What are the most dangerous spacewalks?
I've heard more than once that the spacewalks are very dangerous because astronault only connects the spacecraft for a small line and, if the line is somehow separate the astronaut lost in space. This raises the question: why are not liable for the astronauts with a stronger line or a backup? Is this a legitimate concern or is there other aspects of the much more dangerous spacewalk?
I doubt that our technology can make a stronger belt – given the limitations (which must be very flexible and fit in a vacuum and extreme heat and cold). That's not a big risk. In addition, the astronauts always carry a small rocket maneovering (think in a really jazzed-up Water Gun that fires a gas such as CO2), and other security features. There are other hazards – most of them minor: a) Extreme temperature (-250 to 250 F) – but that is relatively easy to deal with good insulation, b) micrometiorites – the suits have an outer layer to protect the astronauts. And the chances that a big enough hit to hurt them is very small. I guess that will happen over time. But the odds of being beaten by a car are much higher, c) radiation. Its relatively low land near (the Earth's magnetic field for most of it) – that 's going to be a concern as they start making more trips outside the vicinity of Earth, however. NASA is working on technologies of protection now. The greatest danger is a leak Space Suit – a tear, puncture, nothing. Emergency teams have patched – but it is a hole big enough, they could lose their air pressure efore that could stop the leak. So far, that has never happened – keep your fingers crossed.
