Stuck Knob Causes Serious Window Damage To Atlantis

Posted by timothy on from the for-want-of-a-nail dept.

FTL writes "While in orbit a metal knob floated between a window and the dashboard of Atlantis. Once back on Earth, the shuttle contracted, wedging the knob firmly in place and damaging the window. Initial attempts to free the knob have failed and engineers may need six months to disassemble that section of the orbiter. Given that the shuttle program will probably end next year anyway, such a delay might mean scrapping Atlantis early rather than repairing it. Efforts to remove the knob using less invasive techniques continue."

    Or is that only an outer protective layer? I know I've seen pictures of the pitting that micrometeors and paint flecks have caused on the Shuttles while in orbit, I just assumed they were made to be easily replaced.

      Why not spray a sealant around the surrounding materials, lay in an extraction nozzle attached to a pump, pour a mold around it then use a chemical to dissolve the metal, at least the edges of the metal, enough to remove it? No vibrations, no pressure, no crazy coolant or heating solutions. You can pick a site to work on that is least risk, such as the area in contact with the glass (assuming the glass isn't affected by the chemicals dissolving the metal).
