Derailed by a handrail

NASA's floating albatross, which goes by the name International Space Station, continues to give the agency headaches. Astronauts currently living on the space station were prohibited to do spacewalks last week because of flawed handrails. Yup, that's right - astronauts wasn't able to perform spacewalks because NASA discovered that the handrails, which is used to tether astronauts to prevent them from flying off, were flawed. The agency has devised a new method for spacewalks from now to compensate.
