Spacecraft, Heal Thyself

carpdeus writes "The European Space Agency, citing the fact that we don't glue ourselves together when we nick ourselves, has funded a study toward creating a spacecraft that could fix itself. By replacing a few of the fibers in the resinous material that make up a spacecraft's skin with hollow fibers containing adhesive, the material has a chance to fix itself when it encounters minor damage, much the way our skin does when blood wells up and clots. While admittedly years away, such material makes longer duration missions a possibility."
