generate the centrifugal force, and the water would get squished back down into the pool side of the room, but it would take a lot of force and time to take a ship that is stopped, this great big massive metal thing, and get it spinning again. It wouldn't be like nothing, and then bang, gravity, like it's portrayed in the movie where suddenly everyone is going, bang, into the floor, as if gravity was an on/off switch. But that wouldn't haven't been as visually compelling and allowed the crew member, the young lady, on her last dying breath to burst out of the water and stay alive. [dramatic music] [spaceships buzz] - I'm going in, I'm coming in hot. [Chris laughs] - We're coming in hot. Oh yeah, okay. This movie is "Armageddon", which is the disastrous end of everything, and I think that's an appropriate name for this movie. I haven't seen it since I turned away from it when it first came into the theaters. This scene here where the two space shuttles are landing on an asteroid with the deep sea worker blaster guys who are gonna blow up the asteroid so it doesn't destroy earth. There are so many things wrong with this that I don't even really know where to begin. Let's start with the fact that they're talking to mission control real time. There's no lag. How did suddenly time and space change, you get instantaneous communication all the way out to this asteroid with no lag? And then, one of them says, "We're coming in hot." We're coming in hot? Relative to what? What are you talking about? And how do you know that? Do you have some magical landing information about an asteroid so that you know you're going faster than you meant you were supposed to? And then if you watch as the shuttle comes in to land, it flairs, like it slows down so it can touch down on the asteroid, like by pulling back on the stick. There's air on an asteroid? I mean, what made that magically happen? And there's these weird video game displays in the space shuttle that allow you to, like suddenly you're flying in the game Asteroids, and the crew, ah, everybody is panicked and yelling at each other. [crew yells] The big engines on the back are constantly running. Where's the fuel coming from? There's no gas tank. So they'd be accelerating the whole time. Why, I mean, what are they doing that for? It is as atrociously bad as any space movie that was ever done. It's so bad, it's tragic comic. I'm glad they safely landed on the asteroid, but it's just atrocious. - What's the abort force? - 7500.
