Astronauts Forced To Take Shelter From Space Junk

An anonymous reader writes: Three astronauts living at the International Space Station were forced to scramble to safety Thursday after a "close pass" by flying Russian space debris. The men decamped into the Soyuz spacecraft, which is attached to the orbiting station, while a chunk of an old Russian weather satellite passed 1.5 miles away. Flight engineer Scott Kelly tweeted: "Happy there was no impact. Great coordination with international ground teams. Excellent training."

      Really cool movie.

      Yes, but with lots of inaccuracies.

      Yeah, saw it, and read the article. Now... parts of the movie are NOT as inaccurate as you might think...

      Time (and Neil deGrasse Tyson, who also took issue with the film's accuracy or lack-thereof,) both got this basic point wrong: They both basically stated that there's no way that would/could happen because they're in different orbits. (Tyson also pointed out that nothing orbits in that direction anyway, which is also right, but simultaneously wrong.)

      They both failed to consider the possibility of something going horribly, catastrophically wrong. Sure, in the course of the film they neglected this possibility but... suppose a Russian satellite launch aimed and intended for a higher and faster orbit, (fast in terms of tangential velocity, NOT orbital period,) but that something went wrong with the vehicle during the initial boost phase. Suppose first that the controllers have no means to control or abort/detonate the launch. Compound that with the craft heeling over the wrong way, (something wrong with guidance,) and accelerating into orbit in the wrong direction.

      This could easily happen. Now of course, it would not be able to get as high, since instead of benefiting from the starting rotational velocity of the Earth's rotation, it instead has to COUNTER that to get into space. Not that hard, actually, it simply means that when the craft shut down the engine, it would be traveling about 2000 miles per hour or so more slowly than it would have, tangentially with respect to the Earth, (about 1000 mph each for missing the rotational assist, and for having to OVERCOME the same by flying in the opposite direction,) roughly. That simply means a somewhat lower orbit, and it WOULD be in the wrong direction. Now suppose the system later realizes there's a mistake OR it plows into something? End result? A counter-orbiting debris cloud, (depending on how and when it was initially destroyed) of deadly satellite shrapnel that also, oh, P.S., by the way, would slowly de-orbit spontaneously if it were low enough, periodically to encounter the occasional stray wisp of atmosphere, as occurs in very low Earth orbit.

      (If you're having trouble understanding this, consider this. A kid on a skateboard traveling 5 miles per hour north, throws a softball at 35 miles per hour with respect to him. The speed of the ball when it leaves his hand with respect to the ground is 40 miles per hour. If however, he turns around and is now facing south, and throws the ball with the same force, it ends up going only 30 miles per hour with respect to the ground. Slower, sure, but it will be going SOUTH this time. If it was supposed to be going NORTH, it is going the wrong way now. Since escape velocity of the Earth is VASTLY higher than the tangential velocity that can be used or must be overcome at the Earth's surface, depending on which way you're launching, this is an easily possible scenario. Everyone launches pretty much the same direction of course because for one thing, it's cheaper, and also it means everything else is going the same way you are, vastly reducing the odds of a collision.)

      Or so I've heard. What do I know, I'm not a fancy rocket scientist or astrophysicist. Just an eff'ing engineering student. The crux is, when you consider whether or not a situation is possible, you don't consider ONLY if YOU know how it COULD happen, but whether or not there is any reason why it COULDN'T. In this case, there's no reason why it couldn't. There are plenty of reasons why it wouldn't, but NO reason why it couldn't, in point of fact.

      Sure, everything orbiting in a given orbit is going the same way, ONCE IT SUCCESSFULLY GETS TO ORBIT! That's kind of the point. The "Gravity" scenario starts off with a lot of things going WRONG.

    I propose that we launch a ion drive satellite that can change orbits at will and use magnets and electrostatic and physical means to capture space junk and dead satellites and either deliver them to a garbage depot in orbit for recycling or place them in a de-orbit trajectory that will use the gravitational influence of still active and maneuverable satellites to de-orbit further.

    (It is known that when an object in a lower orbit and an object an a higher orbit pass by each other the gravitational influence of the lower, faster moving object loses energy to the slower moving, higher orbit object, thereby causing the lower object to slow down and move into a lower orbit and speed up the higher orbit object pushing it into a higher orbit.)
